What Cromiva is and what it is used for

Cromiva contains the active substance miglustat which belongs to a group of medicines that affect
Cromiva is used to treat mild to moderate type 1 Gaucher disease in adults.
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. Cromiva is only used when a
patient is considered unsuitable for treatment with enzyme replacement therapy.


What you need to know before you take Cromiva

if you are allergic to miglustat or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor or pharmacist before taking Cromiva
- if you suffer from kidney disease
- if you suffer from liver disease
Your doctor will perform the following tests before treatment and during treatment with Cromiva:
- an examination to check the nerves in your arms and legs
- measurement of vitamin B12 levels
- monitoring of blood platelet counts

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 Cromiva. 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 Cromiva (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 such as sucrose (cane sugar), or not to take Cromiva 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 Cromiva, and for 3
months after finishing treatment.
