Naproxen or Ibuprofen: Which Pain Reliever Suits Which Problem?

Naproxen (Aleve) and ibuprofen (Advil, Motrin) are both NSAIDs, and for many everyday aches either one can work. Ibuprofen is shorter acting, so it is often used when you want flexible dosing, such as for fever or a headache. Naproxen lasts longer between doses, which some people prefer for all-day aches like arthritis or cramps. This article compares them by problem, and explains who should ask a clinician first and which symptoms need emergency care.

Naproxen vs ibuprofen: which is better?

Neither is clearly better for everyone: both are NSAIDs of similar strength, and the main practical difference is how long each dose lasts. Both belong to the family called nonsteroidal anti-inflammatory drugs. Both can reduce pain, swelling and fever. For most minor problems, the better choice is less about which drug is stronger and more about how long you need relief, how often you are willing to take a dose, and what else is going on in your health.

A common rule of thumb, based on how long each drug lasts:

• Ibuprofen is shorter acting. It suits a fever, a tension headache, a toothache or a sore back where you may only need a dose or two.
• Naproxen lasts longer, so doses are spaced further apart. It may suit menstrual cramps, a sprain or a flare of arthritis pain that lingers through the day.

These are tendencies, not rules. People respond differently, and your own history with each drug counts for a lot. MedlinePlus (NIH) lists both under over-the-counter pain relievers and notes that NSAIDs share similar side effects and warnings: Pain Relievers.

What the two drugs have in common

NSAIDs work in part by blocking enzymes in the body called cyclooxygenases (COX), which help make chemicals involved in pain, inflammation and fever. The same enzymes also help protect the stomach lining and support blood flow to the kidneys. That overlap is why ibuprofen and naproxen share the same set of risks, even though they feel different in daily use.

Shared risks include:

• Stomach irritation, ulcers and bleeding
• Higher blood pressure and fluid retention in some people
• Strain on the kidneys, especially with dehydration or existing kidney disease
• Allergic reactions, including worsening asthma in some people with aspirin-sensitive asthma
• A possible increase in the chance of heart attack or stroke, which is why NSAID Drug Facts labels carry a warning about it (the review Cardiorenal Safety of OTC Analgesics, listed in Sources, discusses the evidence)

Because the risks overlap, taking ibuprofen and naproxen together does not add safety. It stacks the same risks. If one is not enough, ask a pharmacist or clinician what to try next rather than adding a second NSAID.

Side-by-side: how they differ in daily use

Typical adult over-the-counter limits

These are the amounts on the adult Drug Facts labels for Advil, Motrin and Aleve at the time of writing. Labels can change, and your product may differ, for example if it is a liquid, a coated tablet or a different strength, so the label on your bottle and your pharmacist have the final word. Higher amounts are prescription territory and belong with a clinician's direction.

• Ibuprofen (Advil, Motrin): usually 200 to 400 mg every 4 to 6 hours while symptoms last, with a ceiling of 1,200 mg in 24 hours unless a clinician directs otherwise.
• Naproxen sodium (Aleve): adult labels list one 220 mg tablet every 8 to 12 hours, and allow a larger first dose of two tablets (440 mg), with no more than 660 mg in 24 hours unless a clinician directs otherwise. Follow the label on your product.

Adult OTC labels generally limit use to 10 days for pain and 3 days for fever unless a clinician advises longer. Children's labels use shorter limits, so follow the product label and ask a pediatrician. A rectal temperature of 100.4°F (38°C) or higher in a baby younger than 3 months is an emergency: go to the emergency room, and do not give ibuprofen or naproxen to a young infant. Ibuprofen labels are not for babies under 6 months, and OTC naproxen is not for children under 12 unless a clinician directs it. Any fever or pain in an older child or adult that lasts past the label limit, or returns, is a reason to be evaluated rather than to keep dosing on your own.

Naproxen's long action makes accidental double dosing easy: a second dose taken sooner than the label allows, or a cold, sleep or "PM" product that also contains an NSAID, can push you past the daily limit. Check every active ingredient before adding another product. For children, amounts depend on the specific product and age directions, so follow the label and ask your pediatrician or pharmacist. Do not estimate a child's dose yourself.

Matching the drug to the problem

Headache and fever

Ibuprofen is a familiar choice here because its shorter action fits a problem that often passes. If a fever comes with a stiff neck, confusion, trouble breathing or a rash that does not fade when pressed, that needs urgent medical attention rather than a pain reliever.

Menstrual cramps

NSAIDs are commonly used for period pain because they reduce the prostaglandins that make the uterus cramp. MedlinePlus (NIH) lists pain relievers among the options for period pain, so check the page for its current wording: Period Pain. Either drug may help. Some people prefer naproxen because they take fewer doses across a day of cramping. Pain that is new, severe or getting worse over several cycles deserves a clinician visit.

