Medications for multiple myeloma are used to treat this type of cancer. They work in various ways to target cancer cells. Some other medications help manage complications from the cancer and prepare the body for stem cell transplantation. Common classes include chemotherapy agents, immunomodulatory drugs, and proteasome inhibitors. Some chemotherapy agents, like cyclophosphamide and melphalan (Alkeran), can be taken orally or as injections. Immunomodulatory drugs, such as lenalidomide (Revlimid), are usually taken as oral pills. Proteasome inhibitors like bortezomib (Velcade) are given as injections. These options provide different ways to help manage multiple myeloma effectively.
