How to Get Rid of a Headache: Types, Causes & OTC Relief

How to Get Rid of a Headache Fast

To help relieve a headache, rest in a quiet, dark room and drink water — dehydration is a common trigger. A cold compress on the forehead or a warm compress on the neck can ease tension. For most tension headaches, paracetamol (e.g. Panadol) or ibuprofen (e.g. Nurofen) may help relieve symptoms — ask your pharmacist which suits you. Migraines often also need rest and sleep in a dark, quiet space. Seek urgent medical care if a headache is sudden and severe, or comes with fever, a stiff neck, vision changes, confusion, or weakness.

Why the Type of Headache Matters

Headaches are one of the most common health complaints in Australia, affecting around 87% of Australians at some point. But 'headache' is not a single condition — it is an umbrella term covering many different types, each with different causes, symptoms, and treatments. Taking the wrong approach can mean the treatment does not work, or in some cases, makes things worse. This guide covers the five most common headache types and the best way to treat each one using products available over the counter in Australian pharmacies.

1. Tension Headaches

Tension-type headaches are the most common headache, accounting for roughly 70% of all headaches. They feel like a dull, constant pressure or tightness on both sides of the head — often described as a band squeezing around the forehead. The pain is mild to moderate and does not usually stop you from carrying on with daily activities.

Tension headaches can feel similar to a mild migraine, so if you are unsure which one you have, see our full migraine vs tension headache comparison guide for a detailed breakdown of how to tell them apart.

Best OTC treatments for tension headaches

Simple analgesics are the first-line treatment. Paracetamol (500mg to 1000mg) is the gentlest option and works well for most tension headaches. Ibuprofen (200mg to 400mg) is an alternative, particularly if there is any muscle or neck tenderness contributing to the pain. Take at the first sign of the headache — do not wait for it to become severe.

2. Migraines

Migraines are much more than a bad headache. They are a neurological condition causing moderate to severe throbbing pain, usually on one side of the head. Migraines often come with nausea, vomiting, and extreme sensitivity to light and sound. Some people experience an 'aura' before the pain starts — visual disturbances such as flashing lights, zigzag lines, or temporary blind spots. Migraines affect around 12% of Australians and are more common in women.

Migraines are often confused with severe tension headaches or sinus headaches. For a detailed, side-by-side breakdown of the symptoms that tell them apart, see our full migraine vs tension headache comparison guide.

Best OTC treatments for migraines

Timing is critical with migraines. Take your OTC pain reliever as early as possible — ideally at the first sign of symptoms or during the aura phase. Delaying treatment significantly reduces effectiveness because migraine slows down stomach emptying, meaning tablets are absorbed more slowly as the attack progresses.

Ibuprofen (400mg) is one of the most effective OTC options for migraines and is supported by good clinical evidence. Soluble aspirin (900mg) is another evidence-based choice — the soluble form is preferred because it is absorbed faster than standard tablets. Paracetamol combined with caffeine (such as Panadol Extra) can also be effective; the caffeine improves absorption and has a mild pain-relieving effect of its own.

3. Sinus Headaches

True sinus headaches come from inflammation or infection of the sinuses (sinusitis), producing a deep, constant ache in the cheekbones, forehead, or bridge of the nose that usually worsens on bending forward, alongside a genuinely blocked nose and thick, discoloured mucus. Important note: research suggests around 90% of self-diagnosed 'sinus headaches' are actually migraines — if yours comes with nausea, light sensitivity, or throbbing pain and your nose is not truly congested, treat it as a migraine instead. For the full comparison, the OTC treatment ladder (saline, steam, decongestants, pain relief), and when antibiotics are actually needed, see our dedicated guide: Sinus Headache Treatment and How to Tell It From a Migraine.

4. Cluster Headaches

Cluster headaches are rare but extremely painful — often described as one of the most severe pain conditions known. They produce intense, burning or piercing pain behind or around one eye. Unlike migraines, cluster headaches tend to be short (15 minutes to 3 hours) but can occur multiple times a day, often at the same time each day, in 'clusters' lasting weeks or months. They are more common in men.

