How should I use Trusopt?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Do not use while wearing soft contact lenses. A preservative in Trusopt could permanently stain the lenses. Wait at least 15 minutes before inserting your contact lenses.

Wash your hands before using the eye drops.

To apply the eye drops: Pull down your lower eyelid to create a small pocket and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

Use only the prescribed number of drops.

Wait at least 10 minutes before using any other eye drops.

Do not touch the dropper tip or place it directly on your eye. A contaminated dropper can infect your eye and lead to serious vision problems.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.

Store at room temperature, in an upright position and tightly closed. Do not freeze.

Tell your doctor right away if you have any eye injury, infection, or surgery. You may need to stop using Trusopt for a short time.

What happens if I miss a dose?

Use the medicine as soon as possible, but skip the missed dose if it is nearly time for your next dose. Do not use two doses at the same time.
