Lenalidomide

Lenalidomide capsule What does this drug do? The immune system is affected by LENALIDOMIDE. It makes the immune system work better, which slows the growth of tumors. Lenalidomide is used to treat anemia (when the body doesn't have enough red blood cells), multiple myeloma (cancer caused by a blood disease that gets worse over time), and mantle cell lymphoma (a rare cancer of the lymph nodes). It is given to people who have myelodysplastic syndrome, which is caused by a chromosome that is not normal. Because part of chromosome 5 is missing, this disease is also called deletion 5q MDS. The bone marrow does not make enough healthy blood cells in people with this disease. If you have chronic lymphocytic leukemia (CLL), you shouldn't take lenalidomide unless you are in a controlled medical study. People with CLL are more likely to die from heart problems if they take lenalidomide. Lenalidomide can also be used for other things that aren't in this guide.
