Alkacel (Melphalan) – Patient Information (UK)

Alkacel is a medicine containing melphalan. It is used to treat certain cancers by interfering with the growth and division of cancer cells. This page explains what Alkacel is, how it works, how it is used, important safety information, and practical guidance for people in the United Kingdom.

Important: Cancer treatments are personalised. Always follow the instructions you are given by your treating healthcare team. If you have questions about your regimen, contact your clinic or pharmacist.

Basic product information

What is melphalan?

Melphalan is a chemotherapy medicine classified as an alkylating agent. Alkylating agents damage the DNA in rapidly dividing cells, leading to cell death. Cancer cells are often more sensitive than normal cells, but side effects can still occur because healthy tissues also divide (for example, bone marrow and cells lining the gut).

How Alkacel works (mechanism of action)

Melphalan works by adding alkyl groups to DNA. This interferes with DNA replication and transcription. When DNA cannot be properly copied or repaired, cancer cells stop dividing and may die.

Because the effect depends on the ability of cancer cells to replicate, the medicine is typically used in structured treatment cycles (course length and breaks vary by indication and regimen).

Pharmacokinetics (how the body handles melphalan)

Pharmacokinetics (PK) describes what happens after the medicine enters the body, including absorption, distribution, metabolism, and excretion.

• Absorption: For oral formulations, absorption occurs through the gastrointestinal tract. Food can influence how much melphalan reaches the bloodstream (see “Food interactions” below).
• Distribution: Melphalan circulates and can reach tissues involved in cancer, including bone marrow. Distribution can be influenced by disease state and general health.
• Metabolism: Melphalan is processed in the body through chemical transformation pathways.
• Elimination: The medicine and its metabolites are eliminated primarily by the kidneys and/or through metabolism and subsequent clearance routes. Kidney function can therefore be relevant to tolerability.
• Bone marrow effects: Even if blood levels change over time, the key safety concern—bone marrow suppression—reflects the downstream effect on rapidly dividing blood-forming cells.

Your prescriber may monitor blood counts closely and adjust doses according to your blood results and side effects.

What is Alkacel used for? (typical indications)

Melphalan is used in certain cancers, most notably:

• Multiple myeloma (a cancer of plasma cells), often in combination regimens.
• Some protocols may also use melphalan as part of conditioning treatment prior to stem cell procedures in selected patients (the exact plan depends on the specialist centre’s protocol).

Note: Which regimen you receive—dose, schedule, and combination medicines—depends on the specific diagnosis, stage, prior treatments, age, performance status, kidney/liver function, and overall risk profile.

Dosing and timing

Dosing must be individualised. The information below is general and may not match your personal plan.

How dosing is usually determined

• Indication and regimen type (single-agent versus combination therapy; continuous versus cycle-based dosing)
• Body size (some regimens use body surface area)
• Blood test results (especially neutrophils, platelets, and haemoglobin)
• Organ function (particularly kidney function)
• Previous chemotherapy and recovery from earlier cycles

Typical timing considerations

• Take at the same times each day when you are prescribed daily dosing schedules.
• Cycle structure: Many chemotherapy regimens use a pattern of treatment days followed by rest days to allow blood counts to recover.
• Concomitant medicines: Some people take anti-sickness medicines and other supportive therapies at set times around the Alkacel dose.

What to do if you miss a dose: Do not take extra doses without advice. Contact your chemotherapy team or pharmacist for guidance based on your cycle schedule and how late you are.

Food interactions

Food can affect the absorption of some oral chemotherapy medicines. For melphalan, food may reduce absorption and can therefore impact how well the medicine works.

• Follow your prescribed instructions regarding whether Alkacel should be taken on an empty stomach or with a specific relationship to meals.
• If you are told to take it between meals, aim to follow that schedule consistently.
• If you have vomiting, diarrhoea, or appetite changes, talk to your team—these can affect nutrition and may also affect how well oral medicines are absorbed.

Practical tip: Keep a simple routine (for example, taking it at the same times of day) and mark your dosing schedule on a calendar. If nausea affects your ability to eat or drink, anti-sickness medicines may help.

Alcohol interactions

Alcohol is not usually a “direct” interaction with melphalan in the way some medicines are, but it can increase risks during chemotherapy by worsening side effects such as:

• Nausea and vomiting
• Diarrhoea or stomach irritation
• Drowsiness when combined with anti-sickness medicines that may affect alertness
• Dehydration (which can affect kidney function)
• Reduced nutrition and overall recovery

Advice: It’s generally best to limit or avoid alcohol during treatment unless your clinician has confirmed it is acceptable for you.

