The more Cytoxan you take and the longer you take it, the greater your risk of developing cancer, even later in life. Leukemia and bladder cancer are the most common form of cancer developed in patients taking Cytoxan, so your doctor should perform urine tests regularly.

Cytoxan can interact with certain drugs, so be sure to tell your doctor about any medications you are taking, either prescription or over-the-counter.

The following drugs can interact with Cytoxan: the gout medication allopurinol Aloprim, Zyloprimphenobarbital Solfotonwarfarin Coumadinthiazide diuretics, such as hydrochlorothiazide, and some psychiatric medications.
