Alkacel (Melphalan) – Patient Information for Australia
Alkacel contains melphalan, a cancer medicine used in specific situations to slow the growth of certain cancers by damaging cancer cell DNA. This guide explains how Alkacel works, how it is used, what to expect, and important safety considerations. It is written in patient-friendly language for an Australian audience.
Note: Cancer medicines can be complex and your individual treatment plan depends on your diagnosis, other health conditions, and blood test results. Always follow the treatment plan provided by your healthcare team.
Basic product information

What it is: Melphalan is an alkylating agent (a type of chemotherapy). It works by attaching reactive chemical groups to DNA in rapidly dividing cells, which interferes with DNA replication and cell division.
Who it’s for: Alkacel is used for selected blood cancers and related conditions, typically under oncology care with regular monitoring.
Mechanism of action (how Alkacel works)
Melphalan is an alkylating chemotherapy. After it is absorbed, it forms highly reactive compounds that can attach to DNA. This DNA damage prevents cancer cells from copying themselves and from repairing the damage effectively.
- Primary effect: DNA cross-linking and misrepair in rapidly dividing cells.
- Result: Slower tumour growth and reduced cancer cell survival.
- Why monitoring matters: Because it affects cell division broadly, it can also reduce healthy blood cell production.
Pharmacokinetics (absorption, distribution, metabolism, elimination)
Pharmacokinetics describes how the body handles a medicine. With melphalan, key points include:
- Absorption: Oral absorption occurs through the gastrointestinal tract, with variability between individuals.
- Distribution: Melphalan distributes into body tissues, including tumour sites.
- Metabolism/activation: Melphalan undergoes chemical transformation in the body into active forms that can damage DNA.
- Elimination: The drug and its metabolites are cleared from the body primarily through renal (kidney) and other metabolic pathways.
Clinical implication: Because melphalan exposure can vary, your doctor may adjust timing, dose, or supportive care based on blood counts and kidney function.
Typical use in Australia (indications)
In clinical practice, melphalan (including Alkacel) is used for certain cancers, commonly:
- Multiple myeloma: Often used as part of chemotherapy regimens, including conditioning approaches in some transplant-related settings.
- Other haematologic cancers: Depending on the individual case, it may be used for certain related blood disorders where melphalan-based therapy is appropriate.
Important: The exact indication, schedule, and dose can vary widely. Your healthcare team will choose a regimen matched to your diagnosis and treatment goals.
How and when Alkacel is taken (timing)
Alkacel may be given as an oral chemotherapy course. Timing and frequency depend on your regimen. The following general principles apply for many melphalan schedules:
- Take at the same time each day on the prescribed days.
- Follow cycle instructions exactly (for example, daily dosing for a set number of days, then a rest period).
- Use supportive medicines as directed (e.g., anti-nausea treatment) to improve comfort and adherence.
Practical tip: Consider setting reminders and keeping a treatment diary that includes blood test dates and any dose adjustments.
Food interactions
Food can affect how chemotherapy is absorbed. With melphalan, taking it with or without food can influence blood levels. Because absorption can vary by formulation and individual factors, your healthcare team may give specific instructions.
General guidance (commonly used with oral melphalan):
- Ask for your specific instructions about whether to take Alkacel on an empty stomach or with food.
- Be consistent once you receive a recommendation (do not change the way you take it day to day unless your team instructs you).
Report side effects: If nausea, vomiting, or diarrhoea occurs, tell your doctor. Vomiting shortly after taking a dose may require advice about whether to repeat it.
Alcohol and medicine interactions
Alcohol can worsen some chemotherapy side effects (such as nausea, fatigue, dizziness, dehydration, and liver stress) and may also interact with supportive medications.
- Alcohol: It’s generally advisable to avoid or minimise alcohol during chemotherapy unless your healthcare team approves.
- Other medicines: Many medicines can interact indirectly by increasing nausea risk, affecting liver enzymes, or altering blood counts.
