Alkacel (Melphalan) – Patient Information Guide (Australia)

Alkacel contains melphalan, a cancer medicine used to treat certain blood cancers and cancers of the skin and soft tissues. This guide explains what Alkacel is, how it works, how it is used, important safety information, and practical tips to help you understand your treatment.

Always follow the instructions given by your treating oncology team. Treatment plans differ depending on the diagnosis, cancer stage, and your medical history.

Key Product Information

Note: Alkacel is a specialised medicine. Availability, presentation, and the exact regimen may vary by hospital and protocol in Australia.

What Alkacel (Melphalan) Is Used For

Melphalan is used mainly for cancers that affect the blood and bone marrow, including:

• Multiple myeloma (in selected patients, often as part of combination treatment strategies)
• Certain plasma cell disorders as directed by oncology specialists
• Some cancers of the skin and localised tumours in selected circumstances

Your oncologist will determine whether melphalan is appropriate based on your diagnosis, prior treatments, kidney function, overall health, and planned treatment approach.

How Alkacel Works (Mechanism of Action)

Melphalan belongs to the group of medicines called alkylating agents. It works by:

• Attaching reactive chemical groups to DNA inside cancer cells
• Causing DNA damage that prevents cancer cells from dividing
• Leading to cell death (especially in rapidly dividing cells)

While melphalan targets cancer cells, it can also affect healthy cells that divide quickly, such as bone marrow cells and cells of the gut. This is why blood counts may drop and why infections and digestive side effects can occur.

Pharmacokinetics (How the Body Handles Melphalan)

“Pharmacokinetics” describes what the body does to a drug over time. Key points include:

• Absorption: After administration, melphalan is absorbed into the bloodstream. Absorption can be affected by food and gastrointestinal conditions.
• Distribution: It distributes to tissues, including areas affected by cancer.
• Metabolism: Melphalan is processed within the body through chemical transformation pathways.
• Elimination: The medicine and its breakdown products are eliminated primarily through renal and other body processes.

In clinical practice, kidney function and overall health can influence dosing and the risk of side effects, so your team will monitor blood results closely.

Typical Timing and Treatment Schedule

Alkacel dosing schedules vary widely depending on the specific cancer type and whether it is used as part of a combination regimen. Your prescription instructions (for example, number of days in a cycle) are tailored to you.

Common practical timing considerations include:

• Follow cycle dates exactly: Chemotherapy cycles are planned around blood count recovery.
• Regular blood tests: Monitoring often occurs before each cycle and at intervals during therapy.
• Plan around clinic visits: You may need extra appointments if counts drop or side effects occur.

If you miss a dose or a scheduled day, contact your oncology team for advice rather than restarting on your own.

Food Interactions: Important Guidance

Food can affect how much melphalan enters your system. For many oral chemotherapy regimens, avoiding or timing meals is essential. Your treating team will provide specific instructions for your formulation and regimen.

General patient-friendly guidance:

• Take medicine exactly as instructed regarding timing relative to meals.
• Do not change your eating pattern (for example, fasting or restarting meals) without discussing with your team.
• Tell your team if you have nausea, vomiting, diarrhoea, or swallowing difficulties, as these can affect absorption and safety.

Because dietary effects can differ by formulation and protocol, always use the directions from your medication label and your oncology team.

Alcohol Interactions

Alcohol may worsen some chemotherapy side effects, such as:

• Nausea and vomiting
• Dizziness and fatigue
• Dehydration, which can affect kidney function
• Increased risk of liver-related complications (where applicable)

For many people, it is safest to avoid or strictly limit alcohol during treatment unless your oncology team advises otherwise. If you drink alcohol, discuss the amount and frequency with your doctor or pharmacist.

Medicine Interactions (What to Check)

Alkacel (melphalan) can interact with other medicines, potentially changing effectiveness or increasing side effects. Interactions are possible through effects on bone marrow, infection risk, gastrointestinal effects, or organ function.

Tell your healthcare team if you use any of the following:

• Other chemotherapy or radiation therapy
• Medicines that suppress the immune system
• Live vaccines (often avoided during active cancer therapy)
• Medicines that affect the gastrointestinal tract (for example, severe anti-nausea regimens or therapies causing diarrhoea/constipation)
• Antibiotics, antifungals, antivirals (important if you are prone to infections)
• Medicines that affect kidney function or hydration status

Also include over-the-counter medicines and supplements. Examples that are commonly relevant:

• Herbal products and “natural” supplements
• Pain medicines (including high-dose or frequent use)
• Stomach remedies
• Antiemetics (anti-nausea medicines)

If you are unsure whether a product might interact with melphalan, ask your pharmacist.

