Medication-Overuse Headache: Why Headache Medicine Plans Watch Pain Reliever Use Closely

There is a particular kind of tiredness in checking your bag for the blister pack before you have even left the house. Not because your head hurts yet, but because it might, and the meeting starts at nine. Over months, the pack becomes a habit, the headaches get quieter but more frequent, and the mornings start with a dull pressure that the first dose seems to lift. Nobody in that situation is doing anything reckless. They are doing exactly what the label suggests, just on more days than the label ever imagined.

That pattern is why headache specialists ask, sometimes to a patient’s surprise, not about the intensity of the pain but about the number of days a pain reliever was taken. The answer shapes the whole approach to medication overuse headache treatment, because the medicine that offers relief today can, taken too often, become part of why tomorrow hurts.

This explainer walks through how that happens, what supervised care usually involves, what the first weeks tend to look like, and which warning signs mean a headache needs urgent attention rather than another tablet.

What is medication-overuse headache?

Medication-overuse headache, once called rebound headache or analgesic headache, is a headache disorder that develops in people who already have a headache condition, most often migraine or tension-type headache, and who take acute pain relievers on a large number of days over several months. The word to hold onto is days. Clinicians count how many days a month a person used any acute headache medicine, not how many tablets they took on a bad day or how strong the medicine was.

The widely used diagnostic criteria describe headache on 15 or more days a month for more than three months in someone who has been regularly overusing one or more acute headache medicines. For simple pain relievers such as paracetamol (acetaminophen) or nonsteroidal anti-inflammatory drugs, regular use on 15 or more days a month meets the threshold; for triptans, opioids, ergotamines and combination products, the threshold is lower, at 10 or more days a month. These figures are quoted by the Mayo Clinic and Cleveland Clinic patient guidance and come from the International Classification of Headache Disorders.

Two features distinguish it from a simple bad stretch. The headache is present on more days than not, often on waking, and it tends to improve for a while after a dose only to return as the medicine wears off. The pain itself has no signature quality; it may feel like a dull daily ache with occasional migraine-like flares, or like the person’s usual migraine turned up in frequency.

The condition matters clinically because it sits behind a large share of near-daily headache seen in specialist clinics, and because it is reversible in many people once the pattern of use changes under supervision. That reversibility is precisely why headache medicine plans keep such a close eye on pain-reliever days from the first appointment.

How can a pain reliever start causing headaches?

The mechanism is not fully mapped, but the outline is consistent across research summaries from the Mayo Clinic and Johns Hopkins. Frequent exposure to acute headache medicine appears to change how the brain’s pain-processing systems respond, a process called central sensitization, which means the pathways that register head pain become more easily triggered and slower to settle.

Think of a smoke alarm recalibrated to go off at the smell of toast. Nothing is on fire, but the system has learned to fire early. In practical terms, the threshold for a headache drops, so ordinary triggers such as poor sleep, a skipped meal or a stressful afternoon produce pain that would previously have passed unnoticed.

A second strand involves the medicine wearing off. Triptans, a class of migraine medicines that act on serotonin receptors in blood vessels and nerves, and opioids, medicines derived from or mimicking morphine, are associated with a rebound effect: as the drug level falls, a headache returns, prompting another dose. Caffeine in combination products may add its own withdrawal headache. The person is not imagining the relief; each dose genuinely helps for a few hours. The problem is the loop it creates.

A third strand is that overuse seems to blunt the effect of preventive medicines. Clinicians repeatedly observe that daily preventive treatment works poorly while acute medicines are being taken on most days, and works better once use falls, which is why many treatment plans address both together.

None of this means pain relievers are dangerous when used on occasional days. The evidence points at frequency over time, not at the medicines themselves, and it points at people who already have a primary headache disorder. Someone without a headache condition who takes a pain reliever daily for arthritis does not typically develop medication-overuse headache.

Which pain relievers are most often involved in rebound headache?

Almost any acute headache medicine can be involved, but the risk and the threshold differ by class. The table below summarizes the day-count thresholds described in the diagnostic criteria and echoed in Mayo Clinic and Cleveland Clinic patient guidance. It is a description of how clinicians classify use, not a target or a permission slip; a headache plan may set a lower ceiling for an individual.

