Luspatercept — Uses, Dosage, Side Effects & Safety

Drug class: Erythroid maturation agent

Overview

Luspatercept is a prescription medicine used to treat anemia (low red blood cell count) in adults with certain blood disorders, such as beta thalassemia and myelodysplastic syndromes (MDS), especially when regular blood transfusions are needed. It works by helping the bone marrow produce more mature red blood cells, which can reduce the need for transfusions. Luspatercept is given as a subcutaneous injection, usually every three weeks. It is not a cure for these conditions but can help manage symptoms and improve quality of life. Patients should be aware of possible side effects and the need for regular monitoring while on this medication.
