Description
Olopatadine is an antihistamine used in the form of eye drops to treat allergic conjunctivitis. It works by blocking histamine receptors, which trigger allergic reactions in the eyes. This helps relieve symptoms such as itching, redness, watering, and swelling. Relief is usually fast-acting and targeted, making it effective for both seasonal and chronic allergic eye conditions.
