Cosopt is a combination medicine consisting of dorzolamide and timolol. Dorzolamide reduces fluid in the eye, decreasing eye pressure. Timolol is a beta-blocker that also decreases eye pressure. Cosopt is used to treat some types of glaucoma and other conditions that cause high pressure in the eye. Cosopt is not for use in children under 2 years old.
Do not use Cosopt while wearing contact lenses; wait 15 mins before putting lenses back in. Wash your hands before application. Wait 5 minutes between drops if you are prescribed multiple drops. Wait 10 minutes before using other prescribed eye drops. Do not touch the dropper to your eye. Do not use if liquid is discolored or has particulates. You may need to temporarily cease Cosopt use if you undergo surgery. Follow your doctor’s instructions on how to apply eye drops properly.
Do not use Cosopt if you have a history of asthma, COPD, serious heart conditions, or a recent heart attack. Do not use Cosopt if you are allergic to either dorzolamide or timolol. Tell your doctor your medical history before starting on Cosopt, especially if you have narrow-angle glaucoma, breathing issues, heart conditions, diabetes, muscle disorders, and kidney, liver, or thyroid disease. Also tell your doctor if you become pregnant or breast-feed. Overdose symptoms include: shortness of breath, confusion, breathing problems, abnormal pulse, fainting, convulsions, and chest pain. Use caution when driving. Do not use other eye medications unless directed by physician.
Get emergency medical assistance if you suspect an allergic reaction or possible overdose. Be aware of Cosopt’s side effects if it is absorbed into your bloodstream; these side effects can be more serious than Cosopt used in the eye. Stop using Cosopt and tell your doctor immediately if you experience side effects like: swelling/redness of eyelids, eye pain, light sensitivity, crusting and oozing of the eyelids, breathing issues, swelling, rapid weight gain, or severe skin reactions. More common side effects include: unusual taste in mouth, blurry vision, stinging, and itching in eyes. Cosopt may interact with other medications, so tell your doctor about the other drugs you may be taking.
