NSAIDS, Non-Steroidal Anti-Inflammatory Drugs
NSAIDs, or non-steroidal anti-inflammatory drugs, are some of the oldest and most widely used medications for pain and inflammation. They may be used as a first-line treatment to help relieve the symptoms of ankylosing spondylitis (AS).1 In addition to AS, NSAIDs are used for a variety of conditions such as headaches, muscle aches, and other arthritis conditions.
Many NSAIDs are readily available over-the-counter, and as such, don’t need a prescription. However, higher strength NSAIDs that may be needed to help relieve pain and inflammation of AS are only available with a prescription. Higher doses and long-term use of NSAIDs may cause side effects, including side effects which may cause stomach or intestinal issues. Although NSAIDs are very effective for relieving pain and inflammation, they are not the best choice for all people.1
NSAIDs start to work quickly on pain, within a few hours of taking the medicine. The anti-inflammatory effects of NSAIDs take longer to realize.2 People with AS may have to try more than one NSAID to find relief from their symptoms. Treatment guidelines suggest daily use for most patients, although each individual should discuss with their doctor what is best for them. If NSAIDs fail to relieve symptoms, other treatments like TNF (tumor necrosis factor) inhibitors may be used.3
NSAIDs available over-the-counter include:
- Aspirin (available as Bayer®, Bufferin®, Ecotrin®, Excedrin®)
- Ibuprofen (available as Advil®, Motrin IB®, Nuprin®)
- Naproxen (available as Aleve® and Naprosyn®)
NSAIDs available by prescription for AS include:
- Voltaren (diclofenac)
- Celebrex® (celecoxib)
- Indocin (indomethacin)
- Mobic (meloxicam)
- Arthrotec (diclofenac and misoprostol)
How do NSAIDs work?
NSAIDs decrease inflammation, pain, and fever. Some NSAIDs, like ibuprofen, block two enzymes, COX-1 and COX-2. Celebrex and Mobic, prescription NSAIDs, target COX-2 and are also known as a COX-2 inhibitors. COX-2’s generally do not cause as many gastrointestinal side effects. Different NSAIDs may have similar effectiveness, but some people respond better to one NSAID than another. 2,4
What are the possible side effects of NSAIDs?
NSAIDs can cause unwanted side effects. Possible side effects of NSAIDs are stomach ulcers, stomach upset, high blood pressure, fluid retention (causing swelling around the lower legs, feet, ankles, and hands), kidney problems, heart problems, and rashes. Long-term use of NSAIDs has been associated with a slightly higher incidence of heart attacks and strokes. Although side effects can occur at any time, the risk of side effects increases with higher dosages and with a longer duration of treatment. Patients should discuss the risks and benefits with their doctor, as well as any additional precautions to avoid side effects.2,4 These are not all the possible side effects of NSAIDS. Patients should talk to their doctor about what to expect with treatment with NSAIDS.
