Lenalidomide Medications

Lenalidomide Info

What is Lenalidomide?

Lenalidomide is an immunomodulatory medicine that belongs to a class of drugs known as thalidomide analogues. It is designed to adjust the activity of the immune system and influence the growth of certain abnormal cells. In Hong Kong, lenalidomide is regulated by the Department of Health and is available only with a prescription from a qualified health professional. It appears in several branded and generic products that share the same active ingredient.

Medications with Lenalidomide

The ingredient lenalidomide is marketed under a few brand names, the most common being Revlimid. Generic versions also exist and are identified simply as lenalidomide tablets. These products are offered in strengths such as 5 mg, 10 mg, 15 mg and 25 mg, allowing doctors to tailor the dosage to each patient’s needs. In Hong Kong pharmacies, both brand-name and generic lenalidomide are dispensed under the same prescription requirements.

What Does Lenalidomide Treat?

Lenalidomide is approved to manage several blood-related disorders:

• Multiple myeloma - a cancer of plasma cells that can cause bone pain, anemia and kidney problems. Lenalidomide helps slow the growth of malignant cells.
• Myelodysplastic syndromes (MDS) with del(5q) - a condition where the bone marrow produces too few healthy blood cells. The drug can improve blood counts in many patients.
• Mantle cell lymphoma - a type of non-Hodgkin lymphoma that affects the lymph nodes and spleen. Lenalidomide may be used when other treatments have not succeeded.
• Chronic lymphocytic leukemia (CLL) - some treatment plans include lenalidomide for patients whose disease is progressing.

These uses are based on approvals from the Hong Kong Department of Health and reflect the drug’s ability to modify immune responses and reduce abnormal cell proliferation.

How Lenalidomide Works

Lenalidomide helps the body by tweaking how immune cells communicate and by stopping certain cancer-related cells from multiplying. It can increase the activity of natural killer cells, which are part of the body's own defense system, and reduce signals that tell abnormal cells to grow. Effects are usually noticed within a few weeks of starting therapy, although the exact timing varies from person to person.

Safety Information

Common Side Effects

• Mild fatigue or feeling unusually tired.
• Low-grade fever or chills.
• Nausea or occasional upset stomach.
• Minor rash or skin irritation.

These reactions are generally short-lived and may lessen as the body adjusts to the medication.

Serious Reactions

• Sudden shortness of breath, wheezing or swelling of the throat, which could signal a severe allergic response.
• Unexplained bruising, bleeding from the gums or prolonged nosebleeds, indicating a possible blood-related problem.
• Persistent fever, chills, or flu-like symptoms that do not improve.

If any of these occur, seek urgent medical attention.

Who Should Be Cautious

• People with a known allergy to lenalidomide or related thalidomide drugs.
• Individuals who are pregnant, planning to become pregnant, or may become pregnant, because lenalidomide can cause serious birth defects. In Hong Kong, strict pregnancy-prevention programmes are required for anyone taking this medicine.
• Patients with severe kidney or liver impairment should discuss special precautions with their health professional.

Interaction Awareness

• Medicines that affect the immune system, such as certain biologics or immunosuppressants, may interact with lenalidomide.
• Alcohol can increase the risk of liver-related side effects.
• Some antibiotics and antifungal agents may alter how lenalidomide is processed in the body.
