Alfa injections refer to a class of medications, not a single drug. Different "alfa" drugs have distinct uses. The most common examples are variations of epoetin alfa and darbepoetin alfa, used primarily to treat anemia.
Epoetin Alfa Injections
Epoetin alfa helps your body produce more red blood cells. This is crucial because red blood cells carry oxygen throughout your body and remove carbon dioxide. Therefore, epoetin alfa is used to treat anemia, particularly in patients with:
- Chronic kidney disease (CKD): Whether or not they are undergoing dialysis. (Mayo Clinic)
- Anemia related to chemotherapy: Reducing the need for blood transfusions. (MedlinePlus)
It's important to note that epoetin alfa may increase blood pressure, especially in patients with long-term kidney failure. (WebMD)
Darbepoetin Alfa Injections
Similar to epoetin alfa, darbepoetin alfa stimulates red blood cell production. It is used to treat anemia caused by:
- Chronic kidney disease (CKD): In patients both on and off dialysis. (Mayo Clinic, Aranesp)
- Chemotherapy: Specifically when chemotherapy is expected to be ongoing. (MedlinePlus)
Other Alfa Injections
Other medications ending in "-alfa" have different applications:
- Follitropin alfa: Used in fertility treatments to stimulate egg development in women with ovulation problems. (Mayo Clinic)
- Interferon alfa-2b: Used to treat various conditions including hepatitis B and C, certain cancers (lymphoma, malignant melanoma), genital warts, and hairy cell leukemia. (Mayo Clinic)
- Efgartigimod alfa: A component of VYVGART HYTRULO, used to treat generalized myasthenia gravis, a condition causing muscle weakness and fatigue.
