Melphalan is in a class of medications called alkylating agents. It works by stopping or slowing the growth of cancer cells in your body.
Your doctor may need to delay your treatment or adjust your dose of melphalan depending on your response to treatment and any side effects that you experience. Talk to your doctor about how you are feeling during your treatment. Do not stop taking melphalan without talking to your doctor.
