Patient information leaflet

What is it and what is it used for?

The active ingredient of Orfadin is nitisinone. Orfadin is used for treatment of a rare disease called hereditary tyrosinemia type 1.

In this disease your body is unable to completely break down the amino acid tyrosine (amino acids are building blocks of our proteins), forming harmful substances. These substances are accumulated in your body.
Orfadinblocks the breakdown of tyrosine and the harmful substances are not formed.

You must follow a special diet while you are taking Orfadin, because tyrosine will remain in your body. This special diet is based on low tyrosine and phenylalanine content.

  • if you get red eyes or any other signs of effects on the eyes. Contact your doctor immediately for an eye examination. Eye problems could be a sign of inadequate dietary control.

During the treatment, blood samples will be drawn in order for your doctor to check whether the treatment is adequate and to make sure that there are no possible side effects causing blood disorders.

Your liver will be checked at regular intervals because the disease affects the liver.

Follow-up by your doctor should be performed every 6 months. If you experience any side effects, shorter intervals are recommended.
