Alkacel (Melphalan) — Patient Information Guide (Australia)

Alkacel contains melphalan, a chemotherapy medicine used to treat certain cancers. This page explains what Alkacel is, how it works, how it’s used, important safety considerations, and practical tips to help you prepare for treatment. It is written for people seeking clear, patient-friendly information for use in Australia.

1) Basic product information

• Brand name: Alkacel
• Active ingredient: Melphalan
• Medicine type: Antineoplastic (chemotherapy) agent
• Common dosage forms: Usually supplied as capsules or as a formulation used for specific treatment protocols (your pharmacy and oncology team will confirm the exact form and strength you have).
• Who supplies it in Australia: Available through authorised channels via prescription workflows and specialty oncology services.

Cancer treatments are personalised. Your doctor will decide the dose, schedule, and treatment plan based on your diagnosis, blood counts, kidney function, other medicines, and whether treatment is part of a transplant or non-transplant regimen.

2) What melphalan does (mechanism of action)

Melphalan is an alkylating agent. It damages the DNA inside rapidly dividing cancer cells, preventing them from growing and multiplying. It does this by attaching reactive chemical groups to DNA, which leads to DNA strand cross-linking and ultimately cell death.

Because melphalan affects cells that divide quickly, it can also affect healthy bone marrow cells and the lining of the gastrointestinal tract. This is why blood count decreases and nausea/mouth or bowel effects are common risks.

3) Pharmacokinetics (how the body processes Alkacel)

Pharmacokinetics describes absorption, distribution, metabolism, and elimination. Exact details can vary with dosage form and individual factors.

Absorption and distribution

• Absorption: When taken by mouth, melphalan is absorbed from the gastrointestinal tract, but absorption can be affected by food.
• Distribution: After absorption, melphalan distributes into tissues; cancer treatment effectiveness depends on achieving appropriate exposure.

Metabolism and elimination

• Metabolism: Melphalan is partly metabolised in the body.
• Elimination: It is cleared through metabolism and excretion pathways, with kidney function influencing how long drug exposure may last.

Your clinician may monitor kidney function and blood counts during treatment, adjusting dosing if needed.

4) Typical uses (indications)

Alkacel (melphalan) is used to treat several cancers, depending on the regimen used.

Common indications

• Multiple myeloma: Often used in induction/conditioning approaches and in combination regimens. Melphalan is widely used as part of conditioning therapy before certain stem cell transplant procedures.
• Ovarian cancer: In selected settings, often in combination with other agents.
• Other malignancies: It may be used for specific cancers where melphalan is an appropriate choice, depending on national treatment guidelines and clinician judgement.

The exact “why” for your use (for example, before a transplant versus as part of a multi-drug regimen) will determine timing, monitoring, and supportive care.

5) How and when Alkacel is taken (timing and schedule)

Timing depends on the protocol. Some regimens use fixed daily doses over a short period; others use dosing on one or more days within a cycle. Always follow your treatment plan exactly as provided by your oncology team.

Key timing points

• Attend scheduled appointments: Blood tests are commonly timed to before each treatment cycle and at intervals to monitor recovery.
• Consistency matters: If your protocol requires daily dosing, take each dose at the times instructed.
• Supportive medicines: Anti-nausea medicines and other supportive care may be scheduled before melphalan to reduce side effects.

If you miss a dose, do not double. Contact your treating team or pharmacist promptly for guidance.

6) Food interactions (what to know before taking)

Food can affect melphalan absorption. This means what you eat around the time you take a dose may change how much medicine reaches your bloodstream.

Practical advice

• Follow your instructions exactly regarding taking with food or on an empty stomach (your regimen may specify one approach).
• If you are told to take it without food:
  • Take the dose as directed, allowing the required time before or after meals.
• If your instructions allow taking with food:
  • Try to keep meals consistent from day to day.

Because melphalan exposure may change with food, consistent timing and meal patterns help maintain predictable treatment delivery.

7) Alcohol interactions

There is no single universal “safe amount” of alcohol for all people taking chemotherapy. Alcohol can worsen side effects and affect hydration, liver function, and sleep—factors that can already be strained during cancer treatment.

• Recommendation: Discuss alcohol with your oncology team.
• Extra caution: Avoid alcohol if you experience significant nausea, vomiting, mouth sores, severe fatigue, or low blood counts.
• Do not use alcohol-containing elixirs or mixtures unless your pharmacist confirms they are appropriate for your situation.

8) Medicine interactions (common and important interactions)

Alkacel can interact with other medicines through effects on blood counts, kidney function, infection risk, or absorption. Always review your full medicine list (including over-the-counter products, vitamins, herbal supplements, and “as needed” medicines) with your pharmacist.

