Can Naproxen Help You Live Longer?

By Pat Anson, PNN Editor

There may be a hidden benefit to the pain reliever naproxen. The non-steroidal anti-inflammatory drug (NSAID) is primarily used to treat arthritis, muscle aches and joint pain, but might also give a boost to your life expectancy, according to the results of a preliminary study.

An international research team analyzed 12-years of health records for over 500,000 people enrolled in the UK Biobank study to see if prescription drugs taken for at least 3 months were associated with higher or lower death rates. Over 400 medications were studied, with patients who were prescribed the drugs compared to control groups that didn’t take them.

“As expected, most drugs harbor a negative effect on lifespan, probably due to the underlying negative effect of the disease the drug is intended for. Importantly, a few drugs seem to have a beneficial effect on lifespan,” wrote lead author Alejandro Ocampo, PhD, a professor at the University of Lausanne and CEO of Epiterna, a Swiss company studying ways to slow the ageing process.        

Ocampo and his colleagues identified four medications associated with lower death rates:

• Naproxen   

• Atorvastatin (a statin)

• Estradiol (female hormone replacement)

• Sildenafil (Viagra)

Statins have long been known to reduce the risk of heart attack and stroke, while estradiol lowers the risk of osteoporosis and bone fractures in post-menopausal women. Sildenafil is well known for treating erectile dysfunction, but also improves cardiovascular health and may even protect against Alzheimer's disease. It’s easy to see how those drugs might increase life expectancy.

The inclusion of naproxen is a bit of a surprise. The active ingredient in Aleve and other over-the-counter pain relievers, naproxen raises the risk of a heart attack, stroke or internal bleeding when taken in high doses or used long-term. High doses of naproxen in 250mg and 500mg tablets are available by prescription, which is what people in the study were taking.

Even at those high doses, researchers found that naproxen was associated with a 10% lower death rate when compared to people who didn’t take the drug. The protective effect was strongest for men on naproxen, who had mortality rates that were 13% lower.

The findings are preliminary, have not been peer-reviewed, and don’t establish a cause-and-effect relationship. We don’t know why or how naproxen helps people live longer, only that it’s associated with a longer lifespan.  

Interestingly, the research team found that two other pain relievers – morphine and paracetamol (acetaminophen) – are associated with shorter lifespans. Again, this may have more to do with the underlying conditions the drugs were prescribed for, rather than the medications themselves.

Ocampo says more research and clinical studies are needed to get a better understanding of the long-term harms and benefits of medication.

“The benefit on lifespan observed for several drugs in this retrospective study could only be truly determined by performing randomized controlled trials. Such studies would aim at treating a healthy aging population with a drug during a sufficiently long follow-up to be able to observe the effect on all-cause mortality,” Ocampo wrote.

If the life expectancy benefits are proven, researchers say it could result in some drugs being “repurposed” as anti-aging treatments for otherwise healthy older adults.

Study Finds Non-Opioid Pain Relievers Effective for Arthroscopic Surgery

By Pat Anson, PNN Editor

Patients recovering from minimally invasive shoulder or knee surgery do just as well with non-opioid pain relievers as those who use opioids, according to a new study at McMaster University and Hamilton Health Sciences (HHS) in Canada.

The study, published by the Journal of the American Medical Association (JAMA), looked at 193 outpatients who had arthroscopic surgeries on their knees or shoulders at three hospitals in Hamilton, Ontario.

About half received standard care with opioids for postoperative pain, while the other half received naproxen and acetaminophen for pain, as well as pantoprazole, a medication normally used to treat heartburn and acid reflux. An emergency supply of opioids was available to both groups, if needed, for additional pain relief.

After six weeks, patients in the opioid group had used an average of 72.6 mg of opioids, compared to 8.4 mg in the opioid-sparing group. Two patients in the opioid-sparing group asked for opioid medication after discharge. Researchers say there were no significant differences in pain levels, patient satisfaction or adverse events between the two groups. 

“This study clearly shows that many of these surgical patients can be treated safely without opioid medications in a select population,” said lead author Olufemi Ayeni, MD, a professor of surgery at McMaster and an orthopedic surgeon at HHS. “Furthermore, by reducing the number of opioids prescribed, we can collectively reduce the development of a reservoir of unused medications that can cause harm to many in society.” 

Over the past decade, the number of arthroscopic surgeries has soared in North America. About one million arthroscopies are performed annually in the United States and 100,000 in Canada. Several studies, however, have that found arthroscopic surgeries provide only temporary relief from knee pain and do not improve function long term.

