Common Use

Chlorambucil is an oral chemotherapy medication used to treat certain cancers, primarily chronic lymphocytic leukemia (CLL), Hodgkin's disease, and some types of non-Hodgkin lymphomas. It belongs to a class of drugs called alkylating agents, which work by interfering with DNA replication in cancer cells, preventing their growth and division. Chlorambucil is often used when other treatments are unsuitable or as part of a combination therapy. It may also be used off-label for autoimmune conditions like nephrotic syndrome.

Dosage and Direction

Chlorambucil is taken by mouth, usually once daily, or as prescribed by a doctor. Dosage depends on the type of cancer, patient's weight, blood cell counts, and treatment response. It's important to take it exactly as prescribed - do not increase or skip doses. Handle the tablets carefully and wash your hands after contact.

Precautions

Inform your doctor if you have liver disease, infections, or a history of seizures before starting treatment. This drug may suppress bone marrow function, so regular blood tests are essential during therapy. Avoid contact with people who are sick, as chlorambucil can weaken your immune system. Use effective contraception during and after treatment, as the drug may harm a developing fetus.

Contraindications

Chlorambucil is contraindicated in patients with hypersensitivity to the drug or other alkylating agents. It should not be used in those with severely suppressed bone marrow function unless absolutely necessary. Use during pregnancy or breastfeeding is not recommended due to potential harm to the child. Vaccination with live vaccines should be avoided during treatment.

Possible Side Effects

Common side effects include nausea, vomiting, mouth sores, fatigue, and low blood counts. More serious reactions may include seizures, liver dysfunction, secondary cancers, or severe allergic reactions. Long-term use increases the risk of bone marrow suppression and infertility. Report any persistent fever, unusual bruising, or neurological symptoms immediately.

Drug Interactions

Chlorambucil may interact with other chemotherapy agents, immunosuppressants, or radiation therapy, increasing toxicity. It can also interact with drugs that affect bone marrow or the liver. Avoid using live vaccines during treatment, as your immune response may be compromised. Always inform your doctor about all medications and supplements you are taking.

Missed Dose

If a dose is missed, take it as soon as you remember unless it's near the time of the next dose. In that case, skip the missed dose - do not double up. Inform your healthcare provider if multiple doses are missed. Regular dosing is critical for effective cancer treatment.

Overdose

Overdose symptoms may include severe nausea, vomiting, bleeding, infection, or seizures. Chlorambucil overdose can result in dangerous suppression of bone marrow. Immediate medical intervention is required in such cases. There is no specific antidote; treatment is supportive.

Storage

Store chlorambucil in the refrigerator between 2-8°C (36-46°F), in its original container. Keep it tightly closed, away from light and out of reach of children. Do not freeze or store in the bathroom. Handle unused or expired tablets according to local hazardous waste guidelines.
