What is Cosopt (Timolol Maleate/Dorzolamide Hydrochloride) used for?

Cosopt (Timolol Maleate/Dorzolamide Hydrochloride) is an ophthalmic medication used to treat patients suffering from open angle glaucoma or pseudo-exfoliative glaucoma. It lowers the amount of fluid in the eye to alleviate pressure and reduce symptoms associated with this condition such as pain, loss of vision, or potential damage to the optic nerve. Your physician may also prescribe it to treat other conditions that are not listed here.

How should I use Cosopt (Timolol Maleate/Dorzolamide Hydrochloride)?

Always follow the instructions provided by your physician while using Cosopt (Timolol Maleate/Dorzolamide Hydrochloride) to get the best results. The typical dosage is one drop administered each day, but your particular instructions may differ based on the condition being treated, your current health, and the severity of your symptoms. Wash your hands before using the medicine to remove any contaminants or dirt. Gently shake the bottle before application to mix its contents and observe the solution to make sure it is not cloudy or discolored as this may indicate contamination. To use the medicine tilt your head back slightly, pull down the lower lid of the eye being traeted, hold the bottle over the eye, and dispense one drop into the pouch that is formed. Slowly close the eyelid to spread the medicine and keep the eye closed for ten seconds allowing the medication to be absorbed. Never allow the tip of the bottle to touch any foreign surfaces, including the eye itself, to prevent contamination. It is also suggested to wash your hands after each administration to prevent the solution from contacting areas not being treated or the mucous membranes. Ask your physician any questions you have about the medicine to ensure the correct administration.
