When other medications don’t manage migraine disease well enough, a doctor may suggest trying a CGRP blocker, given by infusion.
This means it’s administered through a needle into a vein.

CGRP blockers are available in other forms, but infusions have some potential advantages.
They make it possible for the medication to go directly into the bloodstream, so it can start working quickly.
Infusions are administered once every three months. Some people start having fewer migraine attacks almost immediately after starting infusions.
