What ZAVESCA is used for

ZAVESCA is a medicine that is used to treat mild to moderate Type 1 Gaucher disease in adults and it is also used to treat Niemann-Pick type C (NP-C) disease in children, adolescents and adults.
Type 1 Gaucher disease is an inherited disease that you get from both of your parents. People with Type 1 Gaucher disease are partially missing an enzyme that breaks down a chemical in the body called glucosylceramide. Too much glucosylceramide causes an increase in the size of the liver and spleen. It also causes bone disease and changes in the blood.
ZAVESCA reduces the formation of glucosylceramide to a level the partially missing enzyme can cope with.
You may be prescribed ZAVESCA if your doctor decides other treatments for this disease are not right for you.
Niemann-Pick disease is an inherited disease that you get from both parents. If you have NP-C, fats (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.
Your doctor may have prescribed ZAVESCA for another reason. Ask your doctor if you have any questions about why ZAVESCA has been prescribed for you.

Before you take ZAVESCA

Do not take ZAVESCA if you are pregnant or planning to become pregnant.
ZAVESCA may harm your baby. You must use effective birth control while you are taking ZAVESCA.
Do not take ZAVESCA if you are breastfeeding.
It is not known if this medicine passes into breast milk and if it can harm your baby.
ZAVESCA may harm sperm.
All men should use effective birth control while taking this medicine and for 3 months after they stop taking it.
Do not take ZAVESCA if you suffer from severe kidney disease.
Do not take it after the expiry date (EXP) printed on the pack.
If you take this medicine after the expiry date has passed it may not work as well.
Do not take it if the packaging is torn or shows signs of tampering.

Before you start to take it

Tell your doctor if you are pregnant or planning to become pregnant.
Tell your doctor if you are breastfeeding or are planning to breastfeed.
Tell your doctor if you have or have had any medical conditions especially the following:
kidney disease
liver disease
If you have not told your doctor about any of the above, tell them before you take ZAVESCA.
Your doctor may perform the following tests before treatment and during treatment with ZAVESCA:
an examination to check the nerves in your arms and legs
a test of your memory and thinking ability
blood test to check your platelet count
measurement of vitamin B12 levels (for GD-1 only)
if you are a child or adolescent with NP-C your doctor will also check measurements of your growth
The reason these tests are done is that some patients have had tingling or numbness in the hands and feet, or memory and thinking problems, while taking ZAVESCA. The tests will help your doctor decide whether these effects are due to existing conditions, or due to side effects of ZAVESCA.

Taking other medicines

Tell your doctor if you are taking any other medicines including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines may be affected by ZAVESCA or may affect how well it works.
