How To Use

This medication is for use in the eye(s). For best results, this medication must be used regularly as prescribed. Do not stop taking this medication without first consulting your doctor.

Tilt your head back, gaze upward and pull down the lower eyelid to make a pouch. Place dropper directly over eye and administer the prescribed number of drops. Look downward and gently close your eye for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure.
