Several medications stimulate the production of red blood cells (RBCs), primarily used to treat anemia (low RBC count). These drugs work by mimicking or enhancing the body's natural processes.
Erythropoiesis-Stimulating Agents (ESAs)
-
Erythropoietin (EPO): This hormone naturally produced by the kidneys stimulates RBC production in the bone marrow. Synthetic versions, like epoetin alfa (Procrit®, Epogen®) and darbepoetin alfa (Aranesp®), are commonly prescribed to treat anemia associated with chronic kidney disease, cancer chemotherapy, and other conditions. These are administered via injection. [Source: NYU Langone Health, Cleveland Clinic, Procrit.com, Aranesp.com, Medical News Today]

Mechanism of Action: ESAs bind to receptors in bone marrow cells, triggering increased production and maturation of RBCs. [Source: Medical News Today]
Other Medications that May Indirectly Increase RBCs
While not directly stimulating RBC production like ESAs, some medications can indirectly lead to an elevated RBC count:
-
Anabolic Steroids: These drugs can increase RBC production, though this is often an unintended side effect and carries significant health risks. [Source: Mayo Clinic]
-
Certain Medications with Side Effects: Some drugs, such as some antibiotics (chloramphenicol), hydantoins, and methyldopa, can incidentally raise RBC counts as a side effect. [Source: UF Health]
It's crucial to understand that increasing red blood cell count isn't always desirable. High RBC count (polycythemia) can be a serious medical condition. Treatment for low RBC counts should always be guided by a physician.
