What is Cystadrops?
Cysteamine works by reducing the amount of cystine (an amino acid) in the body. Cysteamine is used in people 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.
Cystadrops (for the eyes) is used to keep cystine crystals from building up in the cornea (surface of the eye).
Cystadrops may also be used for purposes not listed in this medication guide.
