No. Tyrosinemia Type 1 is a lifelong condition and it’s important to maintain recommended medication and dietary routines to lower the risk of adverse health outcomes.

NITYR Tablets contain nitisinone, which prevents the build-up of toxic substances which cause severe liver and kidney problems in patients with Tyrosinemia Type 1. Patients still need to follow a low-protein diet, restricting the intake of phenylalanine and tyrosine to control tyrosine levels in the body.
