3 New Year’s Resolutions on Behalf of Pain Patients

By Crystal Lindell

It’s now 2026, which means I’ve spent too many decades making mostly failed New Year’s resolutions for myself. So this year, I’m not going to bother.

Instead, I have some New Year’s resolutions for other people. Specifically, they’re for people with power, like doctors and healthcare policy makers.

After all, it really seems like they need to make some policy changes, given the current state of things for people in pain. Perhaps they are just waiting for someone to tell them what those changes should be. 

Below is a look at three of my 2026 New Year’s resolutions on behalf of pain patients..

Resolution # 1: Fully Legalize 7-OH and Develop New Edibles

There’s so many conflicting local regulations when it comes to kratom and 7-OH, despite the fact that neither one is as harmful as health officials and lawmakers often claim.

For those unfamiliar, 7-OH is short for 7-hydroxymitragynine, an alkaloid that occurs naturally in kratom in trace amounts. Some kratom vendors now sell concentrated versions of 7-OH to boost its potency as a pain reliever and mood enhancer.

A lot of pain patients find both 7-OH and kratom to be effective at treating chronic pain. And while I am glad that both are still legal in most places in the United States, I would really like to see them fully legalized across the country, as municipalities and states realize just how beneficial these products can be.

I also would really like to see 7-OH vendors come out with some new edible formats, like chocolates, gummies and even seltzer.

I think 7-OH in particular has the potential to help a lot of people who have been denied adequate pain treatment. However, many of them may not be comfortable figuring out where to buy and correctly dose a 7-OH chewable tablet, especially if they are among one of the largest demographic of pain patients: the elderly.  

I think of my grandma trying to get 7-OH tablets at a local smoke shop, or having to figure out how to order them online. Both options are bad. 

Ideally, regular grocery stores and local pharmacies would have a display of low-dose 7-OH chocolates available over-the-counter for pain patients like her.

Resolution # 2: Stop Prescribing Gabapentin and Tramadol for Pain

This would be such a relatively easy change for doctors to make, and there’s so much science to back it up.

In October of 2025, PNN covered a study showing that tramadol is often not effective for chronic pain. And PNN has long been covering how ineffective gabapentin is for most pain conditions.  

However, despite the evidence, doctors still regularly prescribe gabapentin and tramadol for chronic pain. 

It doesn’t have to be that way. Doctors have alternatives that actually work, most notably low-dose hydrocodone. Yes, there are more regulations around that medication, making it more difficult to prescribe. But actually giving pain patients real options shouldn’t be so difficult.  

So, I would like doctors and other healthcare professionals to make it their goal to stop prescribing ineffective medications. Instead, offer pain treatments that actually work. Your patients will thank you.

Resolution # 3: Implement Medicare for All

Yes, I know this one is kind of unrealistic. But that’s what New Year’s magic is all about —  putting whimsical ideas out into the universe with the hope of seeing them come to fruition. 

After all, it can’t happen if we never ask for it.

Unfortunately, as the year starts off, we are actually heading in the opposite direction, with many Americans seeing their health insurance premiums soar or even deciding not to buy coverage. 

But I’m hoping that may be the catalyst we need for the public to start demanding real change. Right now, millions of people are losing their health insurance because the Trump administration ended federal subsidies for coverage under the Affordable Care Act. 

It’s an awful and unnecessary situation that our policy leaders have the power to fix, if only they worked together on the issue.

Every human should have the right to healthcare, and Medicare for All would go a long way to making that happen.

I know a lot of these resolutions probably won’t come to fruition in 2026, but I do think they could realistically happen before we start the next decade. And all of them have the potential to vastly improve the lives of millions of people living with chronic pain.

Happy New Year everyone. May your 2026 be filled with low-pain days, too much joy, and lots of love.

The 5 Most Popular PNN Stories of 2025

By Crystal Lindell

Looking back at 2025, there was a lot of news to cover when it came to chronic pain and illness. Access to opioids was again a major concern for our readers, but there was also a lot of interest in the potentially harmful effects of gabapentin.

Below is a look at the top 5 most widely read articles that PNN published in 2025.

We truly appreciate every time you read, comment and share our articles. And we can’t wait to bring you more great coverage in 2026! 

1) Over 15 Million Americans Prescribed Gabapentin Despite Warnings

In September, we covered an analysis by CDC researchers that showed that the use of gabapentin (Neurontin) continued to soar in the United States — usually for chronic pain and other health conditions the drug is not approved to treat. 

Gabapentin is the fifth most prescribed drug in the United States, with prescriptions nearly tripling since 2010, according to findings published in the Annals of Internal Medicine. The number of patients prescribed gabapentin reached 15.5 million in 2024, up from 5.8 million in 2010.

2) Cannabis Use by Older Adults Linked to ‘Younger Brains’ and Improved Cognition

In August, we covered a study that showed that cannabis use by older adults slowed the aging of their brains and may even improve cognitive function.  

An international research team analyzed health data on more than 25,000 adults in the UK, looking at the relationship between cannabis use, aging, and cognitive function. They found that cannabis users had brain characteristics “typically associated with younger brains” and “enhanced cognitive abilities.”

3) 6 Things to Try If Your Doctor Won’t Prescribe Opioid Pain Medication

A lot of pain patients find that their doctors are reluctant to prescribe opioids. So in February, I shared six things to try if your physician tells you to go home and take ibuprofen.

The first tip is not to give up. Tell your doctor what poorly treated pain is doing to your life – that you’re unable to work or that you may have to go to the emergency room. Tell the truth and don’t exaggerate, and you just might get them to change their mind.

Another option is to try kratom and/or cannabis. They don’t work for everyone, but many patients say they provide some level of pain relief.

4) DEA Plans Further Cuts in Oxycodone Supply

In November, we covered the DEA’s plan to cut the supply of oxycodone by more than 6% in 2026, along with marginal reductions in the supply of hydrocodone, morphine and other Schedule II opioids. 

