How to Use This Medicine:

Liquid, Drop

  • Take your medicine as directed.
  • Wash your hands with soap and water before and after using this medicine.
  • Shake the eye drops well just before each use.
  • Lie down or tilt your head back. With your index finger, pull down the lower lid of your eye to form a pocket.
  • To use the eye drops: Hold the dropper close to your eye with the other hand. Drop the correct number of drops into the pocket made between your lower lid and eyeball. Gently close your eyes. Place your index finger over the inner corner of your eye for 1 minute. Do not rinse or wipe the dropper or allow it to touch anything, including your eye. Put the cap on the bottle right away. Keep the bottle upright when you are not using it.
  • If you think you did not get the drop of medicine into your eye properly, repeat the directions with a second drop.
  • 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.
  • 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.
