Ibuprofen vs. Naproxen: The Short Answer
Ibuprofen (Advil, Motrin) and naproxen (Aleve) are both nonsteroidal anti-inflammatory drugs, or NSAIDs. They relieve pain, reduce fever, and calm inflammation in the same way, and both are sold over the counter and in stronger prescription versions.
The biggest practical difference is how long they last. Ibuprofen wears off sooner and is taken more often through the day; naproxen lasts longer, so fewer doses cover the same stretch of time. Their risks for the stomach, kidneys, heart, and blood pressure are shared, and the person taking the pill matters more than the pill itself.
How NSAIDs Work
NSAIDs block enzymes called COX-1 and COX-2, which make prostaglandins, chemicals that drive pain, fever, and inflammation. The trouble is that prostaglandins also protect the stomach lining, keep blood flowing to the kidneys, and help regulate blood pressure. That trade-off explains nearly every NSAID side effect.
When Each One Fits
Ibuprofen
- Shorter, flexible relief for headaches, menstrual cramps, dental pain, or a sore muscle after yard work
- Easy to stop and start, since it clears the body more quickly
- Lower over-the-counter doses are generally considered among the gentler NSAID options for the stomach
Naproxen
- Longer-lasting relief for pain that persists through the day or night, such as a sprain or an arthritis flare
- Fewer doses to remember
- Longer exposure per dose, which matters for people at risk for stomach or kidney problems
For osteoarthritis of the knee or hand, a topical NSAID such as diclofenac gel delivers relief to the joint with much less of the drug reaching the bloodstream, which makes it a smart first choice for many older adults. Our guide to non-surgical knee arthritis treatment covers other options.
Over-the-Counter vs. Prescription Strength
Prescription ibuprofen and naproxen are the same medicines as the store-brand versions, in higher strengths. That means a prescription carries the same risks as the bottle in your cabinet, only more of them, and the two should never be combined. Aleve contains naproxen sodium, a salt form that is absorbed a little faster than plain naproxen, the form often prescribed.
Children and teens
Ibuprofen is widely used in children with weight-based dosing, and pediatric liquid forms are common. Over-the-counter naproxen is labeled for ages 12 and older unless a doctor directs otherwise. For any child, follow the package directions or your pediatrician's advice rather than splitting adult tablets.
Combination products
Many cold, flu, sinus, and nighttime sleep products contain ibuprofen or naproxen alongside other ingredients. Taking one of these on top of your usual pain reliever is a common way people double up without realizing it, so read the active ingredients on every label.
Risks They Share
Stomach and bleeding
NSAIDs can cause ulcers and bleeding, sometimes without warning pain. Risk rises with age over 60, a past ulcer or peptic ulcer disease, blood thinners, steroids, regular alcohol use, and higher doses or longer use.
Kidneys
NSAIDs reduce blood flow to the kidneys. That matters most in people with chronic kidney disease, heart failure, or dehydration, and in those taking blood pressure medicines such as ACE inhibitors or ARBs together with a diuretic.
Heart and blood pressure
All non-aspirin NSAIDs carry an FDA boxed warning for increased risk of heart attack and stroke, which can begin within the first weeks of use and rises with dose. They can also raise blood pressure and cause fluid retention. Some studies suggest naproxen may carry less heart risk than other NSAIDs, but FDA has said the evidence is not strong enough to call any NSAID safe for the heart.
The MedlinePlus pages for ibuprofen and naproxen list the full warnings.
Who Should Avoid Both
- People taking blood thinners such as warfarin, apixaban, or rivaroxaban, unless a doctor approves
- People with kidney disease, heart failure, or a history of stomach bleeding
- Pregnancy at 20 weeks or later. The FDA advises avoiding NSAIDs from 20 weeks of pregnancy because they can cause low amniotic fluid; ask before using them at any point in pregnancy.
- Anyone with an aspirin or NSAID allergy, including asthma triggered by these drugs
The aspirin problem
If you take a daily low-dose aspirin for your heart, ibuprofen can interfere with aspirin's protective effect when the two are taken close together, and naproxen may as well. Ask us how to time them, or whether a different pain reliever makes more sense.
Safer Habits With Any NSAID
- Use the lowest dose for the shortest time. Over-the-counter labels say not to use them for pain longer than 10 days without talking to a doctor.
- Never combine NSAIDs, such as ibuprofen with naproxen, and check cold and flu products, which often contain one.
- Take them with food to ease stomach upset.
- Stay hydrated, especially during St. Petersburg summers, when heat and sweating already strain the kidneys.
- Consider acetaminophen first for many types of pain, especially in older adults, staying within the daily limit on the label.

When to See Your Doctor
- Needing an NSAID for more than 10 days, or most days of the week
- Black, tarry stools, vomiting blood, or stomach pain that wakes you at night (seek care promptly)
- Swelling in the legs, sudden weight gain, or shortness of breath
- Much less urine than usual, especially after heat exposure or illness
- Chest pain, weakness on one side, or trouble speaking (call 911)
- Higher home blood pressure readings since starting a pain reliever
