Leukeran is a brand-name medication that contains the active ingredient chlorambucil. Chlorambucil belongs to a class of drugs known as alkylating agents and is used as an oncology support therapy. In Hong Kong, Leukeran is available only by prescription and is regulated by the Department of Health and the Pharmacy and Poisons Board. The medication is supplied as oral pill tablets in two strengths: 2 mg and 5 mg.
Chlorambucil exerts its anticancer effect by attaching an alkyl group to DNA strands within rapidly dividing cells. This alkylation leads to cross-linking of DNA strands, which interferes with DNA replication and transcription. When cancer cells cannot properly duplicate their genetic material, they undergo programmed cell death (apoptosis).
Key pharmacologic features:
Leukeran (chlorambucil) is approved in Hong Kong for the following indications:
These uses reflect regulatory approvals based on clinical trial data and expert consensus. The medication is generally prescribed for adult patients whose disease characteristics meet the criteria outlined in the product’s official label.
If any of the above conditions apply, a healthcare professional will determine whether Leukeran is appropriate or if alternative therapies should be considered.
Patients should seek immediate medical attention for unexplained fever, easy bruising, persistent bleeding, or severe abdominal pain.
If you are taking other prescription or over-the-counter medicines, inform your healthcare provider before starting Leukeran.
Regular follow-up with a hematology/oncology specialist is essential to balance therapeutic benefit against potential toxicity.

Leukeran may be combined with other agents, but the risk of overlapping bone-marrow toxicity is higher. Your oncologist will assess the safety of any combination and adjust dosing or monitoring accordingly.
Fever can signal infection due to neutropenia. Contact your healthcare provider promptly; they may order blood tests and start antibiotics if an infection is suspected.
Chlorambucil is available as a generic tablet in various strengths. Both brand-name and generic formulations contain the same active ingredient, but you should verify equivalence with your pharmacist.
Food does not significantly alter chlorambucil absorption. Taking the tablet with water, with or without meals, is acceptable; consistency helps maintain steady drug levels.
Mild hair thinning may occur, but complete alopecia is uncommon with chlorambucil compared with some other chemotherapy agents. Hair loss is usually reversible after discontinuation.
Carry the medication in its original container, with a copy of the prescription. Verify that airport security permits the tablets, and keep them in your carry-on luggage to avoid temperature extremes.
A complete blood count (CBC) is essential before each dose to ensure adequate white-cell and platelet counts. Liver and kidney function tests are performed periodically to guide dose adjustments.
Patients with active hepatitis should be evaluated carefully, as liver impairment can increase drug toxicity. Your doctor may monitor liver enzymes more frequently or choose an alternative therapy.
Clinical improvement may be observed after several weeks to months of therapy, depending on disease burden and individual response. Ongoing monitoring helps determine treatment effectiveness.
