Contents of the pack
Miglustat contains the active substance miglustat, which belongs to a group of medicines that have an effect on metabolism. It is used to treat two disorders:
In type 1 Gaucher disease, your body cannot break down a substance called glucosylceramide. As a result, it builds up in some cells of your immune system. This can lead to an enlarged liver and spleen, changes in the blood, and effects on the bones.
The usual treatment for type 1 Gaucher disease is enzyme replacement therapy (ERT). Miglustat will only be used in cases where enzyme replacement therapy is not suitable for the patient.
If you have Niemann-Pick disease type C, lipids such as glycosphingolipids can build up in the cells of your brain. This can lead to problems with neurological functions such as slow eye movements, balance, swallowing, memory, or seizures.
Miglustat works by inhibiting the enzyme called glucosylceramide synthase, which is responsible for the first step in the synthesis of most glycosphingolipids.
Do not take miglustat
Warnings and precautions
Talk to your doctor or pharmacist before you start taking miglustat
Your doctor will perform the following tests before and during your treatment with this medicine:
These tests are necessary because some patients have reported symptoms such as tingling or numbness in hands and feet, or weight loss during treatment with miglustat. The tests will help your doctor determine if these effects are due to your disease or existing conditions or are side effects of miglustat (see section 4 for more details).
If you have diarrhea, your doctor may ask you to modify your diet to reduce lactose and carbohydrate intake, such as sucrose (cane sugar), or not to take miglustat with food, or to temporarily reduce the dose. In some cases, your doctor may prescribe medications to treat diarrhea, such as loperamide. There have been reports of Crohn's disease (an inflammatory disease that affects the intestine) in patients with Niemann-Pick disease type C treated with miglustat. If diarrhea does not respond to these measures or if you experience any other abdominal discomfort, talk to your doctor. In this case, your doctor may decide to perform additional tests.
Male patients are advised to use reliable contraceptive methods during treatment with miglustat and for three months after stopping treatment.
Children and adolescents
Do not give this medicine to children and adolescents (under 18 years of age) with type 1 Gaucher disease because it is not known if it works in this disease.
Other medicines and Miglustat Accord

If you take more miglustat than you should
