What ORFADIN is used for

ORFADIN contains a medicine called nitisinone which is used for the treatment of a disease called hereditary tyrosinaemia type 1 (HT-1). In this disease the body is unable to completely break down the amino acid tyrosine. Harmful substances can form and accumulate in the body.
ORFADIN blocks the breakdown of tyrosine and by doing so the harmful substances are not formed. However, tyrosine will remain in the body and therefore a special diet that is low in tyrosine and phenylalanine content must be followed when taking ORFADIN.
Nitisinone belongs to a group of medicines called 'other alimentary and metabolism products'.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
ORFADIN is not addictive.
ORFADIN is available only with a doctor's prescription.