From year-to-year, the cuts may not appear significant. But over the past decade, there has been an historic decline in the nation’s opioid supply. If its current plan is adopted, DEA will have cut the supply of hydrocodone and oxycodone by over 70% since 2014.

The DEA says the “medical usage” of prescription opioids is declining, when in fact the “medical need” for them is actually increasing.

5) Study Links Gabapentin to Increased Dementia Risk 

In July, we covered how gabapentin (Neurontin) may significantly increase the risk of dementia and cognitive impairment, even for middle-aged patients who only took the nerve medication for six months.

That was according to research published in the Regional Anesthesia & Pain Medicine journal, which looked at health records for more than 26,000 U.S. patients with chronic low back pain.

Researchers found that patients with six months or more of gabapentin use had a 29% higher risk of developing dementia and an 85% higher risk of developing mild cognitive impairment

Gabapentin’s Side Effects May Lead to ‘Prescribing Cascade’

By Pat Anson

Over the years, we’ve published many warnings about gabapentin (Neurontin), a nerve medication that is widely prescribed off-label for pain conditions it was never intended to treat. 

Common side effects from gabapentin include brain fog, dizziness, weight gain, headache, fatigue, and anxiety. The drug has also been linked to a higher risk of dementia.

According to a new study, those side effects may lead to a “prescribing cascade” in which physicians mistakenly prescribe unnecessary medications to a patient that cause even more side effects. 

The problem is not limited to gabapentin, but includes other nerve medications such as pregabalin (Lyrica), which are collectively known as gabapentinoids. Both medications may cause edema – fluid retention and swelling in the legs and feet –  leading doctors to suspect congestive heart failure and prescribe diuretics that can cause kidney injury, light headedness, and falls. 

Researchers with the VA Health Care System and the University of California, San Francisco (UCSF) analyzed the medical records of 120 older veterans, most of whom were male and long-term users of five or more medications. All had taken gabapentinoids and diuretics, which are often prescribed for edema.  

Although none of the veterans had fluid buildup in the year before they started taking gabapentinoids, only 4 doctors suspected the drugs were the culprit and just one discontinued the medication.

The vast majority of physicians – 69 in all – never suspected or downplayed the possibility that gabapentinoids may be causing the edema. Since fluid retention is a symptom of congestive heart failure and poor blood circulation, the veterans were put on loop diuretics such as Lasix.

Within two months, 28 veterans had side effects from the new drugs, including poor kidney function, dizziness, and blurred vision, along with low levels of sodium or potassium, which can disrupt critical body functions. Six patients had symptoms so severe they were hospitalized or taken to an emergency department. 

“Gabapentinoids may be prescribed at unnecessarily high doses or for conditions that they may not help,” said Matthew Growdon, MD, an Assistant Professor of Medicine at UCSF and first author of the study in JAMA Network Open. “In these cases, doctors should consider not prescribing these drugs — or giving lower doses to lessen the risk of prescribing cascades and other side effects.” 

One veteran in his 60’s was put on a heavy dose of gabapentin for neuropathy that was induced by chemotherapy for lung cancer. He developed edema and was switched to pregabalin. When the fluid retention didn’t stop, he was put on a diuretic. Within two days he developed light headedness and felt off-balance, and the diuretic was stopped.

Another patient in his 60’s was prescribed gabapentin twice a day for back pain, an off-label use. After two months he had edema and was put on a diuretic. Soon after, he experienced a fall, went to the ER, and was given IV pain medication. The diuretic and polypharmacy are believed to have contributed to the man falling.

The cases highlight how a prescribing cascade with multiple drugs can have serious health consequences. Patients on gabapentinoids may be prescribed sleep aids, anti-depressants and other medications to counteract the drugs’ many side effects.

Gabapentin is often prescribed off-label for migraine, fibromyalgia, cancer pain, postoperative pain, and many other pain conditions for which it is not FDA-approved. Off-label prescribing is legal and sometimes appropriate, but has reached extreme levels for gabapentin. Studies estimate the drug is prescribed off-label up to 95% of the time. 

“Gabapentinoids are non-opioids, and prescribers associate them with a relatively favorable safety profile,” says senior author Michael Steinman, MD, a Professor of Medicine at UCSF.  “Patients taking them should regularly check in with their doctor to assess whether this is the best treatment for them and consider other options, including non-drug alternatives that might be more appropriate.” 

In 2024, gabapentin was the fifth most prescribed drug in the U.S., with prescriptions nearly tripling since 2010. The number of patients prescribed gabapentin reached 15.5 million in 2024, up from 5.8 million in 2010.

Over 15 Million Americans Prescribed Gabapentin Despite Warnings

By Pat Anson

The use of gabapentin (Neurontin) continues to soar in the United State, often for chronic pain and other health conditions the drug is not approved to treat, according to a new analysis by CDC researchers.

In 2024, gabapentin was the fifth most prescribed drug in the U.S., with prescriptions nearly tripling since 2010, according to findings published in the Annals of Internal Medicine. The number of patients prescribed gabapentin reached 15.5 million in 2024, up from 5.8 million in 2010.

Gabapentin was originally developed as an anti-convulsant. It was first approved by the FDA as a treatment for epilepsy and later for neuropathic pain caused by shingles. But it is also routinely prescribed off-label for depression, ADHD, migraine, fibromyalgia, bipolar disorder, cancer pain, postoperative pain, and many other conditions.

Off-label prescribing is legal and, in some cases, appropriate. But for gabapentin it has reached extreme levels, with studies estimating the drug is prescribed off-label up to 95% of the time. Gabapentin has been used to treat so many different health conditions that a drug company executive called it “snake oil.”

"This study highlights a slowed, but continued, increase in gabapentin dispensing from retail pharmacies in the United States," wrote lead author Gery Guy Jr., PhD, of the CDC National Center for Injury Prevention and Control. "As gabapentin dispensing continues to increase, particularly among older populations, prescribing physicians and advanced practitioners should be alert to the potential adverse effects of gabapentin."

