Which non-drug option provides rapid relief for acute cluster headache?

High-flow oxygen therapy is the rapid, non-drug option for aborting an acute cluster headache. Inhaling 100% oxygen at high flow through a tight-fitting mask often relieves pain within about 15 minutes by dampening the cranial vasodilation and trigeminal pain signaling that drive the attack, all without systemic medication. It’s safe, easy to administer at home, and avoids drug-related side effects, making it the preferred non-pharmacologic rescue therapy for an acute cluster headache. The other options involve medications—sumatriptan and zolmitriptan are fast-acting abortives delivered as injections or sprays, and caffeine lacks consistent, rapid efficacy for this condition—so they’re not the non-drug choice for quick relief.
