Proper Use

Drug information provided by: Micromedex

Your eye doctor will tell you how much of this medicine to use and how often. Do not use more medicine or use it more often than your doctor tells you to.

If you or your child are wearing contact lenses, remove them before you use cysteamine eye drops. Wait for at least 15 minutes before putting the contact lenses back in. Talk to your eye doctor about this if you have questions.

To use the eye drops:

  • First, wash your hands. Tilt the head back and, pressing 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 for 1 or 2 minutes to allow the medicine to be absorbed by the eye.
  • Immediately after using the eye drops, wash your hands to remove any medicine that may be on them.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, always keep the container tightly closed.
