Millions of Americans have arthritis and other painful health problems affecting the musculoskeletal system: the joints, muscles and bones. A mainstay of treatment for these conditions for more than three decades has been a class of medications known as nonsteroidal anti-inflammatory drugs or NSAIDs.
Traditional NSAIDs include aspirin, ibuprofen (Advil, Motrin, etc.), naproxen (e.g., Aleve) and many other generic and brand name drugs. A newer NSAID is celecoxib (Celebrex), which doctors call a "COX-2 inhibitor" or a "COX-2 selective" NSAID.


  • Nonsteroidal anti-inflammatory drugs are some of the most often used pain medicines in adults.
  • NSAIDs also can decrease inflammation, such as in arthritis.
  • Most people can take NSAIDs without any trouble. Yet side effects are possible, including stomach bleeding, allergic reactions, kidney problems and heart problems.
  • Though you can buy many NSAIDs without a doctor's prescription, not everyone should take these drugs. Always talk to your doctor before taking any new medicine.


NSAIDs are used to relieve pain and reduce signs of inflammation: fever, swelling and redness. People may take NSAIDs for temporary conditions such as sprains, strains, flares of back pain, headache and painful menstrual periods. NSAIDs also are a common treatment for chronic (long-term) health problems such as arthritis (rheumatoid arthritis, osteoarthritis and others) and lupus.
Another use of aspirin is for prevention. A daily low-dose aspirin can help lower the chance of having a heart attack or stroke for people who are at high risk of these serious events.


NSAIDs work to decrease inflammation, pain and fever. NSAIDs block enzymes in the body that help make prostaglandins, chemicals that play a role in pain and inflammation. Older NSAIDs like ibuprofen block two of these enzymes, COX-1 and COX-2, but celecoxib (Celebrex) targets mainly COX-2. Celecoxib is no more effective than other NSAIDs. However, its possible risks differ from those of other NSAIDs, as the “Side effects” section below explains.


Each NSAID has its own dose (strength) and interval for how often to take the drug. The doses of medicines that are over the counter—sold without a doctor's prescription—are often less than prescription doses of the same medicine. For instance, the most common doses of prescription ibuprofen are 400 mg (which stands for milligrams), 600 mg and 800 mg, but the highest dose sold over the counter is 200 mg.
Over-the-counter NSAIDs may be strong enough for temporary conditions such as sprains, strains, flares of back pain, headache and menstrual pain. For chronic health problems such as arthritis or lupus, a rheumatologist will most often prescribe these drugs at higher doses and over a long time.
Ask your doctor to explain the goal of using an NSAID for your condition. If the goal of taking the NSAID is to suppress inflammation, you likely will need to take higher doses and at a set dosing interval. If it is mainly to relieve pain, you can often take lower doses on an as-needed basis.


NSAIDs start to work quickly, most often in less than a few hours. How fast they take effect depends on the intended effect. Pain control tends to occur much quicker than anti-inflammatory (inflammation-fighting) effects, such as for arthritis.


All drugs have a risk of side effects, including NSAIDs. It is important to understand the risks and benefits of a drug before deciding to take it. Possible risks of all NSAIDs include, among others:
  • Stomach problems like bleeding, ulcer and stomach upset
  • High blood pressure
  • Fluid retention (causing swelling, such as around the lower legs, feet, ankles and hands)
  • Kidney problems
  • Heart problems
  • Rashes

