The way Kevzara and Actemra work is basically the same. They are classified the same … both are IL-6 receptor blockers.

The chemical structure of Actemra and Kevzara are different so they aren’t identical medications. They work basically the same way. There might be subtle differences but I don’t think one is any better than the other.

The biggest difference is Actemra is FDA approved for GCA and not for PMR.
Kevzara is FDA approved for PMR.

My rheumatologist thinks either medication should work for both PMR and GCA.
