Cosopt

Generic name: Dorzolamide hydrochloride, Timolol maleate

Why is Cosopt prescribed?

Cosopt lowers high pressure in the eye, a problem typically caused by the condition known as open-angle glaucoma. Cosopt works by reducing production of the liquid that fills the eyeball.

Most important fact about Cosopt

Although it often causes no symptoms at first, high pressure in the eye will eventually damage the optic nerve and lead to blindness. It's therefore very important to keep using this medicine even if your eyes seem okay.

How should you take Cosopt?

Cosopt is administered with an eyedropper bottle. If you are using other eyedrops or ointments, allow at least 10 minutes between doses of each product.

The benzalkonium chloride used as a preservative in Cosopt can be absorbed by soft contact lenses; wait 15 minutes after using the drug before you insert the lenses.

To apply the drops, first wash your hands, then tilt your head back and pull your lower eyelid down slightly to form a pocket between the lid and the eye. Turn the bottle upside down and press the "Finger Push Area" lightly with your thumb or index finger until one drop falls into the eye. Be careful to avoid touching the eyelids with the dropper tip. This could contaminate the solution.

• If you miss a dose...
  Take the forgotten dose as soon as you remember. However, if it is almost time for your next dose, skip the one you missed and return to your regular schedule. Do not take two doses at once.

• Storage instructions...
  Store at room temperature. Protect from light.
