Cosopt Eye Drops – Dorzolamide and Timolol Eye Drops, 5ml
Dual-Action Glaucoma & Eye Pressure Relief for Humans, Dogs & Cats
Cosopt Eye Drops (Dorzolamide 2% and Timolol 0.5%) are prescription-only eye drops used to treat open-angle glaucoma and ocular hypertension. This dual-action medication reduces high intraocular pressure (IOP) by combining two active ingredients: Dorzolamide, which decreases fluid production in the eye, and Timolol, which slows fluid drainage. Together, they help prevent optic nerve damage and vision loss.
Cosopt is also commonly used in veterinary care for dogs and cats with elevated eye pressure. Available in a 5ml dropper bottle, Cosopt offers reliable, fast-acting pressure control.
If you have been diagnosed with glaucoma, your doctor may have prescribed COSOPT eye drops to help lower the pressure in your eye. COSOPT is a dual action medication, meaning it contains both a beta-blocker and a carbonic anhydrase inhibitor. This unique combination makes COSOPT an effective treatment option when used alone or in conjunction with other eyedrop medications.
When used as directed, COSOPT can help to relieve the symptoms of glaucoma and preserve your vision. The active ingredients in COSOPT work by reducing the production of fluid in the eye and improving the outflow of that fluid. This helps to lower the intraocular pressure (IOP
COSOPT eye drops contain two ingredients: dorzolamide and timolol.
- Dorzolamide belongs to a group of medicines called “carbonic anhydrase inhibitors”.
- Timolol belongs to a group of medicines called “beta-blockers”.

How To Use
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 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.
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 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.
It is important to use this medicine 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.
Do not use a double dose to make up for the forgotten dose.
If you want to stop using this medicine talk to your doctor first.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
