Melphalan (Oral)

Generic name: Melphalan
Drug class: Alkylating agents

Usage of Melphalan (Oral)

Melphalan belongs to the group of medicines called alkylating agents. It is used to treat cancer of the ovaries and a certain type of cancer in the bone marrow.

Melphalan interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by melphalan, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects may not be serious but may cause concern. Some effects may not occur for months or years after the medicine is used.

Before you begin treatment with melphalan, you and your doctor should talk about the good this medicine will do as well as the risks of using it.

Melphalan is available only with your doctor's prescription.

The exact amount of medicine you need has been carefully worked out. Taking too much may increase the chance of side effects, while taking too little may not improve your condition.

Melphalan is sometimes given together with certain other medicines. If you are using a combination of medicines, it is important that you receive each one at the proper time. If you are taking some of these medicines by mouth, ask your health care professional to help you plan a way to remember to take your medicine at the right times.

While you are using melphalan, your doctor may want you to drink extra fluids so that you will pass more urine. This will help prevent kidney problems and keep your kidneys working well.

This medicine may cause nausea, vomiting, and loss of appetite. However, it is very important that you continue to receive the medicine, even if you begin to feel ill. Ask your health care professional for ways to lessen these effects.

If you vomit shortly after taking a dose of melphalan, check with your doctor. You will be told whether to take the dose again or to wait until the next scheduled dose.

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

Warnings

It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly and to check for unwanted effects.

While you are being treated with melphalan, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. Melphalan may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take or should not have taken oral polio vaccine within the last several months since there is a chance they could pass the polio virus on to you. Also, avoid other persons who have taken oral polio vaccine. Do not get close to them and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.

Melphalan can lower the number of white blood cells in your blood temporarily, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in urine or stools; or pinpoint red spots on your skin.

Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.

Do not touch your eyes or the inside of your nose unless you have just washed your hands and have not touched anything else in the meantime.

Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.

Avoid contact sports or other situations where bruising or injury could occur.