Medicines that may require extra review

• Other chemotherapy or medicines that affect bone marrow: May increase risk of low blood counts.
• Medicines that suppress the immune system: May increase infection risk.
• Antibiotics or antiviral medicines: Some may have supportive roles; others may alter risk depending on kidney function.
• Medicines affecting kidney function: If kidney function changes, melphalan clearance may change.
• Vaccines: Live vaccines may be unsafe during certain phases of chemotherapy; check before immunisations.
• Herbal products and supplements: Some can affect blood counts or liver/kidney pathways. Avoid starting new supplements without advice.

Over-the-counter cautions

• Pain relief: Use only what your clinician recommends. In people with low platelets, some pain medicines (for example, those that increase bleeding risk) may not be suitable.
• Cold/flu products: Many contain multiple ingredients. Check labels and ask your pharmacist.

Keep an updated list of all medicines and bring it to appointments.

9) Dosing: what people commonly ask

Dosing of melphalan is highly individual. It is based on:

• Your diagnosis and treatment regimen
• Your body size (commonly body surface area)
• Blood counts and recovery patterns
• Kidney function
• Whether this is used alone, in combination, or as conditioning therapy

Doses may be given over multiple days or as a single day within a cycle, depending on the protocol. Your oncology team will also schedule lab tests to ensure you are safe to continue and to help adjust dosing if you experience side effects.

How dosing is commonly managed

• Before each cycle: Blood tests check whether your bone marrow is strong enough.
• During treatment: Your team may adjust the next dose if counts are low or if side effects occur.
• After treatment: Recovery of white blood cells, haemoglobin, and platelets is monitored.

Important: Do not change dose or schedule yourself. Chemotherapy dosing affects safety and effectiveness.

10) Safety profile and side effects

Like all chemotherapy, Alkacel can cause side effects. Some are expected and manageable with supportive care. Others require urgent medical attention. Your oncology team will discuss likely risks for your specific regimen.

Common side effects

• Low blood counts (myelosuppression): increases risk of infection, anaemia-related tiredness, and bruising/bleeding from low platelets.
• Nausea and vomiting
• Diarrhoea or constipation
• Mouth sores (mucositis)
• Loss of appetite
• Fatigue
• Hair loss can occur with some chemotherapy regimens (not always universal).

Serious risks—when to seek help urgently

Seek urgent medical advice or emergency care if you experience:

• Fever: especially if you are receiving chemotherapy and your white cell count may be low.
• Signs of infection: chills, feeling very unwell, worsening cough, burning when urinating.
• Unusual bleeding or bruising: nosebleeds that won’t stop, blood in urine/stool, black/tarry stools, or severe gum bleeding.
• Severe mouth sores preventing drinking or eating.
• Severe diarrhoea or vomiting that prevents hydration.
• Severe allergic reaction: swelling of face/lips, wheezing, or rash with breathing difficulty.

Long-term considerations

Certain chemotherapy medicines can be associated with longer-term effects. Your oncology team can explain what’s relevant for your planned regimen, including:

• Potential impacts on fertility
• Risk of secondary malignancies (rare, but discussed as part of informed consent)
• Cardiovascular or other organ considerations depending on your overall treatment history

11) Practical use tips (daily-life guidance)

Small habits can make treatment safer and more tolerable. Always follow your clinician’s specific instructions.

Infection prevention

• Ask if you should avoid crowds or close contact with people who are sick.
• Practice good hand hygiene.
• Keep your mouth and skin clean and report mouth sores early.
• Use a thermometer if your team recommends it, and know your fever action plan.

Managing nausea and appetite changes

• Take anti-nausea medicines exactly as prescribed, even if you feel okay.
• Choose small, frequent meals and sip fluids throughout the day.
• If certain foods worsen nausea, avoid them and ask your team about dietary support.

Hydration and bowel care

• Maintain hydration unless you’ve been told to restrict fluids.
• Report persistent diarrhoea early; it may need prompt treatment.
• Avoid starting new laxatives or anti-diarrhoeal medicines without checking first.

Handling and storage precautions

• Store your medicine as directed on the label (temperature and light protection if specified).
• Keep out of reach of children.
• Do not break, crush, or open capsules unless your pharmacist confirms it is appropriate.

If your Alkacel is in capsule form, follow your pharmacy’s instructions precisely. Chemotherapy medicines require careful handling to protect you and others around you.

12) Alternative options (discuss with your oncology team)

“Alternative” can mean different chemotherapy agents, different combinations, or different schedules. The most suitable alternative depends on your cancer type, stage, prior treatments, and overall health.

Possible alternatives to discuss

• Other chemotherapy regimens used for multiple myeloma or ovarian cancer (for example, combinations that may include different cytotoxic agents and steroids).
• Targeted therapies (in selected patients and disease subtypes).
• Immunotherapy approaches depending on diagnosis and eligibility.
• Supportive care improvements that reduce side effects (anti-nausea protocols, growth factor support, infection prevention strategies) which may accompany melphalan use.

Your treating team can explain why Alkacel is chosen for your case, and what options could be considered if adjustments are needed.

13) Market and legal context for Australia (what this means for access)
