Anti-inflammatory medications fall into three main categories: NSAIDs (like ibuprofen and naproxen), corticosteroids (like prednisone and hydrocortisone), and biologic drugs used for chronic autoimmune conditions. Which type is right depends on what’s causing the inflammation, how severe it is, and how long you need treatment.
One important distinction upfront: acetaminophen (Tylenol) is not an anti-inflammatory. It reduces pain and fever, but it does nothing to reduce inflammation itself. If swelling is part of your problem, acetaminophen won’t address it.
NSAIDs: The Most Common Anti-Inflammatories
Nonsteroidal anti-inflammatory drugs, or NSAIDs, are the first option most people reach for. They work by blocking enzymes in your body that produce chemicals responsible for inflammation, pain, and fever. This makes them useful for a wide range of everyday problems: muscle aches, back pain, arthritis, tendonitis, bursitis, toothaches, and menstrual cramps.
The three you can buy without a prescription are:
- Ibuprofen (Advil, Motrin)
- Naproxen sodium (Aleve)
- Aspirin (Bayer)
Prescription-strength NSAIDs include celecoxib (Celebrex), diclofenac (Voltaren), indomethacin (Indocin), and ketorolac (Toradol), among others. Celecoxib belongs to a subclass called COX-2 inhibitors, which target inflammation more selectively and tend to be easier on the stomach than traditional NSAIDs.
NSAIDs come in tablets, capsules, liquids, topical gels and creams, and even suppositories. Topical versions like diclofenac gel deliver the drug directly to a sore joint or muscle, which limits how much enters your bloodstream and reduces the risk of side effects elsewhere in the body.
How Quickly NSAIDs Work
Most oral NSAIDs start providing noticeable pain relief within one to two hours. Some work faster: ketorolac, a prescription NSAID often used for acute pain, can show measurable relief within 20 minutes of the first dose. In clinical studies, patients taking various NSAIDs typically reached a 30% reduction in pain intensity within about 27 to 33 minutes.
That said, the full anti-inflammatory effect takes longer to build. If you’re using an NSAID for something like arthritis or tendonitis, you may need to take it consistently for several days before you notice a meaningful reduction in swelling and stiffness.
NSAID Risks Worth Knowing
NSAIDs are effective, but they carry real risks when used at high doses or over long periods. The two biggest concerns are stomach damage and cardiovascular problems.
On the stomach side, all NSAIDs can irritate the lining of your digestive tract, potentially causing ulcers or bleeding. Among over-the-counter options, low-dose ibuprofen carries the lowest gastrointestinal risk. COX-2 inhibitors like celecoxib also cause fewer stomach problems than most traditional NSAIDs at equivalent doses. Piroxicam, ketoprofen, and ketorolac sit at the higher end of gastrointestinal risk.
On the cardiovascular side, the picture varies by drug. Naproxen at standard doses (up to 1000 mg daily) does not appear to increase the risk of heart attack based on large-scale data, making it a reasonable choice for people with cardiovascular concerns. Ibuprofen at lower doses (1200 mg daily or less) also shows no increased heart attack risk, but at higher doses a small risk may emerge. Diclofenac at 150 mg daily carries a clot-related risk comparable to COX-2 inhibitors, which is why it’s generally not recommended for people with existing heart disease.
NSAIDs can also strain the kidneys, particularly in people who are dehydrated, older, or already have reduced kidney function.
Corticosteroids: Stronger and Broader
When NSAIDs aren’t enough, corticosteroids are the next step up. These are synthetic versions of cortisol, a hormone your body naturally produces to regulate inflammation. Corticosteroids suppress the immune response more broadly than NSAIDs, which makes them powerful but also means they come with more side effects when used long-term.
Corticosteroids come in two main forms. Systemic corticosteroids, taken as pills or given by injection, treat widespread inflammation. Prednisone and methylprednisolone are the most commonly prescribed oral versions. These are used for flares of asthma, lupus, inflammatory bowel disease, severe allergic reactions, and many other conditions. They work quickly, often within hours, but doctors typically prescribe them for the shortest time possible because prolonged use can lead to weight gain, bone thinning, blood sugar problems, and a weakened immune system.
Topical corticosteroids treat inflammation on the skin. They’re ranked by potency from class VII (mildest) to class I (strongest). Hydrocortisone 1%, available over the counter, is one of the mildest. Prescription options like triamcinolone and betamethasone are progressively stronger, and the most potent versions (clobetasol, halobetasol) are reserved for stubborn conditions like thick psoriasis plaques. Stronger topical steroids work better, but they also carry greater risk of thinning the skin, especially on delicate areas like the face or skin folds. They come as ointments, creams, lotions, gels, foams, and even medicated tape.
Biologic Drugs for Chronic Inflammation
For autoimmune and autoinflammatory diseases where the immune system itself is the problem, a newer class of drugs called biologics targets specific proteins driving the inflammation. The most established group is TNF inhibitors, which block a protein called tumor necrosis factor alpha. Normally, this protein triggers inflammatory processes when it binds to receptors on your cells. TNF inhibitors prevent that binding, which dials down chronic inflammation at its source.
FDA-approved TNF inhibitors include adalimumab (Humira), etanercept (Enbrel), infliximab (Remicade), certolizumab pegol (Cimzia), and golimumab (Simponi). These are classified as disease-modifying anti-rheumatic drugs, or DMARDs, because they don’t just manage symptoms. They slow the actual disease process that damages joints, skin, and organs.
TNF inhibitors are approved for a wide range of conditions: rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, plaque psoriasis, Crohn’s disease, ulcerative colitis, and certain types of eye inflammation, among others. They’re given as injections or infusions, typically on a schedule ranging from every week to every several weeks depending on the drug. Because they suppress part of the immune system, they increase susceptibility to infections, so regular monitoring is part of the treatment.
Biologics aren’t first-line treatments. You’ll typically try NSAIDs or conventional DMARDs like methotrexate before moving to a biologic. But for people with moderate to severe autoimmune inflammation that hasn’t responded to other options, they can be transformative.
Choosing the Right Option
For short-term pain with swelling, such as a sprained ankle, sore back, or post-workout soreness, an over-the-counter NSAID like ibuprofen or naproxen is usually the simplest and most effective choice. Naproxen lasts longer per dose (you take it every 8 to 12 hours versus every 4 to 6 for ibuprofen), which makes it more convenient for sustained pain. Ibuprofen offers slightly more flexibility to take smaller, less frequent doses when you need less coverage.
For localized joint or muscle inflammation, a topical NSAID or topical corticosteroid lets you treat the area directly without exposing your whole body to the drug. For skin conditions like eczema or psoriasis, topical corticosteroids are the standard treatment, with potency matched to the severity and location of the rash.
For chronic inflammatory diseases like rheumatoid arthritis or Crohn’s disease, treatment usually involves a combination approach: NSAIDs for immediate symptom relief, corticosteroids for flares, and DMARDs or biologics to control the underlying disease over time.
