Allegra, known generically as fexofenadine, is a popular antihistamine used to treat allergy symptoms such as runny nose, sneezing, itchy or watery eyes, hives, and itching. It works by blocking the action of histamine, a substance in the body that causes allergy symptoms. However, like all medications, Allegra is not suitable for everyone and should be used with caution under certain conditions. This article will delve into the details of when you should not take Allegra, highlighting crucial information to ensure safe and effective use.