To be clear, there is no comparison between arthroscopies and highly invasive surgical procedures such as heart bypass surgery.  Arthroscopies are a type of “keyhole” surgery in which the surgeon makes a small incision and inserts a tiny camera and instruments to diagnose and repair damaged ligaments or joints. The procedure often takes less than an hour and patients are sent home the same day — so there is less need for pain medication.

A recent analysis of nearly half a million minimally invasive surgeries in the U.S. found that the number of opioid pills prescribed to patients fell by 50% since 2017. Hospitals are increasingly using acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), gabapentinoids and other non-opioids for post-operative pain.  

Most Americans are more worried about treating post-operative pain than they are about becoming addicted to opioids. A 2021 Harris poll found that nearly 8 out of 10 U.S. adults believe opioids are sometimes necessary to manage pain after surgery and 60% prefer opioids over OTC pain relievers.

Pregnant Women Raise Risk of Complications by Using OTC Pain Relievers

By Pat Anson, PNN Editor

Pregnant women who take over-the-counter pain relievers are one-and-a-half times more likely to have complications, including stillbirth and premature delivery, according to a large new study.

Researchers at the University of Aberdeen analyzed data from over 151,000 pregnancies in the UK from 1985-2015, looking for medical notes indicating the women used paracetamol (acetaminophen), aspirin or the non-steroidal anti-inflammatory drugs (NSAIDs) diclofenac, naproxen and ibuprofen — either alone or in combinations.

The findings, recently published in BMJ Open, show a significantly higher risk of a preterm delivery, neonatal death, low birth weight and other health problems in babies born to mothers who used OTC pain relievers. Neural tube defects of the brain, spine or spinal cord were 64% more likely; while hypospadias, a birth defect affecting the penis, was 27% more likely.

“Over-the-counter analgesics consumption during pregnancy was associated with a substantially higher risk for adverse perinatal health outcomes in the offspring. The use of paracetamol in combination with other non-steroidal anti-inflammatory drugs conferred the highest risk,” wrote lead author Aikaterini Zafeiri, PhD. “The increased risks of adverse neonatal outcomes associated with non-prescribed, over-the-counter, analgesics use during pregnancy indicate that healthcare guidance for pregnant women regarding analgesic use need urgent updating.”

One of the more surprising aspects of the study is how use of the five analgesics by pregnant women grew dramatically over the 30-year study period.  In 1985, only 1.8% reported using one of the pain relievers. By 2015, that had grown to 70.6% -- with most of the increase coming in the last seven years of the study.

Although it is believed to be one of the largest and most comprehensive studies of its kind, the research was limited. The duration, dose and stage of the pregnancy when analgesics were consumed were not recorded. The health of the mothers and babies later in life was also not studied.

But given the substantial increase in analgesic use during pregnancy and the higher risk of complications, researchers say more caution is needed on use of the drugs.

“The ease of access to non-prescription painkillers, in combination with availability of misinformation as well as correct information through the internet, raises safety concerns,” said Zafeiri. “It should be reinforced that paracetamol in combination with NSAIDs is associated with a higher risk and pregnant women should always consult their doctor or midwife before taking any over-the-counter drugs. We would encourage a strong reinforcement of the official advice for pregnant women.”   

Previous studies have linked prenatal use of paracetamol to autism, hyperactivity and behavioral problem in children. Despite the findings, drug regulators in the UK and US maintain that it is safe for pregnant women to use paracetamol (acetaminophen).

“Paracetamol is the first choice of painkiller if you're pregnant or breastfeeding. It's been taken by many pregnant and breastfeeding women with no harmful effects in the mother or baby,” the UK’s National Health Service (NHS) says on its website.

The Food and Drug Administration also does not caution pregnant women about using acetaminophen. The agency said in 2015 that the evidence was “too limited” to justify such a warning.  

Meanwhile, drug regulators in Australia are so concerned about recent deaths involving paracetamol that they may restrict access to the drug. Australia’s Therapeutic Goods Administration (TGA) has commissioned a report by an expert panel on the risks of paracetamol misuse.

“While paracetamol has well established safety and toxicity profiles, the wide use is paralleled by a high prevalence of accidental and deliberate paracetamol poisoning in the community, in both adults and children,” the TGA said in a statement earlier this month.

“The TGA is aware of concerns, particularly of families and healthcare professionals of affected consumers of paracetamol, regarding the number of poisonings and deliberate overdoses from paracetamol obtained from general retail outlets, and whether current access restrictions are appropriate.”

