When is it worth taking medication to prevent migraines, not just treat them?

Prevention is generally worth considering when migraines are frequent, long, or disabling enough to interfere with your life — for example, several migraine days a month, attacks that don't respond well to treatment, or headaches that are taking over your work and relationships. Preventive treatment aims to reduce how often and how severely attacks happen, rather than stopping one in progress. There's no single threshold that fits everyone, so whether it's worth it for you is a conversation to have with your GP based on how much migraine is costing you.

What are the options for preventing migraines?

There's a genuine menu. Several long-established tablet medicines (originally developed for other conditions, such as some blood pressure, antidepressant and anti-seizure medicines) are used to prevent migraine and are often tried first. There are also newer migraine-specific preventive treatments. Alongside medication, identifying and managing triggers, sleep, stress and the overuse of pain relief all matter. The right choice depends on your other health, what you've tried, and your preferences — which the decision aid below helps you sort into questions for your GP.

Can taking too much pain relief actually make migraines worse?

Yes — and it's commonly missed. Using acute pain relief or migraine medicines too often (a pattern called medication-overuse headache) can paradoxically lead to more frequent headaches over time. It's a real and reversible problem, but it usually needs a planned approach with your doctor rather than simply stopping suddenly. If you're reaching for pain relief on many days, that's important to mention to your GP, because addressing it can be a key part of getting on top of the headaches.

How long do preventive medicines take to work?

Preventive treatment usually needs time and a fair trial — often several weeks at an adequate dose before you can judge whether it's helping, and benefit is measured by fewer or less severe attacks rather than none at all. Many preventives are started low and increased gradually. Because it's a slower process, keeping a simple headache diary helps you and your GP see whether it's working. Adjusting or changing preventives is done with your doctor, not on your own.

Are there non-medication things that help prevent migraine?

Yes, and they sit alongside any medication rather than competing with it. Regular sleep, hydration, managing stress, consistent meals, and identifying your personal triggers can all reduce attacks for some people. Keeping a headache diary often reveals patterns you can act on. None of this replaces medical treatment when migraines are frequent or disabling, but it's a worthwhile part of the overall plan to discuss with your GP.

Migraine prevention — medication options

By Dr HB Lo, FACRRM Reviewed 14 June 2026 5 min read

General information to help you prepare for your GP — not a diagnosis, not personal medical advice. It doesn't replace a consultation, and using it doesn't create a doctor–patient relationship.

There are two different jobs in migraine treatment, and confusing them keeps people stuck. One is treating an attack when it hits; the other is preventing attacks from happening so often. This guide is about the second — preventive treatment — worth considering when migraines are frequent or disabling enough to reshape your life.

In Australia there's a real menu of preventive options, from long-established tablets to newer migraine-specific treatments, alongside identifying triggers and managing the overuse of pain relief, which can quietly make migraines worse.

This guide explains how the prevention decision is weighed, so you can take clear questions to your GP.

Treating an attack and preventing attacks are two different jobs

A lot of people stay stuck with migraine because the conversation only ever covers one half of it. There’s treating an attack once it has started — and there’s preventing attacks from happening so often in the first place. They use different medicines, aimed at different goals, and many people who are exhausted by frequent migraines have never been offered the second half at all.

This guide is about prevention. It explains when preventive treatment is worth considering and how the options are weighed, so you can take clear questions to your GP instead of simply riding out attack after attack. It’s general information, and it doesn’t tell you to start, stop or change any medicine.

When prevention is worth considering

There’s no single magic number, but prevention generally comes into the picture when migraines are frequent, long, or disabling enough to interfere with your life — when they’re costing you work days, relationships, or simply too much of your month, as HealthDirect and the Brain Foundation describe. The aim of preventive treatment is to reduce how often and how severely attacks strike, not to abolish every headache.

The honest framing is a trade-off: weighing how much migraine is taking from you against the commitment of a daily preventive. That’s a personal calculation, and it’s exactly what a good GP conversation is for.

There’s a genuine range, per Therapeutic Guidelines and Australian Prescriber:

Long-established tablet medicines — several were originally developed for other conditions (some blood pressure, antidepressant and anti-seizure medicines) and are used to prevent migraine. These are often tried first and are well understood.
Newer migraine-specific preventives — developed specifically for migraine, with their own eligibility criteria and access considerations.
Addressing the background — identifying triggers, and managing the overuse of acute pain relief, which can quietly worsen the whole picture.

Which option fits depends on your other health, what you’ve already tried, and your preferences — for instance, a medicine that helps a co-existing condition might do two jobs at once. The migraine prevention options decision aid below lays these out so you can weigh them and prepare your questions; it never picks one for you.

The trap worth knowing about: medication-overuse headache

This one is commonly missed and genuinely important. Using acute pain relief or migraine medicines on too many days can, over time, paradoxically increase how often headaches happen — a pattern called medication-overuse headache, as the Australian Medicines Handbook and Better Health Channel explain. It’s real and reversible, but it usually needs a planned approach with your doctor rather than stopping abruptly. If you’re reaching for pain relief on many days a month, that’s worth raising directly — sorting it out can be the key that unlocks the rest.

What to expect, and the non-medication side

Preventive treatment asks for patience. It often needs several weeks at an adequate dose before you can fairly judge it, and success is measured in fewer or milder attacks rather than none, per the RACGP. A simple headache diary is one of the most useful things you can bring — it helps you and your GP see whether a preventive is working and spot triggers. Alongside any medication, regular sleep, hydration, consistent meals and managing stress reduce attacks for some people. None of it replaces treatment when migraines are frequent, but it’s a real part of the plan.

When a headache isn’t a prevention question at all

Prevention is for recurring migraine — but some headaches need attention now, not a preventive plan. It’s worth knowing the warning signs that mean see a doctor promptly, or seek urgent care: a sudden, severe “worst-ever” headache that peaks in seconds, a headache with fever and a stiff neck, a new headache with weakness, numbness, confusion, vision loss or trouble speaking, a headache after a head injury, or a headache pattern that’s clearly new or rapidly changing — especially later in life, as HealthDirect and the Brain Foundation set out. These are not about prevention; they’re about ruling out something else.

The vast majority of recurring headaches are migraine or tension-type and are not dangerous — but knowing the red flags means you can act on the rare one that matters and stop quietly worrying about the common ones.

Migraine is more than the headache

It also helps to recognise that migraine is a neurological condition, not “just a bad headache” — it can come with nausea, sensitivity to light and sound, visual aura, and a wrung-out feeling for a day afterward, as the Better Health Channel describes. Naming the full picture to your GP — not only the pain — gives them more to work with, and helps make the case for prevention when attacks are genuinely disabling.

The questions worth taking in

Given how often and how badly I get migraines, is preventive treatment worth considering for me?
Which preventive options suit my situation and my other health?
Could medication-overuse be part of what’s keeping my headaches going?
How long should I give a preventive before we judge it, and how will we track whether it’s working?

These are questions, not conclusions. The aim is a plan made with your GP, fitted to you.

What this is, and is not

This is general information to help you prepare for your GP — not a diagnosis, and not personal medical advice. It doesn’t tell you to start, stop or change any medicine; those decisions are made with your own doctor, who can weigh your history.
