Migraine Management in Australia: Triggers, Prevention, and Treatment
Migraine is not just a bad headache. It is a neurological condition involving recurrent attacks of head pain, often with a cluster of other symptoms, that can disrupt work, sleep, and daily life. Around 4.9 million Australians live with migraine, and roughly 7 per cent experience chronic migraine, defined as 15 or more headache days per month (Migraine Australia, 2026). It is one of the leading causes of disability among Australian adults under 50, and women are affected roughly three times as often as men.
A migraine attack typically has four phases, though not everyone experiences all of them.
- Prodrome, hours to a day before the headache, with subtle changes such as mood shifts, food cravings, neck stiffness, yawning, or fatigue.
- Aura, in around a third of patients, lasting 5 to 60 minutes. Usually visual (zigzag lines, blind spots, flashes), sometimes sensory (tingling), occasionally affecting speech.
- Headache, often one-sided, throbbing, moderate to severe, worse with movement, lasting 4 to 72 hours when untreated. Frequently with nausea, vomiting, light sensitivity, sound sensitivity, or smell sensitivity.
- Postdrome, the day after, with fatigue, low mood, and difficulty concentrating.
The plain-English version is this: migraine is a brain condition with a pain phase, not a pain condition that lives in the skull. That distinction matters for treatment, because the right approach is rarely "stronger painkillers" and is often a combination of an acute medication for attacks, a preventer for frequent attacks, trigger management, and lifestyle adjustments.
This guide walks through the common triggers, how a GP distinguishes acute from preventer treatment, what the major drug categories look like at the class level, and when migraine should be escalated beyond general practice.

No two patients have exactly the same trigger list, and triggers are usually cumulative rather than singular. The common contributors a GP will ask about include:
Sleep. Both too little and too much. Irregular sleep is one of the most reliable triggers, and shift work is a known difficulty.
Stress, and the let-down after stress. Many patients notice attacks the weekend after a hard week, not during the week itself.
Hormones. Around menstruation, in perimenopause, and with some hormonal contraception. A GP can talk through whether contraception choice or hormone timing might be contributing.
Skipping meals and dehydration. Low blood glucose and low fluid intake are common, and easily fixable, contributors.
Alcohol. Particularly red wine for some patients, but any alcohol can trigger attacks in others.
Caffeine. Both excess intake and abrupt withdrawal can trigger migraine. Patients on three or four coffees a day who taper too quickly often pay for it.
Specific foods. Aged cheeses, cured meats, chocolate, and monosodium glutamate are commonly cited. The evidence is mixed, and food triggers are genuinely individual rather than universal.
Bright or flickering light, strong smells, and loud noise. Some patients are clearly sensitive even between attacks.
Weather changes. Particularly drops in barometric pressure.
Medication overuse. Taking acute pain medication on more than 10 to 15 days per month, depending on the class, can flip episodic migraine into chronic daily headache. This is one of the most under-recognised drivers of "migraine that just keeps getting worse" and is fixable, though uncomfortable to fix.
A headache diary, tracking attacks, severity, suspected triggers, sleep, menstrual cycle, and medication use, is one of the most useful tools in migraine care. A GP will often ask you to keep one for 4 to 8 weeks before deciding on preventer treatment.
Most migraine is diagnosed on history alone. There is no single test, and brain imaging is not routinely needed. A GP will ask about the pattern of attacks, the symptoms during them, the triggers, the family history (migraine runs in families), and how they affect your life.
There are clear features that change the picture and prompt further investigation. A GP will look out for:
- Sudden, severe headache ("thunderclap"), particularly the worst headache of your life.
- New headache after age 50.
- Headache with fever, neck stiffness, rash, or confusion.
- Headache after head injury.
- Headache with new neurological symptoms such as weakness, persistent visual loss, difficulty speaking, or seizures.
- Headache in the context of cancer, immunosuppression, or pregnancy.
- Progressive headache that is steadily worsening over weeks.
These features warrant urgent in-person assessment, sometimes via an emergency department, not a routine appointment. Most migraine is none of the above, but the categories matter and a GP is trained to recognise them.
Migraine treatment splits into two halves, and many patients arrive on the wrong half.
Acute treatment is what you take during an attack. It aims to stop or shorten the current episode. The right time to take acute medication is early in the attack, not late.
