The FDA has approved Rezvoglar, the second interchangeable biosimilar for Lantus (insulin glargine); the first was Semglee.
What is a biosimilar? It’s kind of like a generic drug, but in the case of biologics, it has to be highly similar and have no clinically-meaningful differences.

@rchusid That is an excellent question.
For generics, the more there are, the more the price is driven down.
From the FDA, looking at average manufacturer prices reported to CMS:
1 generic: 39% lower than the brand name drug
2 generics: 54% lower
4 generics: 79% lower
6+ generics: 95+% lower

I imagine (and hope!) that this would be the same for biosimilars.
@NeuroDrugDoc thank you for sharing this and other meds info.
do you have a trusted source where we can compare mer with biosimilars? kind of like on car shopping site where you have side by side for features etc?
oh thank you 🥰. it's not looking like it's designed for mobile so will try on desktop.
thank you for jump starting me on trying to understand #biologic v. #biosimilar
