Aleve, the brand name for over-the-counter naproxen sodium, is an effective option for both tension-type headaches and migraines, backed by multiple clinical trials and systematic reviews. It works more slowly than some alternatives but lasts longer, which gives it a practical edge when you want relief that holds through the day. The trade-off, as with all anti-inflammatory painkillers, involves real risks to your stomach, kidneys, and blood pressure that scale with dose and duration.
How Naproxen Sodium Relieves Headache Pain
Naproxen sodium belongs to the class of nonsteroidal anti-inflammatory drugs, or NSAIDs. It works by blocking an enzyme called cyclooxygenase, which your body uses to produce prostaglandins. Prostaglandins play a direct role in triggering and sustaining headache pain, particularly in migraine, where they contribute to the inflammation and blood vessel changes that drive an attack.1PubMed Central. NSAIDs in the Acute Treatment of Migraine: A Review of Clinical and Experimental Data By cutting off that production, naproxen reduces both the pain and the inflammation fueling it.
Aleve specifically contains naproxen sodium rather than plain naproxen. The sodium salt dissolves faster in your stomach, which means it gets absorbed into your bloodstream more quickly. Once absorbed, it behaves identically to regular naproxen. The two forms are therapeutically equivalent at comparable doses, but the faster absorption of the sodium form makes it better suited for acute pain like headaches, where you want relief to start as soon as possible.2Current Therapeutic Research. Bioequivalence of 2 Naproxen Sodium Tablet Formulations in Healthy Male and Female Volunteers Plain naproxen, by contrast, is more commonly prescribed for chronic conditions like arthritis where the speed of the first dose matters less.
Effectiveness for Tension-Type Headaches
Tension-type headaches are the most common kind, and naproxen handles them well. In a randomized, double-blind trial comparing naproxen 375 mg against acetaminophen 1000 mg and placebo in people with moderate-to-severe tension-type headaches, both active drugs significantly outperformed placebo in reducing pain. Naproxen and acetaminophen performed similarly to each other, with no meaningful difference between the two.3PubMed. Efficacy and safety of acetaminophen and naproxen in the treatment of tension-type headache. A randomized, double-blind, placebo-controlled trial For a garden-variety tension headache, Aleve will likely work about as well as Tylenol, with the added benefit of lasting longer per dose.
Where naproxen has a practical advantage over acetaminophen is its anti-inflammatory action. Acetaminophen is a pain reliever but not a true anti-inflammatory, so for headaches that involve inflammation or muscle tension in the neck and scalp, naproxen can address more of what is going on. That said, for a mild headache with no inflammatory component, either one will usually do the job.
Effectiveness for Migraine
The evidence for naproxen sodium in migraine is solid, though the effect size is moderate. A meta-analysis pooling data from multiple trials found that naproxen sodium was significantly more effective than placebo for reducing migraine pain and achieving a pain-free state within two hours. People taking naproxen were roughly twice as likely to be pain-free at two hours compared to those on placebo, and about 60% more likely to experience headache relief at the same time point.4PubMed. Meta-analysis of the efficacy and safety of naproxen sodium in the acute treatment of migraine
A Cochrane review put more precise numbers on the picture. At two hours after taking 500 mg of naproxen, about 17% of people were completely pain-free, compared with 8% on placebo. For headache relief (meaning pain dropped to mild or disappeared), the numbers were 45% on naproxen versus 29% on placebo. Over a full 24-hour period, about 30% of naproxen users had sustained headache relief, versus 18% on placebo.5Cochrane Database of Systematic Reviews. Naproxen with or without an antiemetic for acute migraine headaches in adults Those numbers mean naproxen works, but it is not a powerhouse for migraine on its own. You would need to treat about 11 migraine sufferers for one additional person to become pain-free at two hours, beyond what placebo would achieve. Compared to triptans, naproxen is a more modest performer, but it is available without a prescription and carries a different risk profile, which matters for people who use it occasionally.
OTC Dosing for Headaches
Each Aleve tablet or liquid gel contains 220 mg of naproxen sodium. The standard OTC dosing for adults is one tablet (220 mg) every 8 to 12 hours, with the option to take two tablets (440 mg) as an initial dose if needed. The maximum over-the-counter daily dose is typically three tablets (660 mg) in a 24-hour period. Do not exceed that without a doctor’s direction.
