What Kind of Medicine is Laronidase?
Simply put, laronidase is a medicine that gives back a special enzyme your body is missing or does not make enough of. Think of enzymes as tiny workers in your body that help everything run smoothly and correctly.
People with MPS I lack a specific enzyme, which causes health challenges. Laronidase steps in to fill that gap. It helps control some symptoms of the condition.
Please remember that this medicine does not cure the disease completely. Even though it is not a cure, it reduces symptoms and makes life much easier to manage.
