Olopatadine — Uses, Dosage, Side Effects & Safety

Drug class: Antihistamine (H1 receptor antagonist)

Overview

Olopatadine is an antihistamine medication used primarily to relieve symptoms of allergic conjunctivitis (eye allergies) and allergic rhinitis (nasal allergies). It works by blocking the action of histamine, a substance in the body that causes allergic symptoms such as itching, redness, and swelling. Olopatadine is available as eye drops for treating itchy, red, or watery eyes due to allergies, and as a nasal spray for symptoms like sneezing and runny nose. It provides fast relief and is generally well tolerated. Most people use it once or twice daily, as directed by their healthcare provider. Key points: Olopatadine is not a steroid and does not treat infections. Always use it exactly as prescribed, and avoid touching the dropper tip to any surface to prevent contamination.
