Generic Name: Cyclophosphamide
Product Name: Endoxan
Endoxan is a drug used to treat various cancerous dieases (breast and ovarian cancers, and leukaemia), disorders of the immune system (such as systemic lupus erythematosus and vasculitis). Endoxan is also used to prevent transplant rejection in some instances. If you are unsure why Endoxan has been prescribed for you, contact your doctor.
Endoxan is a type of drug known as a cytotoxic agent. It works by killing rapidly dividing cells, which make it particularly useful in the treatment of certain cancers and disorders of the immune system. Unfortunately, Endoxan can also target normal rapidly dividing cells in the body, which can result in unwanted side effects such as nausea and vomiting, and hair loss.
