Allegra Allergy 24H, 180 mg , 24 Gelcaps

Allegra Allergy 24H is an over-the-counter antihistamine tablet designed to provide 24-hour relief from seasonal allergy symptoms like sneezing, runny nose, and itchy, watery eyes. Its active ingredient is fexofenadine hydrochloride at a 180 mg dose per tablet, which the manufacturer notes is a non-drowsy formula that does not cross the blood-brain barrier, aiming to avoid drowsiness while offering fast-acting relief reported to start within one hour.

This product is positioned as the #1 allergist-recommended non-drowsy allergy brand among OTC oral antihistamines, according to the manufacturer. It is formulated for both indoor and outdoor allergies and comes in a 24-count package of gelcaps. The manufacturer provides detailed explanations of inactive ingredients, such as microcrystalline cellulose for uniform distribution and croscarmellose sodium to aid breakdown, though these are common excipients. Practical notes include directions for adults and children 12 years and older to take one tablet daily with water, with warnings to consult a doctor for those with kidney disease or who are pregnant or breastfeeding.
