Zarxio (Filgrastim-sndz) is used to treat neutropenia. Zarxio is a biosimilar for neupogen (filgrastim). Biosimilars are biologic drugs that are similar to the original medication with no meaningful differences in effectiveness or safety. Zarxio may be covered by your Medicare or insurance plan, but some pharmacy coupons or cash prices could help offset the cost.

With the Patient Assistance Program from Novartis, you can receive your medication at no cost.
