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

If you develop any eye irritation or any new eye problems such as redness of the eye or swelling of the eyelids, contact your doctor immediately.
If you suspect that COSOPT Preservative-Free is causing an allergic reaction or hypersensitivity (for example, skin rash, severe skin reaction, or redness and itching of the eye), stop using this medicine and contact your doctor immediately.
Tell your doctor if you develop an eye infection, receive an eye injury, have eye surgery, or develop a reaction including new or worsening symptoms.
When COSOPT Preservative-Free is instilled into the eye it may affect the entire body.

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

Always use this medicine exactly as your doctor has told you. 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 COSOPT Preservative-Free 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.
If you have difficulty administering your eye drops, seek the assistance of a family member or carer.
Do not allow the single dose container to touch the eye or areas around the eye. It could cause injury to your eye. It may also 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 single dose container, wash your hands before using this medicine and keep the tip of the single dose container away from contact with any surface. A new single dose container should be opened immediately prior to each use; there is enough solution in each container for both eyes if your doctor has told you to use the drops in both eyes
Discard the opened container with any remaining contents immediately after use.
Open the foil sachet which contains the individual single dose containers. Write the date of first opening on the sachet.
Every time you use COSOPT Preservative-Free
1. Wash your hands
2. Take the strip of containers from the sachet
3. Detach one single dose container from the strip .
4. Put the remaining strip back in the pouch and fold the edge to close the pouch.
5. To open the container, twist off the tab. (Picture A)
6. Hold the container between your thumb and index finger. Note that the tip of the container must not show more than 5 mm above the edge of your index finger. (Picture B)
7. Tilt your head backwards or lie down. Place your hand on your forehead. Your index finger should be aligned with your eyebrow or resting on the bridge of the nose. Look up. Pull the lower eyelid downwards with the other hand. Do not allow any part of the container to touch your eye or any area around your eye. Gently squeeze the container to let one drop fall into the space between the lid and the eye (Picture C). Do not blink while applying the drop to your eye. Each single dose container contains enough solution for both eyes.
8. Close your eye and press the inner corner of the eye with your finger for about two minutes. This helps to stop the medicine from getting into the rest of the body (Picture D).
9. Wipe off any excess solution from the skin around the eye.
If your doctor has told you to use drops in both eyes, repeat steps 7 to 9 for your other eye.
After putting the drop into the eye(s), throw away the used single dose container even if there is solution remaining to avoid contamination of the preservative free solution.
Store the remaining containers in the foil sachet; the remaining containers must be used within 15 days after opening of the sachet. If there are any containers left 15 days after opening the sachet they should be safely thrown away and a fresh sachet opened. It is important to continue to use the eye drops as prescribed by your doctor.