Medicine class (examples by generic name)	Monthly use threshold in diagnostic criteria	Notes clinicians commonly make
Simple analgesics (paracetamol/acetaminophen, ibuprofen, naproxen, aspirin)	15 or more days a month for over three months	Lower risk per day of use; often the first thing people reach for
Triptans (sumatriptan, rizatriptan and others)	10 or more days a month	Effective for migraine attacks; rebound pattern well described
Ergotamines	10 or more days a month	Older migraine medicines; less commonly prescribed now
Opioids (codeine, tramadol and others)	10 or more days a month	Associated with higher risk of overuse headache and physical dependence
Combination products (analgesic plus caffeine, with or without codeine)	10 or more days a month	Caffeine and codeine components add their own withdrawal effects
Any combination of the above	10 or more days a month in total	Days on different classes are added together

Two points deserve emphasis. First, the days add up across products. Someone who alternates an over-the-counter tablet with a prescription triptan may be well under either threshold individually and well over the combined one. Second, opioid and butalbital-containing products (butalbital is a barbiturate sedative sometimes combined with analgesics) carry additional concerns because abrupt withdrawal can be medically risky, which is one reason a supervised plan matters. Newer acute migraine medicines, such as gepants that block a pain-signaling protein called CGRP, are still being studied for overuse potential, and the evidence there remains limited.

How do headache medicine plans count pain reliever days?

The unglamorous tool at the heart of headache care is a diary. Whether it is a paper calendar, a phone app or a spreadsheet, it records three things for each day: whether a headache occurred, roughly how bad it was, and whether any acute medicine was taken. The NHS and the Mayo Clinic both recommend this kind of record because memory is unreliable in exactly the ways that matter here.

People tend to remember the dramatic attacks and forget the low-grade days when they took something “just in case.” Asked in clinic, many estimate five or six medicine days a month; the diary often shows twelve. That gap is not carelessness. Frequent headache blurs into the background of life, and so does the reflex to treat it.

Clinicians look for several patterns in the record. The first is the raw count of medicine days against the thresholds described earlier. The second is timing: headaches that cluster on waking, or that return predictably a few hours after a dose, suggest the rebound loop. The third is drift over time, a slow rise from a handful of days to most of the month, which often accompanies a headache disorder becoming chronic.

A diary also protects against the opposite error. Someone with frequent headaches who uses medicine on only a few days a month does not have medication-overuse headache, and labeling them with it would delay the right approach to their underlying condition. The record keeps the conversation anchored in what actually happened.

Many plans ask patients to keep the diary before, during and after any change in medicine use, because the same tool that identifies the problem also shows whether treatment is working. Improvement in medication-overuse headache is measured in fewer headache days and fewer medicine days, not in the disappearance of every headache.

What does medication overuse headache treatment actually involve?

Guideline-level care from sources such as the NHS and the Mayo Clinic rests on three linked elements, and the treating clinician decides how to combine them for a particular person.

The first is a supervised change in the overused medicine, sometimes called withdrawal or detoxification. In many cases the plan is to pause the medicine completely for a set period; in others, particularly with opioids or barbiturate-containing products, it is a gradual taper, meaning a stepwise reduction over days or weeks under medical guidance. Whether the pause happens at home with scheduled check-ins or in a hospital setting depends on which medicines are involved, other health conditions, and how the person has coped with previous attempts. This step is never something to improvise alone, because the right method depends on the specific medicine and the person’s history.

The second element is support through the transition. Clinicians sometimes use what they call bridge therapy, a short course of a different medicine, such as a brief steroid course or a long-acting anti-inflammatory, intended to soften the temporary worsening that follows withdrawal. The evidence for bridge therapy is mixed, and its use varies by clinician and by patient.

The third is preventive treatment, meaning a medicine or non-drug approach taken regularly to reduce how often headaches occur, so that the person is not pushed back toward frequent acute use. Some plans start prevention at the same time as withdrawal; others wait until use has fallen. Both approaches have supporters, and current evidence does not settle the question decisively.

Alongside all three sits education: understanding the day-count model, agreeing a personal monthly ceiling for acute medicine, and learning which non-drug tools can carry some of the load. The Mayo Clinic notes that many people improve after a supervised withdrawal, but the pace and extent vary, and the plan is adjusted as the diary reveals what is happening.

Who is usually offered supervised withdrawal, and who is asked to wait?

Withdrawal is generally offered to people who meet the diagnostic pattern and whose underlying headache disorder is reasonably clear. That includes most people with migraine or tension-type headache whose acute medicine days have crept above the thresholds for several months. For them, the conversation is usually about how and where to do it rather than whether.

