Dorzolamide / Timolol contains two medicines: dorzolamide and timolol.
• Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors”.
• Timolol belongs to a group of medicines called "beta blockers”.
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.
Do not use Dorzolamide / Timolol
• if you are allergic (hypersensitive) to dorzolamide hydrochloride, timolol maleate or any of the other ingredients of Dorzolamide Timolol (listed in section 6).
• if you have now or had in the past respiratory problems, such as asthma or severe chronic obstructive bronchitis (severe lung disease which may cause wheeziness, difficulty in breathing and/or long-standing cough)
• if you have a slow heart beat, heart failure or disorders of heart rhythm (irregular heart beats)
• if you have severe kidney disease or problems, or a prior history of kidney stones
• if you have excess acidity of the blood caused by a build up of chloride in the blood (hyperchloremic acidosis).
If you are not sure whether you should use Dorzolamide / Timolol, contact your doctor or pharmacist.

Driving and using machines
No studies on the effects on the ability to drive or use machines have been performed.

Do not drive or operate machinery until you feel well or your vision is clear.
Dorzolamide / Timolol Tubilux Pharma 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.
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.
