TIMOLOL (OPHTHALMIC)
------------------------------------------------------------------------------

BRAND NAME (Manufacturer):
     Timoptic (Merck Sharp & Dohme)
TYPE OF DRUG:
     Antiglaucoma ophthalmic solution
INGREDIENT:
     timolol
DOSAGE FORM:
     Ophthalmic drops (0.25% and 0.5%)
STORAGE:
     Timolol ophthalmic drops should be stored at room temperature in a
       tightly closed container.  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

     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, it may sting your eyes.  This
should stop in a few minutes.

     Major.

     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
used correctly.  However, rare occurrences of anxiety, bronchospasm,
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 drug.  If you have any of
these symptoms, contact your doctor.

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, especially reserpine or oral
beta blockers.

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, 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.
     * Be sure to tell your doctor if you are pregnant.  Small amounts of
timolol may be absorbed into the bloodstream, and its safety in human
pregnancy has not been established.  Birth defects have been observed in the
fetuses of animals that were given large oral doses of this type of drug
during pregnancy.  Also, tell your doctor if you are breast-feeding an infant.
If this drug reaches the bloodstream and passes into the breast milk, it can
cause a slowed heart rate in the nursing infant.
