The health minister of France, Olivier Véran, has issued a blunt warning about painkillers taken by people ill with the coronavirus: Stay away from drugs like ibuprofen and aspirin.

Take acetaminophen instead, he advised in a tweet on Saturday. So-called nonsteroidal anti-inflammatories like ibuprofen worsened symptoms of the illness caused by the coronavirus, he said.

Some patients had experienced serious adverse effects while taking Nsaids, the health ministry said in a bulletin to doctors, and Nsaids should never be used in these patients.
