Melphalan (Alkeran) is an anticancer medication used to improve the quality of life (palliative care) for people with multiple myeloma or ovarian cancer. It’s a convenient pill that’s taken by mouth. This medication can also be given as an infusion into the vein (IV) for people with multiple myeloma. Melphalan (Alkeran) can raise your risk for serious infections and bleeding, so your provider will check your blood work closely.
Multiple myeloma - tablet and IV form
Ovarian cancer - tablet form only
Melphalan (Alkeran) is a type of anticancer medication called an alkylating agent. It works by damaging the cancer cells’ genetic material, leading to cell death.

Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report to your care team if they continue or are bothersome):
Available as a pill that you take by mouth
Can be given IV for people with multiple myeloma who have trouble swallowing tablets

Follow your provider’s instructions on which days to take melphalan (Alkeran) during each treatment cycle. It’s important to take this medication exactly as directed to make sure it’s as safe for you as possible.
You’ll need to get blood work done regularly during melphalan (Alkeran) treatment. Follow the lab schedule your provider gives you. This is so your provider can keep track of your blood cell counts. Melphalan (Alkeran) can lower your blood cell counts and put you at risk for bleeding or developing infections. Tell your care team if you develop a fever.
Keep the melphalan (Alkeran) tablets in the refrigerator at 36°F to 46°F (2°C to 8°C). Keep the tablets in the original bottle or amber bottle to protect them from light.
Before getting any vaccinations, let your healthcare provider or pharmacist know you’re taking melphalan (Alkeran). They can make sure it's safe for you to get the vaccine. Melphalan (Alkeran) can lower your immune system, which can affect how your body reacts to certain vaccines.
If you’re a woman who can have children, speak with your provider about ways to avoid becoming pregnant while taking melphalan (Alkeran). Let your provider know right away if you or your partner becomes pregnant during treatment. This medication can harm an unborn baby.
Ask your healthcare provider or pharmacist about the best way to handle and dispose of the melphalan (Alkeran) tablets. This medication can be hazardous to people who handle or come into contact with them.
Melphalan (Alkeran) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Melphalan (Alkeran) must be given by or under the supervision of a healthcare provider who's trained in caring for people taking chemotherapy medications. You must receive treatment at a clinic, hospital, or care facility that’s able to closely check for side effects and give you proper medical care, if needed.
Risk factors: Already having low blood cell counts from previous radiation or chemotherapy
Melphalan (Alkeran) can cause your red blood cell, white blood cell, and platelet counts to drop. When the number of these cells are lower than normal, you’re at risk of developing anemia, infections, and bleeding or bruising. In some cases, your blood cell counts might be low for a while. This is because your chemotherapy medications can weaken your bone marrow and affect its ability to make new blood cells like normal.
Your provider will closely check your blood counts through routine lab work when you’re taking melphalan (Alkeran). Let your provider know as soon as possible if you experience extreme tiredness, rapid breathing, fevers, chills, or bleeding and bruising that doesn’t stop or go away.
Although rare, it’s possible that you can develop other types of cancers, such as blood cancers (e.g., leukemias), when you take melphalan (Alkeran). Talk to your provider if you’re concerned about your risk for other cancers.
While rare, melphalan (Alkeran) can cause allergic reactions, which can be serious. These reactions can happen after several courses of treatment or if you’ve had a reaction after receiving melphalan (Alkeran) infusion into your vein in the past. Contact your provider or get medical help right away if you experience any throat tightness, trouble breathing, hives or rashes, swelling of the arms or legs (edema), fast heartbeat, or dizziness.
Based on findings from animal studies, melphalan (Alkeran) can harm an unborn baby. If you’re a woman who can have children, you should avoid becoming pregnant while taking this medication. Let your provider know right away if you or your partner becomes pregnant during treatment.
Melphalan (Alkeran) might also affect your ability to have a baby. If you or your partner are thinking about having a child in the future, talk to your provider about your different options before starting melphalan (Alkeran), such as sperm banking or egg freezing.

Multiple myeloma
Tablets: The typical dose is 6 mg by mouth once a day for 2 to 3 weeks, followed by an off period for up to 4 weeks. You’ll need to get lab work done regularly during this time so your provider can check your blood cell counts. Once your blood cell counts are trending up, the recommended maintenance dose is 2 mg daily.
Intravenous (IV): Your provider will calculate your dose of melphalan (Alkeran) using your body surface area (BSA, in units of m2), which takes into account your body weight and height. The typical dose is 16 mg/m2 given as an infusion through the vein every 2 weeks for 4 doses, followed by an off period. Once your blood cell counts are trending up, you’ll receive melphalan (Alkeran) every 4 weeks.
Ovarian cancer
Tablets: The dose depends on your weight. One typical dosing regimen is 0.2 mg/kg by mouth once a day for 5 days per cycle. Each cycle is repeated every 4 to 5 weeks depending on your blood cell counts.
Your dose might differ if you have kidney problems.
