One note. This label lists polysorbate. In pharmaceutical use it is most often made from plant sources, but this label does not state the source. We have not confirmed the source with the maker.

This medicine is a biologic. It is produced by cells grown in culture (a hamster-cell line is standard for this class). No animal-derived ingredient is listed among its inactive ingredients. Manufacturing inputs beyond the label are a question for the manufacturer; we note it because the label cannot show them.
