Generic Name: vestronidase alfa (ves TRON i dase AL fa)
Brand Name: Mepsevii
What is Mepsevii?
Mepsevii contains an enzyme that occurs naturally in the body in healthy people. Some people lack this enzyme because of a genetic disorder. This medicine helps replace this missing enzyme in such people.
MPS VII 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 or hearing loss, and changes in mental or physical abilities.
Mepsevii may improve walking ability in people with this condition. However, this medication is not a cure for MPS VII.
Mepsevii may also be used for purposes not listed in this medication guide.
An allergic reaction may occur during or shortly after infusion of Mepsevii. Tell your caregivers or get emergency medical help right away if you have any signs of a severe allergic reaction, such as sweating, trouble breathing, pale skin, blue lips or fingernails, and feeling like you might pass out.
