Generic Name: melphalan (MEL fa lan)Brand Names: Alkeran, Alkeran I.V.

What is melphalan?

Melphalan is a cancer medication. Melphalan interferes with the growth of cancer cells and slows their growth and spread in the body.

Melphalan is used to treat multiple myeloma (a type of blood cancer), cancer of the ovary, and breast cancer.

Melphalan may also be used for other purposes not listed in this medication guide.

What is the most important information I should know about melphalan?

Do not use this medication if you are pregnant. It could cause harm to the unborn baby. Use an effective form of birth control, and tell your doctor if you become pregnant during treatment. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Melphalan can cause serious side effects, including: decreased bone marrow function and blood problems (easy bruising or bleeding, unusual weakness, fever, chills, body aches, flu symptoms, bloody or black stools, pale or yellowed skin, confusion or weakness); breathing problems; or liver damage (nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, jaundice [yellowing of the skin or eyes]). Call your doctor at once if you have any of these side effects.

In some cases, second cancers have been reported to occur during and after treatment with melphalan. Talk to your doctor about your individual risk and benefit of this medication.

What should I discuss with my healthcare provider before using melphalan?

Before using melphalan, tell your doctor if you have:

  • kidney disease; or
  • decreased bone marrow (from other diseases or medications).

If you have any of these conditions, you may not be able to use melphalan, or you may need a dosage adjustment or special tests during treatment.

FDA pregnancy category D. This medication can cause harm to an unborn baby. Do not use melphalan if you are pregnant. Tell your doctor if you become pregnant during treatment. Use an effective form of birth control while you are using this medication.

This medication can affect fertility (your ability to have children), whether you are a man or a woman.

It is not known whether melphalan passes into breast milk or if it could harm a nursing baby. Do not take melphalan without telling your doctor if you are breast feeding a baby.

How should I take melphalan?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger or smaller amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.

Your doctor may occasionally change your dose to make sure you get the best results from this medication.

Take the melphalan oral tablet with a large glass of water.

Melphalan injection is given through a needle placed into a vein. Your doctor, nurse, or other healthcare provider will give you this injection in a clinic or hospital setting.

Tell your doctor right away if any of the melphalan injection gets on your skin or if you feel pain, burning, or other skin irritation when the medicine is injected.

Melphalan is usually given for a few weeks at a time, followed by a 4-week period off the drug, during which your blood is tested to see how your body responded to the medication. Your doctor will determine how often you use melphalan and for how long. Follow your doctor's instructions carefully.

Melphalan can lower the blood cells that help your body fight infections. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. To be sure your blood cells do not get too low, your blood will need to be tested on a regular basis. It is important that you not miss any scheduled visits to your doctor.

Store melphalan tablets in the refrigerator and protect them from light. If you store melphalan injection at home, keep it at room temperature and protect it from heat, moisture, and light.

Melphalan Dosing Information

Usual Adult Dose for Multiple Myeloma:

Usual Intravenous Dose: 16 mg/m2 The drug is administered as a single infusion over 15 to 20 minutes. Melphalan is administered at two week intervals for four doses, then, after adequate recovery from toxicity, at four week intervals.Usual Oral Dose: 6 mg once a day. After 2 to 3 weeks of treatment, the drug should be discontinued for up to 4 weeks during which time the blood count should be followed carefully. When the white blood cell and platelet counts are rising, a maintenance dose of 2 mg daily may be instituted. Because of the patient to patient variation in melphalan plasma levels following oral administration of the drug, several investigators have recommended that the dosage of melphalan be cautiously escalated until some myelosuppression is observed in order to assure that potentially therapeutic levels of the drug have been reached. Experience with oral melphalan suggests that repeated courses should be given since improvement may continue slowly over many months, and the maximum benefit may be missed if treatment is abandoned prematurely.Other dosage regimens have been used by various investigators. Osserman and Takatsuki have used an initial course of 10 mg/day for 7 to 10 days. They report that maximal suppression of the leukocyte and platelet counts occurs within 3 to 5 weeks and recovery within 4 to 8 weeks. Continuous maintenance therapy with 2 mg/day is instituted when the white blood cell count is greater than 4000 cells/mcL and the platelet count is greater than 100,000 cells/mcL. Dosage is adjusted to between 1 and 3 mg/day depending upon the hematological response. It is desirable to try to maintain a significant degree of bone marrow depression so as to keep the leukocyte count in the range of 3000 to 3500 cells/mcL. Hoogstraten et al have started treatment with 0.15 mg/kg per day for 7 days. This is followed by a rest period of at least 14 days, but it may be as long as 5 to 6 weeks. Maintenance therapy is started when the white blood cell and platelet counts are rising. The maintenance dose is 0.05 mg/kg per day or less and is adjusted according to the blood count. One study by Alexanian et al has shown that the use of melphalan in combination with prednisone significantly improves the percentage of patients with multiple myeloma who achieve palliation. One regimen has been to administer courses of melphalan at 0.25 mg/kg per day for 4 consecutive days (or, 0.20 mg/kg per day for five consecutive days) for a total dose of 1 mg/kg per course. These four to five day courses are then repeated every 4 to 6 weeks if the granulocyte count and the platelet count have returned to normal levels. Response may be very gradual over many months; it is important that repeated courses or continuous therapy be given since improvement may continue slowly over many months, and the maximum benefit may be missed if treatment is abandoned too soon. Available evidence suggests about one third to one half of the patients with multiple myeloma show a favorable response to the drug.

Usual Adult Dose for Ovarian Cancer:

For use in the treatment of epithelial ovarian cancer:Common regimen: 0.2 mg/kg orally daily for 5 days as a single course. Courses are repeated every four to five weeks depending upon hematologic tolerance.

What other drugs will affect melphalan?

Before taking melphalan, tell your doctor if you are being treated with any other medicines that weaken your immune system, such as:

  • cyclosporine (Gengraf, Neoral, Sandimmune);

  • radiation therapy;

  • steroids (prednisone and others); or

  • another chemotherapy medicine.

This list is not complete and there may be other drugs that can interact with melphalan. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