Interactions with other medicines

Melphalan can interact with other medicines mainly through effects on the bone marrow, immunity, or the liver/kidneys (depending on what else you take). Always tell your healthcare team about everything you use, including over-the-counter products and herbal remedies.

Medicines that may need extra care

• Other chemotherapy or bone-marrow suppressing medicines (can increase risk of low blood counts)
• Live vaccines (typically avoided during chemotherapy because immunity may be reduced)
• Medicines that can affect kidney function (your team may monitor more closely)
• Medicines for nausea, sleep, or anxiety (they may add to fatigue or dizziness)
• Antibiotics or antifungals (may be used during low white blood cell periods; your team will select options appropriately)

If you are unsure whether a specific medicine is safe alongside Alkacel, ask your pharmacist. Do not start or stop medicines without advice.

Safety profile and important risks

Like other chemotherapy medicines, Alkacel can cause side effects. Some are predictable and manageable, while others require urgent assessment.

Common or expected side effects

• Low blood counts (bone marrow suppression), including:
  • Neutropenia (low neutrophils → higher infection risk)
  • Anaemia (low red blood cells → tiredness, breathlessness)
  • Thrombocytopenia (low platelets → bruising or bleeding risk)
• Nausea and sometimes vomiting
• Diarrhoea or constipation
• Loss of appetite
• Fatigue or weakness
• Hair thinning in some people (may be less common than with some other chemotherapy agents)
• Mouth ulcers or mouth soreness
• Skin changes such as rash or irritation

Serious risks—when to seek urgent help

Contact your cancer team urgently or seek emergency medical care if you develop:

• Signs of infection, such as:
  • Fever (often defined as a temperature of ≥ 38°C)
  • Chills, rigors, severe sore throat, or feeling very unwell
• Uncontrolled bleeding (for example, repeated nosebleeds, blood in urine or stool, unusual bruising)
• Severe breathlessness, chest pain, or fainting
• Persistent vomiting or unable to keep fluids down
• Severe diarrhoea or signs of dehydration

Why this matters: Low white blood cell counts can cause infections to become serious quickly during chemotherapy.

Pregnancy, fertility, and contraception

• Melphalan can harm an unborn baby.
• Both women and men should discuss fertility and contraception with their specialist before starting treatment.
• Contraception is usually recommended during chemotherapy and for a period afterwards. Your team will advise the exact duration.

Allergy and hypersensitivity

Seek medical advice if you develop signs of allergy such as swelling of the face/lips, widespread rash, or difficulty breathing.

Practical use tips for everyday life

Before you start

• Make sure you understand your dose, schedule, and the relationship with meals.
• Plan for regular blood tests as advised—this is key to safe dosing.
• Ask about supportive medicines (anti-sickness tablets, mouth care, gut protection, infection prevention if appropriate).

During treatment

• Infection prevention: Practise good hand hygiene and avoid close contact with people who have contagious illnesses.
• Hydration: Aim for regular fluid intake unless you have fluid restrictions from your clinician.
• Oral care: Keep your mouth clean; use gentle brushing and avoid alcohol-based mouthwashes if advised.
• Nutrition: If appetite is low, smaller meals and calorie-dense snacks may help. A dietitian can support you.
• Track symptoms: Keep a simple diary of side effects (nausea, bowel changes, fever, bruising, pain) and bring it to appointments.

Handling and storage

• Keep the medicine out of the sight and reach of children.
• Store it as directed on the packaging (temperature and light protection requirements vary by product presentation).
• If a capsule/tablet form is prescribed, follow your pharmacy’s handling instructions.

Alternative options

Cancer treatment depends on the type and stage of disease, your overall health, and prior therapy. Alternatives to Alkacel (melphalan) may include:

• Other chemotherapy agents used in multiple myeloma and related conditions (for example, different alkylating agents or combination chemotherapy regimens).
• Targeted therapies and immunotherapies that may be used in some myeloma treatment pathways.
• Stem cell transplant conditioning regimens where appropriate (the conditioning may use melphalan or a different agent depending on protocol).

Your haematology/oncology team can explain why melphalan is recommended in your case and what other options exist.
