How does fexofenadine treat allergy symptoms?

Stacy Wiegman, PharmD
Pharmacy Specialist

Since fexofenadine is an antihistamine, it blocks the effects of histamine, namely allergy symptoms. That means it decreases itchiness, sneezing and itchy, watery eyes, and dries up nasal passages. Antihistamines don’t cure allergies. Instead, they’re used to control the symptoms.

Fexofenadine does have the potential to cause incorrect results on allergy tests, especially skin tests. Your doctor may ask you to stop using fexofenadine before a skin test, but you can ask about other ways to reduce your allergy symptoms.