How to identify a cluster headache

• radio_button_uncheckedSevere, sharp, or burning pain behind or around one eye
• radio_button_uncheckedPain is always on the same side during a cluster period
• radio_button_uncheckedEye on the affected side may water, become red, or have a drooping eyelid
• radio_button_uncheckedNostril on the affected side may become blocked or runny
• radio_button_uncheckedRestlessness — people with cluster headaches often pace or rock during an attack (unlike migraine sufferers who prefer to lie still)
• radio_button_uncheckedAttacks last 15 minutes to 3 hours, often occurring at the same time daily

Treatment for cluster headaches

Standard OTC painkillers are generally not effective for cluster headaches because the attacks are too severe and peak too quickly for oral medicines to take effect in time. If you suspect you are having cluster headaches, see your GP as soon as possible. Effective treatments exist — including high-flow oxygen therapy and fast-acting triptans — but these require a prescription or specialist referral.

5. Medication-Overuse Headaches

This is a common but often overlooked problem. If you take headache medicines regularly — 15 or more days a month for simple painkillers, or 10 or more for codeine, triptans and caffeine combinations — the medicines themselves can start causing headaches, sometimes called 'rebound headache'. The only effective treatment is to reduce or stop the overused medicine, best done with your GP's guidance, and it is fully reversible. For the day thresholds by medicine type, what withdrawal involves, and how to prevent it, see our dedicated guide: Medication-Overuse Headache: Causes and How to Break the Cycle.

Paracetamol vs Ibuprofen for Headaches: Which Should You Choose?

This is one of the most common questions Australians have about headache treatment. Both are effective, safe, and widely available — but they work differently and suit different situations.

Bottom line: for a standard tension headache, either will work well — choose paracetamol if you want the gentlest option, or ibuprofen if you want faster relief or there is any inflammatory component (such as neck stiffness). For migraines, ibuprofen has stronger evidence of effectiveness. If one alone is not giving enough relief, some adults can take both short term, but ask a pharmacist first. Follow each product's own dose and dosing interval, and don't add either one to a combination tablet that already contains paracetamol and ibuprofen.

How to Prevent Headaches

Prevention is always better than treatment. While you cannot avoid every headache, these evidence-based strategies can significantly reduce how often they occur:

• radio_button_uncheckedStay hydrated — dehydration is one of the most common and easily avoided headache triggers. Aim for at least 2 litres of water a day, more in hot weather
• radio_button_uncheckedMaintain a regular sleep schedule — both too little and too much sleep can trigger headaches. Aim for 7 to 9 hours per night and try to go to bed and wake up at consistent times
• radio_button_uncheckedManage stress — regular exercise, deep breathing, yoga, or meditation can reduce stress-related headaches
• radio_button_uncheckedTake regular screen breaks — follow the 20-20-20 rule: every 20 minutes, look at something 20 feet (6 metres) away for 20 seconds
• radio_button_uncheckedWatch your posture — poor posture, particularly when working at a desk or looking down at a phone, puts strain on neck and shoulder muscles
• radio_button_uncheckedLimit alcohol and caffeine — both can trigger headaches. If you regularly drink caffeine, avoid sudden withdrawal as this is a common headache cause
• radio_button_uncheckedKeep a headache diary — tracking when headaches occur, what you ate, how you slept, and your stress levels can help identify your personal triggers
• radio_button_uncheckedDo not skip meals — low blood sugar can trigger headaches, particularly migraines

Red Flags: When a Headache Needs Urgent Medical Attention

Most headaches are not dangerous. However, in rare cases a headache can be a sign of a serious medical condition. Call 000 or go to your nearest emergency department immediately if you experience any of the following:

You should also make a non-urgent appointment with your GP if your headaches are becoming more frequent, are not responding to OTC treatments, or are affecting your work or quality of life.

Frequently Asked Questions

What gets rid of a headache fast?

For a typical tension headache, the fastest combination is usually rest in a quiet, dark room, a glass or two of water, and a simple pain reliever such as paracetamol (e.g. Panadol) or ibuprofen (e.g. Nurofen) taken at the first sign of pain. A cold compress on the forehead or a warm compress on the neck can ease the pressure within minutes. Faster-absorbing forms — such as soluble or liquid-capsule products — may help relieve symptoms a little sooner than standard tablets. Always read the label and ask your pharmacist which option suits you.

What are common causes of headaches?

