Dargen 40 Injection Pfs 0.4 ml is primarily used to treat anaemia (low red blood cell count) in patients with long-term serious (chronic) kidney disease and those receiving chemotherapy for certain types of cancer (aside from bone marrow or blood cells' cancer). Anemia can be treated with Dargen 40 Injection (0.4 ml), which also lessens the requirement for blood transfusions. When the body's supply of red blood cells or haemoglobin is low, anaemia results. Anaemia is caused by damaged kidneys that are unable to filter the blood in chronic renal disease. The protein "Darbepoetin alfa" found in Dargen 40 Injection 0.4 ml works by sending instructions to the bone marrow to produce more red blood cells.Disclaimer:For more information contact your physician.
