Pataday Eye Drops 2.5ml, containing Olopatadine 0.2% w/v, is an antihistamine medication designed to relieve symptoms of seasonal allergic conjunctivitis. This eye condition, an allergic inflammatory response of the eye, can cause itching, redness, and swelling, often triggered by allergens such as pollen, dust, and animal dander.

Always follow your doctor's instructions carefully when using Pataday Eye Drops 2.5ml. For best results in treating allergic conditions, use it regularly at the specific time intervals your doctor advises. Do not stop using the eye drops early, even if your symptoms improve, to ensure the full course of treatment is completed. Some temporary side effects like a burning sensation, mild pain, or irritation in the eyes may occur, but these usually subside.