Side effects from gabapentin include mood swings, depression, dizziness, fatigue and drowsiness.  A recent study found that gabapentin raises the risk of dementia.

Gabapentin has also become a street drug, after drug users found it can heighten the effects of heroin, cocaine and other illicit substances. Nearly 10% of overdose deaths in 2020 involved gabapentin, with most of those deaths also involving illicit opioids. A recent analysis of drug tests found gabapentin in over 13% of urine samples that tested positive for fentanyl.

“Although gabapentin alone is infrequently involved in fatal overdose, serious breathing difficulties may occur in patients with respiratory conditions or those using gabapentin in combination with opioids,” said Guy.

The CDC has a checkered history with gabapentin. The agency’s 2016 opioid prescribing guideline promoted gabapentin and its sister drug pregabalin as non-opioid alternatives for neuropathic pain, without any mention of their possible side effects.

The CDC’s revised 2022 opioid guideline is a bit more cautious. It says gabapentin can produce “small to moderate improvements in chronic pain and function,” but can also cause blurred vision, cognitive effects, sedation, and weight gain.

Medical experts say doctors need to do a better job warning patients about the side effects of gabapentin, and the medication should be stopped if a patient reports little or no benefit. They also think medical guidelines have exaggerated the effectiveness of gabapentin and should be revised.

Bad News Continues for Non-Opioid Analgesics

By Pat Anson

The bad news keeps piling up for non-opioid analgesics, which are often touted as safer and more effective alternatives to opioid pain medication.

A large new study found that pregabalin (Lyrica) raises the risk of heart failure in older patients, while Vertex Pharmaceuticals said it was stopping development of an experimental drug for post-operative pain because it was less effective than a low dose of hydrocodone.   

The pregabalin study, recently published in JAMA Network Open, compared the drug to gabapentin (Neurontin) among Medicare patients with chronic non-cancer pain. Both pregabalin and gabapentin are gabapentinoids, a class of nerve medication that was originally developed to prevent seizures in epileptic patients.

Because they are not opioids and perceived as safer, both drugs are now widely being prescribed for a variety of pain conditions, usually off-label.  

In a subset of patients with cardiovascular disease, researchers found that hospitalizations and emergency department visits for heart failure were more common in pregabalin users compared to patients on gabapentin. The difference wasn’t significant (18.2 visits vs 12.5 per 1,000 person-years), but it was enough for researchers to recommend caution when prescribing pregabalin.

“Practicing clinicians should undertake a careful assessment of ongoing cardiovascular risk factors and perform adequate risk-benefit counseling for older patients before prescribing pregabalin for chronic pain,” wrote lead author Elizabeth Park, MD, Columbia University Irving Medical Center.

Pregabalin is believe to be riskier because it binds to calcium channels associated with heart failure and arrhythmias. Both the American Heart Association and European Medicines Agency already list pregabalin as a drug that increases the risk of heart failure.

"The study serves as an important reminder that not all gabapentinoids are created equal and that in the pursuit of safer pain control, vigilance for unintended harms remains paramount," said Robert Zhang, MD, and Edo Birati, MD, in an accompanying editorial.

"For older adults with chronic pain, particularly those with cardiovascular disease, clinicians should weigh the potential cardiovascular risks associated with pregabalin against its analgesic benefits. This is particularly relevant given the growing use of gabapentinoids in older populations and ongoing polypharmacy issues in this age group."

The research doesn’t give gabapentin a clean bill of health, since it also raises the risk of heart failure in older patients – just not as much as pregabalin. Last month another study found that gabapentin increases the risk of dementia and cognitive impairment.

Researchers have long been concerned about the effects of gabapentinoids on the brain, while many patients have complained the drugs cause brain fog, dizziness, weight gain and mood changes. Despite warnings that they are overprescribed for conditions they were never intended to treat, the use of gabapentinoids continues to grow in the United States. 

New Analgesic No Better Than Vicodin

The new analgesic being developed by Vertex Pharmaceuticals – called VX-993 -- will apparently never reach patients, after the company announced disappointing results from a Phase Two clinical trial.  VX-993 is a non-opioid that blocks pain signals in peripheral nerves before they reach the brain, which means it doesn’t have the same “liking” effects of opioids, which can lead to addiction.  

When given to patients recovering from bunionectomy surgery, VX-993 was slightly more effective than a placebo in reducing post-operative pain, but provided less pain relief than a low dose of a hydrocodone/acetaminophen combination (Vicodin).  

“Based on these results, as well as the totality of preclinical data and results from our previous bunionectomy clinical studies, VX-993 is not expected to be superior to our existing NaV1.8 inhibitors and therefore we will not be advancing it as monotherapy in acute pain,” Carmen Bozic, MD, Executive Vice President and Chief Medical Officer at Vertex, said in a statement.

VX-993 acts similarly to Journavx (suzetrigine), a non-opioid developed by Vertex that acts on peripheral nerves. Journavx was recently approved by the FDA to treat moderate to severe acute pain, despite lackluster results in clinical trials that also showed it was no more effective than Vicodin.

The FDA’s approval of Journavx coincides with implementation of the NOPAIN Act, which makes non-opioid analgesics in outpatient surgical settings eligible for higher Medicare reimbursement rates. Journavx costs about three times as much as Vicodin.

Study Links Gabapentin to Increased Dementia Risk

By Crystal Lindell

Gabapentin (Neurontin) may significantly increase the risk of dementia and cognitive impairment, even for middle-aged patients who only took the nerve medication for six months.

That’s according to a new study, published in the Regional Anesthesia & Pain Medicine journal, which looked at health records for over 26,000 U.S. patients with chronic low back pain.

Researchers found that patients with six months or more of gabapentin use had a 29% higher risk of developing dementia and an 85% higher risk of developing mild cognitive impairment (MCI). 

