What is Erwinase?
Erwinase is an injectable medicine containing asparaginase Erwinia chrysanthemi. Asparaginase is a cancer medication that interferes with the growth and spread of cancer cells in the body.
Erwinase works by lowering the levels of asparagine in your body, a substance the cancer cells need to survive.
Erwinase is used to treat acute lymphoblastic acute lymphoblastic leukemia (ALL) in adults and children at least at least 4 months old.
