Leukeran (Chlorambucil) — Patient Information (Australia)
Leukeran is a cancer medicine containing chlorambucil. It belongs to a group of medicines known as alkylating agents—a type of chemotherapy designed to interfere with the growth of rapidly dividing cells.
This page is written to be patient-friendly and provide practical, general information. It does not replace advice from your treating healthcare professional. Cancer treatment is individual; your schedule and dose may differ from general descriptions.

How Leukeran Works (Mechanism of Action)
Chlorambucil works by damaging the DNA inside cancer cells. It does this through an “alkylation” process, where reactive drug components attach to DNA molecules. This interferes with the cancer cell’s ability to copy its genetic material and divide.
Because chemotherapy targets rapidly dividing cells, it can also affect some healthy tissues—especially cells involved in blood production and the lining of the mouth or gut. This explains why monitoring and supportive care are important.
Pharmacokinetics (How the Body Handles It)
Pharmacokinetics describes what the body does to the medicine (absorption, distribution, metabolism, and elimination). In broad terms:
- Absorption: Chlorambucil is taken by mouth and absorbed from the digestive tract.
- Metabolism: It is metabolised in the body (primarily involving liver pathways) into active and inactive forms.
- Distribution: The drug and its metabolites distribute through the body, reaching tissues where cancer cells may be present.
- Elimination: The metabolites are eliminated mainly via the kidneys and other metabolic routes.
Your clinician may adjust treatment based on factors like liver function, kidney function, and your blood counts.
Typical Uses and Indications
Leukeran is used for certain cancers, most commonly some blood cancers. The exact indication depends on your diagnosis, previous treatment history, and overall health.
Common categories where chlorambucil has been used include:
- Chronic lymphocytic leukaemia (CLL)
- Some types of indolent (slow-growing) non-Hodgkin lymphoma
Important note: Modern treatment plans for lymphoid cancers often include newer targeted therapies and combination regimens. Leukeran may still be considered in specific circumstances depending on availability, patient factors, and specialist guidance.
Timing and How It’s Usually Taken
Leukeran is taken as oral tablets. The schedule can vary depending on the treatment plan and your blood test results.
Common timing concepts
- Consistent schedule: Take the medicine at the times your healthcare professional specifies.
- Cycle-based or continuous approaches: Some regimens are short “pulses” repeated in cycles; others involve a steady schedule with adjustments.
- Blood-count–guided changes: Dose and duration may be adjusted based on how your blood counts respond.
Because chlorambucil can lower white blood cell counts and platelets, your clinician may delay or modify doses if your blood results are too low.
Food Interactions
Food interactions can influence how medicines are absorbed. For chlorambucil, the general approach is:
- Follow your local instructions: Your prescribing information or pharmacist’s advice should guide whether to take it with food.
- Consistency helps: If it can be taken with or without food, many clinicians advise taking it the same way each time to maintain consistent absorption.
- Manage nausea if needed: If you experience nausea, taking the dose with a light meal may help (unless your clinician advises otherwise).
If you are unsure, ask your pharmacist for specific guidance for your prescribed regimen.
Alcohol and Medicine Interactions
Alcohol: Alcohol may worsen side effects such as fatigue, nausea, and liver stress. While moderate alcohol may not directly “interact” with chlorambucil in the usual sense, it can still be risky during chemotherapy.
- Recommendation: Limit or avoid alcohol unless your healthcare team says it’s safe for you.
- Tell your clinician: Mention any regular alcohol use, history of liver disease, or heavy drinking.
Medicine interactions: Interactions depend on what else you take. Tell your healthcare professional or pharmacist about:
- Other medicines that affect blood counts (e.g., certain immunosuppressants)
- Other chemotherapy or radiotherapy
- Medicines that can stress the liver
- Vaccines: live vaccines may be less suitable during chemotherapy
- Medicines used for infections, including antifungals and antivirals
- Herbal products (e.g., St John’s wort) which can affect metabolism
Your healthcare team can check for drug–drug and drug–disease interactions before and during therapy.
Dosing (General Information)
Exact dosing for Leukeran varies by diagnosis, regimen type, age, kidney and liver function, and blood counts. Your doctor will determine a personalized dose.
Typical general patterns in practice may include:
- Fixed dose schedules on certain days
- Adjustments based on blood tests (white blood cell and platelet counts)
- Modified dosing in the elderly or in those with reduced organ function
Do not change your dose unless your clinician instructs you to. If you miss a dose, ask your healthcare professional or pharmacist for guidance—do not double up.
Safety Profile and Side Effects
Like all chemotherapy medicines, chlorambucil can cause side effects. Some effects may be temporary; others may require medical management.
Common or clinically important side effects
- Low blood counts (neutropenia, anaemia, thrombocytopenia)
- Increased infection risk when white cells are low
- Fatigue and weakness
- Nausea, vomiting, or loss of appetite
- Diarrhoea or constipation
- Hair thinning (less common than with some other chemo, but can occur)
- Skin reactions such as rash or irritation (less common)
- Oral sores (mucositis)
Serious risks (seek urgent advice)
- Fever or signs of infection: a fever can be a medical emergency during chemotherapy.
- Unusual bruising or bleeding: may indicate low platelets.
- Severe shortness of breath or chest pain: needs urgent assessment.
- Severe allergic-type reactions: swelling, difficulty breathing, or widespread rash require emergency care.
Longer-term considerations
Because chlorambucil affects DNA, there can be longer-term risks associated with some alkylating agents. Your oncology team can discuss these risks in the context of your cancer type and treatment goals.
Practical Use Tips (Patient-Friendly)
- Plan for blood tests: Keep appointments for full blood counts and other monitoring. These results guide safe dosing.
- Infection prevention: Practice good hand hygiene, avoid close contact with people who are sick, and promptly report fever.
- Skin and mouth care: Use gentle mouth care, and report mouth ulcers early.
- Hydration and nutrition: Drink enough fluids and aim for calorie/protein intake where possible.
- Medication handling: Chemotherapy agents are cytotoxic. If handling tablets directly is required, follow your pharmacist’s instructions regarding protection and hygiene.
- Pregnancy and contraception: Chlorambucil can affect fertility and may harm an unborn baby. Discuss contraception and family planning with your clinician before starting.
- Report other medical conditions: Inform your healthcare team about liver disease, kidney problems, or prior chemo/radiotherapy.
When to Contact Your Healthcare Team Immediately
Contact your healthcare provider or seek urgent care if you have:
- Fever (especially if you feel unwell or have chills)
- Signs of infection (e.g., sore throat, burning urine, persistent cough)
- Unusual bleeding (nosebleeds, gum bleeding, blood in urine/stool) or bruising
- Severe or persistent vomiting or inability to keep fluids down
- Severe diarrhoea
- Severe weakness, dizziness, or fainting
- Any sudden allergic reaction symptoms
Alternative Options
For blood cancers like CLL and indolent non-Hodgkin lymphoma, treatment choices may include:
- Targeted therapies (e.g., agents that block specific cancer pathways)
- Immunotherapies (monoclonal antibodies or combination regimens)
- Other chemotherapy agents depending on disease characteristics
- Supportive care strategies (for example, treatments to manage low blood counts)
The “best” option depends on the specific subtype of your cancer, genetic factors, prior treatments, symptoms, and overall health. Your oncology team can explain why Leukeran is selected (or not) for your situation.
