A headache duration of 4–72 hours (in adults) when left untreated or unsuccessfully treated is one of the four core diagnostic criteria for migraine without aura, as defined by the International Headache Society (ICHD-3). Alongside unilateral location, pulsating quality, moderate-to-severe intensity, and associated nausea or photophobia/phonophobia, this temporal pattern distinguishes migraine from tension-type headache (which may last 30 minutes to 7 days but lacks associated features) and cluster headache (15 minutes to 3 hours). Understanding this criterion helps in self-identification and clinical diagnosis. The headache phase is one of four migraine phases: prodrome, aura (in migraine with aura), headache, and postdrome.

The Evidence
What the research says about headache lasting 4–72 hours, its role in migraine identification, and how it is managed.
A defining feature of migraine with strong clinical grounding
A headache lasting 4–72 hours when untreated is one of four core ICHD-3 criteria for migraine without aura. This time-course pattern is well-established in research and helps distinguish migraine from other headache types.
A sudden, severe 'thunderclap' headache may indicate subarachnoid haemorrhage — seek emergency care immediately. Headache with fever, neck stiffness, or rash may suggest meningitis. New headache in someone over 50, or headache with progressive neurological symptoms or vision loss, requires prompt professional assessment.
The ICHD-3 classification is the global standard for headache disorders, and the 4–72 hour window is well-established as a distinguishing feature of migraine. Several acute care approaches — including triptans and NSAIDs — have good evidence for shortening attack duration. CGRP antagonists are newer agents with a growing but still-developing evidence base, and evidence varies by agent.
Migraine without aura requires at least five attacks meeting criteria for duration, location, quality, intensity, and associated symptoms. Duration alone does not confirm migraine. A qualified healthcare professional should assess the full picture, particularly for new, changing, or frequent headaches. NICE guidelines support a stratified approach to both acute and preventive management.
Opioids are not recommended for migraine — they can worsen central sensitisation and increase the risk of medication overuse headache. Triptans are not appropriate for haemiplegic or basilar migraine, or for people with significant cardiovascular conditions. Butterbur, sometimes used traditionally for migraine, carries hepatotoxicity concerns and should be used only under professional guidance.
Acupuncture has moderate evidence for migraine prevention, recognised in both NICE and AHS frameworks. Magnesium supplementation has evidence for both prevention and acute support in migraine specifically. Riboflavin (B2) shows preventive benefit in some studies. For each of these, evidence quality differs, and NICE and AHS guidance positions them as adjuncts to — not replacements for — a professionally assessed migraine management plan.
If headaches occur more than four days per month, significantly affect daily life, or are not responding to over-the-counter options, a healthcare professional can assess suitability for preventive strategies. Overuse of acute pain relief on ten or more days per month can itself cause more frequent headaches — a pattern worth discussing with a qualified practitioner.
