What is idursulfase?
Idursulfase contains a natural enzyme that some people lack because of a genetic disorder. Idursulfase helps replace this missing enzyme.
Idursulfase is used to treat some of the symptoms of a genetic condition called Hunter's syndrome, also called mucopolysaccharidosis (MYOO-koe-pol-ee-SAK-a-rye-DOE-sis).
Hunter syndrome is a metabolic disorder in which the body lacks the enzyme needed to break down certain natural substances. These substances can build up in the body, causing enlarged organs, abnormal bone structure, changes in facial features, breathing problems, heart problems, vision loss, and changes in mental or physical abilities.
Idursulfase may improve walking ability in people with this condition. However, this medication is not a cure for Hunter syndrome.
Idursulfase may also be used for purposes not listed in this medication guide.