Gabapentin was originally developed to prevent epileptic seizures, but is now commonly prescribed off-label as an alternative to opioids for pain management.

Researchers have long been concerned about gabapentin’s effects on neurotransmitters in the brain, while patients have complained the drug causes brain fog, dizziness, weight gain and worsens mood. 

Perhaps the most startling aspect of the study is that gabapentin increases the risk of dementia and cognitive decline in middle aged adults.

Dementia risk more than doubled and MCI risk tripled among 35–49 year olds. A similar pattern was observed among 50–64 year olds.

Risks also rose the more often patients use gabapentin. Those with 12 or more prescriptions were 40% more likely to develop dementia and 65% more likely to develop MCI than those with fewer prescriptions.. 

“Our findings indicate an association between gabapentin prescription and dementia or cognitive impairment within 10 years. Moreover, increased gabapentin prescription frequency correlated with dementia incidence,” wrote lead author Nafis Eghrari, a medical student at Case Western Reserve University School of Medicine.

“Our results support the need for close monitoring of adult patients prescribed gabapentin to assess for potential cognitive decline.”

As a patient who has taken gabapentin for chronic pain, these results are alarming to say the least. And I wonder if the findings would also apply to pregabalin (Lyrica) and other gabapentinoids in the same class of medications. I have also been prescribed Lyrica. 

I don’t believe I was ever warned that gabapentin could increase my risk of cognitive decline, despite the fact that was a known concern. I don’t know if such a warning would have deterred me from taking it, but that’s still a choice that should have been given to me. 

I am also concerned that the information about these very real risks associated with even relatively short-term gabapentin use will reach patients and prescribers. Sales of gabapentin and pregabalin have tripled from a decade ago, when they were first touted as safer alternatives to opioids. 

Gabapentin is FDA-approved for epilepsy and neuropathic pain caused by shingles, but is also prescribed off-label for depression, ADHD, migraine, fibromyalgia, bipolar disorder and postoperative pain.  

Anyone prescribed gabapentin for pain should be told that using the medication for just six months greatly increases their risk of developing dementia. However, I doubt that will happen. In my experience, while medical professionals are quick to point out the supposed risk of opioids like hydrocodone, they often push alternatives like gabapentin onto patients without much discussion. 

The assumption is always that anything must be safer than opioids. Unfortunately, that doesn’t always seem to be the case. 

A Non-Alcoholic Drink Can Help You Relax, Socialize and May Even Relieve Pain

By Madora Pennington

I am going for a month without drinking, not because I have a problem with alcohol or because alcohol is interfering with my life. I don't and it isn't.

I just got back from a long vacation, which included an 8-day all-inclusive cruise. We wanted to get our money’s worth. After weeks of drinking every day, it seemed only sensible to take a full break from alcohol. No one would argue that so much drinking is healthy.

I am not alone. You may have heard about the “sober curious” — those who abstain to see what socializing, stress, and life itself is like without alcohol. Young adults, overall, are drinking less alcohol. These trends are fueling the demand for non-alcoholic, yet interesting drinks that seem sophisticated or reminiscent of a cocktail.

But is there a non-alcoholic drink that also helps you relax and socialize? I found a company, Sentia Spirits, that makes beverages that enhance your body’s production of GABA

Don’t confuse GABA (gamma-aminobutyric acid) with the nerve pain medication gabapentin (Neurontin). GABA is a naturally occurring neurotransmitter that sends signals in the brain and spinal cord, while gabapentin is a synthetic variation of GABA. The medication acts similarly as GABA, but tends to cause many unwanted side effects. Benzodiazepines, SSRI antidepressants, muscle relaxers, and other drugs also affect GABA in the body.

Sentia’s beverages contain herbs and botanicals that improve mood, focus, calmness, and energy. Their concoctions taste more like bitters than a mocktail, but certainly provide an interesting experience for the palate.

I found them to be subtly relaxing, without the impairment of an alcohol-induced buzz.

GABA itself is also available in supplements that people take to relax and improve sleep. It may also help relieve pain. When GABA binds to pain receptors, it reduces the transmission of pain signals, potentially providing relief from various types of physical discomfort.

SENTIA SPIRITS

Research has found that low levels of GABA make it harder to keep negative emotions such as fear, anxiety and depression in check, and may also worsen chronic pain. As PNN has reported, Dr. Forest Tennant recommends GABA supplements for patients with intractable pain "to force damaged nerve tissue to correctly function and relieve pain.”  

As far as reasons for abstaining, alcohol worsens depression. And people with alcohol use disorder often have chronic pain, which means they could be self-medicating.

Using supplemental GABA or medications that promote it could be a useful strategy in managing the spiral of chronic pain on the body and brain. Many sources suggest taking GABA on an empty stomach to give it a better chance of reaching the brain.

Limiting alcohol intake might also be a wise choice for anyone. Certainly, finding ways to diminish stress and improve sleep should be part of pain management.

Sentia costs about $40 for a 500ml bottle, which is enough for 20 shot-sized servings. If you don't want it straight or want to make it look like a cocktail, you can mix it with tonic water.

Talk to your healthcare provider about your pain control regimen and how to improve it before taking GABA or any supplement.

I enjoyed my time of sobriety very much. I thought I would miss drinking, but did not. The sleepiness and haziness from a glass of wine is stronger than I realized, and it doesn’t make socializing more fun for me. I ended my sober curious time with a resolve to drink less overall.

Gabapentinoids Raise Risk of Hip Fracture in Older Adults

By Pat Anson

Many patients have learned – the hard way – that nerve medications known as gabapentinoids have over a dozen potential side effects, from brain fog and sleepiness to weight gain and mood changes.

You can now add hip fractures to the list.

A study at Australia’s Monash University found that gabapentinoids such as Lyrica (pregabalin) and Neurontin (gabapentin) significantly raise the risk of hip fractures, especially in older adults who are frail or have kidney disease.

