Lenalid Lenalidomide 15 Mg Capsules

Q1: What is Lenalidomide 15mg used for?

Lenalidomide 15mg is used for multiple myeloma (intermediate dosing), mantle cell lymphoma as a starting dose, and for patients with moderate renal impairment (eGFR 30–59 ml/min) who cannot tolerate the full 25mg dose.

Q2: How does Lenalidomide 15mg differ from 10mg and 25mg?

15mg is an intermediate dose used when 10mg provides insufficient efficacy but 25mg causes excessive toxicity. It is also a specific renally adjusted dose for patients with moderately impaired kidney function.

Q3: What is the dosing schedule for Lenalidomide 15mg?

For multiple myeloma: 15mg once daily on Days 1–21 of a 28-day cycle with dexamethasone. For mantle cell lymphoma: 15mg once daily on Days 1–21 of a 28-day cycle. Continuous daily dosing may apply for some indications.

Q4: How does Lenalidomide work at the cellular level?

Lenalidomide binds cereblon (CRBN), an E3 ubiquitin ligase component, triggering targeted degradation of IKZF1 and IKZF3 — transcription factors essential for myeloma and lymphoma survival. It also enhances T-cell and NK cell anti-tumor activity.

Q5: What REMS requirements apply to 15mg?

All REMS requirements are identical across all Lenalidomide doses. Mandatory pregnancy prevention, monthly pregnancy testing, and REMS-authorized dispensing apply equally to the 15mg capsules.

Q6: What are the most common side effects?

Common side effects include anemia, neutropenia, constipation, diarrhea, nausea, and back pain. At 15mg, these are usually less severe than at 25mg but regular monitoring is still essential.

Q7: What serious side effects require urgent attention?

Stevens-Johnson syndrome (severe blistering skin rash), tumor lysis syndrome (sudden metabolic changes), cardiac events, pulmonary embolism, or severe hepatic failure require immediate emergency care.

Q8: What blood clot prevention is required?

Thromboprophylaxis is mandatory at all Lenalidomide doses. Aspirin is used for low-risk patients; low molecular weight heparin or warfarin for high-risk patients. Risk is not reduced by using the 15mg dose.

Q9: What monitoring is needed during treatment?

Weekly CBC for 8 weeks then monthly, plus regular renal function monitoring (every 3 months), liver function tests, and clinical assessment for VTE or skin reactions.

Q10: Is Lenalidomide 15mg safe in pregnancy?

No. Lenalidomide at any dose is absolutely contraindicated in pregnancy. It is a teratogen with a mandatory REMS program regardless of dose strength.

Q11: How should Lenalidomide 15mg be stored?

Store below 25°C in original child-resistant packaging, away from moisture. Unused capsules must be returned to the dispensing pharmacy — do not dispose in household waste.

Q12: Is a prescription required?

Yes. Lenalidomide requires oncologist prescribing and REMS-compliant pharmacy dispensing at all strengths, including 15mg.