The most common everyday triggers are dehydration, stress and muscle tension, poor or irregular sleep, skipped meals and low blood sugar, eye strain from screens, poor posture, and caffeine or alcohol. Hormonal changes, weather shifts, and certain foods can also trigger migraines in susceptible people. Keeping a simple headache diary — noting what you ate, how you slept, and your stress levels — is one of the best ways to identify your personal triggers so you can avoid them.

Can dehydration cause a headache?

Yes — dehydration is one of the most common and easily avoided headache triggers. When you do not drink enough fluid, the body loses water and electrolytes, which can trigger a dull, all-over headache that often worsens when you move your head. It is more likely in hot Australian weather, after exercise, or after drinking alcohol. Rehydrating with water and resting often helps relieve a dehydration headache within a few hours. Aim for around 2 litres of fluid a day, and more when it is hot or you have been active.

How do I know what type of headache I have?

Look at where the pain is, what it feels like, and what comes with it. A tension headache feels like a dull, pressing band across both sides of the head, with no nausea. A migraine is usually a throbbing, one-sided pain with nausea and sensitivity to light or sound. A sinus headache causes deep pressure in the cheeks, forehead, or nose bridge alongside a blocked nose. A cluster headache is severe, burning pain behind one eye with a watering or red eye. Use the 'Headache Types at a Glance' table above to compare your symptoms side by side — and see your pharmacist or GP if you are unsure.

What is a medication-overuse (rebound) headache?

A medication-overuse headache (also called a rebound headache) is a headache caused by taking pain-relief medicines too often. If you use simple painkillers like paracetamol or ibuprofen on 15 or more days a month — or combination or stronger products on 10 or more days a month — for three months or longer, the medicines themselves can start triggering headaches. The pain often returns as each dose wears off, prompting another dose and creating a cycle. The only effective treatment is to stop the overused medicine, which is best done with guidance from your GP.

Can I take paracetamol and ibuprofen together for a headache?

Yes, some adults can take both short term, but ask a pharmacist first, and don't do it regularly without speaking to your pharmacist or GP. Follow each product's own dose and dosing interval — taking both does not mean you can exceed the maximum dose of either. Don't add either one to a combination tablet that already contains paracetamol and ibuprofen.

How often can I take painkillers for headaches?

For occasional headaches, take paracetamol or ibuprofen as directed on the pack (paracetamol every 4 to 6 hours, up to 4g daily; ibuprofen every 6 to 8 hours, up to 1200mg daily for OTC use). The key rule is to avoid regular use on more than 15 days per month for simple analgesics or more than 10 days per month for combination products, as this can lead to medication-overuse headaches.

Is it safe to take aspirin for a headache?

Aspirin is an effective headache treatment, particularly for migraines. Soluble aspirin (such as Aspro Clear) is absorbed quickly and has good evidence for migraine relief at a dose of 900mg. However, aspirin is not suitable for everyone: avoid it if you have a stomach ulcer, bleeding disorder, or aspirin-sensitive asthma. Aspirin must not be given to children or teenagers under 16 due to the risk of Reye's syndrome. Always read the label.

Why do I get a headache when I skip my morning coffee?

Caffeine withdrawal is one of the most common headache triggers. If your body is used to regular caffeine, skipping it causes blood vessels in the brain to widen, which can trigger a headache. This usually starts 12 to 24 hours after your last caffeine intake and can last one to two days. To avoid caffeine withdrawal headaches, reduce your intake gradually rather than stopping suddenly. Interestingly, small amounts of caffeine can also help treat headaches, which is why it is included in some headache products like Panadol Extra.

Are generic painkillers as effective as brand-name products?

Yes. In Australia, all medicines — generic and branded — must meet the same TGA standards for quality, safety, and effectiveness. A 200mg ibuprofen tablet from a pharmacy-own brand contains exactly the same active ingredient at the same dose as a branded Nurofen tablet. The main differences are in the inactive ingredients (binders, coatings) and the formulation (for example, liquid capsules may be absorbed slightly faster than standard tablets). For most headaches, a generic paracetamol or ibuprofen tablet will work just as well at a significantly lower cost.

When should I see a doctor about my headaches?

See your GP if your headaches are occurring on more than two days a week, are getting worse over time, are not adequately controlled by OTC medicines, are new and different from your usual headaches, or are affecting your ability to work or enjoy daily activities. You should also see a doctor if you need to take headache medicine more than two to three days per week to function normally.
