What is Cosopt eye drops?

Cosopt eye drops contain a combination of dorzolamide and timolol. Dorzolamide reduces the amount of fluid in the eye, which decreases pressure inside the eye. Timolol is a beta-blocker that also reduces pressure inside the eye.

Cosopt is a prescription eye drop solution used to treat open-angle glaucoma or ocular hypertension when a beta-blocking medicine alone does not work to control the eye pressure.

It is not known if Cosopt is safe and effective in children 2 years of age and younger.

Warnings

You should not use Cosopt eye drops if you have a history of asthma, chronic obstructive pulmonary disease (COPD), or a serious heart condition such as "AV block," slow heartbeats, heart failure, or if you have recently had a heart attack.

Cosopt can cause serious breathing problems or heart failure. Get medical help if you have shortness of breath, pounding heartbeats, swelling in your lower legs, or rapid weight gain.

How should I take Cosopt eye drops

USe Cosopt exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Do not Cosopt eye drops use while wearing soft contact lenses. A preservative in this medicine could permanently stain the lenses. Use the medicine at least 15 minutes before inserting your contact lenses.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Wash your hands before using eye medication.

Use only the number of drops your doctor has prescribed. Wait at least 5 minutes before using any other eye drops your doctor has prescribed.

Do not touch the tip of the Cosopt eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
