This medication should never be frozen. If this medication discolors or turns brown, it should be discarded--a color change indicates a loss of potency. USES Timolol (ophthalmic) is used to reduce pressure in the eye caused by glaucoma or other eye conditions. This medication belongs to a group of drugs known as beta blockers. When applied to the eye, timolol reduces pressure within the eye by decreasing eye fluid (aqueous humor) production and perhaps by increasing the outflow of fluid from the eye. TREATMENT Be sure to wash your hands with soap and water before applying this medication. In order to avoid contamination of the eye drops, be careful not to touch the tube portion of the dropper or let it touch your eye, and do not wipe off or rinse the dropper after you use it. To apply the ophthalmic drops, tilt your head back and pull down your lower eyelid with one hand to make a pouch below the eye. Drop the prescribed amount of medicine into this pouch and slowly close your eyes. Try not to blink. Keep your eyes closed, and place one finger at the corner of the eye next to your nose for a minute or two, applying a slight pressure (this is done to prevent loss of medication through the duct that drains fluid from the surface of the eye into the nose and throat). Then wipe away any excess medication with a clean tissue. Since applying the medication is somewhat difficult to do, you may want to have someone else apply the ophthalmic drops for you. If you miss a dose of this medication, apply the missed dose as soon as possible, unless it is almost time for your next dose. In that case, do not apply the missed dose at all; just return to your regular dosing schedule. If the medication is used only once a day, and you do not remember missing a dose until the next day, skip the missed dose. Do not double the next dose. SIDE EFFECTS Minor. When you first apply this medication, you may have a stinging sensation your eyes. This should stop in a few minutes. Major. Be sure to tell your doctor about any side effects that are persistent or particularly bothersome. IT IS ESPECIALLY IMPORTANT TO TELL YOUR DOCTOR about itching, skin rash, hives, or irritation of the eye that lasts more than a few minutes after application. Major side effects are rare when this product is administered correctly. However, rare occurrences of anxiety, confusion, depression, dizziness, drowsiness, generalized rash, indigestion, loss of appetite, nausea, weakness, and a slight reduction of the resting heart rate have been observed in some users of this medication. If you have any of these symptoms, it is important that you contact your doctor as soon as possible. INTERACTIONS Timolol (ophthalmic) may increase the side effects of reserpine and oral beta blockers.
