What is in this leaflet
This leaflet answers some common questions about Orfadin hard capsules. It does not contain all of the available information. Reading this leaflet does not take the place of talking to your doctor.
All medicines have risks and benefits. Your doctor has weighed the risks of your taking Orfadin against the benefits they expect it will have for you.
If you have any concerns about taking Orfadin, ask your doctor.
Keep this leaflet with the medicine. You may want to read it again.
What OFRADIN is used for
Orfadin contains a medicine called nitisinone which is used for the treatment of a disease called hereditary tyrosinaemia type 1. In this disease the body is unable to completely break down the amino acid tyrosine. Harmful substances will be formed and accumulated 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 (with low 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 Orfadin has been prescribed for you.
Your doctor may have prescribed it for another use.
Orfadin is not addictive.
Orfadin is only available on a doctor's prescription.