A meta-analysis examining OTC naproxen sodium across a range of doses (220 mg up to 880 mg, in single and multiple-dose regimens) confirmed a favorable safety profile at OTC doses, with the overall rate of side effects comparable to placebo and in some cases lower.6Journal of Clinical Pharmacology. A look at the safety profile of over-the-counter naproxen sodium: a meta-analysis The clinical trials for migraine often used 500 mg, which is a prescription-level dose. If OTC dosing does not manage your migraines, your doctor can prescribe a higher dose, but higher doses carry more risk.
Timing matters too. Taking naproxen at the first sign of a headache tends to produce better results than waiting until the pain is well established. This is especially true for migraine, where early treatment is consistently linked to higher pain-free rates.
Stomach and Digestive Risks
The biggest safety concern with naproxen, and all NSAIDs, is the stomach. NSAIDs can irritate the lining of the digestive tract and increase the risk of ulcers and bleeding. A large overview of epidemiologic studies found that naproxen use was associated with roughly a fourfold increase in the risk of upper gastrointestinal bleeding, with a clear dose-dependent relationship: lower doses carried a risk about 3.5 times that of non-users, while higher doses pushed that to about five times.7Archives of Internal Medicine. Association Between Nonsteroidal Anti-inflammatory Drugs and Upper Gastrointestinal Tract Bleeding/Perforation: An Overview of Epidemiologic Studies Published in the 1990s
For occasional headache use at OTC doses, the absolute risk to a healthy person is low. These elevated risk ratios are most worrying for people who take NSAIDs regularly or at higher doses. A trial comparing naproxen to celecoxib (a different type of anti-inflammatory) in patients who already had a history of GI bleeding found that recurrent bleeding was significantly more common with naproxen: about 12% of naproxen users experienced recurrent upper GI bleeding over 18 months, compared with roughly 6% on celecoxib.8The Lancet. Celecoxib versus naproxen and esomeprazole in patients with arthritis at high risk of cardiovascular and gastrointestinal events (CONCERN) That study focused on a high-risk population using daily doses for arthritis, not occasional headache treatment, but it highlights why chronic use requires medical supervision.
You can reduce your stomach risk by taking Aleve with food, using the lowest effective dose, and keeping the duration of use short. If you have a history of stomach ulcers or GI bleeding, talk to your doctor before using any NSAID.
Heart and Blood Pressure Considerations
Naproxen has long been considered one of the friendlier NSAIDs for the cardiovascular system. Its relatively low selectivity for one of the cyclooxygenase enzymes (COX-2) appears to give it a lower cardiovascular risk profile compared to several other NSAIDs.9PubMed Central. Clinical Pharmacology and Cardiovascular Safety of Naproxen A large randomized trial comparing naproxen, ibuprofen, and celecoxib in over 24,000 arthritis patients found similar cardiovascular event rates across all three drugs, with no significant differences in heart attacks, strokes, or cardiovascular deaths.10PubMed. Cardiovascular Safety of Celecoxib, Naproxen, or Ibuprofen for Arthritis So while naproxen was once thought to be clearly safer for the heart than ibuprofen, the current evidence suggests the differences are small in practice.
Blood pressure is a separate concern. Naproxen, along with certain other NSAIDs like indomethacin, has been linked to clinically meaningful increases in blood pressure.11Clinical Therapeutics. The impact of nonsteroidal anti-inflammatory drugs on blood pressure, with an emphasis on newer agents For someone popping a single dose for a headache once in a while, this is unlikely to be a problem. But if you have high blood pressure or take blood pressure medication, be aware that regular NSAID use can push your readings up and interfere with your treatment.
Combining Aleve With Prescription Migraine Drugs
One of the most clinically interesting uses of naproxen sodium for headaches is in combination with sumatriptan, a prescription triptan drug. Multiple trials have shown that taking sumatriptan together with naproxen sodium produces substantially better results than either drug alone. In one trial, the combination delivered a 24-hour pain relief rate of 46%, compared with 29% for sumatriptan alone, 25% for naproxen alone, and 17% for placebo. The two-hour headache response rate with the combination was 65%, versus 49% for sumatriptan and 46% for naproxen on their own.12PubMed. Sumatriptan and naproxen sodium for the acute treatment of migraine
These findings were confirmed in a larger randomized trial and a Cochrane review. The Cochrane analysis found that treating early, while migraine pain was still mild, significantly improved the results. When people took the combination at the mild-pain stage, about half were pain-free at two hours. When they waited until pain was moderate or severe, that dropped to about 28%.13PubMed Central. Sumatriptan plus naproxen for the treatment of acute migraine attacks in adults The combination also caused fewer side effects than sumatriptan alone, because naproxen’s side-effect profile is milder than sumatriptan’s at these doses. A combined tablet (sumatriptan 85 mg plus naproxen sodium 500 mg) is available by prescription under the brand name Treximet.14JAMA.

