How It Works
Travoprost is like a natural substance in your body. It works by helping fluid drain better from inside your eye. This lowers the pressure in your eye.
How to Take It
Use one drop in the affected eye(s) once a day in the evening. Do not use it more than once a day. Using it more often may make it less effective. If you use other eye drops, wait at least 5 minutes before using travoprost.
