Timolol/dorzolamide drops - ophthalmic
Timolol/dorzolamide drops - ophthalmic
This product contains two drugs 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, and dorzolamide belongs to a class of drugs known as carbonic anhydrase inhibitors.
Read the Patient Information Leaflet provided by your pharmacist before you start using timolol/dorzolamide and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.
This medication is for use in the eye(s), usually one drop in the affected eye(s) 2 times a day, or as directed by your doctor.
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.
Some products contain a preservative that may be absorbed by contact lenses. If you are using a product with a preservative and you wear contact lenses, remove the lenses before using the eye drops. Wait at least 15 minutes before putting in 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 in your eye. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. Try not to blink and do not rub your eye. This will prevent the medication from draining out. Repeat these steps for your other eye if so directed.
Do not rinse the dropper. Replace the dropper cap after each use.
If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 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 times 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.
Temporary blurred vision, temporary burning/stinging/itching/redness of the eye, watery eyes, dry eyes, feeling as if something is in the eye, sensitivity of eyes to light, strange taste in the mouth, or headache may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
