What DORZOLAMIDE/ TIMOLOL SANDOZ 20/5 is used for
DORZOLAMIDE/TIMOLOL SANDOZ 20/5 is used to 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 SANDOZ 20/5 helps control your glaucoma it does not cure it.
DORZOLAMIDE/TIMOLOL SANDOZ 20/5 contains two active ingredients, dorzolamide hydrochloride and timolol 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 hydrochloride belongs to a family of medicines called carbonic anhydrase inhibitors.
Timolol maleate belongs to a family of medicines called beta-blockers.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.

Using your eye drops at the same time each day will have the best effect on your eye pressure. It will also help you remember when to use the eye drops.
After using DORZOLAMIDE/TIMOLOL SANDOZ 20/5, wait at least 10 minutes before putting any other eye drops in your eye(s).
How to use it
You may find it easier to put drops in your eye while you are sitting or lying down.
If you are wearing soft contact lenses, remove them before putting the drops in your eye.
- Wash your hands before touching your eyes and before opening the bottle and touching the bottle tip.
- Do not allow the tip of the container to touch your eye or areas around your 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, keep the tip of the container away from contact with any surface.
- You must not use the bottle if the tamper-proof seal on the bottle neck is broken before you first use it.
- To open the bottle unscrew the cap by turning it until the tamperproof seal breaks.
- Tilt your head back and pull your lower eyelid down slightly to form a pocket between your eyelid and your eye.
- Invert the bottle, and press gently until a single drop as instructed by your doctor is dispensed into your eye.
DO NOT TOUCH YOUR EYE OR EYELID WITH THE TIP OF THE CONTAINER.
- Repeat steps 5 and 6 with the other eye if instructed to do so by your doctor.
- Re-close the bottle by turning the cap firmly immediately after use and return the bottle to the original outer carton.
- The dispenser tip is designed to provide a pre-measured drop; therefore, do not enlarge the hole of the dispenser tip.
- After using DORZOLAMIDE/ TIMOLOL SANDOZ 20/5 press a finger into the corner of your eye, by the nose for 2 minutes. This helps to stop timolol getting into the rest of the body.
Wait at least 15 minutes before replacing your contact lenses.
You may feel a slight burning sensation in the eye after using the eye drops.
If this persists, or is very uncomfortable, contact your doctor or pharmacist.

If you forget to use it
