Yes, Aleve works for headaches. Its active ingredient, naproxen sodium, is a proven pain reliever for both tension headaches and migraines, and it’s rated as a Level A (effective) treatment for acute migraine by the American Headache Society. That said, it works better for some headache types than others, and it has a few characteristics that set it apart from other over-the-counter options.
How Aleve Relieves Headache Pain
Aleve belongs to the NSAID class of pain relievers, alongside ibuprofen (Advil) and aspirin. It works by blocking an enzyme called COX, which your body uses to produce prostaglandins, chemicals that trigger inflammation and amplify pain signals. By cutting off prostaglandin production, naproxen reduces both the inflammation and the pain signaling that make your head throb.
Naproxen also acts within the central nervous system, where it dampens pain signals at the spinal cord level and influences the turnover of brain chemicals involved in pain processing. For migraines specifically, research shows it can reduce the activation and sensitization of pain-sensing nerves around the membranes covering the brain, which is a key driver of migraine pain. It reaches peak levels in your bloodstream in about two hours after you take it.
How Well It Works for Different Headaches
For tension headaches, the most common type, Aleve is a standard and generally effective choice. Most people with mild to moderate tension headaches get meaningful relief within one to two hours.
For migraines, the picture is more nuanced. A Cochrane systematic review found that naproxen (500 mg to 825 mg) outperformed placebo, with about 45% of people experiencing headache relief at two hours compared to 29% on placebo. However, only about 17% of people were completely pain-free at two hours, versus 8% on placebo. Over a full 24-hour period, about 30% had sustained headache relief. Those numbers make naproxen statistically better than nothing for migraines, but the review concluded it’s not particularly strong as a standalone migraine treatment. If you get occasional mild migraines, Aleve may be enough. For moderate to severe migraines, many people need something stronger or a combination approach.
Aleve vs. Ibuprofen and Acetaminophen
The biggest practical advantage of Aleve over other OTC pain relievers is how long it lasts. You take Aleve every 8 to 12 hours, while ibuprofen and acetaminophen typically need to be re-dosed every 4 to 6 hours. If your headaches tend to linger or come back later in the day, that longer duration can make a real difference.
The tradeoff is speed. Ibuprofen tends to kick in a bit faster than naproxen, which takes closer to two hours to reach full effect. Acetaminophen (Tylenol) works differently altogether. It’s not an anti-inflammatory, so it won’t address headaches driven by inflammation, but it’s gentler on the stomach and safer for people who can’t take NSAIDs. For a straightforward tension headache, all three are reasonable choices. Your pick often comes down to whether you prioritize faster onset or longer-lasting relief.
Dosing for Headaches
Aleve sells a product specifically labeled “Aleve Headache Pain,” though the active ingredient is the same naproxen sodium found in regular Aleve. Each tablet contains 220 mg of naproxen sodium. The recommended dosing for adults and children 12 and older is:
- First dose: You can take up to 2 tablets within the first hour.
- Ongoing doses: 1 tablet every 8 to 12 hours while symptoms last.
- Daily maximum: No more than 3 tablets in a 24-hour period.
Don’t exceed 2 tablets in any 8- to 12-hour window. Taking more than the recommended amount increases your risk of stomach and cardiovascular side effects without meaningfully improving pain relief.
Medication Overuse Headaches
One of the most important things to know about using any pain reliever for headaches is the risk of rebound headaches, formally called medication overuse headaches. If you take NSAIDs like Aleve on 15 or more days per month, your brain can adapt in ways that actually make headaches more frequent and harder to treat. You end up in a cycle where the medication that’s supposed to help is perpetuating the problem.
This threshold applies to all simple analgesics and NSAIDs, not just Aleve. If you find yourself reaching for headache relief more than two or three days a week on a regular basis, that’s a signal to talk to a healthcare provider about preventive strategies rather than continuing to treat each headache as it comes.
Stomach and Heart Considerations
Like all NSAIDs, naproxen can irritate the stomach lining, potentially causing nausea, heartburn, or in more serious cases, ulcers and gastrointestinal bleeding. Taking it with food or a glass of water helps reduce stomach irritation. People with a history of stomach ulcers or GI bleeding should be especially cautious.
NSAIDs also carry a small increased risk of cardiovascular events like heart attack and stroke, particularly with long-term use. Naproxen is generally considered to have a more favorable cardiovascular safety profile compared to some other NSAIDs, but the risk isn’t zero. People with existing heart disease or high blood pressure should be aware of this. Each Aleve tablet also contains 220 mg of sodium, which is worth noting if you’re on a sodium-restricted diet.
Aleve should not be taken right before or after heart surgery, and it’s not recommended for children under 12 without medical guidance.
