What is Zarxio?

Zarxio (filgrastim-sndz) is employed for treating neutropenia (lack of white blood cells) when patients are taking certain chemotherapy drugs, going through a bone marrow transplant, or due to other ailments.Zarxio can be used to reduce the risk of contracting infection among those with non-myeloid-related cancer (cancer that doesn't involve bones marrow) or who are taking chemotherapy drugs that can reduce the amount of neutrophils (a blood type required to fight infections).

Zarxio is used in addition to aiding in increasing the amount of blood-forming white cells and reducing the duration of time that fever is present for patients suffering from chronic myeloid leukemia (AML, a kind of cancer affecting these white blood cells) that are being treated using chemotherapy drugs.

Zarxio is also prescribed to patients undergoing bone marrow transplants as well as those suffering from acute chronic neutropenia (a condition where there are very few neutrophils found in the blood).Zarxio can also be used in the preparation of blood to be used in leukapheresis (a procedure in which specific blood cells are eliminated from the body).

Filgrastim-sndz is part of a group of medicines known as colony-stimulating factors. It is a stimulant for the development of neutrophils, the type of white blood cells that play a crucial role in fighting infections.


Zarxio may result in serious lung problems known as acute respiratory distress syndrome (ARDS) as well as an uncommon but severe consequence called capillary leak syndrome. Call your doctor or get medical emergency attention promptly if you notice symptoms of fever and breathing problems, including shortness of breath, fast breathing, nasal congestion or dryness, fatigue, decreased thirst, and sudden swelling and the weight of your body.

Zarxio may cause the spleen to be large and bloated, which can cause it to break (tear). Call your physician immediately if you are experiencing abdominal pain on the left side or shoulder pain.
