Latanoprost Yonsung is an eye drop that lowers high pressure in your eyes, helping to treat open-angle glaucoma and ocular hypertension.
One drop in the affected eye(s) once a day.
Apply the drops in the evening. Wash your hands, gently pull your lower eyelid down, and place one drop into your eye without touching the eye with the dropper tip. Close your eye and press the corner near your nose for one minute. Remove contact lenses before use and wait 15 minutes before reinserting. If using other eye drops, wait at least 5 minutes between applications.
Do not use more than once a day, as using it more often may make it less effective.
