Proper Use

Use this medicine only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

If your doctor ordered two different eye drops to be used together, wait at least 5 minutes after you put the first medicine in your eye to use the second medicine. This will prevent the second medicine from “washing out” the first one.

To use the eye drops:

  • Wash your hands with soap and water before and after using this medicine.
  • Shake the eye drops well just before each use.
  • Tilt your head back and press your finger gently on the skin just beneath the lower eyelid. Pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed and apply pressure to the inner corner of the eye with your finger for 1 or 2 minutes to allow the medicine to be absorbed by the eye.
  • If you think you did not get the drop of medicine into your eye properly, repeat the directions with a second drop.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface, including the eye. Keep the container tightly closed when you are not using the drops.
  • If germs get in the bottle, your eye could become infected. Serious eye infections can cause blindness.
  • The eye drops will normally be a clear liquid with a greenish-yellow color. If the color changes or the liquid becomes cloudy, do not use the medicine. Get a new bottle from the pharmacy.

You should not use the eye drops if you have contact lenses in your eyes. Remove your contact lenses before you use this medicine. Wait at least 10 minutes after you use the medicine before putting the contact lenses back in.
