- Timoptic (Merck Sharp & Dohme)
-
- TYPE OF DRUG
-
- Antiglaucoma ophthalmic solution
-
- INGREDIENT
-
- timolol
-

- Ophthalmic drops (0.25% and 0.5%)
-
- STORAGE
-
- Timolol ophthalmic drops should be stored at room temperature in a

- 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.
- Before starting to take timolol (ophthalmic), BE SURE TO TELL YOUR DOCTOR
- about any medications you are currently taking.
-
- WARNINGS
-
- * Tell your doctor about unusual or allergic reactions you have had to
- any medications, especially to timolol or to any other beta blockers
- (acebutolol, atenolol, betaxolol, carteolol, esmolol, labetalol, metoprolol,
- nadolol, penbutolol, pindolol, or propranolol).
- * Tell your doctor if you now have or if you have ever had asthma,
- diabetes mellitus, heart disease, or myasthenia gravis.
- * Your doctor should check your eye pressure regularly to be sure the
- glaucoma is under control.
- * Tell your doctor if you are pregnant. Small amounts of timolol may be
- absorbed into the bloodstream, and its safety in pregnancy has not been
- established. Birth defects have been observed in the fetuses of animals that
- were given large doses of this drug during pregnancy. Also, tell your doctor
- if you are breast-feeding. If this drug reaches the bloodstream and passes
- into the breast milk, it can cause a slowed heart rate in the nursing infant.
