Azelast contains azelastine hydrochloride, an antihistamine that works by blocking histamine, a substance that the body releases in response to allergens. This action helps alleviate symptoms such as itching, redness, and irritation. What I appreciate most about Azelast is its fast-acting formula. I noticed relief within minutes of using the drops, and the effects lasted throughout the day, allowing me to go about my routine without constantly worrying about my eyes.
