What this medicine is used for
The name of your medicine is APO-Dorzolamide/Timolol eye drops. It contains the active
ingredients dorzolamide (22.3 mg of dorzolamide hydrochloride) and timolol (6.8 mg
of timolol maleate).
It is used to treat lower raised pressure in the eye and to treat glaucoma. Glaucoma
is a condition in which the pressure of fluid in the eye may be high. However, some
people with glaucoma may have normal eye pressure. Also, some people with raised eye
pressure may not have glaucoma.
Glaucoma is usually caused by a build-up of the fluid which flows through the eye.
This build up occurs because the fluid drains out of your eye more slowly than it
is being pumped in. Since new fluid continues to enter the eye, joining the fluid
already there, the pressure continues to rise. This raised pressure may damage the
back of the eye resulting in gradual loss of sight. Damage can progress so slowly
that the person is not aware of this gradual loss of sight.
Sometimes even normal eye pressure is associated with damage to the back of the eye.
There are usually no symptoms of glaucoma. The only way of knowing that you have glaucoma
is to have your eye pressure, optic nerve and visual field checked by an eye specialist
or optometrist. If glaucoma is not treated it can lead to serious problems. You may
have no symptoms but eventually glaucoma can lead to total blindness. In fact, untreated
glaucoma is one of the most common causes of blindness.
Although dorzolamide/timolol helps control your glaucoma it does not cure it.
For more information about glaucoma, contact Glaucoma Australia Inc., PO Box 420,
Crows Nest 1585, telephone 02 9906 6640.
Ask your doctor if you have any questions about why this medicine has been prescribed
for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Dorzolamide/timolol contains two active ingredients, dorzolamide (as hydrochloride)
and timolol (as maleate). Both of these active ingredients lower pressure in the eye
by reducing the production of fluid, but they do this in different ways.
Dorzolamide (as hydrochloride) belongs to a family of medicines called carbonic anhydrase
Timolol (as maleate) belongs to a family of medicines called beta-blockers.
There is no evidence that this medicine is addictive.
Use in children
This medicine should not be used in children.
The safety and effectiveness of dorzolamide in children have not been established.

1. Wash your hands well with soap and water.
2. Unscrew the cap and break it off from the seal.
3. Place the cap upside down on a flat surface. Do not touch the inside of the cap. This
will help keep the inside of the cap clean and keep germs out of the eye drops.
4. Use your finger to gently pull down the lower eyelid of the affected eye.
5. Tilt your head back and look up.

8. Close your eye and keep it closed. Do not blink or rub your eye.
9. While your eye is still closed, place your index finger against the inside corner
of your eye and press against your nose for about two minutes. This will help to stop
the medicine from draining through the tear duct to the nose and throat, from where
it can be absorbed into other parts of your body. Ask your doctor or pharmacist for
more specific instructions on this technique.
10. Screw the cap back on the bottle, sealing it tightly. Do not over tighten the cap.
11. Wash your hands again with soap and water to remove any residue.
Wait at least 15 minutes before replacing your contact lenses.
Be careful not to touch the dropper tip against your eye, eyelid or anything else
to avoid contaminating the eye drops.
Contaminated eye drops may give you an eye infection.
You may feel a slight burning sensation in the eye shortly after using the eye drops.
If this persists, or is very uncomfortable, contact your doctor or pharmacist.
When to take it
Use dorzolamide/timolol every day, at about the same time each day, unless your doctor
tells you otherwise.

pressure. It will also help you remember when to use the eye drops.

eye drops in your eye(s).
It does not matter if you take it before, with or after food.

for as long as your doctor prescribes.
Make sure you have enough of this medicine to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the missed dose and take your next
dose at the usual time. Otherwise, take it as soon as you remember and then go back
to taking your medicine as you would normally.
