Lenalidomide is a drug that is very similar to thalidomide, which is known to cause severe birth defects or death in unborn babies. If lenalidomide is taken during pregnancy, it may also cause severe birth defects or death in unborn babies. Therefore, this drug must never be used during pregnancy nor by women who could become pregnant while using this drug. Women must have two negative pregnancy tests before starting lenalidomide, the first 10-14 days before the first dose and the second within 24 hours before the first dose. Women must also continue to have pregnancy tests regularly during treatment (see also Notes section).
To receive this medication, all doctors, pharmacists, and patients must understand, agree to, and carefully follow the requirements of the Revlimid REMS Program (formerly known as the RevAssist program) developed by the U.S. Food and Drug Administration. These requirements apply in the United States. If you live in Canada or any other country, consult your doctor and pharmacist for your country's regulations.
If lenalidomide is used in a child between ages 12 to 18 years, a parent or legal guardian must also read the educational material and agree to carefully follow the requirements of the Revlimid REMS program.
Men or women who use this medication must use two reliable forms of birth control. For males, this means using a latex condom along with other effective birth control used by the female partner. If pregnancy does occur during treatment, stop this medication and contact your doctor immediately. (See also Precautions section.)
Lenalidomide may benefit you by helping increase the number of functioning red blood cells. However, it may also increase your risk of developing serious bone marrow problems such as low white blood cell counts or low platelet counts. Seek immediate medical attention if you develop the following symptoms: persistent fever, persistent sore throat, easy bleeding/bruising. Most patients will experience these effects, which will require your doctor to stop and restart lenalidomide or decrease your dose.
Lenalidomide can cause serious (sometimes fatal) blood clots in veins and lungs. Get medical help right away if you develop the following symptoms: calf pain/swelling/warmth, chest pain, trouble breathing.Who should not take lenalidomide?
This medication is used to treat anemia in patients with certain blood/bone marrow disorders (myelodysplastic syndromes-MDS). These patients do not have enough properly working red blood cells and often require blood transfusions to reverse their anemia. Lenalidomide may lessen the need for blood transfusions. This medication may also be used to treat certain cancers (multiple myeloma, mantle cell lymphoma-MCL).
Lenalidomide is not recommended for the treatment of a certain type of cancer (chronic lymphocytic leukemia) because of the increased risk of serious heart-related side effects and death. If you have this type of cancer, talk to your doctor about the risks of using this medication.
Lenalidomide is a type of drug known as an immunomodulator. It is believed to work by decreasing the immune system's response, thereby lowering the number of working red blood cells that are destroyed naturally by the body.