Indications and When Alkacel May Be Considered

Melphalan is indicated for selected patients and clinical settings. Indications may include:

• Multiple myeloma and related plasma cell disorders
• Some malignancies where melphalan is part of an established regimen
• Conditioning regimens in certain specialist protocols (for example, in stem cell transplant pathways where used by specialists)

Your team may use melphalan alone or combined with other medicines depending on the goal of therapy (for example, disease control, remission induction, or preparation for additional treatment).

Dosing (How Dose Decisions Are Made)

Dosing of melphalan is individualised. It is based on factors such as:

• Your diagnosis and treatment intent
• Body size (often weight and/or body surface area)
• Kidney function (kidney health may affect safe dosing)
• Blood counts and history of prior chemotherapy tolerance
• Whether it is used as monotherapy or in combination

Important: Always follow the exact instructions on your medication label and the schedule your oncology team provides. Do not adjust your dose or dosing frequency without medical advice.

If you experience severe side effects (especially low blood counts, infections, or uncontrolled vomiting/diarrhoea), your oncology team may delay the next dose or reduce it.

Safety Profile: What to Expect

Like all cytotoxic chemotherapy, Alkacel can cause side effects. Not everyone will experience them, and many side effects can be managed effectively. The most important risks relate to bone marrow suppression and infection risk.

Common or clinically important side effects

• Low blood counts (myelosuppression): increased risk of infections, anaemia, or bleeding/bruising
• Nausea and vomiting
• Diarrhoea or constipation
• Fatigue
• Hair loss (may occur depending on regimen)
• Mouth sores or mouth inflammation
• Reduced appetite

Serious side effects—seek urgent help

Contact your oncology team promptly or seek urgent medical assistance if you develop any of the following:

• Fever (for example, a temperature that your team has instructed you to treat as an emergency)
• Signs of infection such as chills, sore throat, burning with urination, or worsening cough
• Severe diarrhoea, persistent vomiting, or signs of dehydration
• Unusual bleeding (for example, nosebleeds that won’t stop, blood in urine/stool, extensive bruising)
• Breathing difficulties or chest pain
• Severe allergic-type reactions (swelling, rash with breathing trouble)

Your oncology team may provide a specific “fever plan” and emergency contact details—keep these accessible.

Fertility and pregnancy considerations

• Pregnancy: Chemotherapy can harm an unborn baby. Use effective contraception during treatment and for an appropriate period after, as advised by your doctor.
• Breastfeeding: Breastfeeding is generally not recommended during chemotherapy.
• Fertility: Melphalan may affect fertility. Discuss fertility preservation options early if relevant to you.

These issues should be discussed before starting therapy, if possible.

Practical Use Tips (How to Take Alkacel Safely)

The most effective way to stay safe is to combine the right dosing schedule with proactive side-effect management and monitoring. Consider the tips below:

• Use the exact schedule on your instructions: Chemotherapy dosing relies on timing for both effectiveness and safety.
• Check the label every time: Confirm medicine name, dose, and instructions before each administration.
• Store safely: Store at the temperature indicated on the product label and keep out of reach of children.
• Handling and spill precautions: Cytotoxic medicines require careful handling. Follow pharmacy instructions for safe handling and disposal.
• Hydration: Maintain fluid intake as recommended by your oncology team to reduce dehydration risk.
• Manage nausea proactively: Use anti-nausea medicines exactly as prescribed, even before symptoms become severe (if your plan advises).
• Oral care: Brush gently, use recommended mouth rinses, and report mouth sores early.
• Infection prevention: Practice good hand hygiene and avoid contact with people who are unwell.

If you have difficulties swallowing tablets or experience significant nausea, speak with your pharmacist or oncology nurse—alternatives or supportive measures may be available.

Monitoring: Blood Tests and Follow-Up

During treatment, clinicians typically monitor:

• Full blood count (FBC): neutrophils/white cells, haemoglobin/anaemia, and platelets
• Kidney function: to ensure safe elimination
• Electrolytes and fluid status if you have vomiting or diarrhoea
• Liver function tests where relevant to your overall treatment plan

If blood counts are too low, your team may delay a dose, adjust the regimen, or provide supportive treatments.

Alternative Options (Discuss With Your Oncologist)

The “best” alternative depends on your cancer type, stage, prior treatments, and transplant plans. Alternatives to melphalan may include:

• Other chemotherapy agents used in combination regimens for your specific diagnosis
• Targeted therapies or immunotherapies where appropriate
• Supportive care approaches to reduce symptoms and complications (such as infection prevention strategies)
• Different conditioning or transplant-related protocols in specialist settings

Ask your oncologist about the rationale for choosing melphalan and what alternatives may exist if side effects occur or if your goals change.
