Standard Aleve Dosage for Adults

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 for the first dose, then one tablet every 12 hours after that. Most people take one tablet and wait to see if it works before taking another. Do not exceed two tablets in 24 hours unless a doctor tells you otherwise.

Aleve tablets come in 220 mg strength (naproxen base). The sodium version dissolves faster and works within 30 minutes for many people, while the regular formulation takes 45 minutes to an hour. If you have taken other pain relievers that day — ibuprofen, aspirin, or acetaminophen — do not add Aleve on top of them.

Key Takeaways

  • Take one Aleve tablet every 8 to 12 hours, with a maximum of two tablets in your first 24 hours, then one tablet every 12 hours after that.
  • Do not take Aleve with other nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin on the same day.
  • Aleve is meant for short-term use only — if you need pain relief for more than 10 days, talk to a doctor before continuing.
  • People with heart disease, high blood pressure, kidney problems, or a history of stomach ulcers should not take Aleve without checking with their doctor first.
  • Aleve can interact with blood thinners, certain blood pressure medications, and some other drugs, so review your current medications before taking it.

Why You Should Not Double Up on Pain Relievers

Taking Aleve together with ibuprofen (Advil, Motrin), naproxen (Naprosyn), or aspirin on the same day increases your risk of stomach bleeding, ulcers, and kidney damage. All of these are NSAIDs, and combining them does not make the pain relief stronger — it only raises the danger.

Acetaminophen (Tylenol) works differently and is technically safe to combine with Aleve, but most doctors recommend against it because the combination does not work better than either drug alone. If one dose of Aleve is not enough, wait the full 8 to 12 hours before taking another, rather than adding a second pain reliever.

When Not to Take Aleve Without Talking to a Doctor

Aleve is not safe for everyone. Do not take it if you have a history of stomach ulcers, heart disease, high blood pressure, kidney disease, or asthma triggered by NSAIDs. If you are over 65, your doctor may recommend a lower dose or a different pain reliever altogether, because older adults are more likely to have side effects.

Tell your doctor before taking Aleve if you take blood thinners (warfarin, apixaban, dabigatran), ACE inhibitors or ARBs for blood pressure, diuretics, lithium, or methotrexate. Aleve can reduce how well these drugs work or increase the risk of serious side effects. Your doctor may suggest a different pain reliever or adjust your other medications.

How Long You Can Safely Take Aleve

Aleve is meant for short-term pain relief only. The label says to use it for no more than 10 days unless a doctor tells you otherwise. If you have been taking it for 10 days and the pain is still there, stop and see a doctor instead of continuing on your own.

Long-term use of NSAIDs like Aleve raises the risk of stomach bleeding, heart attack, and stroke, especially if you take it every day for weeks or months. If you have chronic pain that needs daily relief, your doctor can recommend safer options or monitor you more closely while you take Aleve.

Signs You Should Stop Taking Aleve and See a Doctor

Stop taking Aleve and seek medical attention if you experience severe stomach pain, vomit blood or material that looks like coffee grounds, have black or bloody stools, feel short of breath, have chest pain, or notice unusual bruising or bleeding. These are signs of serious side effects that need when ready care.

Milder side effects — heartburn, nausea, dizziness, or headache — may go away on their own, but if they persist or get worse, talk to your doctor. Some people also experience rash, swelling of the face or throat, or difficulty breathing, which are signs of an allergic reaction and require emergency care.

Aleve Versus Other Over-the-Counter Pain Relievers

Aleve lasts longer than ibuprofen or aspirin because naproxen stays in your body for 12 to 17 hours. This means you take fewer doses per day, which some people find more convenient. However, the longer duration also means side effects take longer to wear off if they occur.

Ibuprofen (Advil, Motrin) works faster — usually within 30 minutes — and you can take it every 4 to 6 hours, up to three or four times a day. Acetaminophen (Tylenol) is gentler on the stomach but does not reduce inflammation the way NSAIDs do. For headaches and fever, acetaminophen often works just as well as Aleve and may be safer if you have stomach or heart concerns.

Reading the Aleve Label Correctly

The Aleve package label lists the dose as "one tablet every 8 to 12 hours" and a maximum of two tablets in 24 hours for the first dose. This means you take one tablet, and if you need more relief, you can take another tablet 8 to 12 hours later — but not sooner. After the first 24 hours, the maximum drops to one tablet every 12 hours.

Some Aleve products are labeled differently — Aleve PM, for example, combines naproxen with a sleep aid and has different dosing. Always read the label on the specific product you bought, because dosing can vary. If the label is unclear or you are unsure, ask a pharmacist before taking it.

Frequently Asked Questions

Can I take two Aleve tablets at once instead of spacing them out?

No. The label says one tablet every 8 to 12 hours. Taking two at once does not make it work faster or better — it only increases the risk of side effects. Take one tablet and wait at least 8 hours before taking another.

What if I missed a dose and it is almost time for the next one?

Skip the missed dose and take your next dose at the regular time. Do not take two doses at once to make up for a missed one. Stick to the 8 to 12 hour spacing going forward.

Is Aleve safe to take every day for chronic pain?

No. Aleve is for short-term use only — up to 10 days without a doctor's approval. If you have pain that lasts longer than 10 days, see a doctor instead of taking Aleve daily on your own. Long-term daily use raises the risk of stomach bleeding, heart problems, and kidney damage.

Can I take Aleve with food to protect my stomach?

Taking Aleve with food or milk may reduce stomach upset, but it does not prevent serious side effects like ulcers or bleeding. If you have a history of stomach problems, talk to your doctor before taking Aleve at all, rather than relying on food to make it safe.

Why does Aleve last longer than ibuprofen?

Naproxen (the active ingredient in Aleve) stays in your bloodstream for 12 to 17 hours, while ibuprofen leaves your body in 4 to 6 hours. This longer duration means fewer doses per day, but it also means side effects take longer to wear off if they happen.
