Patient information leaflet

What is it and what is it used for?

Zavesca belongs to a group of medicines that affect metabolism. It is used to treat two conditions:

  • Zavesca is used to treat mild to moderate type 1 Gaucher disease.

In type 1 Gaucher disease, a substance called glucosylceramide is not removed from your body. It starts to build up in certain cells of the body?s immune system. This can result in liver and spleen enlargement, changes in the blood, and bone disease.

The usual treatment for type 1 Gaucher disease is enzyme replacement therapy. Zavesca is only used when a patient is considered unsuitable for treatment with enzyme replacement therapy.

  • Zavesca is also used to treat progressive neurological symptoms in Niemann-Pick type C disease.

If you have Niemann-Pick type C disease, fats such as glycosphingolipids build up in the cells of your brain. This can result in disturbances in neurological functions such as eye movements, balance, swallowing, and memory, and in seizures.

Zavesca works by inhibiting the enzyme called ?glucosylceramide synthase? which is responsible for the first step in the synthesis of most glycosphingolipids.

What should you consider before use?

Do not take Zavesca
  • if you are allergic (hypersensitive) to miglustat or any of the other ingredients of Zavesca. If this applies to you, tell your doctor. Don?t take Zavesca.
Take special care with Zavesca
  • if you suffer from kidney disease
  • if you suffer from liver disease If any of these apply to you, tell your doctor before you take Zavesca.

Your doctor will perform the following tests before treatment and during treatment with Zavesca:

  • an examination to check the nerves in your arms and legs - measurement of vitamin B 12 levels
  • monitoring growth if you are a child or adolescent with Niemann-Pick type C disease
  • monitoring of blood platelet counts if you are a patient with Niemann-Pick type C disease

The reason for these tests is that some patients have had tingling or numbness in the hands and feet, or a decrease in body weight, while taking Zavesca. The tests will help the doctor decide whether these effects are due to your disease or other existing conditions, or due to side effects of Zavesca (see section 4 for further details).

If you have diarrhoea, your doctor may ask you to change your diet to reduce your lactose and carbohydrate intake, or not to take Zavesca together with food, or to temporarily reduce your dose. In some cases the doctor may prescribe anti-diarrhoeal medicines such as loperamide. If your diarrhoea does not respond to these measures, or if you have any other abdominal complaint, consult your doctor. In such case, your doctor may decide to conduct further investigations.

Male patients should use reliable birth control methods during their treatment with Zavesca, and for 3 months after finishing treatment.

Using other medicines

Talk to your doctor if you are using Cerezyme, or other medicines containing imiglucerase, which are sometimes used at the same time as Zavesca. They may lower the amount of Zavesca in your body. Please tell your doctor or pharmacist if you are using, or have recently used, any other medicines, including medicines obtained without prescription.

Taking Zavesca with food and drink
Zavesca can be taken with or without food. You should swallow the whole capsule with a glass of water.

Pregnancy and breast-feeding
You should not use Zavesca if you are pregnant or thinking of becoming pregnant. Your doctor can give you more information. You must use effective birth control while using Zavesca. Do not breast-feed while you are using Zavesca.

Male patients should use reliable birth control methods during their treatment with Zavesca, and for 3 months after finishing treatment.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines
Zavesca may make you feel dizzy. Do not drive or use any tools or machines if you feel dizzy.

How is it used?

Always take Zavesca exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure about any of the instructions.

  • For type 1 Gaucher disease: For adults, the usual dose is one capsule (100 mg) three times a day (morning, afternoon and evening). This means a daily maximum of three capsules (300 mg).
  • For Niemann-Pick type C disease: For adults and adolescents, the usual dose is two capsules (200 mg) three times a day (morning, afternoon and evening). This means a daily maximum of six capsules (600 mg).

If you are less than 12 years old, your doctor will adjust your dose for Niemann-Pick type C disease.

If you have a problem with your kidneys you may receive a lower starting dose. Your doctor may reduce your dose, e.g., to one capsule (100 mg) once or twice a day, if you suffer from diarrhoea when taking Zavesca (see section 4). Your doctor will tell you how long your treatment will last.

To remove the capsule:

1. Separate at perforations

2. Peel back paper at arrows

3. Push product through foil

The Zavesca capsule should be swallowed whole with water.

If you take more Zavesca than you should

If you take more capsules than you were told to, consult your doctor immediately. Zavesca has been used in clinical trials at doses ten times higher than the recommended dose: this caused decreases in white blood cells and other side effects similar to those described in section 4.

If you forget to take Zavesca
Take the next capsule at the usual time. Do not take a double dose to make up for a forgotten dose.

If you stop taking Zavesca
