1. Storage of Nitisinone MDK
2. Contents of the pack and additional information

The active ingredient of Nitisinone MDK is nitisinone. This medication is used for the treatment of a rare disease called hereditary tyrosinemia type 1 in adults, adolescents, and children (of any age).

In this disease, your body cannot completely break down the amino acid tyrosine (amino acids are the fundamental elements of proteins), forming toxic substances. These toxic substances accumulate in your body. Nitisinone MDK blocks the breakdown of tyrosine, and toxic substances do not form.

You must follow a special diet while taking this medication, because tyrosine will still be in your body. This diet is based on a low content of tyrosine and phenylalanine (another amino acid).

Do not take Nitisinone MDK

• if you are allergic to nitisinone or any of the other ingredients of this medicine (listed in section 6).

Do not breastfeed while taking this medicine (see section “Pregnancy and breastfeeding”).

Warnings and precautions

• Your ophthalmologist will examine your eyes before treatment and regularly during treatment with nitisinone. If you notice redness of the eyes or any other eye effect, contact your doctor immediately for an eye examination. Eye problems (see section 4) may be a sign of inadequate dietary control.

Blood samples will be taken during treatment to control whether the treatment is adequate and to ensure that there are no blood-related side effects.

You will have regular liver function checks because the disease affects the liver.

Your doctor should follow up every 6 months. If you experience any side effects, it is recommended to use shorter time intervals.

Blepharitis, an inflammation of the eyelids, is a rare adverse effect (affecting up to 1 in 100 people).

Other Common Adverse Effects