Many people may assume that over-the-counter medications are safer than the same or similar medicines that need a prescription, but this is not always true. Medications must be generally safe before the FDA will allow them on the market. For added safety, the doses of over-the-counter medicines are often less than prescription doses of the same medicine. In equal doses, the safety profile of over-the-counter NSAIDs is the same as for their prescription forms. The risk of side effects does go up with higher doses.
Though side effects can occur at any time you take an NSAID, the chance tends to be greater the longer you take the drug. If you must take NSAIDs for more than 30 days, ask your doctor how to lower your risk of problems. You may need to take extra precautions to avoid side effects, such as taking medicine to lower the risk of stomach bleeding.
There is no clear difference in overall safety among traditional NSAIDs on the market. Side effects of each drug may vary, and some patients may be more prone to the side effects of one drug than another. In some studies, naproxen appears safer on the heart. Celecoxib is somewhat less likely to cause stomach problems, such as ulcers and bleeding, than traditional NSAIDs. Yet some large studies in patients have linked celecoxib to a possible raised risk of heart problems, more so at doses above 200 mg per day.
Warnings: If you have heart disease, you should not take celecoxib or another NSAID, including an over-the-counter NSAID, without first discussing it with your doctor. Treatments such as acetaminophen (Tylenol) or other pain medicine may be better in this case. Some traditional NSAIDs may also interfere with aspirin prescribed to patients with heart disease. As well, mixing aspirin with other NSAIDs raises the risk of stomach bleeding.
NSAIDS should not be used during pregnancy unless your doctor thinks they are necessary.
Some people have other risk factors that raise their chance of having health problems due to NSAIDs. Talk to your doctor before taking an NSAID if any of these risk factors apply to you:
  • Have any of these health problems
    • decreased kidney or liver function, or an uncontrolled liver problem (such as hepatitis)
    • ulcer, gastritis (inflammation of the stomach lining) or stomach bleeding now or in the past
    • low platelet count
    • Crohn's disease or ulcerative colitis
    • asthma or chronic lung disease
    • reflux disease (also known as GERD), indigestion or hiatal hernia
    • high blood pressure, congestive heart failure or a past stroke or heart attack

  • Are allergic to aspirin, other NSAIDs, or sulfa drugs, or have nasal polyps (linked to a greater chance of NSAID allergy)
  • Take blood thinners or corticosteroids (see “Drug interactions” below)
  • Are pregnant, may become pregnant, or are breast-feeding
  • Drink more than seven alcoholic drinks per week or more than two in a day
  • Age over 65

Doctors have long warned not to give aspirin to children under age 12, but teens with a virus also should avoid drugs containing aspirin. There is a risk of Reye’s syndrome, a rare but deadly illness that can affect the brain and liver.


Tell your doctor about all of the medications you are taking, even ones that are over the counter or natural remedies. Some medicines increase the risk of side effects of NSAIDs. These include aspirin and other blood thinners like warfarin (Coumadin), heparin and clopidogrel (Plavix) as well as corticosteroids, such as prednisone. If you take any of these medicines, ask your doctor if you can take NSAIDs.
Do not mix an over-the-counter NSAID with a prescribed NSAID, or take more than the recommended dose of the NSAID. Doing so could increase your chance of side effects.


Tell your other doctors that you are taking an NSAID. This will help avoid drug interactions.
To help decide the safest and best possible treatment for your arthritis or other health problem, your rheumatologist will want to know if you have, or in the past had, any of the risk factors listed above that raise the chance of having side effects due to NSAIDs. Women should mention if they are pregnant, as NSAIDs may be risky during pregnancy. Besides a complete health history, your doctor will want a list of all the medications you are taking or have taken recently, including store-bought ones.
Though very effective for relieving pain and inflammation, NSAIDs are not the best choice for all people. The choice of an NSAID or other drug will depend on many factors. If NSAIDs are not right for you, there are many other drug choices your rheumatologist may suggest for you. Besides medicines, other treatments sometimes can help decrease pain. These include corticosteroid injections (shots) into the affected site, physical therapy, use of heat or cold, massage and relaxation therapies, and acupuncture.
For most people with arthritis, being physically active, eating right and keeping a healthy weight are good ways to ease arthritis pain. The fact sheets “Exercise and Arthritis” and “Living Well with a Rheumatic Disease” describe a healthy lifestyle.


  • NSAIDs can be very effective medications for people with arthritis or other rheumatic diseases.
  • At low doses, NSAIDs work as painkillers. To reduce inflammation, higher doses are needed.
  • No one NSAID is better or safer overall than any other NSAID.
  • Ask your physician whether you can take NSAIDs if you are pregnant, taking other medicines, over age 65 or under a doctor’s care for a health problem.
  • Do not take an over-the-counter NSAID if you are taking a prescription NSAID.
  • Tell your doctor if you have any problems taking NSAIDs.