The study, recently published in JAMA Network Open, tracked nearly 3,000 patients aged 50 and older who were hospitalized for hip fractures in Victoria, Australia from 2013 to 2018. Among those 80 and older, nearly 60% were prescribed a gabapentinoid before being admitted, with most of them using pregabalin (94%).  

After adjusting for comorbidities and the use of other medications, researchers estimate that people over age 50 have a 30% higher risk of hip fractures within 60 days of gabapentinoid dispensing. The risk is even higher for patients with chronic kidney disease (141%) and those with high scores for frailty (75%).

“Our results showed patients had 30 per cent increased odds of suffering a hip fracture within two months of being dispensed a gabapentinoid medication,” said co-author Simon Bell, PhD, Professor and Director of the Centre for Medicine Use and Safety at the Monash Institute of Pharmaceutical Sciences. 

“The link between gabapentinoids and hip fractures existed across different age groups but the odds of hip fracture was higher among patients who were frailer or had chronic kidney disease, so these should be important considerations when deciding when to prescribe gabapentinoids.” 

Bell and his colleagues did not establish why gabapentinoids raise the risk of hip fractures, but they suspect the medications increase the risk of falling in older adults, similar to other psychotropic drugs such as anti-depressants, benzodiazepines and opioids.

“Our findings highlight the importance of assessing each patient’s risk before prescribing gabapentinoids,” said lead author Miriam Leung, PhD, a Teaching Associate at the Centre for Medicine Use and Safety at Monash University.

Despite limited evidence of their effectiveness as pain relievers, gabapentinoid use has risen significantly in recent years for neuropathy, fibromyalgia and other chronic pain conditions. The drugs are also increasingly used for acute pain, such as postoperative pain and even dental pain.

A 2019 study found little evidence that gabapentin and pregabalin should be used for pain and said their effectiveness was often exaggerated by prescribing guidelines.

In the United States, nearly 5% of the adult population uses a gabapentinoid, while in Australia 1 in 7 people aged 80 and older is prescribed the nerve medication.

Genes May Explain Why Gabapentin Works for Some Pain Patients

By Pat Anson

Over the years, gabapentin (Neurontin) has been prescribed for dozens of health conditions, from epilepsy and fibromyalgia to depression and post-operative pain. It’s even been used to treat bipolar disorder. Gabapentin has been marketed for so many different conditions – at times illegally -- that a pharmaceutical company executive infamously referred to the drug as “snake oil.”

Even though it’s been approved for medical use for over 30 years, the UK’s National Health Service admits it’s still “not clear exactly how gabapentin works.”

A new study may finally help explain why gabapentin is an effective pain medication for some patients and an addictive drug with unwelcome side effects for many others.

It could be all in the genes.

Researchers at the University of Edinburgh took another look at a previous study of women with chronic pelvic pain to see why gabapentin worked no better than a placebo for most, but was a moderately effective pain reliever for about 40% of them.

Researchers took saliva samples from 71 women who participated in the study -- 29 who responded to gabapentin and 42 who had no improvement -- and found that the responders were more likely to have a variation of the gene Neuregulin 3 (NRG3). The gene is primarily expressed in the brain, spinal cord and central nervous system, and helps regulate pain sensation and transmission.

The findings, recently published in the journal iScience, may explain why gabapentin works for some women with chronic pelvic pain.

"A genetic factor that can predict how well gabapentin will work in patients offers the prospect of tailored treatment, and provides invaluable insights into understanding chronic pain. We hope eventually to use this genetic marker to optimize personalized treatment decisions and minimize adverse effects for women with chronic pelvic pain," wrote lead author Scott Mackenzie, MD, from the University of Edinburgh's Centre for Reproductive Health.

The study also has implications for other chronic pain conditions. Further research is needed to confirm the findings, but researchers say a genetic test for NRG3 could help limit the use of gabapentin to people who actually benefit from the drug.

"Isolating this single genetic marker is an important discovery that could ultimately help refine treatments for millions of women worldwide who suffer from chronic pelvic pain, as well as increasing our understanding of its role in other pain conditions. We believe this is an exciting opportunity for collaboration with a commercial partner who can help translate the research into a clinical setting," said Susan Bodie, PhD, Head of Business Development for the College of Medicine and Veterinary Medicine at the University of Edinburgh.

Gabapentin and other nerve drugs like pregabalin (Lyrica) have come under increased scrutiny in the UK because they are increasingly involved in overdose deaths.  

A recent analysis of drug tests suggests that gabapentin is also being misused in the U.S. Gabapentin was found in in over 13% of urine samples that tested positive for fentanyl -- about twice the number of drug tests in which prescription opioids were found.

Despite the risks of side effects and addiction, gabapentin is increasingly prescribed “off-label” for conditions it is not approved to treat, such as dental pain. A 2019 study found little evidence that gabapentin and pregabalin should be used for pain and said their effectiveness was often exaggerated by prescribing guidelines.

The CDC’s revised opioid guideline says gabapentin and pregabalin can have “small to moderate improvements” on pain, but with a moderate risk of side effects.

UK Crisis Grows Over Pregabalin Misuse

By Pat Anson, PNN Editor

Nearly 3,400 people in the UK have died from overdoses involving pregabalin in the last five years, according to an investigation by The Sunday Times.

One of them was a young man named Alex Cottam, who spiraled into drug abuse, addiction and a fatal overdose after he started taking pregabalin for anxiety and depression.   

“It’s hard to imagine somebody’s whole life revolved around a pill, but it did,” said Cottam’s mother, Michelle. “It completely changed him, like it was an obsession.”

The Sunday Times’ story about Cottam and other pregabalin users sparked a frenzy in British tabloids about the growing misuse of the drug.

“Our Pregabalin nightmare” was the headline in the Daily Mail, which shared the story of a woman with arthritis who said she “felt like I was losing my mind” after taking the drug for six months. Another woman told the tabloid she began seeing “dead people” within 30 minutes of her first dose.  

