Grafeel 300 mcg Injection is a medication that contains the active ingredient Filgrastim, a human granulocyte colony-stimulating factor (G-CSF) analog. It stimulates the growth of white blood cells to help reduce the likelihood of infection in patients undergoing chemotherapy for cancer. It is important to note that patients with blood disorders should not use this medicine. Grafeel 300 mcg Injection is available only by prescription and can be found at leading pharmacies and medical supply stores. Manufactured by Dr. Reddy’s Laboratories Ltd., Filgrastim is the generic name for Grafeel 300 mcg Injection, which is equivalent to the USA brand Neupogen. Grafeel 300 mcg Injection is used in the treatment of neutropenia caused by chemotherapy, bone marrow transplantation, peripheral progenitor cell transplantation, chronic neutropenia, and neutropenia due to radiation. Filgrastim works by stimulating the bone marrow to produce white blood cells that protect the body from infections. It is produced through recombinant DNA technology and controls the proliferation of committed progenitor cells, influencing their maturation into neutrophils.
