A typical migraine headache lasts between 4 and 72 hours when untreated, according to the International Headache Society’s diagnostic criteria. But the full experience of a migraine attack, including the buildup and recovery, can stretch well beyond that window. How long yours lasts depends on whether you treat it early, which phase you’re counting, and whether you experience migraines occasionally or frequently.
The Four Phases and How Long Each Lasts
A migraine attack isn’t just a headache. It unfolds in up to four distinct phases, and most people don’t experience all of them every time. Understanding these stages helps explain why a migraine can feel like it dominates an entire day or even several days.
The prodrome is the early warning phase. You might notice food cravings, mood shifts, neck stiffness, frequent yawning, or unusual fatigue. This phase can last several hours or stretch over one to two days before the headache begins. Not everyone recognizes it in the moment, but tracking patterns over time makes it easier to spot.
The aura phase affects roughly one in four people with migraines. It typically involves visual disturbances like flickering lights, zigzag lines, or blind spots, though it can also cause tingling, numbness, or difficulty speaking. Aura symptoms build gradually over at least five minutes and usually resolve within 60 minutes, though about 20% of people experience auras lasting longer than an hour.
The headache phase is what most people think of as “the migraine.” It typically lasts several hours to three days, with throbbing or pulsing pain that worsens with physical activity. Nausea, vomiting, and extreme sensitivity to light and sound are common during this window.
The postdrome, sometimes called a migraine hangover, follows the headache. It can last a few hours to two days. During this time you may feel exhausted, foggy, sore (especially in the neck), dizzy, or emotionally off. Some people describe brief euphoria, while others feel mildly depressed. Light and sound sensitivity can linger into this phase as well.
Adding it all up, a single migraine attack from first prodrome symptoms through full postdrome recovery can span anywhere from about half a day to nearly a week in severe cases.
When a Migraine Won’t Stop
A migraine that persists beyond 72 hours is classified as status migrainosus. This is considered a complication of migraine, not just a long attack. The pain is unremitting and debilitating, and it requires medical attention. Brief interruptions of up to 12 hours from sleep or medication don’t reset the clock. If your migraine has lasted more than three full days with severe, continuous symptoms, that crosses the threshold from a typical attack into something that needs professional intervention.
Migraines in Children Are Often Shorter
Children and adolescents tend to have shorter migraine attacks than adults. While the standard adult threshold starts at four hours, attacks in children can be as short as two hours. Kids are also more likely to experience pain on both sides of the head rather than the classic one-sided pattern, and nausea or vomiting tends to be more prominent. The shorter duration can make pediatric migraines harder to recognize, especially when they resolve before a parent or teacher connects the symptoms.
How Treatment Changes Duration
Early treatment is the single biggest factor in cutting a migraine short. Prescription medications designed specifically for migraines (the class known as triptans) work best when taken at the first sign of headache pain rather than after it’s fully established. A large meta-analysis found that standard doses provided meaningful headache relief within two hours for 42% to 76% of patients and complete pain freedom within two hours for 18% to 50%. Those are dramatically better odds than waiting it out.
The timing matters more than the specific medication. Treating early, during the prodrome or the very start of head pain, can sometimes stop the attack from progressing to its full duration. Waiting until the pain is severe makes any treatment less effective and increases the chance the migraine will run closer to its full 72-hour potential. Over-the-counter pain relievers can also help for mild to moderate attacks, but the same principle applies: earlier is better.
Episodic vs. Chronic Migraine
The duration of individual attacks is separate from how often they occur, but frequency changes the overall experience significantly. Episodic migraine means you have fewer than 15 headache days per month. Most people with migraine fall into this category, experiencing attacks anywhere from once a year to several times a month.
Chronic migraine is defined as headache on 15 or more days per month for more than three months, with at least 8 of those days having migraine features. At this frequency, individual attacks can blur together, making it difficult to tell where one ends and the next begins. People with chronic migraine often describe feeling like they’re always in some phase of an attack, cycling between prodrome, headache, and postdrome with little break in between. The individual attack duration may still follow the 4-to-72-hour pattern, but the lived experience feels nearly continuous.
What Affects Your Personal Duration
Several factors influence how long your migraines tend to last. Sleep quality plays a major role: poor sleep or disrupted sleep patterns can extend attacks and make them harder to treat. Hormonal fluctuations, particularly around menstruation, tend to produce longer and more treatment-resistant migraines. Dehydration, skipped meals, and high stress levels can all prolong an attack once it starts.
Your personal pattern also tends to be somewhat consistent. If your migraines typically last 8 to 12 hours, that’s likely your baseline. An attack that suddenly lasts much longer than your norm, especially past 72 hours, is worth noting and discussing with a healthcare provider. Similarly, if your attacks are becoming more frequent over time, gradually creeping from a few per month toward that 15-day chronic threshold, that shift is important to track. A headache diary noting start time, end time, and what you did to treat each attack is one of the most useful tools for understanding your own pattern and communicating it clearly.
