Allegra 120mg contains fexofenadine hydrochloride, a second-generation antihistamine specifically designed to provide powerful allergy relief without the drowsiness associated with older antihistamines. Each tablet provides up to 24 hours of relief from allergic rhinitis symptoms.
Fexofenadine is clinically proven to begin working within one hour of ingestion. Unlike first-generation antihistamines such as diphenhydramine, fexofenadine does not readily cross the blood-brain barrier, which means it is far less likely to cause sedation or impair cognitive function.

Directions: Take one 120mg tablet once daily before a meal with water.