Menstrual Migraine Prevention
Naproxen sodium has a specific niche in preventing migraines tied to the menstrual cycle. Unlike typical acute treatment where you take the drug after pain starts, this approach involves taking naproxen daily around the time of menstruation to prevent attacks from occurring. A study of women with pure menstrual migraine found that taking 550 mg of naproxen sodium daily for a window around their period significantly reduced the number of attacks, their duration, and their intensity over six months of treatment. Attack frequency dropped from about 1.7 per cycle to 1.1, and duration fell from roughly 26 hours to about 13 hours.15PubMed. Naproxen sodium in short-term prophylaxis of pure menstrual migraine: pathophysiological and clinical considerations
A double-blind, placebo-controlled study supported these findings, showing that naproxen sodium 550 mg twice daily for three months significantly reduced headache intensity, duration, and the amount of rescue painkillers women needed, compared with placebo. Tolerability was good, and the drug also helped with premenstrual pain.16PubMed. Naproxen sodium in menstrual migraine prophylaxis: a double-blind placebo controlled study This short-term preventive use is worth discussing with your doctor if your migraines predictably cluster around your period.
Adolescents and Older Adults
For teenagers, the combination of sumatriptan and naproxen sodium has been studied specifically. In a randomized trial of adolescents aged 12 to 17 with migraine, multiple dose levels of the combination significantly outperformed placebo. The two-hour pain-free rates ranged from about 24% to 29% with the active drug versus 10% with placebo, and the treatment was well tolerated.17Pediatrics. Randomized Trial of Sumatriptan and Naproxen Sodium Combination in Adolescent Migraine A longer-term follow-up study found that about 42% of migraine attacks in adolescents were pain-free within two hours of taking the combination, and participants generally reported satisfaction with treatment over time.18PubMed. Long-term evaluation of sumatriptan and naproxen sodium for the acute treatment of migraine in adolescents Standard Aleve (naproxen sodium alone) is generally considered appropriate for children 12 and older at OTC doses, though younger children should use it only under medical guidance.
Older adults face a different risk landscape. Chronic NSAID use in this population increases the risk of peptic ulcer disease, acute kidney failure, and stroke or heart attack. NSAIDs can also worsen heart failure and hypertension, and they interact with medications that older adults commonly take, such as blood thinners and corticosteroids.19PubMed Central. Recognizing the Risks of Chronic Nonsteroidal Anti-Inflammatory Drug Use in Older Adults Occasional use for a headache can still be reasonable for a healthy older person, but chronic or frequent use should be discussed with a doctor, and the lowest effective dose should always be the goal.
Alcohol, Drug Interactions, and Overuse
Mixing Aleve with alcohol is riskier than many people realize. A study examining OTC NSAID use alongside alcohol abuse found that the combination produced a gastrointestinal bleeding risk greater than you would expect from simply adding the two individual risks together. Using ibuprofen or naproxen without alcohol roughly doubled the risk of GI events, while alcohol abuse alone increased it by about 2.4 times. But using both OTC NSAIDs and alcohol together pushed the risk to about 6.5 times the baseline, which is more than the sum of the parts.20PubMed. The effect of alcohol abuse on the risk of NSAID-related gastrointestinal events That study focused on alcohol abuse rather than a single glass of wine, but the interaction is real and worth taking seriously if you drink regularly.
Beyond alcohol, naproxen can interact with a range of common medications. Drug interactions have been documented when NSAIDs are taken alongside aspirin, certain blood pressure medications, and antidepressants.21PubMed Central. Adverse drug reactions and drug-drug interactions with over-the-counter NSAIDs The aspirin interaction is particularly worth knowing about: if you take low-dose aspirin for heart protection, taking naproxen around the same time can interfere with aspirin’s ability to prevent blood clots. The typical advice is to take aspirin at least 30 minutes before or eight hours after naproxen, though your doctor can give you specific timing guidance.
There is also the problem of overuse. Taking any painkiller too frequently for headaches, whether it is naproxen, acetaminophen, ibuprofen, or a triptan, can paradoxically lead to more headaches. This condition, known as medication-overuse headache, tends to develop when acute headache treatments are used more than about 10 to 15 days per month. The headaches become more frequent over time, creating a cycle where the drug that once helped becomes part of the problem.22Neurologic Clinics. Role and impact of over-the-counter medications in the management of headache If you find yourself reaching for Aleve more than two or three times a week for headaches, that is a signal to see a doctor about preventive treatment rather than continuing to rely on acute relief.
