Standard dosing for Aleve

The standard dose of Aleve (naproxen sodium) is one tablet every 8 to 12 hours, with a maximum of two tablets in a 24-hour period on the first day, then one tablet every 12 hours after that. Do not exceed two tablets in any 24-hour period once you move past the first day. Each tablet contains 220 mg of naproxen sodium, which is equivalent to 200 mg of naproxen base.

This dosing applies to the over-the-counter strength Aleve sold in most drugstores and supermarkets. The spacing between doses matters: taking two tablets closer together than 8 hours apart increases your risk of stomach upset and other side effects without making the medication work better. If you need pain relief more frequently than every 8 hours, Aleve is not the right choice for your situation.

Never take more than the package label directs. The two-tablet daily limit exists because naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can damage your stomach lining, kidneys, and heart if you take too much over time.

Key Takeaways

  • Take one Aleve tablet every 8 to 12 hours, with a maximum of two tablets in the first 24 hours and one tablet per 12 hours after that.
  • Do not exceed two tablets in any single 24-hour period once you pass the first day, even if your pain returns sooner.
  • Aleve is meant for short-term use only — if you need it for more than 10 days, talk to a doctor before continuing.
  • Certain medical conditions and medications make Aleve unsafe; check the label warnings or ask a pharmacist if you take other drugs or have heart, kidney, or stomach problems.

Why the dosing limits exist

Naproxen stays in your body longer than other over-the-counter pain relievers like ibuprofen or acetaminophen. Because it has a long half-life — the time it takes your body to eliminate half the dose — taking it too frequently or in large amounts causes the drug to build up in your system. This buildup increases the risk of serious side effects, particularly to your stomach and digestive tract.

NSAIDs like Aleve can cause bleeding ulcers, especially if you take them regularly or in high doses. They also raise your risk of heart attack and stroke, and can damage your kidneys if you use them long-term or take too much at once. The two-tablet daily limit is designed to keep you in a safe range for occasional use.

When you should not take Aleve or need a different dose

Do not take Aleve if you are allergic to naproxen or other NSAIDs, or if you have a history of stomach ulcers, heart disease, high blood pressure, kidney disease, or asthma. Aleve is also unsafe if you are in the last three months of pregnancy. If any of these explore to you, talk to a doctor or pharmacist about what pain reliever is safe instead.

Certain medications interact dangerously with Aleve, including blood thinners, some blood pressure drugs, and certain arthritis medications. If you take any prescription medications, ask your pharmacist whether Aleve is safe to combine with them before you take your first dose. Do not assume it is safe just because it is sold over the counter.

People over 65 should use Aleve only under a doctor's supervision, as older adults are at higher risk for stomach bleeding and kidney problems from NSAIDs. If you have mild kidney disease or take diuretics, Aleve may not be appropriate for you at all.

How long you can take Aleve

Aleve is intended for short-term pain relief only. The label directs you not to use it for more than 10 days unless a doctor tells you it is safe to continue. Many people mistakenly believe that because Aleve is available without a prescription, it is safe to take indefinitely. That is not true.

If your pain lasts longer than 10 days, or if you need to take Aleve regularly, contact a doctor. Long-term NSAID use — even at the correct dose — increases your risk of serious complications. A doctor can determine whether Aleve is appropriate for your situation or whether you need a different approach, such as a prescription-strength NSAID with stomach protection, or a non-NSAID pain reliever.

What to do if you take too much Aleve

If you accidentally take more than two tablets in 24 hours, do not panic, but do monitor yourself for signs of overdose. Symptoms include stomach pain, nausea, vomiting, drowsiness, or black or bloody stools. If you experience any of these, contact Poison Control at 1-800-222-1222 (available 24 hours, free, confidential) or go to an emergency room.

If you took significantly more than the recommended dose — for example, if a child got into a bottle — call Poison Control when ready rather than waiting to see if symptoms develop. They can tell you whether you need medical attention based on the amount taken and your age and weight.

Aleve versus other over-the-counter pain relievers

Aleve differs from ibuprofen (Advil, Motrin) and acetaminophen (Tylenol) in how long it lasts and how often you can take it. Because naproxen has a longer half-life, you take it less frequently — every 8 to 12 hours instead of every 4 to 6 hours. This can be convenient if you want longer-lasting relief, but it also means the drug stays in your system longer and carries a higher risk of side effects if you take too much.

Ibuprofen allows more frequent dosing (every 4 to 6 hours, up to 1,200 mg per day over the counter) and leaves your body faster, making it safer for some people. Acetaminophen works differently — it is not an NSAID — and does not carry the same stomach and heart risks, though it can damage your liver if you exceed the daily limit. The right choice depends on your medical history, what other medications you take, and how long you need relief.

Reading the Aleve label correctly

The Aleve package label is the source of truth for dosing. It clearly states the maximum number of tablets per day and the minimum time between doses. Some people misread the label or assume that because they feel fine, they can take more. The absence of when ready symptoms does not mean the drug is not building up in your system or causing hidden damage.

If the label is hard to read or you are unsure about the instructions, ask a pharmacist. They can explain the dosing in plain language and tell you whether Aleve is safe for your specific situation. This conversation takes five minutes and can prevent serious complications.

Frequently Asked Questions

Can I take Aleve every day?

No. Aleve is meant for short-term use only — no more than 10 days without a doctor's approval. Taking it daily, even at the correct dose, increases your risk of stomach bleeding, heart problems, and kidney damage. If you have chronic pain that requires daily medication, talk to a doctor about safer long-term options.

What happens if I take two Aleve tablets at once instead of spacing them?

Taking two tablets at the same time instead of spacing them 8 to 12 hours apart gives you a higher dose in your bloodstream at once, which increases the risk of stomach upset, nausea, and other side effects. It does not make the medication work better or faster. Always follow the spacing instructions on the label.

Is Aleve safe if I have high blood pressure?

Aleve can raise blood pressure and is not recommended for people with high blood pressure without a doctor's approval. If you have hypertension, ask your doctor or pharmacist which pain reliever is safe for you before taking Aleve. They may suggest acetaminophen or a different option instead.

Can I take Aleve with other medications?

Some medications interact dangerously with Aleve, including blood thinners, certain blood pressure drugs, and some arthritis medications. Before taking Aleve, tell your pharmacist about every prescription and over-the-counter medication you use. They can tell you in seconds whether it is safe to combine them.

What should I do if I missed a dose?

If you missed a dose, take the next dose when it is due according to the label — do not double up to make up for a missed dose. Aleve is not meant to be taken on a strict schedule like some medications; it is taken as needed for pain, spaced at least 8 hours apart, up to the daily maximum.
