Cosopt Preservative-Free is a medication that comes in the form of eye drops and is used to reduce elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension.

The active ingredients in Cosopt Preservative-Free are dorzolamide and timolol, which belong to the class of drugs known as carbonic anhydrase inhibitors and beta-blockers, respectively.

As the name suggests, Cosopt Preservative-Free is a version of Cosopt that does not contain preservatives.

Use and Dosage

Read the Patient Information Leaflet if available from your pharmacist before you start using timolol/dorzolamide and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Use this medication in the affected eye(s) as directed by your doctor, usually one drop 2 times a day.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

Some products contain a preservative that may be absorbed by contact lenses. If you are using a product with a preservative and you wear contact lenses, remove the lenses before using the eye drops. Wait at least 15 minutes before putting in your contact lenses.

Tilt your head back, look upward and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop in your eye. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. Try not to blink and do not rub your eye. This will prevent the medication from draining out. Repeat these steps for your other eye if so directed.

Do not rinse the dropper. Replace the dropper cap after each use.

If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.

Use this medication regularly to get the most benefit from it. To help you remember, use it at the same times each day. Keep using this medication even if you feel well. Most people with glaucoma or high pressure in the eyes do not feel sick.
