Details with Side Effects
To minimize CNS depression and possible potentiation, barbiturates, antihistamines, narcotics, hypotensive agents or phenothiazines should be used with caution. Ethyl alcohol should not be used since there may be an Antabuse (disulfiram)-like reaction. Because Matulane (procarbazine) exhibits some monoamine oxidase inhibitory activity, sympathomimetic drugs, tricyclic antide-pressant drugs (eg, amitriptyline HCI, imipramine HCI) and other drugs and foods with known high tyramine content, such as wine, yogurt, ripe cheese and bananas, should be avoided. A further phenomenon of toxicity common to many hydrazine derivatives is hemolysis and the appearance of Heinz-Ehrlich inclusion bodies in erythrocytes.
Teratogenic Effects: Pregnancy Category D. Procarbazine hydrochloride can cause fetal harm when administered to a pregnant woman. While there are no adequate and well-controlled studies with procarbazine hydrochloride in pregnant women, there are case reports of malformations in the offspring of women who were exposed to procarbazine hydrochloride in combination with other antineoplastic agents during pregnancy. Matulane (procarbazine) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant. Procarbazine hydrochloride is teratogenic in the rat when given at doses approximately 4 to 13 times the maximum recommended human therapeutic dose of 6 mg/kg/day.
Nonteratogenic Effects: Procarbazine hydrochloride has not been adequately studied in animals for its effects on peri- and postnatal development. However, neurogenic tumors were noted in the offspring of rats given intravenous injections of 125 mg/kg of procarbazine hydrochloride on day 22 of gestation. Compounds which inhibit DNA, RNA and protein synthesis might be expected to have adverse effects on peri- and postnatal development.
Carcinogenesis, Mutagenesis and Impairment of Fertility
The carcinogenicity of procarbazine hydrochloride in mice, rats and monkeys has been reported in a considerable number of studies. Instances of a second non-lymphoid malignancy, including lung cancer and acute myelocytic leukemia, have been reported in patients with Hodgkin's disease treated with procar-bazine in combination with other chemotherapy and/or radiation. The risks of secondary lung cancer from treatment appear to be multiplied by tobacco use. The International Agency for Research on Cancer (IARC) considers that there is "sufficient evidence" for the human carcinogenicity of procarbazine hydrochlo-ride when it is given in intensive regimens which include other antineoplastic agents but that there is inadequate evidence of carcinogenicity in humans given procarbazine hydrochloride alone.
Procarbazine hydrochloride has been shown to be mutagenic in a variety of bacterial and mammalian test systems.
Impairment of Fertility
Azoospermia and antifertility effects associated with pro-carbazine hydrochloride administration in combination with other chemothera-peutic agents for treating Hodgkin's disease have been reported in human clinical studies. Since these patients received multicombination therapy, it is difficult to determine to what extent procarbazine hydrochloride alone was involved in the male germ-cell damage. The usual Segment I fertility/reproduction studies in laboratory animals have not been carried out with procarbazine hydrochloride. However, compounds which inhibit DNA, RNA and/or protein synthesis might be expected to have adverse effects on gametogenesis. Unscheduled DNA synthesis in the testis of rabbits and decreased fertility in male mice treated with procarbazine hydrochloride have been reported.
Undue toxicity may occur if Matulane (procarbazine) is used in patients with impairment of renal and/or hepatic function. When appropriate, hospitalization for the initial course of treatment should be considered.
If radiation or a chemotherapeutic agent known to have marrow-depressant activity has been used, an interval of one month or longer without such therapy is recommended before starting treatment with Matulane (procarbazine) . The length of this interval may also be determined by evidence of bone marrow recovery based on successive bone marrow studies.
Prompt cessation of therapy is recommended if any one of the following occurs:
Central nervous system signs or symptoms such as paresthesias, neuropathies
Leukopenia (white blood count under 4000).
Thrombocytopenia (platelets under 100,000).
Stomatitis - The first small ulceration or persistent spot soreness around the oral cavity is a signal for cessation of therapy. Diarrhea - Frequent bowel movements or watery stools. Hemorrhage or bleeding tendencies.
Bone marrow depression often occurs 2 to 8 weeks after the start of treatment. If leukopenia occurs, hospitalization of the patient may be needed for appropriate treatment to prevent systemic infection.
Baseline laboratory data should be obtained prior to initiation of therapy. The hematologic status as indicated by hemoglobin, hema-tocrit, white blood count (WBC), differential, reticulocytes and platelets should be monitored closely - at least every 3 or 4 days.

See WARNINGS section.
Pregnancy Category D. See WARNINGS section.
It is not known whether Matulane (procarbazine) is excreted in human milk. Because of the potential for tumorigenicity shown for procarbazine hydrochloride in animal studies, mothers should not nurse while receiving this drug.
Undue toxicity, evidenced by tremors, coma and convulsions, has occurred in a few cases. Dosage, therefore, should be individualized (See DOSAGE AND ADMINISTRATION). Very close clinical monitoring is mandatory.