Always check before starting or stopping:
- Over-the-counter medicines (e.g., pain relievers, cold/flu products)
- Herbal products (e.g., St John’s wort)
- Supplements (including “natural” products)
Why it matters: Some interactions may require dose changes or extra monitoring to keep you safe.
Dosing overview (individualised)
Dose depends on: your cancer type, regimen, body size, kidney function, blood counts, and other treatment history. Alkacel dosing may be scheduled in cycles with breaks to allow recovery.
Common dosing concepts:
- Cycle-based therapy: A number of days of treatment followed by a rest period.
- Blood count monitoring: Your dose may be modified based on your neutrophil and platelet levels.
- Renal function considerations: Dose may require adjustment if kidney function is reduced.
Do not change your dose: Chemotherapy dosing is carefully calculated. If you miss a dose, contact your healthcare team promptly for advice rather than trying to “make up” the dose yourself.
Safety profile: what to watch for
Like other chemotherapy medicines, Alkacel can cause side effects. Some are predictable and manageable with supportive care, while others require urgent medical attention.
Common side effects
- Low blood counts (myelosuppression): Increased risk of infections and bleeding
- Nausea and vomiting
- Diarrhoea or constipation
- Fatigue
- Loss of appetite
- Hair thinning (may vary by regimen)
- Oral sores (mucositis)
Serious risks – seek urgent medical help
Contact your healthcare team urgently or seek emergency care if you experience:
- Fever (especially in people with low white blood cells)
- Signs of infection such as chills, persistent cough, burning when urinating
- Unusual bruising, bleeding gums, black/tarry stools, or blood in urine
- Severe or persistent diarrhoea or vomiting causing dehydration
- Shortness of breath or chest pain
- Severe allergic-type symptoms such as swelling of face/lips or difficulty breathing
Long-term safety considerations
Chemotherapy can carry longer-term risks depending on cumulative dose and treatment history. Your oncologist will review your individual risk profile, which may include concerns such as:
- Risk of therapy-related complications (varies by regimen)
- Fertility effects
- Second cancer risk (rare, but discussed as part of cancer therapy planning)
Fertility and pregnancy: Alkylating agents may affect fertility. If you are planning a pregnancy or could become pregnant, discuss contraception and fertility preservation options with your healthcare team before treatment.
Practical use tips (making treatment safer and easier)
- Keep track of blood tests: Attend all scheduled monitoring appointments.
- Use anti-nausea medicines as prescribed: They are often more effective when started early.
- Stay hydrated: Unless your team advises fluid restriction, adequate fluids can help reduce dehydration risk during nausea/diarrhoea.
- Oral care: Use a soft toothbrush and consider alcohol-free mouth rinses if recommended.
- Infection prevention: Practise good hand hygiene, avoid close contact with people who are unwell, and report fever immediately.
- Bleeding precautions: Use gentle activities and avoid unnecessary injury; inform your team before dental procedures or new medications that affect clotting.
- Medication handling: Follow safety instructions for chemotherapy tablets/packaging (e.g., avoid crushing unless directed; handle carefully to minimise skin contact).
When to contact your team: If side effects stop you from taking your medicine as scheduled, your doctor can often adjust supportive care or modify the regimen.
Alternative options (depending on the cancer type and regimen)
“Alternative” means different medicines or different combinations used to treat similar cancers. Alternatives depend on your diagnosis, stage, prior therapy, and overall health.
Your healthcare team may consider options such as:
- Other chemotherapy agents used alone or in combination
- Targeted therapies (medicines that act on specific cancer pathways)
- Immunotherapies (where appropriate)
- Supportive treatments to manage symptoms and complications (e.g., antiemetics, growth factor support in some settings)
- Radiotherapy or stem cell transplant approaches in selected patients (for certain regimens and clinical indications)
Decision-making: Your oncologist will explain why melphalan is chosen in your case and what alternatives may be appropriate if adjustments are needed.
