What is Tropicamide ?
Tropicamide has an anticholinergic property and is a synthetic muscarinic antagonist with actions similar to atropine. Tropicamide blocks the muscarinic receptors in the sphincter and ciliary muscle in the eye upon ocular administration. This inhibits cholinergic stimulus responses, causing pupil dilation and ciliary muscle paralysis. Tropicamide is a diagnostic agent which is used for producing short-duration mydriasis and cycloplegia.
Tropicamide stimulates the relaxation of the muscles in the eye. This dilates (widens) the pupil so that when your doctor shines an exam light into your eye, it does not respond (narrow). The ophthalmic tropicamide (for the eyes) is used for an eye test or other medical treatment to dilate the pupil.

How to use Tropicamide?
- For applying the eye drops wash your hands first. To avoid any contamination avoid touching the dropper tip or let it touch your eyes or any other surface.
- If you are wearing any contact lenses, remove them before using the medication. Ask the doctor when you should remove your contact lenses.
- Tilt your head back, look upward and pull down the lower eyelid for making a pouch. Hold the dropper directly over the eye and place 1 or 2 drops in the pouch. The medication should be used 15 to 20 minutes before an eye examination or as directed by the doctor. Look downward and gently close the eyes for atleast 1 to 2 minutes. Place atleast one finger at the corner of the eye and apply gentle pressure for atleast 2 to 3 minutes. It will prevent the medication from draining out and being absorbed by the body. Avoid blinking or rubbing your eyes. If you are using any other eye medications wait for 5 to 10 minutes before applying any other medications. Use the eye drops before applying eye ointments for allowing the drops to enter the eye.
Missed Dose
Since tropicamide ophthalmic is usually administered only during an eye test, you are not likely to be on a dosing schedule. Apply the missing dose as soon as you recall, if you are on a schedule. If it is almost time for your next dose, skip the missed dose. Avoid using extra dose to make up for the missed dose.
Overdose
Overdose of a drug can be accidental. If you have used more than the prescribed tropicamide then there is a chance of getting a harmful effect on the eyes. Overdose of a medicine can lead to some medical emergency.
