Legal status by country
Is CGRP legal?
Written by Aaron CuhaReviewed Sep 2026
How CGRP is classified in the United States, United Kingdom, Australia and Canada, side by side. Each country has its own page with a direct answer, the regulator's approval status and what the classification means in practice.
All four countries, side by side
| Attribute | United States · FDA | United Kingdom · MHRA | Australia · TGA | Canada · Health Canada |
|---|---|---|---|---|
| Status | Not approved | Not approved | Not approved | Not approved |
| Classification | Not a medicine; endogenous signalling molecule | Not a medicine; endogenous signalling molecule | Not a medicine; endogenous signalling molecule | Not a medicine; endogenous signalling molecule |
| Note | CGRP is a peptide the body produces and is not a product. The approved medicines acting on this pathway all block it: erenumab, fremanezumab, galcanezumab and eptinezumab (antibodies) and the gepants ubrogepant, rimegepant, atogepant and zavegepant. None of them is CGRP. | The same CGRP-directed antibodies and gepants are licensed by the MHRA. The peptide itself is not a medicinal product. | CGRP-directed migraine medicines are TGA-registered. The peptide itself is not a therapeutic good. | CGRP-directed migraine medicines are authorised by Health Canada. The peptide itself is not a drug product. |
US FDA status: CGRP itself is an endogenous peptide and is not a medicine, so it has no FDA status. Multiple drugs targeting it are FDA-approved: the monoclonal antibodies erenumab, fremanezumab, galcanezumab and eptinezumab, and the oral receptor antagonists known as gepants, including ubrogepant, rimegepant, atogepant and zavegepant. Those approvals belong to those molecules and describe blocking CGRP, not administering it.. Reviewed Sep 2026.