Sprains, strains and sore muscles

For a twisted ankle or a pulled muscle, either drug may ease pain and swelling. Naproxen's longer action can be convenient for overnight comfort. Pain after a fall that makes it hard to bear weight, or a joint that looks deformed, calls for an exam and possibly an X-ray.

Arthritis and joint aches

For flares of osteoarthritis, either may help. Long-term use is a different conversation, because the risks of stomach bleeding, blood pressure changes and kidney strain tend to build with time. For knee or hand osteoarthritis, clinicians may also consider topical NSAIDs or the lowest effective amount for the shortest time; ask your clinician which option fits you. If you take an NSAID most days, tell your clinician so they can decide whether it is the right plan. Our article on daily ibuprofen for chronic pain covers that topic in more depth.

Back pain and nerve pain

NSAIDs can help with muscle-related back pain, but they are less reliable for nerve pain such as carpal tunnel syndrome, where other treatments are often tried first. MedlinePlus (NIH) covers that condition here: Carpal Tunnel Syndrome.

Who should ask a clinician before choosing either one

The label on every OTC NSAID tells people with certain conditions to check first. Tell your clinician or pharmacist about the following so they can decide whether an NSAID is appropriate for you:

• A history of stomach ulcers or GI bleeding. NSAIDs can irritate the stomach lining. See our article on painkillers and stomach ulcers.
• Kidney disease, or risk factors such as diabetes and dehydration. See our article on regular NSAID use and the kidneys.
• High blood pressure, heart failure or other heart disease. NSAIDs may raise blood pressure, can cause fluid retention, and can reduce the effect of some blood pressure medicines. See our article on ibuprofen with blood pressure medication. A review of OTC pain relievers in PubMed Central discusses heart and kidney safety for these drugs: Cardiorenal Safety of OTC Analgesics. Findings about differences between individual NSAIDs are mixed, so no single drug is risk free. Labels also warn against NSAID use around heart bypass surgery.
• Low-dose aspirin for the heart. Ibuprofen may interfere with the protective effect of low-dose aspirin, and product labeling for ibuprofen addresses this. Do not stop your aspirin on your own; ask your pharmacist or prescriber about timing or alternatives, especially if you have had a heart attack or stroke.
• Blood thinners, steroids, or other NSAIDs including aspirin. The combination can raise the chance of serious bleeding.
• Asthma that worsens with aspirin or NSAIDs. Some people react to the whole class.
• Pregnancy or trying to conceive. NSAID labels advise asking a health professional before use at any stage of pregnancy. Current label warnings also advise avoiding ibuprofen or naproxen from about 20 weeks of pregnancy onward unless a clinician specifically directs it, because use at that point can cause kidney problems in the baby and low amniotic fluid, and use late in pregnancy can affect a blood vessel in the baby's heart. Acetaminophen is often the first choice in pregnancy, but talk to your obstetric clinician before taking any pain reliever.
• Age 65 or older. Older adults can be more sensitive to stomach, kidney and blood pressure effects.

For children, follow the age directions on the product label and check with your pediatrician or pharmacist.

Taking either drug more safely

• Use the lowest amount on the label that controls your pain, for the shortest time.
• Take it with food or milk if it upsets your stomach.
• Use only one NSAID at a time, and check combination cold, flu and sinus products. Many contain an NSAID, so a second product can double up. MedlinePlus (NIH) explains these labels: Cold and Cough Medicines.
• Drink fluids, especially if you are sick with vomiting, diarrhea or a fever, because dehydration adds kidney strain.
• If you take a prescription NSAID, do not change the timing or amount on your own. Ask the prescriber.
• If you are weighing acetaminophen (Tylenol), see our articles on ibuprofen versus acetaminophen and on taking Tylenol and Advil together.
• Keep pills out of children's reach. If a child swallows any, or anyone takes more than intended, call Poison Control at 1-800-222-1222 right away. If the overdose was intentional, or you are having thoughts of harming yourself, call or text 988 (Suicide and Crisis Lifeline) as well.

Prescription NSAID labels carry a boxed warning about heart attack, stroke and stomach bleeding, and OTC labels carry related warnings in the Drug Facts panel. Read it, especially if you are older or have heart or stomach problems, and ask your pharmacist or prescriber if anything on it applies to you.

When a pain reliever is not the right tool

Pain that lasts more than a few weeks, keeps returning, or needs a pill every day is worth discussing with a clinician. MedlinePlus (NIH) describes chronic pain and its range of treatments: Chronic Pain. Many people also use non-drug approaches such as heat, gentle movement, physical therapy and stress reduction, often together with medicine: Non-Drug Pain Management.

Chest, abdominal and sudden severe pain are different problems and should not be treated as a routine ache. Pain in the chest can come from the heart, and an NSAID does not help that and may delay care. See our guides on chest pain and abdominal pain causes.