Some situations prompt a more cautious or delayed approach. People taking opioids or butalbital-containing products on most days are typically offered a taper rather than an abrupt stop, and may be referred for more intensive support, because sudden withdrawal from these classes can cause more than a headache flare. Those with significant depression or anxiety, which the Mayo Clinic notes travel frequently alongside chronic headache, may need those conditions addressed in parallel so that a difficult few weeks does not tip into crisis.

Pregnancy changes the calculation as well. Many preventive and bridge medicines are avoided in pregnancy, so the plan leans harder on non-drug strategies and on close coordination with maternity care. Older adults, people with kidney or heart conditions, and those taking pain relievers for a separate painful illness such as arthritis or back pain also need individualized plans, since their acute medicine cannot simply be removed without addressing the other pain.

Someone whose headache has changed character recently, or who has red-flag features, is asked to wait for a different reason: the priority is ruling out another cause before anything is attributed to medication overuse. A diagnosis of medication-overuse headache assumes the underlying headache disorder is a known, primary one.

Finally, timing is a practical matter. Clinicians often suggest choosing a window without major deadlines, travel or caregiving pressures, because the first days after withdrawal are frequently worse before they are better. That is a scheduling decision made together, not a medical exclusion.

How long does medication-overuse headache last after stopping the medicine?

Honesty about the timeline is one of the most useful things a clinician can offer, because the first stretch is often the hardest. After the overused medicine is paused, most people experience a period of withdrawal headache, sometimes accompanied by nausea, restlessness, poor sleep or anxiety. The Mayo Clinic describes these symptoms as typically lasting from two to ten days, though they can persist for several weeks in some people, and notes that the duration tends to be longer when the medicine involved was a triptan, opioid or combination product rather than a simple analgesic.

Picture the pattern as a wave rather than a cliff. Days one to three frequently bring the peak, with headache on most or all days and a strong pull to take something. Toward the end of the first week, many people notice the pain becoming less constant. Over the following weeks, headache days usually decline, and the headaches that remain often start to look like the person’s original migraine or tension-type pattern rather than the daily background ache.

Clinicians commonly reassess around the two-month mark because the diagnostic criteria use improvement within about two months of stopping the overused medicine as supporting evidence that overuse was driving the headaches. If headache frequency has not changed by then, the team revisits the diagnosis and the plan.

What this timeline is not is a guarantee. Some people improve within days; others take longer, and a minority do not improve substantially, which usually signals that the underlying headache disorder needs more attention on its own terms. Sleep, hydration, regular meals and keeping the diary during these weeks are not decorative advice; they are the scaffolding that makes the wave survivable. Scheduled check-ins, by phone or in person, give the team a chance to adjust bridge or preventive treatment before frustration undoes the effort.

Why preventive medicine is part of medication overuse headache treatment

Removing the overused medicine addresses the loop, but it does not address why the person had frequent headaches in the first place. Without a preventive strategy, many people drift back toward the same frequency of acute use, which is why most guideline-based plans pair withdrawal with prevention.

Preventive medicines are taken regularly, whether or not a headache is present, with the aim of lowering how often attacks occur and how severe they are. Several classes are used for migraine prevention, and a clinician chooses among them based on the person’s other conditions, side-effect tolerance and preferences. Beta blockers, originally blood pressure medicines, appear to dampen the nervous system’s excitability. Certain antiseizure medicines stabilize overactive nerve signaling. Some antidepressants used at doses distinct from their mood indication alter pain processing in the brain. Botulinum toxin injections are used for chronic migraine and are thought to block the release of pain-signaling chemicals from nerve endings around the head and neck. Newer monoclonal antibodies target CGRP, a protein released during migraine attacks that widens blood vessels and transmits pain.

Mechanism matters here because it explains a common frustration: preventive medicines typically take weeks to show their effect. The Mayo Clinic and NHS both describe a trial period of several weeks to a few months before judging whether a preventive is working, and the diary is what makes that judgment possible.

Whether to start prevention before, during or after withdrawal is an open question in the research. Some studies suggest that starting a preventive without a formal withdrawal can reduce headache days on its own; others find withdrawal first improves the response. The evidence does not favor one sequence for everyone, and the decision rests with the prescribing clinician, who weighs the person’s specific medicines and circumstances. None of this involves the patient adjusting anything independently.

What helps besides medicine?

