Summary for Rytelo

Prescription only

Rytelo (imetelstat) is used to treat a blood condition called myelodysplastic syndrome (MDS). It's for adults with lower-risk MDS who also have anemia and need regular red blood cell (RBC) transfusions. Rytelo (imetelstat) is typically used after erythropoiesis‑stimulating agents (ESAs) stop working, don’t work, or can’t be used. It's given as an intravenous (IV) infusion at a clinic once every 4 weeks. Each infusion takes about 2 hours, and you’ll get medications right before to lower the chance of infusion reactions. Common side effects include low platelets, low white blood cells, and feeling tired.
