Azelastine is a second-generation antihistamine used as a nasal spray or eye drop for allergic rhinitis and conjunctivitis. It blocks histamine H1 receptors, relieving sneezing, itching, and nasal congestion. It has a rapid onset of action and minimal systemic absorption. Drowsiness is uncommon but may occur.
