This medication contains two ingredients used to lower pressure in the eye if you have certain medical conditions such as glaucoma.  If the high pressure is not reduced, it could eventually damage your sight. 

How to Use

  • Wash your hands.

  • Before using the medication for the first time, be sure the Safety Strip on the front of the bottle is unbroken.  A gap between the bottle and the cap is normal for an unopened bottle.

  • Tear off the Safety Strip to break the seal.

  • To open the bottle, unscrew the cap by turning as indicated by the arrows on the top of the cap.  Do not pull the cap directly up and away from the bottle.  Pulling the cap directly up will prevent your dispenser from operating properly.

  • Tilt your head back and pull your lower eyelid down slightly to form a pocket between your eyelid and your eye. 

  • Invert the bottle and press lightly with the thumb or index finger over the “Finger Push Area” until a single drop is dispensed into the eye.

  • Do not let the dropper tip touch your eye or any other surface.

  • Press a finger into the corner of your eye, by the nose, for 2 minutes.  This helps keep the medicine in your eye.

  • If drop dispensing is difficult after opening for the first time, replace the cap on the bottle and tighten slightly and then remove by turning the cap in the opposite directions as indicated by the arrows on the top of the cap.

  • Replace the cap by turning until it is firmly touching the bottle.  Do not overtighten or you may damage the bottle and cap.