Non-drug approaches carry real weight in medication-overuse headache, partly because they work directly on headache frequency and partly because they give a person something to reach for other than a tablet during the difficult early weeks.

Sleep regularity is the least glamorous and among the most consistently supported. Both too little and too much sleep are recognized migraine triggers, and a fixed wake time seven days a week tends to steady the pattern. Regular meals matter for similar reasons; a dropping blood sugar mid-afternoon is a classic prompt for a headache, and for the medicine that follows it.

Caffeine deserves specific attention because it appears in many combination analgesics and in most people’s mornings. The Cleveland Clinic and Mayo Clinic both note that caffeine can contribute to rebound patterns, and that abruptly cutting a large daily intake produces its own withdrawal headache. A clinician may suggest reducing intake gradually alongside the medicine plan rather than doing both at once.

Physical activity has evidence for reducing migraine frequency, with moderate aerobic exercise several times a week the pattern most often studied. It also helps sleep and mood, both of which influence headache. Cognitive behavioral therapy, a structured talking therapy that works on the thoughts and habits around pain, has support in headache care and can specifically target the anticipatory pattern of taking medicine before a headache has actually arrived. Relaxation training and biofeedback, in which a person learns to influence physical signals such as muscle tension, have modest but real evidence.

Hydration, limiting alcohol and managing screen and posture habits are sensible but less strongly evidenced. What none of these do is replace the medical plan. They lower the baseline so that fewer headache days occur and the personal ceiling on acute medicine becomes easier to stay under.

Does medication-overuse headache come back?

It can, and headache medicine plans are built with that in mind. Research summarized by the Mayo Clinic and Johns Hopkins indicates that a meaningful proportion of people who improve after withdrawal return to frequent acute medicine use, with the highest risk in the first year. Exact figures vary widely between studies depending on the medicines involved, how relapse was defined and how long people were followed, so a single percentage would be misleading.

Several factors are associated with higher relapse risk in the research literature. Overuse of opioids or combination products is one. Having tension-type headache rather than migraine as the underlying disorder is another, possibly because the daily low-grade ache invites daily low-grade treatment. A long duration of overuse before treatment, and returning to the same overused medicine afterward, also appear to matter. Depression and anxiety that go unaddressed raise the risk as well.

Relapse is not a moral failing and clinicians do not treat it as one. The pattern that led to medication-overuse headache is a reasonable response to pain, and the pull back toward it is strong when a bad week arrives. What plans try to do is make the pull visible early. The monthly diary count is the smoke detector: when acute medicine days start climbing toward the personal ceiling, that is the moment to contact the team, not after three months back above threshold.

Follow-up appointments in the first year serve this purpose. So does having a written plan for what to do during a flare, including which non-drug tools to try first and when to call. Some people also benefit from an agreed rule, set with their clinician, about the maximum number of acute medicine days per week, which is easier to track in real time than a monthly total.

Improvement that lasts is the realistic goal, and it is achievable for many people, but it is maintained rather than finished.

What people often get wrong about painkiller headaches

Misunderstandings cluster around this condition, and several of them make it harder to treat.

The first is that it only happens with strong or prescription medicines. Over-the-counter simple analgesics can be involved when used on enough days, and because they feel harmless, their use is often the least noticed. The threshold is higher for them than for triptans or opioids, but it exists.

The second is that the pain is “not real” or is psychological because the medicine is causing it. The pain is entirely real, generated by a nervous system that has been sensitized. Calling it a habit problem misses the biology and tends to shame people who were following the instructions on the box.

The third is that the solution is simply to stop everything immediately. For some medicines and some people that is what a clinician will recommend; for others, especially those on opioids or barbiturate-containing products, an abrupt stop can be medically unsafe. The method has to match the medicine, which is why the decision belongs with the prescriber.

The fourth is that if the headache gets worse after stopping, the plan has failed. A worsening in the first days is the expected withdrawal phase described earlier, not evidence that the medicine was needed after all.

The fifth is that switching from one pain reliever to another resets the count. Days on different acute medicines are added together in the diagnostic criteria, so rotating products does not avoid the problem.

The sixth is that medication-overuse headache means a person can never use acute medicine again. Once frequency has fallen, most plans allow acute treatment on a limited number of days, tracked in the diary and agreed with the team. The aim is not abstinence but a sustainable ceiling.

A final misconception is that it will resolve on its own if ignored. Untreated, the pattern usually continues or worsens, and the underlying headache disorder becomes harder to treat with preventives.

