Most migraine attacks last between 4 and 72 hours, but the full “migraine cycle” (before and after the headache) can stretch the experience to several days. Very long attacks or sudden changes in your usual pattern should be checked by a doctor.

Typical migraine timeline

  • The main migraine headache usually lasts about 4–72 hours in adults.
  • Including all phases (warning signs, aura, headache, and “migraine hangover”), an attack can last from a bit over a day up to several days, and occasionally up to a week in total.
  • In children, migraine episodes are often shorter, sometimes as little as 1–2 hours in older children and 30 minutes in younger ones.

Phases of a migraine

  • Prodrome (warning phase) : Subtle symptoms like yawning, food cravings, mood changes, or neck stiffness can start 24–48 hours before the headache.
  • Aura : Some people get visual changes, tingling, or speech disturbance, usually lasting 5–60 minutes.
  • Headache phase : Throbbing or pulsing head pain, often with nausea and sensitivity to light/sound, typically 4–72 hours.
  • Postdrome (“migraine hangover”) : Tiredness, brain fog, and light sensitivity can linger 24–48 hours after the pain ends.

When it’s longer than 72 hours

  • A severe migraine that lasts more than 72 hours is sometimes called status migrainosus , and it is considered a complication that often needs urgent medical care.
  • People with chronic migraine can feel like they are in a near-continuous cycle, with frequent attacks and short gaps in between, even though each individual attack still follows the usual phases.

What affects how long it lasts?

  • Treating early with appropriate migraine medicines (like triptans, gepants, or certain NSAIDs) often shortens the attack and reduces how long symptoms linger.
  • Common prolonging factors include sleep disruption, dehydration, missed meals, hormonal changes, stress, and overuse of painkillers (which can cause medication-overuse headaches).

When to see a doctor urgently

  • First or “worst-ever” severe headache, especially if it peaks suddenly within seconds to a minute.
  • Migraine-like pain lasting longer than 72 hours, new neurological symptoms (weakness, trouble speaking, confusion), or headache after a head injury.
