You may be familiar with some common biologics, such as Botox, insulins, and vaccines. Biosimilars are somewhat like a generic version of biosimilars. A biosimilar is highly similar to the original biologic. Since they’re not a carbon copy, they’re not called generics.

In this video, learn what biosimilars are (and how they’re different from generic medications), according to Stacia Woodcock, PharmD, Pharmacy Editor at GoodRx, and Alyssa Billingsley, PharmD, Director of Pharmacy Content at GoodRx.
