AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Allegra-D 24 Hour is a fixed-dose combination oral tablet combining fexofenadine hydrochloride (a non-sedating antihistamine) and pseudoephedrine hydrochloride (a decongestant) in extended-release formulation. It treats symptoms of hay fever and upper respiratory allergies including runny nose, sneezing, itchy/watery eyes, nasal congestion, and sinus pressure. The fexofenadine blocks histamine receptors to reduce allergic symptoms while pseudoephedrine constricts nasal blood vessels to relieve congestion.
