Fremanezumab plus plasmapheresis in a patient with chronic migraine and myasthenia gravis: Case report of an effective treatment

A patient with chronic migraine and generalized myasthenia gravis was concurrently treated with fremanezumab and with therapeutic plasmapheresis (PEX). Fremanezumab was dosed right after a PEX session, or in the midpoint between sessions, and the efficacy of both treatments was maintained. This case broadens the drug's clinical applications and it helps in choosing the appropriate medical regimen in patients requiring both treatments.
