Alkacel (Melphalan) — Patient Information (Australia)

Alkacel contains melphalan, a chemotherapy medicine used in specific cancer conditions. This page explains what Alkacel is, how it works, how it is used, practical safety considerations, and what you can expect regarding timing, food, and interactions. It is written in a patient-friendly way for use by people in Australia.

Important: Always follow the treatment plan provided by your oncology team. Chemotherapy medicines can be unsafe if taken incorrectly.

Basic product information

• Medicine name: Alkacel
• Active ingredient: Melphalan
• Medicine type: Anticancer (cytotoxic) chemotherapy
• Common formulations: Alkacel is supplied as melphalan for oral or specialist use depending on local supply and treatment protocols. Your product packaging and instructions will specify the exact form and strength.
• Therapy setting: Often used under oncology supervision for haematological cancers and certain solid tumour indications.

How it may be taken: In many settings, melphalan is taken by mouth, but some protocols may also involve administration routes or regimens used in hospitals. Your medication label will provide details.

How Alkacel works (mechanism of action)

Melphalan is an alkylating agent. It works by damaging cancer cell DNA so that cancer cells cannot divide and grow.

• After entering the body, melphalan is converted into reactive compounds.
• These reactive compounds attach to DNA strands.
• This causes cross-linking of DNA and other DNA damage.
• As a result, cancer cells undergo cell death, especially rapidly dividing cells.

Because melphalan affects both cancer cells and some healthy rapidly dividing cells (such as bone marrow cells, hair follicles, and the lining of the gut), side effects commonly relate to those tissues.

Pharmacokinetics (how the body handles melphalan)

Pharmacokinetics describes absorption, distribution, metabolism, and elimination.

• Absorption: Oral absorption can vary between individuals. Gastrointestinal effects (such as nausea and vomiting) may affect how much medicine is absorbed.
• Distribution: Melphalan distributes throughout the body; it reaches tissues where cancer may be present.
• Metabolism: It is broken down to less active metabolites primarily by chemical and enzymatic processes in the body.
• Excretion: Metabolites are eliminated mainly via the kidneys and partly through other pathways.
• Timing-related factors: Blood counts (especially neutrophils and platelets) may drop after treatment; the degree and timing can help guide future doses.

Clinicians monitor blood counts and adjust therapy based on response and tolerability.

Typical use and indications

Melphalan is used for selected cancers. The exact indication depends on your diagnosis, prior treatment, overall health, and treatment plan.

Common indications

• Multiple myeloma: A blood cancer of plasma cells. Melphalan is commonly used in combination regimens and may be used around the time of treatment strategies such as stem cell transplantation protocols (where applicable).
• Ovarian cancer and other gynaecologic malignancies: In certain cases, melphalan may be used as part of a chemotherapy regimen.
• Some solid tumours (selected settings): Depending on local practice, guidelines, and availability.
• Specialist protocols: Melphalan may be used in certain conditioning regimens for transplantation or other high-specialty protocols.

Note: Indications and dosing may differ depending on whether melphalan is being used as part of a combination regimen, as part of a high-dose strategy, or in other specialist contexts.

Dosing overview (how Alkacel dosing is determined)

Dose and schedule must be individualised. Alkacel dosing varies by cancer type, treatment goal (for example, induction, consolidation), combination regimen, kidney function, blood counts, and tolerability.

Key points about dosing

• Body surface area or weight-based dosing: Many chemotherapy protocols use a calculation based on height and weight (body surface area) to determine dose.
• Blood count recovery: Doses may be delayed or reduced based on neutrophil and platelet counts.
• Kidney function: Reduced kidney function may increase exposure. Your clinician may adjust dosing and monitor more closely.
• Combination with other medicines: When used with other chemotherapy drugs, the timing and dose may differ from melphalan used alone.

Do not self-adjust

Do not change the dose, frequency, or schedule without your oncology team. Stopping or altering chemotherapy can affect effectiveness and may increase risk if timing is changed incorrectly.

Timing: when and how to take Alkacel

Your treatment schedule will be written on your prescription label and treatment plan. In general:

• Follow your cycle schedule exactly: Chemotherapy is often given in cycles with rest periods to allow normal cells to recover.
• Consistency matters: Take doses at the same times on each day your plan specifies.
• Missed dose: If you miss a dose, contact your oncology team or pharmacist for instructions. Do not “double up” unless specifically told to do so.

Practical timing tip: Many people find it easier to plan the day around possible nausea, fatigue, and hydration needs.

Food interactions (what to eat and when)

Food can affect chemotherapy medicines differently depending on formulation and absorption characteristics. For melphalan, food interactions are clinically relevant.

General guidance

• Follow your medicine label instructions: Some melphalan regimens specify taking doses either on an empty stomach or with a certain timing relative to food.
• If you are unsure: Ask your pharmacist to confirm the recommended timing for your specific product.
• Manage nausea: If nausea occurs, ask about anti-nausea medicines. Maintaining hydration is important.

Food safety during chemotherapy: Consider avoiding undercooked foods, and follow any “neutropenic diet” advice provided by your oncology team, especially when blood counts are low.

Alcohol interactions

Alcohol may worsen side effects such as:

• Nausea and vomiting
• Fatigue
• Dehydration
• Reduced appetite

Alcohol may also increase strain on the body during cancer treatment. Your oncology team may advise limiting or avoiding alcohol while on melphalan, particularly if liver function is affected or if you experience significant gastrointestinal side effects.

Practical advice: If you choose to drink, keep alcohol minimal and discuss it with your doctor or pharmacist so it can be considered within your overall treatment safety plan.

Medicine interactions (including over-the-counter and herbal products)

Melphalan can interact with other medicines. These interactions may affect melphalan exposure or increase side effects such as bone marrow suppression and infection risk.

Common interaction considerations

• Other chemotherapy or radiation: May increase risks of low blood counts and side effects.
• Medicines that affect bone marrow: Other treatments that suppress blood production can increase risk of infections, anaemia, and bleeding.
• Vaccines: Live vaccines may be inappropriate during chemotherapy. Inactivated vaccines may also require timing considerations; confirm with your doctor.
• Immunosuppressive medicines: Can increase infection risk.
• Herbal and complementary products: Some may affect metabolism, bleeding risk, or immune function. Always disclose them.
• Anti-nausea medicines and supportive care: Often used and generally compatible, but individual combinations should be checked.

Tell your pharmacist about:

• All prescription medicines
• Over-the-counter medicines (including pain relief and cold/flu products)
• Herbal products, vitamins, and supplements
• Any recent or upcoming procedures

If you are ever uncertain, ask before starting a new product.

Safety profile: common and serious side effects

Melphalan can affect fast-growing cells in the body. Not everyone experiences all side effects, but it is important to know what may happen and when to seek urgent help.

Common side effects

• Low blood counts (myelosuppression): increases risk of infections, tiredness, and bruising/bleeding
• Nausea and vomiting
• Diarrhoea or constipation
• Loss of appetite
• Fatigue
• Hair thinning (may occur with certain regimens)
• Mouth sores (mucositis)
• Skin rash or irritation (less common)

Serious risks (contact your clinician urgently)