Australia currently regulates the quantity and dose of paracetamol sold over-the-counter. The independent commission will consider if stricter buying limits should be imposed. 

Over-the-Counter Pain Meds and Gabapentin Recommended for Trauma Patients

By Pat Anson, PNN Editor

Over-the-counter pain medications and gabapentin are the best line of treatment for trauma patients suffering from acute short-term pain, according to new study at a Texas hospital that minimizes the use of opioids.

Researchers at the Red Duke Trauma Institute at Memorial Hermann-Texas Medical Center in Houston assessed two different combinations of non-opioid pain relievers in over 1,500 patients being treated for acute trauma, such as bone fractures and head injuries.

The treatment protocol that was deemed superior included a combination of inexpensive over-the-counter drugs such as acetaminophen and naproxen, with the nerve medication gabapentin (Neurontin). Opioids such as tramadol and oxycodone were only prescribed for breakthrough pain.

"Narcotics are not the mainstay of therapy for acute pain," said lead author John Harvin, MD, a trauma surgeon at the hospital and an associate professor at The University of Texas Health Science Center at Houston. "The research shows us that seriously injured people with acute pain can effectively be treated with an opioid-minimizing strategy."

The study findings, published in the Journal of American College of Surgeons, showed that a first-line pain regimen that used acetaminophen, ketorolac, naproxen, gabapentin or lidocaine patches reduced the use of opioids without a significant difference in pain scores. Only 62 percent of the patients were discharged with an opioid prescription.

"We used a generic pain regimen that is affordable at discharge. The discharge medications acetaminophen and naproxen can be bought over the counter. The only drug that requires a prescription is gabapentin and an as-needed opioid, if prescribed," Harvin explained.

The use of gabapentin as a treatment for acute pain is controversial, because recent studies show it has no significant analgesic effect and is increasingly being abused. In 2019, the Food and Drug Administration warned that serious breathing problems can occur in patients who take gabapentin with opioids or other drugs that depress the central nervous system.

But the use of gabapentin and over-the-counter pain relievers is now the standard treatment protocol for trauma patients at Memorial Hermann-Texas Medical Center, and physicians there are working to adapt it for the treatment of acute burn pain.

"The best way to decrease someone's risk for long-term (opioid) use is to minimize their exposure during hospitalization and at discharge, and we now know there are excellent non-opioid medications available that effectively treat pain,” said Harvin. “We know that culture change will take time and effort, but we're excited to be learning how to best leverage opioid-minimizing drugs to improve care, and to offer a new model that can be adopted by any trauma center."

The risk of long-term opioid use after an emergency room visit is actually quite low. A 2017 study by the Mayo Clinic found that only about one percent of emergency room patients given an opioid prescription progressed to long term use.

"Our paper lays to rest the notion that emergency physicians are handing out opioids like candy," said lead author Molly Moore Jeffery, PhD, a Mayo Clinic researcher. “Most opioid prescriptions written in the emergency department are for shorter duration, written for lower daily doses and less likely to be for long-acting formulations."

The Hidden Dangers of Self-Medicating with OTC Drugs

By James Campbell, MD, Guest Columnist

The Centers for Disease Control and Prevention (CDC) recently unveiled guidelines for primary care physicians on the use of opioids for chronic pain. Not surprisingly, the guidelines urge physicians to first try non-pharmacologic and non-opioid treatments before resorting to opioid therapy.

If you’re one of the millions of Americans living with pain on a daily basis, it’s likely you’re not a stranger to over-the-counter (OTC), non-prescription pain medications such as naproxen (brand name Aleve), ibuprofen (Advil and Motrin), aspirin and acetaminophen (Tylenol).

In fact, most of my patients with chronic pain began their quest for relief with a cocktail of OTC pain relievers, muscle relaxants and even alcohol, before seeking professional help and eventually graduating to prescription treatments such as opioids, anti-depressants and anticonvulsants.

While OTC pain medications are generally safe when taken at their recommended doses, it’s all too common for patients to unknowingly put themselves at risk of a fatal accidental overdose or serious drug-drug interactions by mixing OTC pain medications or taking them in combination with prescription treatments for pain or other common health conditions.

Given the sheer magnitude of serious adverse events and fatalities associated with opioids, the hidden, yet preventable dangers of the pain medications on your pharmacy shelves are not often discussed.

Let’s take one of the most common OTC pain relievers: acetaminophen. When used as directed within the advised dosing guidelines, acetaminophen is safe and effective. However, if a person takes more than one medication that contains acetaminophen and exceeds the maximum recommended dose, they may be at risk of serious liver damage.

