How to Use timolol
This medicine is only for use in the eye. Do not take by mouth. Follow the directions on the prescription label. If you are using a unit dose container, use immediately after opening and throw away right after use. Wash hands before and after use. Tilt your head back slightly and pull your lower eyelid down with your index finger to form a pouch. Try not to touch the tip of the dropper to your eye, fingertips, or any other surface. Squeeze the prescribed number of drops into the pouch. Close the eye for a few moments to spread the drops and apply gentle finger pressure to the inner corner of the eye for 1 to 2 minutes. Use your doses at regular intervals. Do not use your medicine more often than directed. Do not stop using except on the advice of your doctor or health care professional.
