Molecule Description
Procarbazine anti-cancer medicine. It belongs to a class of medicines called antineoplastic agents. It is indicated, along with other anticancer medicines, for certain patients with Hodgkin's disease. It contains procarbazine. It belongs to a class of medicines called antineoplastic alkylating agents. It works by inhibiting protein, RNA, and DNA synthesis, thereby interfering with the growth and multiplication of rapidly dividing cells.
Procarbazine can cause bone marrow suppression, leading to low blood cell counts, increased risk of infection, anaemia, and bleeding. Your doctor will monitor blood counts regularly. Report fever, chills, sore throat, unusual bleeding or bruising, or severe tiredness promptly.
Take Procarbazine exactly as prescribed, at the same time each day, and do not change or stop the dose without medical advice. Report persistent mouth ulcers or soreness, as treatment may need adjustment.
Common side effects include nausea, vomiting, loss of appetite, dry mouth, constipation, and fatigue. Serious effects may include liver problems, lung inflammation, and neurological symptoms such as numbness, tingling, confusion, or unsteadiness.
Tell your doctor about any liver, kidney, blood, or other serious health problems. Avoid pregnancy and breastfeeding during treatment as advised by your doctor. Avoid driving if you experience dizziness, confusion, or weakness. Avoid alcohol and tyramine-rich foods such as aged cheese and certain fermented foods, as advised during treatment.

Mode of Action
How Does It Work?
Procarbazine belongs to hydrazine derivatives. It is broken down mainly by the liver and kidneys into active by-products that disrupt the cellular machinery used to build proteins and copy DNA and RNA. By disrupting protein, RNA, and DNA synthesis and damaging DNA, Procarbazine interferes with the growth and multiplication of rapidly dividing cells.
Interactions
Interactions with other medicines
- Alcohol: Procarbazine may cause a disulfiram-like reaction with alcohol. Avoid alcohol completely during treatment.
- Sympathomimetics, tricyclic antidepressants, and tyramine-rich foods: Procarbazine has MAO-inhibitory activity and may cause dangerous increases in blood pressure or other serious reactions. Avoid these combinations as advised by your doctor.
- Other chemotherapy or radiotherapy: May increase the risk of severe bone marrow suppression when given with Procarbazine.
- CNS depressants: Medicines such as barbiturates, sedating antihistamines, opioids, and phenothiazines may increase drowsiness and sedation.
- Inform your doctor about all prescription and OTC medicines, vitamins, supplements, and herbal products you take before and during treatment.
Interactions with food items
Procarbazine capsules can be taken with or without food. Avoid high-tyramine foods like wine, aged cheese, yogurt, and bananas during treatment to prevent serious blood pressure reactions. Alcohol, including in foods or medicines, must be avoided to prevent severe reactions.
Dosage
Overdose
An overdose of Procarbazine may cause severe nausea, vomiting, inflammation of the bowel, diarrhoea, low blood pressure, tremors, seizures, and loss of consciousness (coma). There is no specific antidote for Procarbazine overdose. If an overdose is suspected, seek urgent medical attention immediately or go to the nearest hospital emergency department.
