For the Consumer
Applies to procarbazine: oral capsule
Oral route (Capsule)
It is recommended that procarbazine hydrochloride be given only by or under the supervision of a physician experienced in the use of potent antineoplastic drugs. Adequate clinical and laboratory facilities should be available to patients for proper monitoring of treatment.
Along with their needed effects, medicines like procarbazine can sometimes cause unwanted effects such as blood problems, loss of hair, high blood pressure reactions, and other side effects. These and others are described below. Also, because of the way these medicines act on the body, there is a chance that they might cause other unwanted effects that may not occur until months or years after the medicine is used. These delayed effects may include certain types of cancer, such as leukemia. Discuss these possible effects with your doctor.
Although not all of these side effects may occur, if they do occur they may need medical attention.
