About Leukeran
Leukeran - also known as Generic Leukeran (chlorambucil) - is an oral chemotherapy pill used primarily in the treatment of certain blood cancers such as chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma. As an alkylating agent, it works by attaching to DNA strands in rapidly dividing cells, thereby hindering their ability to multiply. In Singapore, this medication is prescription-only and is typically prescribed by oncologists as part of a broader therapeutic regimen. Off-label use is uncommon, but some clinicians explore it in niche hematologic conditions under strict supervision.
What is Generic Leukeran (chlorambucil)?
Generic Leukeran (chlorambucil) belongs to the class of alkylating agents, a group of drugs that interfere with DNA replication. The Singapore Health Sciences Authority (HSA) approved chlorambucil for adult patients with chronic lymphocytic leukemia and certain types of lymphoma. It is supplied as a solid oral tablet, commonly 2 mg, and is marketed by several licensed pharmaceutical firms following rigorous quality-control standards.
How Leukeran Works
Chlorambucil exerts its anti-cancer effect through alkylation of the guanine bases in DNA. This forms covalent cross-links that prevent the double helix from unwinding during replication, ultimately triggering cell-cycle arrest and apoptosis in rapidly proliferating malignant cells. After oral ingestion, the drug is absorbed from the gastrointestinal tract with a bioavailability of roughly 70 %. Peak plasma concentrations appear within 2 hours, and the compound has a relatively long elimination half-life of 5-6 days, allowing once-daily dosing. Metabolism occurs primarily in the liver via oxidative pathways, and renal excretion eliminates the inactive metabolites.
Why Leukeran Is Used for Cancer Treatment
- Chronic lymphocytic leukemia (CLL): The drug’s ability to cross-link DNA directly targets the clonal B-cell population characteristic of CLL, leading to prolonged remission in many patients.
- Non-Hodgkin lymphoma (NHL): In low-grade NHL, chlorambucil slows disease progression and reduces tumor burden, often serving as a first-line option for older or frail patients who cannot tolerate more aggressive regimens.
- Waldenström macroglobulinemia: Although not formally approved, clinical experience shows benefits in disease control, especially when combined with rituximab.
- Guideline position: The National Comprehensive Cancer Network (NCCN) lists chlorobucil as a recommended agent for patients with CLL who are either treatment-naïve or have relapsed after other therapies. Its long half-life and oral route make it a convenient alternative to intravenous alkylators.
Off-Label and Investigational Uses of Leukeran
Small pilot studies have examined chlorambucil in autoimmune hemolytic anemia and certain solid-tumor protocols, but robust evidence is lacking. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Leukeran Right for You?
Leukeran is generally suitable for adult patients with confirmed indications who can tolerate oral chemotherapy and have adequate liver and kidney function. Elderly patients often benefit from its oral administration, yet dose adjustments may be necessary for those with hepatic impairment. Pregnancy and lactation are contraindicated because the drug can cross the placenta and appear in breast milk, posing fetal or infant toxicity. Patients with a history of severe bone-marrow suppression should discuss alternative options, as leukopenia and anemia are common dose-limiting toxicities.
Taking Leukeran Effectively
- Timing: Take the tablet at the same time each day, preferably with a light meal to minimize gastrointestinal irritation.
- Food interactions: High-fat meals can slightly delay absorption but do not significantly affect overall exposure.
- Missed dose: If you forget a dose, take it as soon as you remember unless it is within 12 hours of the next scheduled dose; in that case, skip the missed one and resume the regular schedule.
- Travel: Carry a written prescription and keep the medication in its original container to avoid customs delays.
- Adherence: Set daily reminders; consistent dosing is essential because the drug’s long half-life creates steady plasma levels only with regular intake.
Understanding Side Effects and How to Manage Them
- Myelosuppression (low blood counts): Chlorambucil’s DNA cross-linking also impacts normal bone-marrow cells. Routine complete blood counts (CBC) every 2-4 weeks allow early detection. If neutrophil counts fall below 1.5 × 10⁹/L, dose reduction or temporary interruption is advised.
- Nausea & vomiting: Taking the tablet with food or a small glass of milk often reduces discomfort. Over-the-counter antiemetics such as ondansetron can be prescribed if symptoms persist.
- Alopecia (hair loss): Typically mild; using gentle hair care products and avoiding heat styling can lessen breakage.
- Secondary malignancies: Long-term alkylator exposure carries a small risk of therapy-related myelodysplastic syndromes; regular monitoring and risk-benefit discussions are essential.
- When to seek care: Persistent fever, unexplained bruising, or sudden shortness of breath should prompt immediate medical evaluation.

Frequently Asked Questions
-
What should I do if I develop a low white-blood-cell count while on Leukeran? Monitor CBC results closely; your oncologist may pause treatment or lower the dose until counts recover.
-
Can I take Leukeran with other chemotherapy agents? Chlorambucil is often combined with monoclonal antibodies such as rituximab; however, combinations should only be prescribed by a specialist familiar with drug interactions.
-
Is it safe to drink alcohol while taking Leukeran? Moderate alcohol intake is not contraindicated, but excessive consumption can worsen liver toxicity and increase myelosuppression risk.
-
How long will treatment with Leukeran last? Duration varies; some patients take it continuously until disease progression, while others use a fixed-cycle regimen based on response criteria.
-
Will my insurance cover Leukeran purchased online? Coverage depends on individual policy terms; we recommend checking with your insurer before ordering.
-
Are there dietary restrictions while on this medication? No specific restrictions, but maintaining a balanced diet supports bone-marrow recovery and overall health.
-
What is the difference between Leukeran and other alkylating agents like cyclophosphamide? Chlorambucil has a longer half-life and is administered orally, whereas cyclophosphamide is often given intravenously and has a different toxicity profile.
-
Can I store Leukeran at home? Keep tablets in a cool, dry place away from direct sunlight; do not freeze. Store out of reach of children.
-
Is generic Leukeran as effective as the branded version? Yes. Generic formulations contain the same active ingredient, dosage strength, and are bioequivalent, offering the same therapeutic outcomes at a lower cost.
-
What should I expect during the first weeks of therapy? Initial side effects may include mild nausea, transient fatigue, and occasional low blood counts; most patients adapt within a month with appropriate monitoring.