Questions to ask your care team

A consultation about medication-overuse headache moves quickly, and it helps to arrive with questions written down. The following are ones that headache specialists commonly hear and are usually glad to answer, because they show the person understands the shape of the plan.

• Based on my diary, how many acute medicine days a month am I currently averaging, and which threshold does that fall against?
• Which of my medicines do you consider the overused one, and does the plan involve a complete pause or a gradual taper?
• Should the withdrawal happen at home with check-ins, or is there a reason you would recommend a more supervised setting for me?
• What should I expect in the first two weeks, and what specifically would make you want me to get in touch sooner than our next appointment?
• Are you suggesting a bridge medicine during withdrawal, and what is the evidence for it in my situation?
• Will a preventive medicine be part of the plan, when would it start, and how long before we judge whether it is working?
• What is my personal monthly ceiling for acute medicine once the pattern has settled, and how should I track it?
• Which non-drug approaches do you think would help most for my headache type?
• How do my other conditions, and any other regular medicines, affect the plan?
• What is our follow-up schedule over the next year, and who do I contact if my medicine days start climbing again?

Notice that most of these questions are about process and expectations rather than about which medicine is best. That reflects the reality of the condition: the specific preventive chosen matters less than having a clear, monitored plan and knowing when to raise a flag. Writing the answers down during the appointment, or asking for them in a written summary, saves a great deal of second-guessing during the weeks when concentration is at its worst.

When to call your doctor

Most headaches, including most medication-overuse headaches, are not dangerous. A small number signal something that needs urgent assessment, and the withdrawal period is not a time to assume every new symptom is expected. MedlinePlus and the NHS describe the following as warning features that warrant emergency care or an immediate call rather than waiting for a scheduled appointment.

Seek emergency help for a headache that reaches maximum intensity within seconds to a minute, often described as the worst headache of a person’s life; a headache accompanied by fever, stiff neck, rash or confusion; a headache with new weakness, numbness, difficulty speaking, loss of vision or double vision, or unsteadiness; a headache following a head injury, especially with drowsiness or vomiting; a headache with a seizure or fainting; or a headache during pregnancy or shortly after delivery that is new or severe.

Contact the care team promptly, though not necessarily as an emergency, if a headache pattern changes clearly in character, if a new type of headache begins after the age of fifty, if headache is consistently worse on lying down, coughing or straining, or if there is unexplained weight loss, night sweats or a history of cancer or a weakened immune system.

During a supervised withdrawal, a few additional situations should prompt a call: vomiting that prevents keeping fluids down, symptoms of severe anxiety or low mood, any thoughts of self-harm, or withdrawal symptoms that feel unmanageable rather than merely unpleasant. Clinicians expect these calls and would rather adjust the plan than have someone abandon it in distress.

The general principle is simple. Medication-overuse headache is diagnosed in someone whose headache disorder is already known. A headache that is new, different or accompanied by neurological symptoms is not part of that diagnosis until a clinician has said so.

How headache plans keep the pattern from returning

Once the acute phase has passed and headache days have fallen, the work of a headache medicine plan shifts from intervention to maintenance, and the emphasis returns to the same quiet tool it began with: the count of pain-reliever days.

Most plans settle on a personal ceiling agreed with the clinician, kept deliberately below the diagnostic thresholds to leave a margin for bad months. The diary continues, at least in a simplified form, because the drift back toward frequent use is gradual and easy to miss without a record. Some people find a weekly limit easier to hold in mind than a monthly one; others use an app that flags when the count is rising.

Preventive treatment, whether medicine, behavioral or both, is reviewed at intervals. If headache frequency has stayed low for an extended period, the clinician may discuss whether a preventive medicine can be reduced or paused; if frequency is creeping up, the preventive may be adjusted. These are clinical decisions made from the diary data, not from how a single week felt.

A written flare plan helps during the inevitable difficult stretches. It usually lists which non-drug measures to try first, the agreed acute medicine and its maximum number of days that week, and the point at which to contact the team. Having the plan on paper matters because judgment is poorest in the middle of a bad headache.

Life circumstances that push headache frequency up, such as a new job, a bereavement, hormonal changes or a period of poor sleep, are worth flagging to the team early rather than waiting for the diary to show the damage. Clinicians can often adjust the approach before overuse re-establishes.

