Procarbazine should be taken only under the supervision of a doctor with experience in the use of chemotherapy medications.
Keep all appointments with your doctor and the laboratory. Your doctor will order laboratory tests before, during and after your treatment to check your body's response to procarbazine.
Why is this medication prescribed?
Procarbazine is used in combination with other medications to treat certain types of Hodgkins disease (types of cancer that begin in a type of white blood cells that normally fights infection). Procarbazine is in a class of medications called alkylating agents. It works by slowing or stopping the growth of cancer cells in your body.
How should this medicine be used?
Procarbazine comes as a capsule to take by mouth. It is usually taken one or more times a day. The length of treatment depends on the types of drugs you are taking, how well your body responds to them, and the type of cancer you have. Take procarbazine at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take procarbazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Your doctor may adjust your dose of procarbazine or stop your treatment for a period of time depending on your response to treatment and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment.
Other uses for this medicine
