A migraine attack typically lasts one to two days, though the headache itself can resolve in as few as four hours or stretch up to 72 hours without treatment. That range is wide because migraines aren’t just a headache. They unfold in phases, and the total experience, from the earliest warning signs to the lingering “hangover,” can span anywhere from just over a day to about a week in extreme cases.
The Four Phases of a Migraine Attack
What most people think of as “a migraine” is actually just the headache phase, one part of a larger event. Understanding all four phases helps explain why you might feel off for days around a single attack.
Prodrome is the early warning period. Hours or even a day or two before the pain starts, you might notice food cravings, unusual fatigue, mood shifts, neck stiffness, or frequent yawning. Not everyone recognizes these signals, but learning your pattern can give you a head start on treatment.
Aura affects roughly one in four people with migraines. It usually involves visual disturbances like shimmering lines, blind spots, or zigzag patterns, though it can also cause tingling, numbness, or difficulty finding words. Aura symptoms build gradually over about five minutes and typically resolve within an hour. In about 20% of people who experience aura, it can last longer than 60 minutes.
Headache is the main event: intense, often one-sided, throbbing pain that worsens with movement. Nausea, vomiting, and extreme sensitivity to light and sound are common companions. This phase lasts several hours to three days.
Postdrome, sometimes called the migraine hangover, lingers after the pain fades. It can last a few hours to two days and brings fatigue, difficulty concentrating, body aches, dizziness, and lingering light or sound sensitivity. Some people describe feeling “washed out” while others experience brief euphoria. Either way, you’re not fully back to normal yet.
How Treatment Changes the Timeline
Taking medication early in the headache phase can shorten an attack significantly. Triptans, the most commonly prescribed class of migraine-specific medication, provide meaningful pain relief within two hours for 42% to 76% of patients, depending on the specific drug. Over-the-counter anti-inflammatory painkillers relieve pain within two hours for roughly 46% to 52% of people, while combination medications (which pair a painkiller with caffeine or another ingredient) work for 62% to 80%.
Timing matters more than which pill you choose. The earlier you treat, the shorter the attack tends to be. Waiting until the pain is severe makes every option less effective. If you regularly find that your migraines outlast your medication, that’s worth discussing with your doctor, because switching drugs or adjusting your approach can make a real difference.
When a Migraine Won’t Stop
A migraine that lasts beyond 72 hours of continuous, debilitating pain is classified as status migrainosus. Brief breaks due to sleep or medication (up to 12 hours) don’t reset the clock. This is a medical complication that typically requires treatment in a clinical setting, because prolonged attacks raise the risk of dehydration from vomiting, medication overuse, and in rare cases, stroke.
If your headache has been unrelenting for three days or more, or if the pain is dramatically different from your usual migraines, seek medical attention rather than continuing to self-treat.
Migraines in Children Are Often Shorter
Kids and teenagers tend to have shorter migraine attacks than adults. Diagnostic guidelines set the minimum attack duration at two hours for children, compared to four hours for adults. In practice, many children experience attacks lasting well under two hours, sometimes only tens of minutes, while still showing all the other hallmarks of a migraine. These shorter attacks are just as real, and the pattern often shifts toward longer durations as children grow into adulthood.
What Affects How Long Your Migraines Last
No two people have the same migraine pattern, and even your own attacks can vary in length from one episode to the next. Several factors influence duration:
- How quickly you treat it. Medication taken at the first sign of pain shortens attacks more reliably than medication taken once pain is fully established.
- Sleep. Getting restful sleep during an attack often helps resolve it. Many people find that a migraine is gone after a nap, while disrupted or inadequate sleep tends to drag it out.
- Hydration and food. Dehydration and skipped meals can both trigger and prolong attacks. Staying hydrated and eating something bland, even when nauseous, supports faster recovery.
- Stimulus control. Reducing exposure to light, sound, and strong smells during an attack helps your nervous system settle more quickly.
- Attack frequency. People who experience 15 or more headache days per month for three months or longer meet the criteria for chronic migraine. At that frequency, attacks can feel like they blur together, and preventive treatment becomes more important than treating each episode individually.
The postdrome phase is often overlooked when people ask how long a migraine lasts. Even after the pain is gone, the fatigue, brain fog, and sensitivity can linger for another day or two. Planning for lighter activity during this window, rather than jumping straight back into a full schedule, helps avoid triggering a rebound attack.
