Lenalidomide treats myelodysplastic syndrome, conditions that interfere with the ability of bone marrow to make healthy blood cells. It is also used to treat multiple myeloma and mantle cell lymphoma.
Lenalidomide is a prescription medication used to treat myelodysplastic syndrome (MDS, bone marrow that does not produce enough mature blood cells). Lenalidomide is also used to treat multiple myeloma and mantle cell lymphoma (MCL).
Lenalidomide belongs to a group of drugs called immunomodulary agents. It works by helping the bone marrow produce normal blood cells and killing abnormal cells in the bone marrow.
This medication comes in capsule form. It is usually taken once daily, with water. Swallow lenalidomide capsules whole.
Common side effects include diarrhea, itching, and rash.

Uses of Lenalidomide
Lenalidomide is a prescription medicine used to treat certain patients who have myelodysplastic syndromes (MDS), specifically for the type of MDS with a chromosome problem where part of chromosome 5 is missing. This type of MDS is known as deletion 5q MDS and requires blood transfusions.
Lenalidomide is also used with dexamethasone to treat people with multiple myeloma.
Lenalidomide is also approved to treat those with multiple myeloma after autologous stem cell transplant (a type of stem cell transplant that uses your own stem cells).
This medication is also used to treat patients with mantle cell lymphoma (MCL) whose disease has relapsed or worsened after two prior therapies, one of which included bortezomib (Velcade).
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using lenalidomide.

Lenalidomide FDA Warning
WARNING: FETAL RISK, HEMATOLOGIC TOXICITY, and DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM
Do not use lenalidomide during pregnancy. Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study. Thalidomide is a known human teratogen that causes severe life-threatening human birth defects. If lenalidomide is used during pregnancy, it may cause birth defects or death to a developing baby. In women of childbearing potential, obtain 2 negative pregnancy tests before starting lenalidomide treatment. Women of childbearing potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after lenalidomide treatment. To avoid fetal exposure to lenalidomide, lenalidomide is only available under a restricted distribution program called “Revlimid REMS” .
Information about the Revlimid REMS program is available at www.celgeneriskmanagement.com or by calling the manufacturer’s toll-free number 1-888-423-5436.
Hematologic Toxicity (Neutropenia and Thrombocytopenia) lenalidomide can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with del 5q myelodysplastic syndromes had to have a dose delay/reduction during the major study. Thirty-four percent of patients had to have a second dose delay/reduction. Grade 3 or 4 hematologic toxicity was seen in 80% of patients enrolled in the study. Patients on therapy for del 5q myelodysplastic syndromes should have their complete blood counts monitored weekly for the first 8 weeks of therapy and at least monthly thereafter. Patients may require dose interruption and/or reduction. Patients may require use of blood product support and/or growth factors.
Deep Vein Thrombosis and Pulmonary Embolism lenalidomide has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients with multiple myeloma who were treated with lenalidomide and dexamethasone therapy. Patients and physicians are advised to be observant for the signs and symptoms of thromboembolism. Patients should be instructed to seek medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. It is not known whether prophylactic anticoagulation or antiplatelet therapy prescribed in conjunction with lenalidomide may lessen the potential for venous thromboembolic events. The decision to take prophylactic measures should be done carefully after an assessment of an individual patient’s underlying risk factors.