What this amounts to is a different relationship with acute medicine: still available, still useful, but rationed by a number that the person and their clinician watch together. That shared vigilance, more than any single medicine, is what the evidence suggests keeps the door from swinging back open.

Frequently asked questions

What are the typical rebound headache symptoms clinicians look for?

Clinicians look for a pattern rather than a specific pain quality: headache on most days, often present on waking, that eases for a few hours after an acute medicine and returns as it wears off, in someone with a known headache disorder who uses acute medicine on many days a month. Restlessness, poor sleep and nausea sometimes accompany it. A headache diary showing the day count is far more informative than the character of the pain, and only a clinician can make the diagnosis.

What are the medication overuse headache diagnosis criteria?

The International Classification of Headache Disorders, as summarized by the Mayo Clinic and Cleveland Clinic, describes headache on 15 or more days a month for more than three months in someone with a pre-existing headache disorder who regularly overuses acute medicine: 15 or more days a month for simple analgesics, or 10 or more days for triptans, ergotamines, opioids, combination products, or any mix of classes. Improvement within about two months of stopping the medicine supports the diagnosis.

What does painkiller headache withdrawal feel like?

Most people experience a temporary worsening of headache in the first days after the overused medicine is paused, sometimes with nausea, anxiety, restlessness or disturbed sleep. The Mayo Clinic describes these symptoms as typically lasting two to ten days, occasionally several weeks, and longer on average after triptans, opioids or combination products. Clinicians expect this phase and may offer a short bridge treatment; it is not a sign that the medicine was needed after all.

Can I develop medication-overuse headache from over-the-counter painkillers alone?

Yes. Simple analgesics such as paracetamol (acetaminophen), ibuprofen or aspirin can be involved when used on 15 or more days a month for several months in someone with an underlying headache disorder. The threshold is higher than for triptans or opioids, but because these products feel harmless and are easy to buy, their frequent use is often the least noticed. A diary usually reveals the pattern more accurately than memory does.

Is medication overuse headache treatment done at home or in hospital?

Both settings are used, and the choice rests with the treating clinician. Many people withdraw from simple analgesics or triptans at home with scheduled check-ins. A more supervised setting is more often considered when opioids or barbiturate-containing products are involved, when previous attempts have failed, when there are significant mental health conditions, or when other illnesses complicate the picture. The decision depends on the medicine and the person, not on how bad the headaches feel.

Will I ever be able to take a pain reliever for a headache again?

In most plans, yes, within limits. Once headache frequency has fallen, clinicians typically agree a personal monthly ceiling on acute medicine days that sits below the diagnostic thresholds, and ask the person to track it in a diary. The goal is sustainable, occasional use rather than abstinence. What changes is the habit of taking medicine preemptively or on most days, and the awareness that the count, not the individual dose, is what matters.

Why is a preventive medicine suggested when the problem was too much medicine?

Because the overused medicine was treating frequent headaches that will still be there once it is removed. Preventive medicines are taken regularly to lower how often attacks occur, which reduces the pull back toward daily acute use. They act through different mechanisms, such as calming nervous system excitability or blocking pain-signaling proteins, and usually take several weeks to months to show effect. Whether to start before, during or after withdrawal is decided by the prescribing clinician.

Does caffeine make medication-overuse headache worse?

Caffeine can contribute. It appears in many combination analgesics and, according to the Cleveland Clinic and Mayo Clinic, can be part of a rebound pattern; cutting a large daily intake abruptly also causes its own withdrawal headache. Clinicians often suggest reducing caffeine gradually rather than at the same moment as the medicine pause, so that two withdrawal effects do not overlap. Moderate, consistent intake is less of a concern than large or irregular amounts.

How is medication-overuse headache different from chronic migraine?

They frequently coexist. Chronic migraine means headache on 15 or more days a month with migraine features on at least eight of them; medication-overuse headache describes the same frequency driven or maintained by acute medicine use. Many people meet both definitions. Clinicians often treat the overuse first because chronic migraine responds better to preventive treatment once acute medicine days have fallen, and then reassess which diagnosis best describes what remains.

What happens if I stop the medicine and my headaches do not improve?

Clinicians usually reassess around two months after withdrawal, because the diagnostic criteria use improvement within that window as supporting evidence. If headache frequency has not changed, the team revisits the diagnosis, considers whether another headache disorder or a secondary cause is present, and adjusts preventive treatment. Lack of improvement does not mean the effort was wasted; it provides useful information about what is driving the headaches and redirects the plan.
