Update: Since the time of writing, the WHO has updated its advice on ibuprofen: "Based on currently available information, WHO does not recommend against the use of ibuprofen."

Ibuprofen is commonly used to treat pain, inflammation and fever. While the latter is one of the most common symptoms of coronavirus, patients have been warned not to use the painkiller for the time being, as it is suspected that it might aggravate the disease. 

WHO: Take paracetamol, not ibuprofen

The World Health Organisation (WHO) advised people who suspect they might have coronavirus not to take the drug ibuprofen without first consulting with their doctor. “We advise you to take acetminophen [paracetamol] in suspected cases, not ibuprofen,” said WHO spokesperson Christian Lindmeier

Last weekend saw the appearance of several warnings that ibuprofen could accelerate COVID-19 infections. The French Health Ministry caused a particular sensation when it published a tweet advising people not to take anti-inflammatory drugs like ibuprofen. 

Paracetamol less likely to cause side effects

There is currently no published scientific evidence showing definitively that coronavirus is made worse by ibuprofen, Lindmeier said, but the situation is still being monitored by experts. 

Generally, however, paracetmol is the “preferred” medicine since it is just as effective at tackling fevers and headaches but less likely to cause side effects. If taken for a prolonged period of time, non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can cause stomach irritation and stress on the kidneys.
