⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾
Melphalan carries serious black-box warnings that every patient should know about.
Severe bone marrow suppression: Melphalan can dramatically reduce your body's ability to make blood cells, leading to life-threatening infections or bleeding. IV melphalan causes more of this effect than oral melphalan. Your blood counts will be monitored closely throughout treatment.
Severe allergic reactions: About 2% of patients receiving IV melphalan have experienced serious hypersensitivity reactions — including anaphylaxis (a sudden, life-threatening allergic response). Signs include hives, swelling, trouble breathing, rapid heartbeat, and low blood pressure. If a serious reaction occurs, Ivra must be stopped immediately and should not be restarted.
Risk of causing a new cancer (leukemogenicity): Melphalan can damage chromosomes and has been linked to the development of secondary cancers, including certain leukemias. Ivra in particular should be considered potentially capable of causing leukemia in humans.

🎯What it's used for▾
Melphalan is a chemotherapy drug approved for use in multiple myeloma. Different products are approved for different roles:
- Evomela (intravenous injection) is indicated as a high-dose conditioning regimen prior to autologous hematopoietic progenitor (stem) cell transplantation in patients with multiple myeloma.
- Ivra (intravenous injection) is indicated for the palliative treatment of multiple myeloma in patients for whom oral therapy is not appropriate.
- Alkeran (oral tablet) is used for the palliative treatment of multiple myeloma.
⚙️How it works▾
Melphalan belongs to a class of chemotherapy drugs called alkylating agents. It works by chemically bonding to DNA inside cancer cells — specifically cross-linking the two strands of the DNA double helix together at a site called the N7 position of guanine. This damage prevents the cell from reading or copying its DNA, which stops it from dividing and ultimately causes the cancer cell to die. Unlike some chemotherapy drugs that only target rapidly dividing cells, melphalan is also active against cancer cells that are in a resting state.
💊How it's taken▾
Melphalan is available as an intravenous (IV) injection and as an oral tablet, and dosing depends entirely on which product and indication applies to you — always follow your prescriber's exact plan.
- Evomela (IV) is given as a daily infusion over about 30 minutes for two consecutive days prior to a stem cell transplant.
- Ivra (IV) is infused over 15 to 20 minutes — typically every two weeks for the first four doses, then every four weeks based on how your blood counts recover.
- Alkeran (oral tablet) is taken by mouth on a schedule determined by your prescriber; repeated treatment courses are often needed since improvement can be gradual over many months.
Your blood counts will guide dose adjustments throughout treatment. Never stop or change your dose without talking to your care team first.
🤒Side effects — in detail▾
Melphalan affects blood cell production in nearly all patients, and many other side effects are possible depending on the dose and formulation used.
- Decreased neutrophils, white blood cells, lymphocytes, and platelets (expected in almost all patients)
- Anemia (low red blood cells)
- Nausea and vomiting
- Diarrhea
- Fatigue
- Mouth sores (stomatitis, mucosal inflammation)
- Low potassium (hypokalemia) and low phosphate (hypophosphatemia)
- Fever, including febrile neutropenia (fever with dangerously low white blood cell counts)
- Decreased appetite, dizziness, constipation, abdominal pain
Seek immediate medical attention for signs of serious infection (fever, chills), unusual bleeding or bruising, symptoms of a severe allergic reaction (difficulty breathing, swelling, rapid heartbeat), or yellowing of the skin or eyes.
⚠️Warnings & precautions▾
- Severe bone marrow suppression: Melphalan suppresses bone marrow function in most patients, reducing blood cells and increasing the risk of serious infection and bleeding. Blood counts must be monitored before every dose. IV melphalan causes more suppression than oral melphalan.
- Serious allergic reactions (hypersensitivity/anaphylaxis): About 2% of patients receiving IV melphalan have had severe reactions, including life-threatening anaphylaxis. If this occurs, IV melphalan must be stopped and should not be restarted — oral melphalan has also caused reactions.
- Secondary cancers: Melphalan can damage chromosomes and has been associated with the development of secondary leukemias and other cancers. This long-term risk must be weighed against the benefit of treating multiple myeloma.
