Non-oral routes are preferred in the ED when rapid relief is needed and oral medicines may be unreliable due to vomiting or poor absorption. Subcutaneous sumatriptan or intranasal sumatriptan reach the bloodstream quickly without going through the GI tract, providing fast abortive relief for acute migraine. If a patient does not respond to triptans or the migraine is particularly severe or refractory, intravenous dihydroergotamine offers another mechanism of action and can be effective in stopping the attack in the ED setting, though it requires monitoring for vasoconstrictive effects.

Oral acetaminophen alone is often insufficient for moderate to severe migraines and does not guarantee rapid relief. Intravenous morphine is not ideal for acute migraine because it treats pain but carries risks and does not specifically target migraine pathophysiology, and it can complicate management and recovery.

So the best answer centers on using non-oral therapies like subcutaneous or intranasal sumatriptan, with IV dihydroergotamine as an option in refractory cases.
