What is cysteamine ophthalmic (Cystaran)?
Cysteamine works by reducing the amount of cystine (an amino acid) in the body. Cysteamine is used in children with cystinosis (SIS-tin-OH-sis), a rare genetic condition that causes a build-up of cystine in the kidneys and other organs, including the eyes. Too much cystine can cause kidney failure or other medical problems.
Cysteamine ophthalmic (for the eyes) is used to keep cystine crystals from building up in the cornea (surface of the eye).
Cysteamine ophthalmic may also be used for purposes not listed in this medication guide.

How should I use cysteamine ophthalmic (Cystaran)?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

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 and squeeze out a drop.
- Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
- Use only the number of drops your doctor has prescribed.
- Wait at least 10 minutes before using any other eye drops your doctor has prescribed.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
