Felbinac is a nonsteroidal anti-inflammatory drug (NSAID) used topically in the form of a gel or aerosol foam to alleviate pain and inflammation resulting from injuries like sprains or bruises. Occasionally, it can lead to localized skin irritation. Since a portion of the drug is absorbed into the bloodstream, individuals who have had negative responses to oral NSAIDs, such as exacerbated asthma symptoms, should avoid using Felbinac.