This happens so often that acetaminophen overdose is the leading cause of calls to poison control centers in the United States -- more than 100,000 instances per year – and are responsible for more than 56,000 emergency room visits.

In fact, in 2011, in an effort to reduce the risk of severe liver injury from acetaminophen overdose, the Food and Drug Administration (FDA) asked drug manufacturers to limit the strength of acetaminophen in prescription medications, including combination acetaminophen and opioid products, to no more than 325 mg per tablet, capsule or other dosage unit.

Then in 2014, the FDA recommended that health care professionals discontinue prescribing and dispensing prescription combination products that contain more than 325 mg of acetaminophen.

While the FDA’s efforts may help curb accidental overdose related to prescription medications that contain acetaminophen (Tylenol with codeine, for example), it does little to address the risks of OTC acetaminophen or other OTC pain medications such as ibuprofen, a type of non-steroidal anti-inflammatory drug (NSAID), which can cause gastrointestinal bleeding and injury, and cardiovascular side effects when taken on a chronic basis.

Drug Interactions

In addition to the risk of overdose, people taking multiple OTC and prescription medications for pain and other conditions are also at risk of serious drug-drug interactions. Simply put, any “drug” – whether it be a medicine, vitamin, supplement or even alcohol – that enters your body and alters your natural internal chemistry has the potential to interact or alter the intended effect or unintended side effect of other medications.

Even though most medications are accompanied by warnings about combining them with other drugs, most vitamins and supplements are not -- so, unless you’re a licensed medical professional, it’s virtually impossible to recognize the potential for drug-drug interactions.

If you’re using OTC medications, whether alone or with prescription medications, to cope with pain on a daily basis, here are three precautionary steps you can take to safeguard yourself against the risk of accidental overdose or drug-drug interactions.

1) Recognize that ALL medications, whether OTC or prescription, can cause harm if used improperly, and the fact that some medications are available without a prescription does not mean they are inherently safe. Read the labels that come with your medications. Tylenol, Advil and Vicodin are household names, so it can be easy to overlook their “generic” names (or the active ingredient in each).

For example, the generic name for Tylenol is acetaminophen, while that of Vicodin is acetaminophen hydrocodone. Without close examination of either label, a person taking Vicodin and Tylenol together could be inadvertently exceeding the recommended dosage of acetaminophen.

2) Consult a medical professional before you take more than one medication on a daily basis. If your chronic pain is being treated by a physician, be sure to tell them (even if it’s on your medical history) about any OTC or prescription medications you are currently taking. This includes vitamins and other supplements that may seem harmless, but could interact with your pain medications.

3) If you are independently treating your chronic pain, make a list of all the medications, vitamins and supplements you take on a regular basis and share them with your local pharmacist. Pharmacists can identify potential drug-drug interactions like taking acetaminophen and ibuprofen on a long-term basis, which can result in an increased risk of developing kidney problems.

The American Chronic Pain Association also recommends using the same pharmacy for all your prescriptions, so that the pharmacist can screen health information and current medications to avoid the pitfalls of overdose and drug interactions.

As a neurosurgeon with a special interest in pain for over 30 years, I’m empathetic to the daily struggle that patients face and their desperate quest for relief, seeking anything and everything that can simply make the pain stop.

For the patients who are fighting this seemingly endless battle with pain without the help of a medical professional, I hope I’ve provided some useful information and practical advice to help avoid serious risks associated with self-medicating. However, people living with moderate to severe chronic pain may benefit from a consultation with a licensed pain management specialist, who can help guide you toward steps that will help reduce your pain.

Researchers Say NSAIDs Cause Heart Damage

By Pat Anson, Editor

Researchers have known for many years that non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of heart attack and stroke. Now they may finally be learning why the pain relievers can be harmful.

In experiments on heart cells from rats and mice, scientists at the University of California, Davis, found that NSAIDs reduced the activity of cardiac cells at pharmacological levels found in humans. Their study was recently published in the Journal of Molecular and Cellular Cardiology.

“We knew these non-steroidal anti-inflammatories had negative side effects for heart disease and stroke risk, “ said lead author Aldrin Gomes, a UC Davis associate professor of Neurobiology, Physiology and Behavior. “But now we have an idea of some of the mechanisms behind it.”

NSAIDs are widely used to treat everything from fever and headache to low back pain and arthritis. They are found in so many different products -- such as ibuprofen, Advil and Motrin -- that many consumers may not be aware how often they use NSAIDs. 

Several studies have found that NSAIDs increase the risk of cardiovascular disease and other health problems, but the exact cause has been unclear.

