Substitutes for ZARXIO primarily include other brand-name versions of filgrastim and its generic form, as ZARXIO itself is a biosimilar to the original filgrastim product.
ZARXIO is a biosimilar to filgrastim, a crucial medication used to stimulate the production of white blood cells (specifically neutrophils) in the bone marrow. This increase in white blood cells is often vital for patients undergoing certain medical treatments like chemotherapy, those with severe chronic neutropenia, or individuals preparing for stem cell transplantation. Therefore, any other product containing filgrastim can serve as a substitute.
Common Substitutes for ZARXIO
Several other formulations and brand names of filgrastim are available as alternatives to ZARXIO. These are all injectable solutions of filgrastim.
| Brand Name | Active Ingredient | Type | Notes |
|---|---|---|---|
| Neupogen | Filgrastim | Original Brand | The first approved filgrastim product. |
| Nivestym | Filgrastim | Biosimilar | A biosimilar alternative to Neupogen. |
| Nypozi | Filgrastim | Biosimilar | Another biosimilar option. |
| Releuko | Filgrastim | Biosimilar | A further biosimilar available. |
| Generic Filgrastim | Filgrastim | Generic | The unbranded version, often a more cost-effective choice. |
These options provide flexibility for healthcare providers and patients, allowing for choices based on availability, cost, or specific patient needs. It's important to note that while biosimilars like ZARXIO are highly similar to their reference product (Neupogen) with no clinically meaningful differences in terms of safety, purity, and potency, any switch between products should always be done under the guidance of a healthcare professional.
