How do I use it?

Use this medicine exactly as your health care provider prescribes. Do not use more of it or use it more often than prescribed. Using this medicine too much may increase the risk of side effects.

Wash your hands thoroughly before applying medicine to your eyes. Shake the medicine well before using. Tilt your head back and gently pull your lower eyelid down to form a pouch. Hold the dropper directly above your eye, look up, and squeeze a drop of the medicine into the pouch. Close your eyes for a minute or two and with a fingertip press gently on the inside corner of your eye to keep the medicine from draining out. Do not rub your eyes.

To avoid contaminating the medicine, do not let the tip of the dropper touch your eye or any other surface. After use, wipe the tip with a clean tissue, and put the cap on tightly.

If you miss a dose, use it as soon as you remember unless it is almost time for the next scheduled dose. In that case, skip the missed dose and use the next one as directed. Do not use double doses. If you are not sure of what to do if you miss a dose, or if you miss more than one dose, contact your health care provider.
