Lenalidomide is used for treating multiple myeloma and myelodysplastic syndromes; it’s an immunomodulator, y’know? It’s part of those immunomodulatory drugs that mess with both your immune system and cancer cells. You can get it in capsule form, from 2.5 mg all the way up to 25 mg. The usual dose is 25 mg, taken every day for 21 days out of every 28-day cycle.
Each bottle has 21 capsules. How it works is by slowing down some enzymes, changing how these specific proteins that control cell growth and death are made. And it also messes with your immune system to help fight off cancer cells.
You might get side effects like anemia, low white cell count, low platelet count, tiredness, or swelling in your legs and feet. It can cause bad birth defects and mess with your fertility, for both men and women. You really need to stick to the dosage schedule to get the most out of the drug and keep risks low.
