Grastim 300 mcg Injection 1 ml belongs to the class of medicine called 'hematopoietic agent' used to treat neutropenia, a lack of certain white blood cells caused by cancer, bone marrow transplant, receiving chemotherapy, bacterial infections or other conditions. Neutropenia is a condition in which the number of neutrophils (a type of white blood cell) in the blood is decreased. White blood cells (neutrophils) protect the body from infections. Without enough neutrophils, the body can not fight off bacteria which increases the risk of many types of infections.

Grastim 300 mcg Injection 1 ml contains ' Filgrastim ' that stimulates the bone marrow (the tissue where new blood cells are made) to produce more white blood cells that help fight infection. Grastim 300 mcg Injection 1 ml is used to improve white blood cells during cancer treatment (chemotherapy), bone marrow transplantation, severe chronic neutropenia (low number of a type of white blood cells), neutropenia in patients with HIV infection, and before stem cell donation.

Neutropenia is a condition in which the number of neutrophils (a type of white blood cell) in the blood is decreased. White blood cells (neutrophils) protect the body from infections. Without enough neutrophils, the body can not fight off bacteria which increases the risk of many types of infections. It can be caused by diseases that damage the bone marrow like cancer chemotherapy, HIV or AIDS, infections or deficiencies in vitamins or minerals, such as vitamin B12, folate, or copper, and autoimmune diseases, including Crohn's disease, lupus, and rheumatoid arthritis. Severe chronic neutropenias arise from the failure of the bone marrow to produce adequate numbers of neutrophils that circulate in the blood. It appears that patients with severe chronic neutropenias are at greater risk of developing leukaemia (blood cancer) than are other people.
