About GRANIX
What is this medication? Granix, which contains the active ingredient tbo-filgrastim, is a prescription medication classified as a leukocyte growth factor. It is primarily used to reduce the duration of severe neutropenia in patients with non-myeloid cancers who are undergoing chemotherapy. Neutropenia is a condition characterized by low levels of neutrophils, which are a type of white blood cell essential for fighting infections. By shortening the time these levels are dangerously low, the medication helps decrease the risk of infection-related complications during cancer treatment.
The medication works by stimulating the bone marrow to produce more neutrophils, thereby boosting the body's immune system defense. It is typically administered via an injection starting shortly after a chemotherapy cycle. Granix is approved for use in both adults and pediatric patients who are at least one month old. It is specifically intended for those receiving myelosuppressive anticancer drugs that are known to cause a significant decrease in white blood cell counts.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
