Wash your hands before using the eye drops.
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 with the tip down. Look up and away from the dropper as you squeeze out a drop, then close your eye.
  • Use only the number of drops your doctor has prescribed.
  • Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct. If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
  • Do not allow the dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
