A migraine headache typically lasts between 4 and 72 hours without treatment. But the headache itself is only one part of the story. A full migraine attack, including the warning signs before and the recovery period after, most commonly spans one to two days. In rare cases, the entire experience can stretch to just over a week.
The Headache Phase
The throbbing, often one-sided head pain that most people think of as “the migraine” falls within a wide range. Some people get through it in four or five hours. Others endure it for a full three days. Where you land in that window depends on factors like how quickly you treat it, how well you slept, your stress levels, and your individual biology. Many people find their attacks settle into a somewhat predictable pattern over time, with each episode lasting roughly the same number of hours.
If you take a fast-acting medication early in an attack, you can significantly shorten this window. Tablet forms of common migraine-specific medications begin working in 30 to 60 minutes. Injectable versions can kick in within 10 to 15 minutes, and nasal sprays typically work within 15 minutes. The key is timing: treating early, before the pain fully escalates, tends to produce the best results.
The Full Attack Is Longer Than the Headache
A migraine attack has up to four distinct phases, and the headache is just one of them. Not everyone experiences every phase with every attack, but understanding the full timeline helps explain why you might feel “off” for days even though the worst pain only lasted several hours.
Prodrome (Hours to Days Before)
Many people notice subtle changes a day or two before the headache hits. You might feel unusually tired, irritable, or crave specific foods. Some people experience neck stiffness, frequent yawning, or difficulty concentrating. These warning signs are easy to miss if you’re not looking for them, but they’re part of the migraine process, not a separate issue. Learning to recognize your prodrome can give you a valuable head start on treatment.
Aura (5 to 60 Minutes)
About one in four people with migraine experience aura, a set of neurological symptoms that usually appear shortly before or at the start of the headache. Visual aura is the most common type: you might see zigzag lines, flashing lights, or blind spots that slowly expand across your field of vision. Some people get tingling in their face or hands, or have trouble finding words.
Aura symptoms typically build over at least five minutes and resolve within an hour. In roughly 20% of people who get aura, it can last longer than 60 minutes. Continuous aura lasting more than a week is possible but uncommon.
Postdrome (Hours to Two Days After)
Once the headache fades, many people enter what’s often called a “migraine hangover.” The pain is gone, but you feel drained, foggy, and not quite yourself. Common postdrome symptoms include fatigue, body aches (especially a stiff neck), difficulty concentrating, lingering light and sound sensitivity, dizziness, nausea, and mood changes ranging from mild depression to, surprisingly, euphoria.
This recovery phase starts right after the head pain ends and can last anywhere from a few hours to about 48 hours. It’s a real, physiological part of the attack, not just being tired from the pain. Pushing yourself too hard during postdrome can sometimes retrigger the headache.
When a Migraine Won’t Stop
A migraine that lasts longer than 72 hours is classified as status migrainosus. This is considered a complication of migraine, not just a long attack. The International Headache Society defines it as a debilitating migraine that continues uninterrupted for more than three days. Brief breaks in pain lasting up to 12 hours from medication or sleep don’t reset the clock.
Status migrainosus often requires medical intervention beyond your usual treatment plan. If your migraine has persisted past the 72-hour mark and your normal medications aren’t breaking the cycle, it’s worth seeking urgent care. Prolonged attacks raise the risk of dehydration (from nausea and reduced fluid intake) and can be deeply disruptive to daily life.
Episodic vs. Chronic Migraine
How long individual attacks last is different from how often they occur, and that distinction matters. Most people with migraine have the episodic form, meaning attacks come and go with stretches of normal days in between.
Chronic migraine is diagnosed when you have headaches on 15 or more days per month for more than three months, with at least 8 of those days meeting the criteria for migraine. At that frequency, it can feel like you’re never fully between attacks. The line between episodic and chronic migraine isn’t fixed. People can shift from one category to the other over time, and treatment plays a major role in which direction things move.
Migraines in Children Are Often Shorter
Children and adolescents tend to have shorter migraine attacks than adults. While the adult threshold starts at four hours, pediatric migraines can resolve in as little as one hour. The pain is also more likely to affect both sides of the head rather than just one, which can make it harder for parents to distinguish from a tension headache. Despite the shorter duration, the intensity can be just as severe, and children may have more prominent nausea and vomiting relative to head pain.
What Affects How Long Your Migraines Last
Several factors influence whether your attacks tend toward the shorter or longer end of the spectrum:
- Treatment timing. Taking medication at the first sign of an attack, especially during prodrome or early headache, consistently produces shorter episodes than waiting until pain is severe.
- Sleep. Both too little and too much sleep can extend an attack. Many people find that sleeping through the worst of the pain shortens the overall episode.
- Trigger exposure. Continued exposure to whatever set off the attack (bright lights, strong scents, stress) can prolong it. Removing yourself from triggers when possible helps the attack resolve faster.
- Medication overuse. Using pain relievers too frequently (generally more than 10 to 15 days per month, depending on the type) can paradoxically make attacks last longer and occur more often.
- Hydration and food. Dehydration and skipped meals are common migraine triggers and can also extend an existing attack. Even when nausea makes eating difficult, small sips of water and light snacks can help.
If your attacks are consistently lasting longer than they used to, or if they’re becoming more frequent, that pattern itself is useful information for your doctor. Tracking the duration of each attack, including the prodrome and postdrome periods, gives a clearer picture than just counting headache days.
