How Does Trusopt Work?

By inhibiting this enzyme, Trusopt lowers the eye pressure and decreases the amount of fluid the eye produces (known as aqueous humor).

When and How to Use It

General considerations to keep in mind during treatment with Trusopt include the following:

This medication comes in the form of an eye drop. It is used in the affected eye(s) three times a day.
Soft contact lenses can absorb the preservative (benzalkonium chloride) in these eye drops. In order to avoid this problem, you must remove the lenses before using Trusopt and wait at least 15 minutes before reinserting them.
If you use other eye drops in addition to Trusopt, wait at least 10 minutes between using Trusopt and the other eye medication.
In order to prevent contamination of the drops, do not touch the tip of the dropper to any surface, including the surface of the eye or the skin.
For Trusopt to work properly, it must be taken as directed.
