You might have read not to take ibuprofen if you’re getting the COVID vaccine because there is a risk of harm, or maybe your healthcare provider cautioned against you taking it after you were diagnosed COVID positive because it can worsen your symptoms. This is false, but the misinformation is still circulating. Some medical professionals have even been taken in by the low-quality evidence that spread this misinformation. Medical journals initially published these risks based on theories. No research has produced results to back up the advice. Again, there is no evidence that ibuprofen increases the risk of harm if you have COVID or if you get the vaccine. Here is an article that summarizes the events that led to the presumption of harm and then to the reviews of the literature that debunked any links to harm. It also has links to all of the research analysis. Paragon Orthopedic Center wants you to know the facts. It should be noted that ibuprofen, when taken before a vaccine, can mask an allergic reaction, so for this reason you might be told to avoid taking it. Always consult your healthcare professional before taking any medication.