In a first-person account published in The Telegraph, Miranda Levy wrote about the severe withdrawal she experienced when she stopped taking pregabalin for depression.

“First came the pins and needles, closely followed by the sweating,” said Levy. “Add to this the progression of unremitting nausea, retching, diarrhea, jitteriness, dizziness so bad you can’t stand up and the feeling you’re about to die.”

Pregabalin – commonly known as the brand name Lyrica -- was never intended to treat anxiety, depression or arthritis. It was originally developed as an anticonvulsant that was first approved by the FDA in 2004 as a treatment for epilepsy. Since then it has been prescribed for dozens of painful conditions such as fibromyalgia and diabetic neuropathy, and is sometimes hailed as a “wonder drug” that is safer than opioids.

Pregabalin has helped some pain patients, but for many it’s also had severe side effects such as fatigue, insomnia and cognitive decline. Margaret Heath started taking pregabalin two years ago for Complex Regional Pain Syndrome (CRPS) and says it ruined her life.

"I've been on every type of morphine you can be put on... this is by far and away the worse drug to be on. It's worse than fentanyl. There is absolutely no comparison with the viciousness of the withdrawal of pregabalin," Heath told LBC News. "There would be days where I would not be able to do anything except lie there... it was debilitating."

Nearly nine million prescriptions for pregabalin were written in the US in 2021, the last year for which data is available. A similar number were written in England and Wales the following year, despite growing concerns in the UK that pregabalin is being misused to boost the euphoric effects of other drugs.

Pregabalin has become so popular with illicit drug users that it frequently appears in overdose toxicology reports. The number of fatal overdoses in the UK involving pregabalin has risen by nearly 11,000% since 2011, followed by a 3,275% increase in gabapentin-related drug deaths.    

UK Drugs With Biggest % Increase in Deaths (2011-2022)

DAILY MAIL GRAPHIC

Pregabalin and gabapentin (Neurontin) belong in a class of nerve medication known as gabapentinoids. Their mechanism of action – how they affect the brain and central nervous system – is still unclear two decades after their medical use was approved.

The UK drug statistics are mirrored in a recent analysis of drug tests in the US, which found gabapentin in over 13% of urine samples that tested positive for fentanyl. That’s about twice the number of drug tests in which prescription opioids were found.

Just because a drug is “involved” in an overdose or appears in a drug test doesn’t necessarily mean that drug caused the overdose or is a red flag for addiction. But experts say its long past time for doctors to be more careful about prescribing pregabalin, and to warn patients about potential side effects and the risk of withdrawal.

“How can there be rising deaths from pregabalin and a huge explosion of prescriptions, with all these troubles, and yet doctors are using this drug to treat anxiety?” asks Dr. Mark Horowitz, a clinical research fellow at the UK’s National Health Service.

“Doctors are selling cars without brakes,” Horowitz told The Sunday Times. “It boggles the mind when a drug is showing all these dangers to then use it on a wider variety of people.”

Gabapentinoids Still Overprescribed Despite Warnings

By Pat Anson, PNN Editor

Despite warnings that they are overprescribed for conditions they were never intended to treat, the use of gabapentinoids continues to grow in the United States.

Pregabalin (Lyrica) and gabapentin (Neurontin) are both gabapentinoids, a class of nerve medication initially developed to treat epileptic seizures. Sales of Lyrica and Neurontin tripled a decade ago, when they were touted as safer alternatives to opioids and prescribed off-label for a variety of pain conditions.

In 2018, Michael Johansen, MD, a researcher and family medicine physician, was one of the first to warn that gabapentinoids were being overprescribed, despite little of evidence of their safety and efficacy for pain conditions. Johansen was particularly concerned the drugs were being given to older adults who were long-time users of opioids and benzodiazepines, a class of anti-anxiety medication.

Not much has changed, according to a new research study by Johansen. Using data from a large national survey, Johansen found that 4.7% of U.S. adults were prescribed a gabapentinoid in 2021, up from 4% in 2015 – a statistically significant increase of 17.5% in six years. The growth was primarily driven by gabapentin, as there was little change in pregabalin’s use.

As Johansen found in his earlier study, gabapetinoid use was much more likely in patients who were co-prescribed opioids, muscle relaxants, benzodiazepines or anti-depressants for chronic pain or mental health conditions. The likelihood of a patient being prescribed a gabapentinoid also rises sharply after age 50.

“Gabapentinoids continue to be commonly used in conjunction with other sedating medications, which is concerning in light of the US Food and Drug Administration’s 2019 warning about co-prescribing of gabapentinoids with other central nervous system depressants,” Johansen reported in the Annals of Family Medicine. “Gabapentinoids are likely used for an array of conditions, with the majority being off-label uses for chronic pain with minimal evidence supporting use.”

Despite those warnings, gabapentinoids — gabapentin in particular — are still being promoted as a treatment for all sorts of things, from dental pain to alcoholism to improving your sex life. Gabapentin has been pitched for so many different conditions that a drug company executive infamously called it “snake oil.”

Gabapentin is FDA-approved for epilepsy and neuropathic pain caused by shingles, but is often prescribed off-label for depression, ADHD, migraine, fibromyalgia, bipolar disorder and postoperative pain.  Pregabalin is approved for diabetic nerve pain, fibromyalgia, post-herpetic neuralgia caused by shingles and spinal cord injuries, but is also prescribed off-label for other types of pain.

Many patients report side-effects from gabapentinoids, such as weight gain, blurred vision, dizziness, sedation and cognitive issues. There are also an increasing number of reports that the drugs are being abused and sold on the street to boost the potency of illicit drugs.

“Reports of gabapentinoid abuse alone, and with opioids, have emerged and there are serious consequences of this co-use, including respiratory depression and increased risk of opioid overdose death,” Douglas Throckmorton, MD, a top FDA official said when the agency released  its 2019 warning.  

