Description:
Cysteamine is used to treat a condition called nephropathic cystinosis (NEF-roe-PATH-ik SIS-tin-OH-sis). It works by reducing the amount of cystine in the kidneys.
Nephropathic cystinosis is a rare genetic condition. Children with this condition develop a build-up of cystine in the kidneys, which can lead to kidney failure and other medical problems.
