Colstim 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.

Colstim 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. Colstim 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.

You are advised to take Colstim Injection 1 ml for as long as your doctor has prescribed it for you, depending on your medical condition. In some cases, you may experience certain common side effects such as thrombocytopenia (low platelets level), anaemia (low red blood cell), headache, diarrhoea, vomiting, nausea, alopecia (unusual hair loss), tiredness, soreness, swelling of the digestive tract, fever. Most of these side effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side effects persistently.

Regular blood tests will be taken to monitor the number of white blood cells in the body. Inform your doctor about your health condition and medicines to rule out unpleasant side effects.

Do not store in the freezer or the fridge.

Colstim Injection 1 ml contains ‘Filgrastim’ is a white blood cell growth factor. It belongs to a group of proteins called cytokines and is very similar to a natural protein (granulocyte-colony stimulating factor) produced by your body. Colstim Injection 1 ml works by stimulating the bone marrow (the tissue where new blood cells are made) to produce more white blood cells that help fight infection. Colstim 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.

Drug-Food Interaction: Avoid alcohol consumption while taking Colstim Injection 1 ml as it may increase dizziness and side effects.

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.
