Background and Date of Approval

Peglylated granulocyte colony-stimulating factor consists of the active ingredient Peglylated granulocyte colony-stimulating factor. This is synthesized from the bacteria E.coli. It belongs to a category of proteins called cytokines and is similar to the natural protein produced by the body. It is a leucocyte growth factor indicated to reduce infections in patients receiving anti-cancer drugs with bone marrow suppressive properties. Peglylated granulocyte colony-stimulating factor was approved by the US Food and Drug Administration (FDA) on February 20, 2002, for reducing the incidence of infection, as manifested by febrile neutropenia (decreased white blood cell count).

Mechanism of Action of undefined

The therapeutic effect of the Peglylated granulocyte colony-stimulating factor is to stimulate the production of neutrophils in the bone marrow. Neutrophils are a type of white blood cell that help to fight infections. Chemotherapy drugs can cause damage to the bone marrow, leading to a decrease in the number of neutrophils, which can increase the risk of infections. So this medication works by stimulating the bone marrow to produce more neutrophils, which can help prevent infections in cancer patients undergoing chemotherapy. This can reduce the risk of infections, hospitalizations, and other complications associated with chemotherapy-induced neutropenia.

Uses of undefined

Pegylated granulocyte colony-stimulating factor is used for patients with chemotherapy-induced neutropenia, chemotherapy-induced fever, and chemotherapy-induced infections.

undefined Drug administaration and Dosage available

Peglylated granulocyte colony-stimulating factor is administered as an injection under the skin. The injection should be given in the abdomen (at least 2 inches away from the belly button), the front of the thighs, or the upper arm. It is usually administered once per chemotherapy cycle. The medication should be administered at least 24 hours after the last dose of chemotherapy to allow for proper bone marrow recovery.

Warnings, Precautions and Side Effects of undefined


Rare cases of splenic rupture have been reported in patients receiving Peglylated granulocyte colony-stimulating factor. In rare cases, this medication can cause ARDS, a serious lung condition that can cause shortness of breath, coughing, and fatigue. Patients should notify their healthcare provider immediately if they experience any symptoms of ARDS. It can cause allergic reactions in some patients, which can be severe or life-threatening.

You should notify your healthcare provider immediately if these symptoms occur. Patients should tell the healthcare provider immediately if they experience any symptoms of ARDS. you require close monitoring for signs of an allergic reaction, such as rash, itching, or swelling. Patients with sickle cell disease also required close monitoring during treatment.

Side Effects
