Dorzolamide / Timolol contains two medicines: dorzolamide and timolol.
These medicines lower the pressure in the eye in different ways.
Dorzolamide / Timolol is prescribed to lower raised pressure in the eye in the treatment of glaucoma when beta-blocker eye drop medicine used alone is not adequate.

Also tell your doctor:
When Dorzolamide / Timolol is instilled into the eye it may affect the entire body.
Children and adolescents
There is limited experience with Dorzolamide / Timolol in infants and children.

Other medicines and Dorzolamide / Timolol
Dorzolamide / Timolol can affect or be affected by other medicines you are using, including other eye drops for the treatment of glaucoma. Tell your doctor if you are using or intend to use medicines to lower blood pressure, heart medicine or medicines to treat diabetes. Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
This is particularly important if you are:
Pregnancy, breast-feeding and fertility
Ask your doctor or pharmacist for advice before taking any medicine.
Use in pregnancy
Do not use Dorzolamide / Timolol if you are pregnant unless your doctor considers it necessary.
Use in breast-feeding
Do not use Dorzolamide / Timolol if you are breast-feeding. Timolol may get into your milk. Ask your doctor for advice before taking any medicine during breast-feeding.
Driving and using machines
No studies on the effects on the ability to drive or use machines have been performed. There are side effects associated with Dorzolamide / Timolol, such as blurred vision, which may affect your ability to drive and/ or operate machinery. Do not drive or operate machinery until you feel well or your vision is clear.
Dorzolamide / Timolol contains benzalkonium chloride
If you wear soft contact lenses, you should remove contact lenses before using Dorzolamide / Timolol and wait at least 15 minutes before reinsertion (the preservative benzalkonium chloride may possibly discolour the lenses).
Benzalkonium chloride may cause ocular irritation.
3. HOW TO USE DORZOLAMIDE / TIMOLOL
Always use Dorzolamide / Timolol exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure. The appropriate dosage and duration of treatment will be established by your doctor.
The recommended dose is one drop in the affected eye(s) in the morning and in the evening.
If you are using Dorzolamide / Timolol with another eye drop, the drops should be instilled at least 10 minutes apart.
Do not change the dose of the drug without consulting your doctor.
Do not allow the tip of the container to touch the eye or areas around the eye. It may become contaminated with bacteria that can cause eye infections leading to serious damage of the eye, even loss of vision. To avoid possible contamination of the container, wash your hands before using this medicine and keep the tip of the container away from contact with any surface.
If you think your medication may be contaminated, or if you develop an eye infection, contact your doctor immediately concerning continued use of this bottle.
Instructions for use
Always wash your hands before applying eye drops.
Apply your eye drops in the following way:
1. Remove protective cap.
2. Tilt your head back and look at the ceiling.
3. Gently pull the lower eyelid down until there is a small pocket.
4. Squeeze the upturned dropper bottle to release a drop into your eye.
5. Whilst keeping the affected eye closed, press your finger against the corner of the closed eye (the side where the eye meets the nose) and hold for 2 minutes. This helps to stop timolol getting into the rest of the body.
Avoid touching the dropper tip against your eye or anything else.
Replace and tighten the cap straight after use.
If you use more Dorzolamide / Timolol than you should
If you put too many drops in your eye or swallow any of the contents of the container, among other effects, you may become light-headed, have difficulty breathing, or feel that your heart rate has slowed. Contact your doctor immediately.
If you forget to use Dorzolamide / Timolol
It is important to use Dorzolamide / Timolol as prescribed by your doctor. If you miss a dose, use it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and go back to your regular dosing schedule. Do not take a double dose to make up for the forgotten dose.
If you stop using Dorzolamide / Timolol
If you want to stop using this medicine talk to your doctor first.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
4. POSSIBLE SIDE EFFECTS
