Description
Fexofenadine hydrochloride (trade name: Allegra) belongs to a second-generation antihistamine pharmaceutical drug. It is mainly used for the treatment of allergy symptoms including watery eyes, hay fever, nasal congestion, urticaria, runny nose, itching eyes/nose, sneezing, hives, and itching. It is a kind of selectively peripheral H1 blocker. Its mechanism of action in vivo is through preventing the histamine-mediated activation of the H1 receptors, thus alleviating the symptoms related to allergy. Compared to the first-generation antihistamine drug, it is less prone to penetrate the blood-brain barrier, reducing the possibility to cause side effects such as drowsiness.
Uses
This combination medication is used to temporarily relieve symptoms caused by thecommon cold, flu, or allergies. It contains 2 medications: fexofenadine andpseudoephedrine. Fexofenadine is an antihistamine that helps relieve watery eyes, itchy eyes/nose/throat, runny nose, and sneezing. Pseudoephedrine is a decongestantthat helps relieve stuffy nose and ear congestion symptoms.
This medication is not recommended for use in children under 12 years of age due to the large amount of pseudoephedrine in it.