- Liver toxicity (hepatotoxicity): Liver problems ranging from abnormal lab values to hepatitis, jaundice, and veno-occlusive disease (blockage of blood vessels in the liver) have been reported. Liver enzymes should be monitored.
- Fetal harm: Melphalan can cause serious birth defects or pregnancy loss. Effective contraception is required during and after treatment.
- Fertility effects: Melphalan can suppress ovarian function in women and testicular function in men — these effects may or may not be reversible.
- Gastrointestinal toxicity: Nausea, vomiting, diarrhea, and mouth sores are common; at high doses, severe colitis and gastrointestinal bleeding can occur.
🔀What it interacts with▾
Melphalan can interact with several other medications in ways that increase the risk of serious harm. Tell your care team about everything you take.
- Cyclosporine: A single IV dose of melphalan followed by standard oral cyclosporine doses has caused severe kidney failure.
- Cisplatin: This chemotherapy drug can reduce kidney function, which in turn affects how the body clears melphalan — potentially increasing melphalan's effects and toxicity.
- BCNU (carmustine): IV melphalan may lower the dose of BCNU needed to cause lung toxicity, increasing that risk.
- Nalidixic acid: When given at the same time as IV melphalan, this antibiotic has been linked to a higher rate of severe, hemorrhagic (bleeding) bowel inflammation, particularly in children.
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Severe prior allergic reaction to melphalan: Ivra is contraindicated if you have had a serious hypersensitivity reaction to melphalan — tell your doctor before starting any melphalan product.
- Kidney problems: Impaired kidney function can affect how melphalan is cleared; a dose reduction may be needed, especially with IV formulations.
- Liver problems: Liver function should be monitored during treatment; hepatic disorders have been reported.
- Pregnancy: Melphalan can cause fetal harm or pregnancy loss. Females of reproductive potential should use effective contraception during treatment and for 6 months after the last dose of IV melphalan.
- Males with reproductive-age partners: Melphalan may damage sperm and cause genetic harm to a fetus; use effective contraception during treatment and for 3 months after the last dose of IV melphalan.
- Breastfeeding: Do not breastfeed during treatment or for at least one week after the last IV dose — melphalan's effects on a breastfed infant are unknown but potentially serious.
- Children: The safety and effectiveness of IV melphalan have not been established in pediatric patients.
- Older adults: Elderly patients should be started at lower doses with caution, as age-related declines in kidney, liver, and heart function can increase the risk of side effects.
🚑If you take too much▾
Overdose with melphalan is very serious and has caused death. Too much can produce severe nausea and vomiting, decreased consciousness, seizures (convulsions), muscle paralysis, and severe damage to the mouth, bowels, and gastrointestinal tract. The most dangerous effect is profound bone marrow suppression, which requires close monitoring of blood counts for three to six weeks after an overdose. There is no specific antidote; treatment is supportive care, and melphalan is not effectively removed by dialysis.
📡Pharmacodynamics — effects in the body▾
Melphalan exerts its anti-cancer effects by cross-linking the two strands of DNA inside tumor cells, which prevents those cells from replicating. It is active against both resting and rapidly dividing cancer cells. The main measurable effect in patients is bone marrow suppression — nearly all patients experience significant decreases in white blood cells, neutrophils, lymphocytes, and platelets during treatment, which is monitored closely to guide dosing.
🔬Pharmacokinetics — how your body processes it▾
After IV injection, melphalan levels in the blood drop rapidly in two phases: an initial distribution phase with a half-life of about 10 minutes, followed by a longer elimination phase with a half-life of about 75 minutes. The drug binds extensively to plasma proteins (53–92%), primarily albumin. Melphalan does not significantly penetrate the fluid around the brain and spinal cord. It is broken down mainly by a natural chemical process (hydrolysis) in the blood rather than by the liver, producing two inactive breakdown products. Very little is removed by the kidneys directly, but reduced kidney function can affect overall clearance and increase the risk of toxicity, so dose reductions are considered in patients with kidney impairment.
📦How to store it▾
Store at 20° to 25°C (68° to 77°F). Protect from light.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Melphalan — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Melphalan in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 9 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Acrotech Biopharma Inc is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
