With the number of coronavirus cases growing to nearly 200,000 worldwide, so is confusion about which over-the-counter pain reliever should be used to treat its symptoms. Some health experts say acetaminophen – known as paracetamol outside the U.S. – is better than ibuprofen, aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs).

"We recommend paracetamol, not ibuprofen for self-medicating," Christian Lindmeier, a spokesman for the World Health Organization said today.

At issue is whether ibuprofen and other NSAIDs interfere with the body’s immune system and make coronavirus symptoms worse. The debate was kicked off Saturday by a tweet from France’s Health Minister.

“Taking anti-inflammatory drugs (ibuprofen, cortisone, ...) could be an aggravating factor of the infection. If you have a fever, take paracetamol,” said Dr. Olivier Véran, a neurologist.

That same day, the French government reported "grave adverse effects" linked to the use of NSAIDs in coronavirus patients and released new guidelines saying “the treatment of a fever or of pain linked to COVID-19 or to any other respiratory viral disease should be paracetamol.”

But the UK’s Royal Pharmaceutical Society (RPS) disputed whether there was enough evidence to make such a recommendation.

“There is not currently enough information on ibuprofen use and COVID-19 to advise people to stop using NSAIDs. There is currently no published scientific evidence that ibuprofen increases the risk of catching COVID-19 or makes the illness worse. In addition, there is also no conclusive evidence that taking ibuprofen is harmful for other respiratory infections,” the RPS said in a statement.

The Medical University of Vienna also chimed in, calling reports that it had found a connection between ibuprofen use and worse coronavirus symptoms "fake news."

But other experts agreed that NSAIDs can weaken the immune system.

“Despite all of their beneficial effects, it has long been known that anti-inflammatories can have a depressive effect on parts of our immune systems,” Dr. Amir Khan of Britain’s National Health Service said in Al Jazeera. “If we take medicines that dampen this immune response, such as ibuprofen, this can lead to us not fighting off the infection as effectively, potentially leading to a longer illness with a higher risk of complications.

“Paracetamol is not an anti-inflammatory medication and can be used to effectively treat fever as well as mild to moderate pain and can, therefore, be used safely to help treat the fever associated with the coronavirus.”

The NHS also updated its recommendations, cautioning that while there is no strong evidence that ibuprofen makes coronavirus worse, “until we have more information, take paracetamol to treat the symptoms of coronavirus.”

‘Don’t Give Her Ibuprofen!’

The New York Post reported that a 4-year old British girl suffering coronavirus symptoms had difficulty breathing and took a turn for the worse after taking ibuprofen. Amelia Collins had a cough, fever and other flu-like symptoms.

“To those of you that have children please read. If your child has symptoms of corona virus, DO NOT give them ibuprofen,” Amelia’s father posted on Facebook. “Within an hour of giving her [ibuprofen] she dropped dramatically. She was panting while trying to breathe, her heart rate was very rapid, she couldn’t keep her eyes open, couldn’t lift her head up, her body was shaking, she started being sick on herself and her temperature had risen.”

Amelia’s parents called for an ambulance. Fortunately, paramedics were able reduce her fever without taking her to a hospital.

“Now she’s back on [acetaminophen] she’s back to just being her poorly self. The paramedics only told us while here that were not to give her ibuprofen!” the father said.

In 2015, the U.S. Food and Drug Administration warned that “everyone may be at risk” and ordered new warning labels for ibuprofen and other NSAIDs to indicate they increase the risk of a fatal heart attack or stroke.

But acetaminophen also has issues. The pain reliever has long been associated with liver injury and allergic reactions such as skin rash. Acetaminophen is the active ingredient in hundreds of over-the-counter pain relievers and cough, cold and flu medicines – and many consumers have no idea how much acetaminophen they’re taking.

Over 50,000 emergency room visits each year in the U.S. are blamed on acetaminophen overdoses, including 25,000 hospitalizations and hundreds of deaths.
