The reason why ibuprofen is not recommended for coronavirus is because there is some preliminary data suggesting that taking anti-inflammatory drugs during a coronavirus infection could potentially worsen symptoms. These findings have come from Europe, where some young patients who were hospitalized due to coronavirus were taking these medications. While it's not clear if there is a direct cause and effect relationship, it is currently advised to avoid taking ibuprofen to reduce flu-like symptoms. Instead, acetaminophen (Tylenol) is recommended. It is better to err on the side of caution until more information is available.
