P - Caution when used during pregnancy

Tropicamide (Mydriacyl) is an anticholinergic used as a mydriatic.



Tropicamide is a tertiary amine antimuscarinic which causes relaxation of the sphincter muscle of the iris resulting in pupillary dilatation. It also causes paralysis of the ciliary muscle leading to loss of accommodation.


Mydriasis: 20-40 minutes; cycloplegia: 30 minutes.

Mydriasis: 6 hours; cycloplegia: 6 hours.

Tropicamide Adverse Reactions / Tropicamide Side Effects

Increased intraocular pressure, transient stinging, dry mouth, blurred vision, photophobia, tachycardia, headache, superficial punctate keratitis, systemic anticholinergic effects, severe CNS disturbances in children (rare).


In the elderly and others where increased intraocular pressure may be encountered, mydriatics and cycloplegics should be used cautiously. To avoid inducing angle closure glaucoma, an estimation of the depth of the angle of the anterior chamber should be made. The lacrimal sac should be compressed by digital pressure for two to three minutes after instillation to avoid excessive systemic absorption.

Special Precautions

Elderly, children, pregnancy. Hypertension, hyperthyroidism, DM, cardiac disorders. To reduce systemic absorption, press on the lacrimal sac for 1-2 minutes following instillation. Do not drive or engage in hazardous activities and protect eyes from bright illumination when pupils are dilated. May fail to produce adequate cycloplegia in children.

Other Drug Interactions

May antagonise effects of ophthalmic carbachol, pilocarpine, or cholinesterase inhibitors.
