Lenalid Capsule (Lenalidomide) | Used for Treatment of Multiple Myeloma and Blood Cancers
Lenalid Capsule (Lenalidomide) is a medicine used to treat multiple myeloma and certain blood cancers like myelodysplastic syndromes. Lenalid capsule is an immunomodulating agent that affects the working of the immune system to help the bone marrow in making new & normal blood cells & erasing the abnormal cells from the bone marrow.Revlimid is another trade name for Lenalid.
Product Overview
Lenalid Capsule contains Lenalidomide, a potent immunomodulatory and anti-neoplastic agent structurally related to thalidomide. Lenalid Capsule is used in the treatment of specific blood cancers and related conditions, functioning primarily by modulating the immune system and inhibiting the growth of abnormal cells. Due to its significant risk of severe birth defects, this medication is strictly controlled and must be used under rigorous medical supervision and within mandated safety programs.
Product Composition
- Active Ingredient: Lenalidomide (available in various strengths, 5 mg, 10 mg, 15 mg & 25 mg).
- Excipients: Anhydrous lactose, microcrystalline cellulose, croscarmellose sodium, and magnesium stearate. (Always refer to the specific package insert for exact excipient composition).
Product Specification
| Feature | Details |
| Brand Name | Lenalid Capsule |
| Active Ingredient | Lenalidomide |
| Therapeutic Category | Immunomodulatory / Antineoplastic Agent |
| Form | Oral Capsule |
| Primary Indications | Multiple Myeloma, Myelodysplastic Syndromes (MDS), Mantle Cell Lymphoma |
| Storage Requirements | Room temperature, protected from moisture and light |
Mechanism of Action
- Immunomodulation: Lenalidomide stimulates the activity of T-cells and natural killer (NK) cells, which helps the immune system recognize and attack malignant cells.
- Anti-Angiogenesis: It suppresses the formation of new blood vessels that tumors require to grow and spread, effectively "starving" the cancer.
- Direct Anti-Tumor Effects: It binds to the protein cereblon, which leads to the degradation of specific transcription factors essential for the survival of myeloma cells, ultimately inducing cell death (apoptosis).
Key Benefits & Indications
- Multiple Myeloma: A cornerstone treatment, often used in combination with dexamethasone, to manage the disease and extend progression-free survival.
- Myelodysplastic Syndromes (MDS): Specifically indicated for patients with transfusion-dependent anemia due to low- or intermediate-risk MDS associated with a deletion 5q cytogenetic abnormality.
- Mantle Cell Lymphoma (MCL): Used in patients whose disease has relapsed or progressed after other prior therapies.
CRITICAL SAFETY WARNING: PREGNANCY
Lenalidomide is a potent teratogen and is strictly contraindicated during pregnancy. Exposure at any time can cause severe, life-threatening birth defects or fetal death.
- Mandatory Enrollment: Patients must be enrolled in a strictly regulated risk management program (e.g., REMS) to receive this medication.
- Contraceptive Protocols: Women of childbearing potential must use two highly effective, concurrent methods of contraception for at least 4 weeks before, during, and until 4 weeks after completion of therapy.
- Male Patients: Lenalidomide is present in semen. Male patients must use condoms during any sexual contact with women of childbearing potential for the duration of therapy and for 4 weeks after stopping the medication.

Safety Precautions
Pregnancy Warning: This drug is a potent teratogen and is strictly contraindicated for pregnant women. Women must use two highly effective, concurrent forms of contraception, and men must use condoms during all sexual contact to prevent fetal exposure.
Blood Clot Monitoring: There is an increased risk of venous thromboembolism (blood clots). Seek immediate medical attention for symptoms such as chest pain, shortness of breath, or sudden swelling/pain in the legs.
Myelosuppression: Lenalidomide can significantly lower blood cell counts. Watch for signs of infection (fever, chills), unusual bruising or bleeding, and extreme fatigue. Regular blood tests are mandatory.
Handling & Storage: Store at room temperature in a cool, dry place. Keep out of the reach of children. If the powder from a broken capsule contacts your skin, wash the area thoroughly with soap and water.

FAQs
Q: What is Lenalid (Lenalidomide) used for?
A: It is a cancer medication used primarily to treat Multiple Myeloma, certain types of Myelodysplastic Syndromes (MDS) with specific genetic abnormalities, and relapsed Mantle Cell Lymphoma.
Q: Why is it strictly controlled?
A: Lenalidomide is chemically related to thalidomide and is a potent teratogen. It can cause severe, life-threatening birth defects if taken during pregnancy. Therefore, it is only available through strict, mandatory risk management programs.
Q: Do men need to worry about the pregnancy risks?
A: Yes. Lenalidomide is present in the semen of men taking the drug. Male patients must use a condom during sexual contact with women of childbearing potential, even if they have had a vasectomy, and must not donate sperm during treatment or for 4 weeks after stopping.
Q: What are the most common side effects?
A: Common side effects include fatigue, diarrhea, constipation, itching, rash, and nausea. It can also significantly lower blood cell counts, increasing the risk of infections, anemia, and bleeding.
Q: Can I take this with other medications?
A: Lenalidomide can interact with various drugs. Always provide your healthcare team with a complete list of all prescription drugs, over-the-counter medications, vitamins, and herbal supplements you are taking.
Q: Why do I need frequent blood tests?
A: Because Lenalidomide often lowers white blood cell and platelet counts, your doctor must monitor your blood regularly. These tests ensure your counts are safe and allow for dose adjustments if necessary.
Q: Is there an increased risk of blood clots?
A: Yes, there is an increased risk of deep vein thrombosis (DVT) and pulmonary embolism. Your doctor may prescribe blood thinners or aspirin as a preventative measure while you are on this medication.
Q: What should I do if I miss a dose?
A: If you miss a dose and it has been less than 12 hours, take it as soon as you remember. If it has been more than 12 hours, skip the missed dose and resume your regular schedule. Never take two doses at once to make up for a missed one.
Q: How should the capsules be handled?
A: Always handle the capsules carefully. Do not break or open them. If you touch the powder inside a broken capsule, wash the area thoroughly with soap and water.
Q: Can I donate blood while on this treatment?
A: No. You must never donate blood or plasma while taking Lenalidomide or for at least 4 weeks after stopping, as the drug could potentially be passed to a recipient.
