Do not allow the dropper to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
Do not use any other eye medication unless your doctor has prescribed it for you. If you use another eye medication, use it at least 10 minutes before or after using timolol ophthalmic. Do not use the medications at the same time.
