This medication is used to treat high pressure inside the eye due to glaucoma (open angle-type) or other eye diseases (e.g., ocular hypertension). Lowering high pressure inside the eye helps to prevent blindness. This medication works by decreasing the amount of fluid within the eye. Timolol belongs to a class of drugs known as beta-blockers.
Read the Patient Information Leaflet if available from your pharmacist before you start using timolol and each time you get a refill. If you have any questions, ask your doctor or pharmacist. To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. If you are wearing contact lenses, remove them before using eye drops. Wait at least 15 minutes before replacing your contact lenses. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch as directed by your doctor, usually once in the morning or twice daily. Look downward, gently close your eyes, and place one finger at the corner of your eye (near the nose). Apply gentle pressure for 1 to 2 minutes before opening your eyes. This will prevent the medication from draining out. Try not to blink or rub your eye. If directed to use this medication in both eyes, repeat these steps for your other eye. Wait several minutes for your vision to clear before driving or operating machinery. Do not rinse the dropper. Replace the dropper cap after each use. If you are using another kind of eye medication (such as drops or ointments), wait at least 10 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. It is important to continue using this medication even if you feel well. Most people with glaucoma or high pressure in the eyes do not feel sick.
