Procarbazine is an alkylating chemotherapy drug used along with other chemotherapy drugs to treat Hodgkin's disease (also known as Hodgkin's lymphoma). It works by preventing cancer cells from growing and from creating new cancer cells. Because procarbazine also affects the growth of normal body cells, you will most likely experience side effects while using this drug.
Procarbazine also acts as a monoamine oxidase inhibitor. (See also Drug Interactions for cautions regarding use of procarbazine with other drugs and the need to limit the amount of tyramine in your diet.)
