What is the emergency treatment of hemiplegic migraine?

Hemiplegic migraine requires prompt emergency management during acute attacks. This first-line protocol addresses parenteral treatment of the acute migraine episode.

The protocol centres on a parenteral approach: the first-choice treatment is administered intravenously, with an additional agent available for combined use where clinically appropriate. An alternative subcutaneous option is available when the primary approach is not indicated.

The complete protocol — specific agents, selection criteria, and dosing — is available via the structured regimen below.
