USES OF DORTAS

Treats increased pressure in the eye

HOW DORTAS WORKS

Dorzolamide blocks the action of an enzyme called carbonic anhydrase. By blocking this enzyme, it reduces the amount of fluid in the front part of the eye, and thus helps in lowering the pressure within the eye.

Tilt your head back and gently pull your lower eyelid down to form a small pocket between your eyelid and your eye. Turn the bottle upside down and squeeze it until a single drop is dispensed into the eye as directed by your doctor. Put the cap back on and close the bottle straight after you have used it. It is for external use only. Check the label for directions before use.
