Naproxen (Aleve) for Headache: How Much, How Often, and When to Stop

Over the counter, naproxen sodium comes as 220 mg tablets sold as Aleve. The label directs one tablet every 8 to 12 hours, with an option of two for the first dose, and no more than three tablets (660 mg) in 24 hours. Its advantage over ibuprofen is duration: one dose covers 8 to 12 hours instead of 4 to 6. Its disadvantage is the same thing, because everything an NSAID does to your stomach and kidneys, it does for longer.

Naproxen is the painkiller most people reach for third, after ibuprofen and Tylenol, and it is the one they understand least. This page covers the dose, what it is genuinely good at, the questions people actually ask about it, and what to do on the days it is not an option.

What naproxen is, in one line

Naproxen is an NSAID, a non-steroidal anti-inflammatory drug, the same class as ibuprofen and aspirin. It blocks COX enzymes, which lowers prostaglandins, which reduces pain and inflammation. It is cleared largely through the kidneys.

The single thing that separates it from ibuprofen is how long it lasts. Naproxen has a half-life of roughly 12 to 17 hours. Ibuprofen's is about 2 hours. That is the whole reason one is dosed twice a day and the other every four to six hours.

Because both are NSAIDs, they are not two options to alternate between. They are the same tool in two lengths.

Is naproxen a very strong painkiller?

Not in the way people mean when they ask this. Naproxen is not stronger than ibuprofen in the sense of relieving more pain at a comparable dose. It is longer.

If you are comparing the standard over-the-counter doses, 220 mg of naproxen and 400 mg of ibuprofen land in broadly similar territory for pain relief. The difference a person actually notices is that the naproxen dose is still working at hour six, when the ibuprofen dose has faded.

"Strong" in the pharmacy sense usually means opioid, and naproxen is not one. It is an anti-inflammatory available on a supermarket shelf.

Is naproxen 500 mg a strong painkiller?

500 mg is the common prescription strength, and it is more than double the over-the-counter tablet. It is used for conditions where inflammation is the main driver of pain, and it is prescribed rather than sold over the counter for a reason: the risks to the stomach, kidneys and cardiovascular system scale with dose and with duration.

It is not a dose to build toward by taking extra Aleve. Two 220 mg tablets is 440 mg and is already the label's maximum single dose.

What is the downside of Aleve?

Three things, and the third is the one that catches headache sufferers specifically.

• It stays in your system. The property that makes it convenient also means an NSAID is acting on your stomach lining and kidneys for 12 hours rather than four. For occasional use that is a fair trade. For repeated use it is the argument against naproxen rather than for it.
• It carries the full NSAID risk profile. Stomach irritation and bleeding risk, strain on kidney function, fluid retention and raised blood pressure. The FDA requires a boxed warning on NSAIDs for cardiovascular events and gastrointestinal bleeding. None of this is unique to naproxen, but the longer exposure per dose is worth knowing about.
• It counts toward medication overuse headache. More on that below, and it is the reason the "what do I take instead" question exists at all.

Talk to a pharmacist before making naproxen a regular part of how you handle headaches, particularly if you take anything else daily.

What should you not mix with Aleve?

The short version: any other NSAID, and anything that raises bleeding risk.

• Ibuprofen, aspirin, celecoxib, diclofenac. All NSAIDs. Stacking them multiplies the risk to your stomach and kidneys and adds very little relief. This is the most common mistake, because people think of Advil and Aleve as different things.
• Blood thinners such as warfarin or apixaban, and daily low-dose aspirin taken for the heart.
• SSRI antidepressants, which raise gastrointestinal bleeding risk on their own. Combining them with an NSAID raises it further.
• Alcohol, in quantity, for the same stomach reasons.
• Check with a pharmacist if you take blood pressure medication, lithium, methotrexate or diuretics.

Acetaminophen (Tylenol) is the exception. It is not an NSAID, it is cleared by the liver rather than the kidneys, and for most healthy adults the two can be combined. If you are already at your naproxen ceiling for the day, that is the one thing you can add.

Why don't doctors like to prescribe naproxen?

The premise is not quite right. Naproxen is prescribed constantly, particularly for arthritis and for conditions where a long-acting anti-inflammatory is exactly what is wanted.

What is true is that doctors get more cautious about NSAIDs the longer the intended course runs, and naproxen's duration means each dose carries longer exposure. Caution increases sharply with reduced kidney function, a history of ulcers or gastrointestinal bleeding, heart failure, uncontrolled high blood pressure, or blood thinners.

