What ONCASPAR used for

ONCASPAR contains pegaspargase which is a form of an enzyme called asparaginase. This enzyme breaks down to asparaginase, an important building block in making proteins, without which cells cannot survive. ONCASPAR lowers asparaginase levels in blood cancer cells and stops the cancer from growing. Pegaspargase may sometimes be called pegylated (or "PEG") asparaginase.
ONCASPAR is used to treat leukaemia. It belongs to a group of medicines called antineoplastic or cytotoxic medicines. You may also hear of these being called chemotherapy medicines.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
There is no evidence that it is addictive.
This medicine is available only with a doctor's prescription.
