1. What COSOPT Preservative-Free is and what it is used for
COSOPT Preservative-Free 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.
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.
2. What you need to know before you use COSOPT Preservative-Free
Do not use COSOPT Preservative-Free
- if you are allergic to dorzolamide hydrochloride, timolol maleate or any of the other ingredients of this medicine (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, dificulty 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 (hyperchloraemic acidosis).
If you are not sure whether you should use this medicine, contact your doctor or pharmacist.
Warnings and precautions
Talk to your doctor before using COSOPT Preservative-Free

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.

Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
Use in pregnancy
Do not use COSOPT Preservative-Free if you are pregnant unless your doctor considers it necessary.

Do not use COSOPT Preservative-Free 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.

Do not drive or operate machinery until you feel well or your vision is clear.
3. How to use COSOPT Preservative-Free
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.
Instructions for 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 sachet and fold the edge to close the sachet.
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.
If you are not sure how to administer your medicine, ask your doctor, pharmacist or nurse.
If you use more COSOPT Preservative-Free 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 COSOPT Preservative-Free
It is important to take COSOPT Preservative-Free 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.
