It may also be used for other conditions; ask your doctor for more information.

How should I take tropicamide?

Use tropicamide as directed by your doctor. Check the label on the medicine for exact dosing instructions.

To remove contact lenses before using tropicamide.

First, wash your hands. Tilt your head back. Using your index finger, pull the lower eyelid away from the eye to form a pouch. Drop the medicine into the pouch and gently close your eyes. Immediately use your finger to apply pressure to the inside corner of the eye for 2 or 3 minutes after using the medicine. Do not blink. Keep your eyes closed for 2 or 3 minutes. Remove excess medicine around your eye with a clean tissue, being careful not to touch your eye. Wash your hands to remove any medicine that may be on them.