A 2019 study found little evidence that gabapentinoids should be used off-label to treat pain and said their effectiveness was often exaggerated by prescribing guidelines. The CDC’s 2016 opioid guideline recommended gabapentin and pregabalin dozens of times as alternatives to opioids, without saying a word about their abuse or side effects.

The CDC’s 2022 revised opioid guideline takes a more cautious approach, saying gabapentin and pregabalin can have “small to moderate improvements” on pain, but were associated with a moderate risk of adverse events. Evidence on their long-term use was also lacking, according to the CDC.  

Gabapentin Won’t Cure the Opioid Crisis

By Pat Anson, PNN Editor

The risk of prescribing gabapentin (Neurontin) off-label for pain management may finally be sinking into the medical community. The latest sign is an op/ed published in JAMA Internal Medicine, which warns that gabapentin is often ineffective for pain, may raise the risk of overdose, and “will not cure the opioid crisis”    

Gabapentin is a non-opioid medication that was originally developed as an anticonvulsant to treat epileptic seizures. In recent years, gabapentin prescribing has grown 5-fold, with a growing number of physicians prescribing it “off-label” for both acute and chronic pain. Some do it as an alternative to opioids, while others prescribe it in conjunction with opioids.

“Gabapentin is often thought of as a safe alternative for pain management and may be initially enticing as a nonopioid medication, though the evidence for its efficacy in pain control is limited,” wrote lead author Raegan Durant, MD, a Professor at University of Alabama at Birmingham School of Medicine and Associate Editor at JAMA.

“With more restrictive opioid prescribing guidelines, physicians may be struggling to treat pain effectively and more frequently turning to gabapentin as a nonopioid option. However, avoidance of opioids at the expense of either more frequent use of gabapentin or concurrent gabapentin and opioids simply exposes patients to similar risks for harm often without improving the likelihood of actual pain relief.”

The warning from Durant and JAMA Associate Editor Audrey Han, MD, stems from a recent study about the “alarming upward trajectory” of gabapentin being co-prescribed with opioids.  From 2006 to 2018, overlapping prescriptions for the two medications rose by 344 percent, with many of the prescriptions being written by pain specialists.

Gabapentin is only approved by the Food and Drug Administration to treat partial seizures, nerve pain from shingles and restless leg syndrome, but is also widely prescribed off-label for fibromyalgia, neuropathy, migraine and other pain conditions – despite little evidence supporting its use.  

In addition to poor pain relief, many patients who take gabapentin report side effects such as dizziness, confusion, drowsiness, mood swings and weight gain. A 2019 study linked gabapentin to a growing number of attempted suicides.

Gabapentin may cause euphoria, feelings of intoxication, and enhance the effects of opioids and other drugs. The FDA has warned that gabapentin may cause serious breathing problems and respiratory depression, especially in older adults. A recent study found gabapentin raises the risk of delirium in seniors recovering from surgery.

Gabapentin and Pregabalin Only ‘Modestly Effective’ for Pain

By Pat Anson, PNN Editor

A new review of clinical studies on the use of gabapentin (Neurontin) and pregabalin (Lyrica) in pain management found the drugs are only “modestly effective” and could be risky for some pain patients.

Gabapentin and pregabalin belong to a class of nerve medication called gabapentinoids, which were originally developed as anticonvulsants to treat epileptic seizures. In recent years, however, they have been increasingly prescribed off-label as an alternative to opioids in managing pain. About one in five U.S. adults with chronic pain are prescribed a gabapentinoid.  

"Treating pain has been problematic for a long time, and we're still dealing with the fallout from opioid overuse," says lead author Craig Williams, PharmD, a clinical professor at Oregon State University College of Pharmacy. "Gabapentinoids are modestly effective for certain patients; they are rarely extremely effective, and they are not effective at all for some patients because the mechanisms of the pain don't match up with the mechanisms of the drug.

"Doctors who prescribe gabapentinoids for pain should do so with their eyes wide open and be prepared to stop them if they are ineffective or cause too many side effects."

The study findings, published in the journal Drugs, found that many of the clinical trials for gabapentin and pregabalin were of short duration, had a small number of participants, and performed only slightly better than placebos in reducing pain. Many patients who take the medications also report side effects such as dizziness, confusion, drowsiness, mood swings and weight gain.

"Treating pain is about making patients more functional so they can live their lives better, and if they have to deal with adverse effects for a little pain relief, their lives may not be improving," said Williams.

Pregabalin has been approved by the Food and Drug Administration for four pain conditions: post-herpetic neuralgia (shingles), diabetic peripheral neuropathy, spinal cord injury, and fibromyalgia. Gabapentin has only been approved by the FDA for post-herpetic neuralgia.

Despite the limits on their uses, many doctors legally prescribe the drugs “off-label” for pain conditions such as migraines, back pain, post-operative pain and even dental pain. Gabapentin was once derisively referred to as “snake oil” by a pharmaceutical executive because it is so widely prescribed for so many different pain conditions, despite weak evidence.

"In addition, we found that the trials used by the FDA to approve gabepentinoids for pain indications had a couple of key structural weaknesses," Williams said. "The trials tended to be short, typically lasting one to three months, and the trials typically excluded the simultaneous use of other medications that affect the central nervous system. That's important because patients taking gabepentinoids are rarely taking them exclusively; they're often prescribed in conjunction with opioids, muscle relaxants or other epilepsy drugs."

Gabapentin can cause euphoria and feelings of intoxication, and make the effect of opioids and other drugs seem stronger. A 2019 study linked gabapentin to a growing number of attempted suicides.

That same year, the FDA warned that gabapentin and pregabalin may cause serious breathing problems and respiratory depression, especially in older adults. A recent study found that gabapentin raises the risk of delirium in older adults recovering from surgery.

