This medication is used to widen (dilate) the pupil of the eye in preparation for certain eye examinations. It belongs to a class of drugs known as anticholinergics. Tropicamide works by relaxing certain eye muscles.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used for swelling in different parts of the eye (such as iritis, iridocyclitis, keratitis).

Use this medication in the eye(s) as directed by your doctor, usually 15 to 20 minutes before an eye examination.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

If you are wearing contact lenses, remove them before using this medication. Ask your doctor when you may replace your contact lenses.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place 1 or 2 drops into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure for 2 to 3 minutes. This will prevent the medication from draining out and being absorbed by your body. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed.

Do not rinse the dropper. Replace the dropper cap after each use.

If you are using another kind of eye medication (such as drops or ointments), wait at least 5 to 10 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.
