Treatment of seasonal allergic rhinitis (hay fever) symptoms including sneezing, runny nose, itchy/watery eyes, and nasal/sinus congestion. May also help relieve postnasal drip and throat irritation associated with allergies.
Fexofenadine blocks histamine H1 receptors to reduce allergic reactions, while pseudoephedrine constricts blood vessels in the nasal passages to reduce swelling and congestion. This dual-action approach addresses both the histamine-mediated symptoms and nasal stuffiness.
May cause drowsiness in some people (though fexofenadine is non-drowsy for most). Avoid in patients with narrow-angle glaucoma, severe hypertension, or urinary retention. Pseudoephedrine may cause insomnia, nervousness, or increased heart rate. Consult a healthcare provider before use if pregnant, breastfeeding, or taking other medications.
