Description of the drug: 

This medication causes the pupillary dilation.


It is used mainly in the clinic for its quick and short-term effect when you want to dilate the pupil of animals to observe the bottom of their eyes. 

It can also be used to prevent synechiae (fibrous tissue in the eye that causes the iris to stick to the cornea or lens) to appear as a result of cataract surgery or to undo them when they form because of presence of inflammation in the eye.


Unless otherwise advised by the veterinarian, this drug should not be used in patients with glaucoma (increased pressure in the eye).

Side effects : 

Mydriacyl® application may result in intense light sensitivity, burning sensation , superficial inflammation of the cornea and drooling. 

The animal can also produce less tears for a few hours afterwards.

Form available : 

Mydriacyl® is available as drops.

Storage : 

Store at room temperature in a dry place protected from light.