Gabapentin Raises Risk of Delirium in Older Surgery Patients

By Pat Anson, PNN Editor

It’s become trendy in recent years for U.S. hospitals to use gabapentin (Neurontin) as a “safer” alternative to opioids for post-operative pain.  But a large new study has found that gabapentin increases the risk of delirium and other adverse health effects in older patients recovering from surgery.

The study, published in JAMA Internal Medicine, looked at nearly a million patients over the age of 65 who had major surgical procedures, including cardiac, orthopedic and gastrointestinal surgeries. About 12% of the patients received gabapentin and other analgesics for perioperative pain management between the day of surgery and two days after surgery.

Researchers found that gabapentin “modestly increased” the risk of delirium, a mental state in which a person becomes confused, disoriented and unable to think or remember clearly. Patients who received gabapentin were also more likely to be prescribed antidepressants and other anti-psychotic drugs, and to develop pneumonia.

“Considering the increasing number of major surgeries performed in older adults, and the negative consequences of perioperative delirium, our findings raise concern about an increasingly adopted clinical practice that involves routine use of gabapentin as part of multimodal analgesia,” wrote lead author Dae Hyun Kim, MD, a geriatrician and epidemiologist at Brigham and Women's Hospital and Assistant Professor of Medicine at Harvard Medical School.

“On the basis of these findings and those of meta-analyses of RCTs (randomized controlled trials) showing a weak opioid-sparing effect of gabapentin, clinicians should reconsider routine use of gabapentin for perioperative pain management among older adults and individualize the treatment decision after assessing the risk of immediate harms vs opioid-sparing benefits of perioperative gabapentin use.”

‘Windfall Medication’

Although gabapentin is an anti-convulsant that was originally developed to treat epilepsy, it is increasingly prescribed “off-label” to treat various types of pain. In 2016, the American Pain Society recommended that gabapentin be used “around the clock” for post-operative pain because it lowered pain scores and reduced the use of opioids. But studies later found the drug was ineffective for post-operative pain and actually increased the risk of an overdose.

An editorial published in JAMA Internal Medicine said the new study demonstrates that the risks of gabapentin outweigh its potential benefits in older patients.

“These results are consistent with what is now a growing body of literature suggesting that gabapentin may not be the windfall medication for perioperative pain management that surgeons hoped it might be for decreasing opioid use. The adverse events reported in this study (delirium, antipsychotic use, and pneumonia) add to similar findings that gabapentin, especially when used concomitantly with opioids, increases the risk of postoperative sedation and dizziness,” wrote lead author Zachary Marcum, PharmD, University of Washington School of Pharmacy.  

“As the use of gabapentin continues to rise, it is critically important clinicians understand its risks, especially for older adults. Poorly controlled postoperative pain is associated with several complications, including cognitive impairment, delirium, depression, decreased mobility, and longer recovery.”

It’s a common misconception that patients often become addicted to opioids after surgery. A 2016 Canadian study found that long term opioid use after surgery is rare, with only 0.4% of older adults still taking opioids a year after major elective surgery. A 2018 study at Harvard Medical School had similar findings. Only 0.6% of patients who were prescribed opioids for post-operative pain were later diagnosed with opioid dependence, abuse or a non-fatal overdose.

Should Gabapentin Be Used for Dental Pain?

By Pat Anson, PNN Editor

Since it was first approved as an anti-seizure medication in the 1990’s, gabapentin (Neurontin) has become one of the most widely studied and prescribed drugs in world.  Although gabapentin is only approved by the FDA for epilepsy and postherpetic neuralgia (shingles), it is widely prescribed off-label for fibromyalgia, neuropathy and many other types of pain.

Hundreds of clinical trials have been conducted to find new uses for gabapentin -- for everything from asthma and obesity to alcoholism and improving your sex life. Gabapentin has been pitched for so many different conditions that a drug company executive infamously called it “snake oil.”

Now gabapentin is being touted as a “promising alternative” to opioids for dental pain. In a new study at the University of Rochester Medical Center’s Eastman Institute for Oral Health (EIOH), researchers found that gabapentin, when combined with ibuprofen or acetaminophen, was more effective than opioids in relieving pain after tooth extractions.  

“We hypothesized that using a combination of the non-opioid pain medications and adding gabapentin to the mix for pain would be an effective strategy to minimize or eliminate opioids for dental pain,” said Yanfang Ren, DDS, a dentistry professor at EIOH.   

Ren and his colleagues treated over 7,000 patients at an urgent dental care clinic with different combinations of opioids, ibuprofen, acetaminophen and gabapentin after tooth extractions. The “failure rates” of the medications were determined by how often patients returned to the clinic for additional pain relief.

The study findings, published in JAMA Network Open, found that non-opioid medications, including those with gabapentin, had failure rates significantly lower than opioids.      

Dental Pain Failure Rates

• 0.9% Acetaminophen/ibuprofen

• 3.4% Gabapentin/acetaminophen

• 5.3% Gabapentin/ibuprofen

• 9.2% Codeine/acetaminophen

• 19.4% Hydrocodone/acetaminophen

• 31.3% Other opioid combinations

Providers at the dental clinic have already put their findings into practice by sharply reducing the use of opioids. Prior to that, about 1,800 patients at the clinic were treated each year with opioids. Researchers estimate the reduced opioid prescribing may have prevented 105 of those patients from developing a problem with “persistent opioid use.”

“This study represents continued efforts by our team and other dentists to minimize the use of opioids for dental pain,” said Eli Eliav, DMD, the director of EIOH. “Additional studies, preferably randomized controlled clinical trials, are needed to confirm the safety and effectiveness of this approach. It is our duty to continuously seek safe and effective treatment for our patients in pain.”

Gabapentin has issues of its own. Patients prescribed gabapentin often complain of mood swings, depression, dizziness, fatigue and drowsiness, and a 2019 review found little evidence gabapentin should be used off-label to treat pain. There are also many reports that gabapentin is being abused and sold on the streets because it can heighten the effects of other drugs.