Preventer (prophylactic) treatment is what you take every day to reduce how often attacks happen, how severe they are, and how long they last. It is considered when:
- Attacks happen more than 4 days per month, or
- Attacks are severe and disrupt work or life despite acute treatment, or
- Acute medication is being taken too often (medication overuse risk), or
- Specific patterns (menstrual migraine, hemiplegic migraine, prolonged aura) warrant it.
Many patients with frequent attacks have only ever been offered acute treatment. Adding a preventer often changes the trajectory of the condition.
A GP will help you work out which half you need, or whether you need both. The combination of an effective preventer plus a well-timed acute treatment is usually more impactful than escalating doses of acute medication alone.
The drug categories most commonly used in Australian general practice for migraine, at the class level only, are:
For acute attacks:
- Simple analgesics class. First-line for many patients with mild to moderate attacks. Best taken early, with adequate dose, and not on more than 15 days per month to avoid medication-overuse headache.
- Anti-nausea medication class. Reduces nausea and vomiting, and improves absorption of other medications taken at the same time. Many patients underuse this.
- Triptan class. Migraine-specific medications for moderate to severe attacks not relieved by simple analgesics. Best taken early. Several routes of administration are available. Use is capped at no more than 10 days per month to avoid medication-overuse headache.
- Combined approaches. A simple analgesic plus an anti-nausea medication, or a triptan plus an anti-nausea medication, often works better than any single agent.
For prevention (preventers):
- Beta-blocker class. A long-established preventer for migraine, particularly useful in patients who also have high blood pressure or anxiety symptoms. Not suitable in some cases of asthma.
- Anti-epileptic class. Several medications in this category have evidence for migraine prevention. Choice depends on side-effect profile and other conditions.
- Tricyclic class. Useful particularly when migraine coexists with sleep disturbance or chronic tension-type headache. Often given at low doses at night.
- CGRP-targeted class. A newer category of migraine-specific preventers, including monthly or quarterly injections and oral options, generally accessed via specialist input and with specific eligibility criteria in Australia.
- Other classes are also used in selected patients.
A GP will choose a preventer based on your attack pattern, other conditions, pregnancy plans, side-effect tolerance, and cost. Preventers usually need 6 to 12 weeks at an effective dose before you can judge whether they are working, which patients often aren't told and which is the most common reason a "preventer didn't work" was never given a fair trial.
We don't name molecules or brands here. The right combination is a clinical decision made with you and your GP, not a default chosen from a blog.
If you are stable on your acute or preventer regimen, an online prescription review with a GP can save a trip. New diagnoses and changes are best discussed in a full consult. Pathology is occasionally requested before starting some preventers and can be processed at a regular collection centre.
Online appointments for migraine care
Most migraine is managed in general practice. There are clear situations where a GP will refer to a neurologist or headache specialist.
- Frequent or chronic migraine (15 or more headache days a month) that hasn't responded to two or more preventer trials at an adequate dose for an adequate duration.
- Suspected medication-overuse headache, where a structured detoxification plan is needed.
- Severe or atypical features such as hemiplegic migraine, prolonged aura, or stroke-like symptoms.
- Migraine in pregnancy or breastfeeding where treatment options need to be carefully weighed.
- Failure to tolerate or respond to standard preventers, particularly where access to CGRP-targeted treatment under specialist criteria might be appropriate.
- Diagnostic uncertainty, particularly where features could indicate a different headache disorder.
Migraine is also commonly associated with depression, anxiety, sleep disorders, and other chronic conditions. A coordinated care approach often helps. If you live with another chronic condition, our guides on type 2 diabetes management, high blood pressure management, and asthma action plans walk through how those plans interact with migraine care.
Abby Health is an online-first clinic where Australian GPs see chronic and family health patients seven days a week. Migraine is one of the most common conditions our clinicians manage, and the format suits ongoing care well.
The continuity matters. The next time you see an Abby GP, your headache diary, current acute and preventer regimen, recent pathology, and previous plan are in front of them. You don't repeat the story from scratch. Abby AI, our medical AI, surfaces history before the consult and supports the doctor; it never replaces clinical judgment.
You can schedule an appointment for a new diagnosis, a preventer review, an acute medication conversation, or a care plan update. If your pattern changes, or if you suspect medication overuse, that is a worthwhile reason to book.
Abby Health is bulk billed for eligible patients with a valid Medicare card. Strict eligibility criteria apply.
