Wash your hands before using the drops, tilt your head back, and apply one drop into the affected eye(s). Avoid touching the tip of the dropper to prevent contamination. For the best results, use it regularly and at the same time each day.Some common side effects of Petolo-OD Eye Drop include eye pain, eye irritation, eye discomfort, weakness, and dry mouth. These side effects usually go away on their own after a few minutes. If side effects persist or worsen, or if you experience more severe reactions like swelling, severe itching, or rash, contact your doctor immediately. To prevent side effects, avoid using more drops than prescribed and follow the instructions carefully.While using Petolo-OD Eye Drop, avoid driving or using machinery immediately after application if you experience blurred vision.