The UC Davis researchers compared naproxen, considered the safest over-the-counter NSAID, with a more potent anti-inflammatory, the prescription drug meclofenamate sodium (MS).

They found that MS increased reactive oxygen species, impaired mitochondrial function, decreased proteasome function, and increased cardiac cell death. Naproxen did not affect proteasome function or cause heart cells to die, but it did impair mitochondrial function and increase reactive oxygen species produced in cardiac cells.

“We were surprised to see that many of the NSAIDs we tested were causing the cardiac cell to die when used for prolonged periods,” said Gomes. “Some people are taking these drugs too often, and this is a problem. These drugs are abused.”

For moderate pain, Gomes suggests rubbing an anti-inflammatory topically onto the pained area, which would not expose the entire body to the drug. Taking an antioxidant like vitamin C before ingesting a NSAID may also reduce cardiac cell death.

Last year the U.S. Food and Drug Administration ordered warning labels for all NSAIDs to be strengthened to indicate they increase the risk of a fatal heart attack or stroke. The agency said studies have shown the risk of serious side effects can occur in the first few weeks of using NSAIDs and could increase the longer people use the drugs. The revised warning does not apply to aspirin.

The FDA said people who have a history of heart disease, particularly those who recently had a heart attack or cardiac bypass surgery, are at the greatest risk. But the risk is also present for people who don't have heart problems.

“Everyone may be at risk – even people without an underlying risk for cardiovascular disease,” said Judy Racoosin, MD, deputy director of FDA’s Division of Anesthesia, Analgesia, and Addiction Products.

In a major study published recently in the European Heart Journal, a number of leading heart specialists warned that there is no "solid evidence" that NSAIDs are safe.

"When doctors issue prescriptions for NSAIDs, they must in each individual case carry out a thorough assessment of the risk of heart complications and bleeding. NSAIDs should only be sold over the counter when it comes with an adequate warning about the associated cardiovascular risks. In general, NSAIDs are not be used in patients who have or are at high-risk of cardiovascular diseases," said co-author Christian Torp-Pedersen, a professor in cardiology at Aalborg University in Denmark.

Aleve & Other Pain Relievers Reduce Fertility in Women

By Pat Anson, Editor

Health experts have warned for years about the side effects of over-the-counter pain relievers – everything from liver failure to heart disease to hearing loss.

Now researchers are saying that Aleve and some other non-steroidal anti-inflammatory drugs (NSAIDs) reduce the fertility of women so significantly they could potentially be used as an emergency form of contraception.

The results of a small study presented at the European League Against Rheumatism Annual Congress show that three NSAIDs --  naproxen, diclofenac, and etoricoxib -- inhibited ovulation in women after just a few days of treatment.

Naproxen, diclofenac, and etoricoxib are the active ingredients in several brand name drugs sold around the world, including Aleve, Voltaren, and Arcoxia, respectively. Etoricoxib is not approved for use in the United States.

Thirty nine Iraqi women of childbearing age who suffered from back pain took part in the study; receiving diclofenac (100mg once daily), naproxen (500mg twice daily), etoricoxib (90mg once daily), or a placebo.

Treatment was given for 10 days from day 10 of the onset of their menstrual cycle, with their progesterone levels and follicle diameter analyzed via blood sample and sonography.

“After just ten days of treatment we saw a significant decrease in progesterone, a hormone essential for ovulation, across all treatment groups, as well as functional cysts in one third of patients,” said study investigator Professor Sami Salman, Department of Rheumatology, University of Baghdad.

“These findings show that even short-term use of these popular, over-the-counter drugs could have a significant impact on a woman's ability to have children. This needs to be better communicated to patients with rheumatic diseases, who may take these drugs on a regular basis with little awareness of the impact.”

Of the women receiving NSAIDs, only 6.3% taking diclofenac, 25% taking naproxen, and 27.3% taking etoricoxib ovulated, compared with 100% of the control group that was not taking a pain reliever.

The dominant follicle remained unruptured in 75% of the women taking diclofenac, 25% taking naproxen and 33% of the patients receiving etoricoxib. Rupturing of the dominant follicle and the subsequent release of an oocyte (unfertilized egg), is essential for ovulation to occur.

“These findings highlight the harmful effects NSAIDs may have on fertility, and could open the door for research into a new emergency contraception with a more favorable safety profile than those currently in use,” said Salman.

NSAIDs are among the most common pain relief medicines in the world. Every day more than 30 million Americans use them to relieve pain, lower fever and reduce inflammation.
