1. What is Cosopt PF Multi and what is it used for
Cosopt PF Multi contains two active substances: dorzolamide and timolol.
- Dorzolamide belongs to a group of medicines called "carbonic anhydrase inhibitors".
- Timolol belongs to a group of medicines called "beta-adrenergic receptor blockers" (beta-adrenolytics). These medicines lower intraocular pressure by two different mechanisms.
Cosopt PF Multi is indicated for the treatment of glaucoma to lower elevated intraocular pressure, when beta-adrenergic blocking agents alone are not sufficient.
2. Important information before using Cosopt PF Multi
When not to use Cosopt PF Multi
- if you are allergic to dorzolamide hydrochloride, timolol maleate, or any of the other ingredients of this medicine (listed in section 6);
- if you currently have or have a history of respiratory problems, such as asthma or severe chronic obstructive pulmonary disease (a serious lung disease that may cause wheezing, breathing difficulties, and/or a long-lasting cough);
- if you have a slow heart rate, heart failure, or irregular heart rhythm;
- if you have severe kidney disease or severe kidney function disorders, or a history of kidney stones;
- if you have excessive acidification of the blood due to an accumulation of chloride ions in the body (hyperchloremic acidosis).
In case of doubt, consult your doctor or pharmacist before using this medicine.

3. How to use Cosopt PF Multi
Always use this medicine exactly as your doctor has told you.
The recommended dose is one drop in the affected eye(s) in the morning and evening.
If you are using other eye drops, wait at least 10 minutes between administering each medicine.
Do not change the dose of your medicine without consulting your doctor.
If you have difficulty administering the drops, ask a family member or caregiver for help.
Do not allow the tip of the multidose container to come into contact with the eye or its surroundings.
This can cause eye injury and contamination of the container with bacteria, which can lead to serious eye damage and vision loss.
To avoid possible contamination of the multidose container, wash your hands before using this medicine and avoid touching the tip of the container to any surface.
Instructions for use
Before administering the eye drops:
- Wash your hands before opening the bottle.
- Do not use the medicine if the protective ring around the neck of the bottle is damaged before the first use.
- Before administering the drops to the eye, try using the bottle with the dropper by slowly squeezing it until one drop is released from the bottle, away from the eye.
- If you are sure you can administer a single drop, take the most comfortable position for administration (you can sit, lie on your back, or stand in front of a mirror).
- When opening the bottle for the first time, discard the first drop of medicine away from the eye.
Administering the drops:
- 1. Hold the bottle directly under the cap and open it by twisting the cap. Do not touch the dropper tip to any surface to avoid contaminating the solution.
- 2. Tilt your head back and hold the bottle above the eye.
- 3. Pull the lower eyelid down and look up. Gently squeeze the bottle until the drop falls into the eye. Remember that it may take a few seconds from squeezing the bottle to the drop appearing. Do not squeeze too hard.


- 4. Close your eye and press the inner corner of your eye with your finger for about two minutes. This helps prevent the medicine from entering the entire body.

- 5. To administer the drops to the other eye, if instructed by your doctor, repeat steps 2 to 4. Consult your doctor about how to use this medicine, as sometimes only one eye needs treatment.
- 6. After each use, shake the bottle downwards to remove any remaining solution from the tip of the bottle. Do not touch the tip of the bottle. This is necessary to ensure further administration.
- 7. Wipe off any excess solution from the skin around the eyes.
- 8. After 2 months of using Cosopt PF Multi, a small amount of solution will remain in the bottle. Do not attempt to use the remaining medicine. Do not use the medicine for more than 2 months after opening the bottle.
If you have any doubts about how to administer the medicine, ask your doctor, pharmacist, or nurse.

If you miss a dose, use it as soon as possible. However, if it is almost time for your next dose, do not use the missed dose and return to your regular dosing schedule.
