Trusopt is a prescription medication used to treat increased pressure in the eye caused by conditions such as open-angle glaucoma and ocular hypertension. It contains the active ingredient dorzolamide which belongs to a class of drugs known as carbonic anhydrase inhibitors and works by decreasing the amount of fluid within the eye.

Use and Dosage

Before applying Trusopt Eyedrops, Wash your hands before handling the eye drops. Do not touch the dropper tip or let it touch your eye or any other surface to avoid contamination. The usual recommended dose for adults is one drop in the affected eye(s) three times daily. If you wear contact lenses, remove them before using the eye drops with preservative. Wait at least 15 minutes after using the medication before putting in your contact lenses.

Follow these steps to use Trusopt Eye Drops as directed by your doctor:

  1. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch.
  2. Hold the dropper above your eye and place one drop into the pouch of your lower eyelid.
  3. Close your eyes gently for 1 to 2 minutes and apply gentle pressure with your finger at the corner of your eye near the nose. This will prevent the medication from draining out and improve its absorption.
  4. Repeat these steps for your other eye if required.
  5. Replace the dropper cap after each use.
  6. Don't rinse the dropper.

If you are using other eye medications, wait at least 10 minutes before applying them. Use eye drops before eye ointments to allow the drops to enter your eyes. Use Trusopt regularly at the same times each day as prescribed by your doctor. Even if you feel well, keep using the medication as most people with glaucoma or high pressure in the eyes do not feel sick.
