3. How to use TRUSOPT

Follow exactly the instructions for administration of this medicine given by your doctor. If you are unsure, consult your doctor or pharmacist again. The appropriate dosage and duration of treatment will be determined by your doctor.

When this medicine is the only medicine used, the recommended dose is one drop in the affected eye(s) in the morning, afternoon, and evening.

If your doctor has recommended that you use this medicine with a beta-blocker eye drop to reduce eye pressure, the recommended dose is one drop of TRUSOPT in the affected eye(s) in the morning and evening.

If you use TRUSOPT with another eye drop, the drops should be instilled with a minimum time interval of 10 minutes.

Do not let the tip of the container touch the eyes or the areas surrounding them. It may be contaminated with bacteria that can cause eye infections leading to serious damage to the eyes, including loss of vision. To avoid possible contamination of the container, wash your hands before using this medicine and avoid touching the tip of the container to any surface. If you think your medicine may be contaminated, or if you develop an eye infection, consult your doctor immediately if you can continue using this container.

Instructions for use