For headache in particular there is a second reason. Frequent NSAID use is one of the routes into medication overuse headache, so a doctor looking at someone with regular headaches is often thinking about prevention rather than a longer-acting painkiller.

Can you take naproxen while pregnant?

The FDA recommends avoiding NSAIDs from around 20 weeks of pregnancy, because they can cause fetal kidney problems and low amniotic fluid, and advises avoiding them entirely after 30 weeks. That guidance covers naproxen along with ibuprofen and aspirin.

Acetaminophen is generally the first-line option in pregnancy. Drug-free approaches carry no dosing limit and can be used alongside. Confirm anything with your OB or midwife rather than with a page on the internet.

When naproxen stops being the answer

Here is the part that matters most for anyone reading this because they get headaches often rather than occasionally.

Taking pain relief too frequently can start causing the headaches it is meant to stop. Medication overuse headache begins at 15 or more days a month for simple painkillers such as naproxen, ibuprofen or acetaminophen alone, and at 10 or more days a month for combination products such as Excedrin, sustained over three months.

Alternating between different painkillers does not reset the count. Naproxen on Monday and ibuprofen on Wednesday is two days, not one of each.

Most headache specialists suggest keeping pain relief under about two days a week. Which leaves the obvious question of what happens on the other five.

What to do on the days naproxen is not an option

Whether you have hit your daily ceiling, you are pregnant, you take a blood thinner, or you simply do not want to take another tablet, the same set of approaches applies. None of them carry a daily limit.

• Address the cause when the cause is addressable. Dehydration and skipped meals are two of the most common headache triggers and the fastest to reverse. Water, something salty, and food. If a headache lifts within half an hour of that, you have learned something useful about your own pattern.
• Cold or pressure applied to the head. An ice pack on the forehead or the back of the neck, a cooling gel patch, a compression cap, or a drug-free adhesive patch such as Migraine AID, which works by negative pressure: a patented adhesive design that gently lifts the skin to reduce pressure at the surface. It is single-use, has a dermatologist-reviewed adhesive, and contains no medication, cooling gel or numbing agent, so it can be layered with whatever else you are already doing. Because there is no drug in it, it does not count toward the medication overuse thresholds above, and it does not interact with naproxen, an SSRI, a blood thinner or anything else in your cabinet. That is the practical reason a physical option belongs in this conversation rather than another pill.
• A dark, quiet room, which remains one of the most effective options for migraine specifically.
• Magnesium, which has reasonable evidence behind it for reducing migraine frequency over time. Prevention rather than rescue.
• Acupressure at the temples, the base of the skull, or the web between thumb and index finger.
• Consistent sleep timing, which matters more than total hours for many people.
• FDA-cleared neuromodulation devices such as Cefaly or Nerivio, where headaches are frequent enough to justify the cost.

How the drug-free options compare

Worth knowing what each one actually does, because they work in different ways and suit different people.

None of these are a substitute for medical treatment of frequent migraine. They exist for the days when medication is not available to you, or you would rather not take more of it.

If you are consistently hitting the frequency thresholds, the useful next step is a conversation with a doctor about prevention, not a different tablet.

Frequently asked questions

Can you take naproxen and ibuprofen together?

No. Both are NSAIDs, so taking them together doubles the risk profile without adding meaningful relief. If you have taken one and it is not working, the answer is not the other one. Acetaminophen is the option that can be combined, because it works by a different route and is cleared by a different organ.

How long does Aleve take to work?

Generally around an hour for the effect to become noticeable, with the peak somewhat later. The trade for that slower start is the longer tail: one dose covers 8 to 12 hours rather than 4 to 6.

Can you take Aleve every day?

The label directs users not to take it for pain for more than 10 days without speaking to a doctor. Beyond the label, daily NSAID use raises the risk of stomach bleeding, kidney strain and higher blood pressure over time, and for people who get headaches it can tip into medication overuse headache. Daily use is a reason to talk to a doctor about prevention.

Is Aleve or Advil better for a headache?

Neither is stronger. Aleve lasts longer per dose, Advil starts working sooner and is easier to fit around a short-lived headache. For a headache that arrives and clears in a few hours, the shorter-acting option often makes more sense. For one that has been grinding on all day, the longer one does.

What can I take for a headache if I can't take NSAIDs at all?

Acetaminophen is the usual alternative for most people, since it is not an NSAID. Alongside that, the physical approaches above apply without a daily limit, which is why a drug-free option like Migraine AID is worth having in the drawer for exactly this situation. Talk to a pharmacist about your own circumstances.
