Wash your hands before using eye medication.

To apply the eye drops: Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

• Wait at least 10 minutes before using any other eye drops your doctor has prescribed.

Use only the number of drops recommended on the medicine label.
