Anti-inflammatory medicines fall into three main categories: NSAIDs (like ibuprofen and naproxen), corticosteroids (like prednisone), and biologic drugs used for autoimmune conditions. The most widely used are NSAIDs, available over the counter at any pharmacy. Which type is right depends on what’s causing the inflammation and how long you need relief.
NSAIDs: The Most Common Anti-Inflammatories
Nonsteroidal anti-inflammatory drugs, or NSAIDs, are the go-to option for everyday pain and swelling. They work by blocking enzymes called COX-1 and COX-2 that your body uses to produce prostaglandins, the chemicals responsible for inflammation, pain, and fever. By cutting off that production, NSAIDs reduce swelling and make you more comfortable.
The most familiar over-the-counter options are ibuprofen (sold as Advil or Motrin) and naproxen (sold as Aleve). Ibuprofen is typically taken every six to eight hours, while naproxen lasts longer and is usually taken twice a day. Aspirin also qualifies as an NSAID, though at lower doses (75 to 325 mg) it primarily acts as a blood thinner rather than an anti-inflammatory. Anti-inflammatory doses of aspirin are much higher, around 3,900 mg per day, which carries a significant risk of stomach problems.
Beyond the drugstore shelf, there are more than a dozen prescription-strength NSAIDs. Diclofenac, meloxicam, indomethacin, and ketorolac are among the most commonly prescribed. There’s also a subclass called COX-2 selective inhibitors, with celecoxib (Celebrex) being the primary one still on the market. COX-2 inhibitors target only one of the two inflammation-related enzymes, which tends to cause fewer stomach issues than traditional NSAIDs.
Topical Anti-Inflammatories
If you want to avoid swallowing a pill, topical NSAIDs deliver the drug directly through the skin. Diclofenac gel (sold as Voltaren) is the most common option and is now available over the counter. You rub it directly onto a sore joint or muscle, and it reduces inflammation in that specific area with far less drug entering your bloodstream.
The tradeoff is potency. A randomized study of patients with acute low back pain found that oral ibuprofen improved pain scores by about 10 points on a standardized scale after two days, while topical diclofenac improved scores by about 6.4 points. For localized joint pain like a sore knee, topical options often work well enough. For deeper or more widespread inflammation, oral NSAIDs tend to be more effective.
Corticosteroids: Stronger Prescription Options
When NSAIDs aren’t enough, corticosteroids are a more powerful class of anti-inflammatory. These are synthetic versions of cortisol, a hormone your body naturally produces. They suppress inflammation broadly by dialing down your immune system’s activity. Common names include prednisone, cortisone, hydrocortisone, and methylprednisolone.
Corticosteroids come in many forms: pills, injections into a joint, inhalers for asthma, and creams for skin conditions like eczema. Doctors use them for a wide range of inflammatory conditions, including rheumatoid arthritis, lupus, severe allergic reactions, asthma flares, bursitis, and tendinitis. They’re highly effective but aren’t meant for long-term daily use. Extended courses can lead to weight gain, bone thinning, elevated blood sugar, and a weakened immune system, so they’re typically prescribed at the lowest effective dose for the shortest time needed.
Biologic Drugs for Autoimmune Inflammation
For chronic autoimmune conditions where the immune system constantly drives inflammation, a newer class of drugs called biologics can target specific parts of the inflammatory process. TNF blockers are the best-known type. They work by blocking tumor necrosis factor, a protein that triggers inflammation in conditions like rheumatoid arthritis, Crohn’s disease, ulcerative colitis, and psoriasis.
The major TNF blockers include adalimumab (Humira), etanercept (Enbrel), infliximab (Remicade), certolizumab (Cimzia), and golimumab (Simponi). These are given by injection or infusion and require a prescription from a specialist. They’re not used for typical aches and pains. They’re reserved for people whose inflammatory disease hasn’t responded to standard treatments, because suppressing the immune system this precisely comes with an increased risk of infections.
Natural Anti-Inflammatories
Turmeric (specifically its active compound, curcumin) is the most studied natural anti-inflammatory. In a clinical trial of 107 patients with knee osteoarthritis, curcumin extract taken four times daily performed comparably to ibuprofen taken twice daily over six weeks. Pain scores during walking dropped from 5.3 to 2.7 in the curcumin group and from 5.0 to 3.1 in the ibuprofen group. Curcumin actually outperformed ibuprofen for pain during stair climbing. Stomach upset rates were similar between the two groups, around 21% for curcumin and 27% for ibuprofen.
The catch with curcumin is compliance. Patients in the study had to take it four times a day, and only about 83% stuck with the regimen compared to 90% of the ibuprofen group. Ginger, omega-3 fatty acids from fish oil, and boswellia are other natural options with some evidence of anti-inflammatory effects, though the research is less robust than for curcumin.
Risks of Anti-Inflammatory Medicines
NSAIDs are safe for occasional use, but daily use introduces real risks. The FDA warns that NSAIDs can increase the risk of heart attack and stroke, and this applies to people with and without existing heart disease. Serious cardiovascular side effects can appear as early as the first few weeks of daily use, and the risk climbs the longer you take them. If you also take low-dose aspirin for heart protection, some NSAIDs can interfere with aspirin’s ability to prevent clotting.
Kidney damage is another concern. NSAIDs reduce blood flow to the kidneys, which can raise blood pressure and cause kidney injury, especially at high doses or with long-term use. The National Kidney Foundation specifically warns people with chronic kidney disease to avoid ibuprofen, naproxen, and high-dose aspirin. Stomach ulcers and bleeding are the other major risk, particularly for older adults or anyone taking blood thinners.
The safest approach with any NSAID is the smallest dose that works, for the shortest time you need it. For people who need long-term anti-inflammatory treatment, corticosteroids or biologics under medical supervision are often a better fit than daily over-the-counter NSAIDs.
