The most widely used medicines for inflammation are NSAIDs (nonsteroidal anti-inflammatory drugs), available both over the counter and by prescription. Ibuprofen, naproxen, and aspirin are the most common starting points, but the right choice depends on whether your inflammation is short-term or chronic, where it is in your body, and what other health conditions you have.
How Anti-Inflammatory Medicines Work
Your body produces compounds called prostaglandins whenever tissue is damaged or irritated. Prostaglandins trigger the hallmarks of inflammation: swelling, redness, heat, and pain. NSAIDs work by blocking the enzyme that converts a fatty acid in your cells into prostaglandins. There are two versions of this enzyme. The first handles everyday functions like protecting your stomach lining and supporting kidney blood flow. The second ramps up specifically during injury and inflammation. Most over-the-counter NSAIDs block both versions, which is why they reduce inflammation effectively but can also cause stomach and kidney side effects with prolonged use.
Over-the-Counter Options
Three NSAIDs dominate the drugstore shelf, and each has a slightly different profile:
- Ibuprofen (Advil, Motrin): 200 mg tablets, one to two every four to six hours. Maximum 1,200 mg per day for self-treating adults. It works quickly and is a solid choice for muscle pain, joint soreness, menstrual cramps, and general aches.
- Naproxen sodium (Aleve): 220 mg tablets, one to two every eight to twelve hours. Maximum 660 mg per day. It lasts longer per dose than ibuprofen, so you take it less often.
- Aspirin: 325 mg tablets, one to two every four hours or three every six hours. Maximum 4,000 mg per day. Aspirin also thins the blood, which makes it useful for heart protection but less ideal if you bruise easily or are preparing for surgery.
For short-term inflammation from a sprain, dental procedure, or flare of joint pain, any of these three can help. Naproxen’s longer duration makes it convenient when you need all-day relief. Ibuprofen’s faster onset is useful when you want relief within 30 minutes.
Acetaminophen Is Not an Anti-Inflammatory
A common point of confusion: acetaminophen (Tylenol) relieves pain and reduces fever, but it does not reduce inflammation. It appears to work on a different version of the same enzyme pathway, one that affects pain signaling in the brain but doesn’t meaningfully lower swelling in your joints or muscles. If inflammation is specifically what you’re treating, acetaminophen won’t address the underlying problem. It can still help with pain, and it’s easier on the stomach, so some people combine it with an NSAID under their doctor’s guidance.
Topical Anti-Inflammatories
If your inflammation is in a specific joint, especially a knee, hand, or elbow close to the skin surface, topical formulations deliver the drug directly where you need it. Topical diclofenac (Voltaren gel, available without a prescription) has been shown to significantly improve pain, stiffness, and physical function in knee osteoarthritis compared to placebo, with only minor skin irritation and no significant systemic side effects. This makes it a strong option if you want to avoid the stomach and kidney risks that come with swallowing an anti-inflammatory pill every day.
Prescription-Strength Options
When over-the-counter doses aren’t enough, doctors can prescribe higher-strength NSAIDs or different formulations. Prescription diclofenac, meloxicam, and indomethacin are common choices. Celecoxib is a prescription NSAID designed to target only the inflammation-specific enzyme, which reduces (though doesn’t eliminate) the risk of stomach ulcers compared to traditional NSAIDs.
Corticosteroids
For more intense or widespread inflammation, corticosteroids like prednisone, methylprednisolone, and dexamethasone are powerful anti-inflammatory agents. They suppress the immune response broadly, which makes them effective for asthma flares, allergic reactions, inflammatory bowel disease episodes, and autoimmune conditions. Doctors prescribe them as short courses (a “burst” of a few days to two weeks) when possible, because long-term corticosteroid use carries real consequences. Bone loss is a major concern: studies have found bone damage in 9% to 40% of patients on long-term steroid therapy. Weight gain, elevated blood sugar, and thinning skin are also common with extended use. Oral corticosteroids are generally reserved for situations where NSAIDs aren’t enough.
Disease-Modifying Drugs for Chronic Inflammation
Conditions like rheumatoid arthritis, psoriatic arthritis, lupus, and inflammatory bowel disease involve inflammation that doesn’t just cause pain; it progressively damages tissue. For these, doctors use a category of drugs that go beyond symptom relief and actually slow the disease process. Methotrexate is the most commonly prescribed starting point for rheumatoid arthritis. Other options in this class include sulfasalazine, leflunomide, and hydroxychloroquine.
When those aren’t sufficient, biologic drugs target specific molecules in the immune system that drive inflammation. Some block a protein called TNF-alpha, a key inflammation trigger. Others target different immune signaling molecules. These are typically given as injections or infusions and are used for moderate to severe autoimmune and inflammatory diseases. A newer class of oral drugs works by interrupting immune signaling inside cells, offering a pill-based alternative to injections for some patients.
Supplements With Anti-Inflammatory Evidence
Two supplements have the most research behind them for inflammation: turmeric (specifically its active compound curcumin) and omega-3 fatty acids from fish oil. Curcumin blocks a key inflammatory pathway in cells and has been shown in lab studies to reduce the release of enzymes that break down cartilage. Clinical trials have demonstrated some benefit, particularly for joint-related inflammation. The challenge with curcumin is absorption: your body doesn’t absorb it well on its own, so formulations designed for better absorption tend to work better than plain turmeric powder.
Omega-3 fatty acids, particularly from fish oil, reduce inflammatory markers in animal studies and have shown some benefit for joint pain in humans. The evidence for omega-3s is less consistent than for curcumin in clinical trials, but they carry few side effects and offer additional cardiovascular benefits. Neither supplement works as fast or as powerfully as an NSAID, but both may help as part of a longer-term strategy for managing low-grade or chronic inflammation.
Risks of Long-Term NSAID Use
NSAIDs are safe for most people when used occasionally, but the risks rise significantly with daily use over weeks or months. Minor digestive side effects like nausea, stomach pain, and diarrhea affect 10% to 60% of regular users. More concerning, endoscopic studies show that 20% to 30% of people taking NSAIDs regularly develop stomach ulcers, even if they don’t feel symptoms. Among those who take NSAIDs for a full year, 2% to 4% develop symptomatic ulcers or serious complications like gastrointestinal bleeding. In high-risk patients, the rate of serious complications climbs to roughly 10% per year.
Kidney problems are the other major risk. Healthy younger adults rarely have issues, but if you have heart failure, liver disease, chronic kidney disease, or low blood volume, NSAIDs can trigger acute kidney failure by reducing blood flow to the kidneys. Taking NSAIDs alongside blood pressure medications or diuretics further increases this risk. NSAIDs can also raise blood pressure or worsen existing hypertension by causing your body to retain sodium and fluid, particularly in older adults.
Choosing the Right Approach
For a sore knee after a weekend hike or a stiff back after yard work, an over-the-counter NSAID taken for a few days is a straightforward and effective choice. If the inflammation is in a joint you can reach with your hands, topical diclofenac gives you anti-inflammatory relief with minimal whole-body exposure. For inflammation that keeps coming back or lasts more than a couple of weeks, the cause matters more than the painkiller you choose. Recurring joint inflammation, persistent swelling, or inflammation that moves between different parts of your body warrants a medical evaluation, because treating only the symptom can mask a condition that benefits from earlier, more targeted therapy.
