France’s health ministry has suggested that popular anti-inflammatory painkillers such as ibuprofen could worsen the effects of the coronavirus, raising questions over which over-the-counter drugs people should be taking to treat the symptoms of the disease.
Health Minister Olivier Veran, who has also worked as a neurologist, tweeted on Saturday that “taking anti-inflammatory drugs (ibuprofen, cortisone…) could be an aggravating factor of the infection. If you have a fever, take paracetamol. If you are already on anti-inflammatory drugs or in doubt, ask your doctor for advice.”
His suggestion was criticized by some health experts, who cited the lack of publicly available evidence suggesting a link between ibuprofen and adverse effects of the coronavirus.
Veran’s recommendation came on the same day that the French government reported that “grave adverse effects” linked to the use of non-steroidal anti-inflammatory drugs (NSAID) — the family of drugs that includes ibuprofen — have “been identified with patients affected by COVID-19, in potential or confirmed cases.”
“We repeat that the treatment of a fever or of pain linked to COVID-19 or to any other respiratory viral disease should be paracetamol,” the ministry’s new guidelines added. Paracetamol is typically known in the US as acetaminophen.
Veran’s tweet was widely shared, particularly in France, and the advice has raised questions over the impact of ibuprofen to treat the virus. CNN has contacted the French health ministry for comment.
“Deeply concerned about this bold statement,” Muge Cevik, a researcher at the University of St Andrews Infection and Global Health Division, said on Twitter. “There’s no scientific evidence I am aware of that ibuprofen [causes worse] outcomes in #COVID19.”
But other experts suggested that Veran’s advice is in line with some countries’ general guidance on anti-inflammatory painkillers such as ibuprofen, even if their specific connection to the coronavirus is not clear.
“There is a good reason to avoid ibuprofen as it may exacerbate acute kidney injury brought on by any severe illness, including severe COVID-19 disease. There isn’t yet any widely accepted additional reason to avoid it for COVID-19,” Rupert Beale, a group leader in Cell Biology of Infection at the UK’s Francis Crick Institute, told the UK’s Science Media Centre.
Paracetamol ‘generally preferred’ over ibuprofen
Ibuprofen, an NSAID, is often used to treat fever, one of the most common symptoms of the virus.
“Most deaths from COVID-19 have been among older people and those with underlying health conditions such as cardiovascular disease. We already know that NSAIDs should be prescribed with caution for people who have underlying health conditions,” Charlotte Warren-Gash, Associate Professor of Epidemiology, London School of Hygiene and Tropical Medicine, said.
France already has stricter rules than many other countries regarding the sale of painkillers, and moved products like paracetamol and ibuprofen behind the counter earlier this year.
The UK’s National Institute for Health and Care Excellence, meanwhile, recommends prescribing the lowest dose of ibuprofen for the shortest duration to patients with underlying conditions, to prevent side effects including cardiovascular or kidney problems. The NHS advises using ibuprofen over paracetamol for inflammatory problems like arthritis, but warns against taking it for long periods.
“For COVID-19, research is needed into the effects of specific NSAIDs among people with different underlying health conditions, which takes into account the severity of infection,” Warren-Gash added.
“In the meantime, for treating symptoms such as fever and sore throat, it seems sensible to stick to paracetamol as first choice.”
Tom Wingfield, a lecturer and consultant physician at the Liverpool School of Tropical Medicine, also advised that paracetamol “would generally be preferred” over ibuprofen in most cases.
He said paracetamol is less likely to cause side effects than ibuprofen, which has been found to cause stomach and kidney irritation in some people.
“It is not clear from the French Minister’s comments whether the advice given is generic ‘good practice’ guidance or specifically related to data emerging from cases of COVID-19, but this might become clear in due course,” he added.
The coronavirus pandemic has led to sweeping restrictions in France and across Europe. The country announced on Saturday it is closing restaurants, cafes, cinemas and clubs in an effort to increase social distancing.
