Cosopt Eye Drops – Dorzolamide Timolol Eye Drops, 5ml
If you have been prescribed COSOPT eye drops, it is because your doctor has determined that beta-blocker eyedrop medicine alone is not adequate to lower the raised pressure in your eye associated with glaucoma. COSOPT contains two different medicines – dorzolamide and timolol – that work together to reduce pressure more effectively.
How does Cosopt eye drops work?
Dorzolamide belongs to a class of drugs called carbonic anhydrase inhibitors. Timolol, on the other hand, is a beta blocker. Both of these medications lower eye pressure in different ways. When used together, they provide much better relief than either one could on its own.
What is Glaucoma?
Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged.
It’s usually caused by fluid building up in the front part of the eye, which increases pressure inside the eye.
Glaucoma can lead to loss of vision if it’s not diagnosed and treated early.
It can affect people of all ages, but is most common in adults in their 70s and 80s.
Glaucoma does not usually cause any symptoms to begin with.
It tends to develop slowly over many years and affects the edges of your vision (peripheral vision) first.
For this reason, many people do not realise they have glaucoma, and it’s often only picked up during a routine eye test.
If you do notice any symptoms, they might include blurred vision, or seeing rainbow-coloured circles around bright lights.
Both eyes are usually affected, although it may be worse in 1 eye.
Very occasionally, glaucoma can develop suddenly and cause:
Visit an opticians or a GP if you have any concerns about your vision.
If you have glaucoma, early diagnosis and treatment can help stop your vision getting worse.
Without treatment, glaucoma can eventually lead to blindness.
If you develop symptoms of glaucoma suddenly, go to your nearest eye casualty unit or A&E as soon as possible.
This is a medical emergency that may require immediate treatment.
There are several different types of glaucoma.
The most common is called primary open angle glaucoma. This tends to develop slowly over many years.
It’s caused by the drainage channels in the eye becoming gradually clogged over time.
Other types of glaucoma include:
- acute angle closure glaucoma – an uncommon type caused by the drainage in the eye becoming suddenly blocked, which can raise the pressure inside the eye very quickly
- secondary glaucoma – caused by an underlying eye condition, such as inflammation of the eye (uveitis)
- childhood glaucoma (congenital glaucoma) – a rare type that occurs in very young children, caused by an abnormality of the eye
Glaucoma can occur for a number of reasons.
Most cases are caused by a build-up of pressure in the eye when fluid is unable to drain properly.
This increase in pressure then damages the nerve that connects the eye to the brain (optic nerve).
It’s often unclear why this happens, although certain things can increase the risk, including:
- your age – glaucoma becomes more common as you get older
- your ethnicity – people of African, Caribbean or Asian origin are at a higher risk
- your family history – you’re more likely to develop glaucoma if you have a parent or sibling with the condition
- other medical conditions – such as short-sightedness, long-sightedness and diabetes
It’s not clear whether you can do anything to prevent glaucoma, but having regular eye tests should pick it up as early as possible.

How to Use
How to use Cosopt Eye Drops
Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. Your doctor will establish the appropriate dosage and duration of treatment.
The recommended dose is one drop in the affected eye(s) in the morning and in the evening.
If you are using this medicine with another eye drop, the drops should be instilled at least 10 minutes apart.
Do not change the dose of the medicine 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 container.
Instructions for use
Do not use the container if the plastic safety strip around the neck is missing or broken. When opening the container for the first time, tear off the plastic safety strip.
Every time you use COSOPT:
1. Wash your hands.
2. Open the container. Take special care that the tip of the dropper container does not touch your eye, the skin around your eye or your fingers.
3. Tilt your head backwards and hold the container upside down over the eye.
4. Pull the lower eyelid downwards and look up. Hold and gently squeeze the container on the flattened sides of the container and let one drop fall into the space between the lower eyelid and the eye.
5. Press a finger into the corner of your eye, by the nose, or close your eyelids for 2 minutes. This helps to stop the medicine from getting into the rest of the body.
6. Repeat steps 3 to 5 with the other eye if instructed to do so by your doctor.
7. Put the cap back on and close the container tightly.
If you use more COSOPT than you should

If you stop using COSOPT
