The most widely used medicines for inflammation are NSAIDs, a group of drugs that includes ibuprofen, naproxen, and aspirin. These are available over the counter and work well for short-term flare-ups like a swollen joint, a pulled muscle, or menstrual cramps. For more serious or chronic inflammatory conditions, prescription options range from corticosteroids to targeted biologic drugs. Which one is right depends on what’s causing your inflammation and how long you’ve had it.
Over-the-Counter NSAIDs
NSAIDs (nonsteroidal anti-inflammatory drugs) are the first-line choice for everyday inflammation. They work by blocking enzymes called COX-1 and COX-2, which your body uses to produce chemicals that trigger swelling, pain, and fever. By slowing that production, NSAIDs reduce all three at once.
The most common OTC options are ibuprofen (Advil, Motrin) and naproxen (Aleve). For mild to moderate pain and swelling, a typical adult dose of ibuprofen is 400 mg every four to six hours as needed. For ongoing conditions like osteoarthritis, doctors sometimes recommend higher daily totals of 1,200 to 3,200 mg divided into three or four doses, though that range requires medical guidance. Naproxen lasts longer per dose, so you take it less frequently, which some people find more convenient.
Aspirin also qualifies as an NSAID, but it behaves differently. It irreversibly modifies the COX enzyme rather than just blocking it temporarily, which is why low-dose aspirin is used to prevent blood clots. At higher doses (above 325 mg per day), aspirin acts on the kidneys the same way other NSAIDs do and carries similar risks.
Why Acetaminophen Doesn’t Count
Acetaminophen (Tylenol) is often grouped with these drugs, but it does not treat inflammation. It can reduce pain and fever, but it only works in the central nervous system. NSAIDs work throughout the body, which is why they actually bring down swelling in a sore knee or an inflamed tendon. If inflammation is your specific problem, acetaminophen won’t address it.
Topical Anti-Inflammatory Gels
If you’d rather not take a pill, topical NSAID gels like diclofenac (Voltaren) deliver the drug directly to the tissue. These gels produce similar drug concentrations in the underlying muscle but much lower levels in the bloodstream compared to oral NSAIDs. That means fewer systemic side effects, particularly for the stomach and kidneys.
The tradeoff is effectiveness. In a randomized trial of patients with acute low back pain, oral ibuprofen outperformed topical diclofenac gel at the two-day mark. Adding the gel on top of oral ibuprofen didn’t provide any additional benefit. Topical NSAIDs tend to work best for localized problems close to the skin’s surface, like knee osteoarthritis or a sprained ankle, rather than deeper or more widespread inflammation.
Corticosteroids for Stronger Inflammation
When OTC options aren’t enough, corticosteroids are the next step up. These are prescription drugs that suppress the immune system’s inflammatory response more broadly than NSAIDs. They slow down your body’s production of the chemicals that drive swelling, and they do it fast. Common examples include prednisone, prednisolone, and dexamethasone, available as pills, injections, inhalers, or creams depending on where the inflammation is.
Doctors prescribe corticosteroids for a wide range of conditions: rheumatoid arthritis, lupus, asthma, eczema, vasculitis, severe allergic reactions, bursitis, and tendinitis, among others. A short course of a few days to a couple of weeks is generally well tolerated. Long-term use is where problems emerge. Extended steroid therapy can cause bone thinning, weight gain, mood changes, muscle weakness, and suppression of your adrenal glands, which normally produce your body’s own stress hormones. In children and teenagers, prolonged use can slow growth. If you’ve been on corticosteroids for more than a few weeks, stopping abruptly can be dangerous because your adrenal glands need time to resume normal function.
Biologic Drugs for Chronic Conditions
For autoimmune diseases that cause persistent, destructive inflammation, such as rheumatoid arthritis, psoriatic arthritis, or inflammatory bowel disease, biologics target specific proteins in the immune system. The most common class is TNF inhibitors. TNF-alpha is a signaling protein that tells your cells to activate inflammatory processes. When your immune system overproduces it, the result is chronic tissue damage. TNF inhibitors block that protein from binding to its receptors, interrupting the cycle.
These drugs are classified as biologic DMARDs (disease-modifying anti-rheumatic drugs), meaning they don’t just mask symptoms. They slow or stop the underlying disease process that’s destroying joints or organs. They’re more effective than older DMARDs and represent a major advance for people with conditions that don’t respond to standard treatment. Biologics are given by injection or infusion and require a prescription from a specialist, typically a rheumatologist or gastroenterologist.
Fish Oil and Curcumin Supplements
Fish oil is the supplement with the strongest evidence for anti-inflammatory effects. Regular supplementation has been shown to reduce resting heart rate, lower triglycerides, and raise HDL cholesterol, all markers tied to chronic low-grade inflammation. The omega-3 fatty acids in fish oil (EPA and DHA) work by competing with the same raw materials your body uses to make inflammatory compounds.
Curcumin, the active ingredient in turmeric, gets more attention but has weaker clinical support. In a 16-week placebo-controlled trial, curcumin supplementation did not significantly improve cardiovascular or cerebrovascular function markers, either alone or combined with fish oil. A handful of smaller trials have shown curcumin can improve blood vessel function in both younger and older adults, possibly by boosting the production of nitric oxide in blood vessel walls. But these results haven’t been consistent across studies. Both supplements are generally safe, with gastrointestinal discomfort being the most commonly reported side effect.
Risks of Long-Term NSAID Use
NSAIDs are effective, but they aren’t harmless when used regularly. They reduce blood flow to the kidneys, which can lead to acute kidney injury or worsen existing kidney disease, especially at higher doses. The National Kidney Foundation advises people with chronic kidney disease, particularly those with filtration rates below 60, to avoid NSAIDs entirely. The same applies to people with liver disease, heart failure, or high blood pressure, and to those taking blood pressure medications like ACE inhibitors or diuretics.
Stomach irritation, ulcers, and gastrointestinal bleeding are the other well-known risks. Taking NSAIDs with food or using a proton pump inhibitor alongside them can reduce, but not eliminate, that risk. For people who need long-term anti-inflammatory treatment, these side effects are a major reason doctors often move to other drug classes rather than keeping someone on daily ibuprofen or naproxen indefinitely.
Choosing the Right Option
For a short-term problem like a sports injury, dental pain, or a flare of joint stiffness, an OTC NSAID like ibuprofen or naproxen is the standard starting point. If your inflammation is localized and mild, a topical gel may be enough with fewer side effects. For inflammation driven by an autoimmune condition or one that keeps coming back, you’ll likely need prescription treatment, whether that’s a short course of corticosteroids to get things under control or a longer-term plan involving DMARDs or biologics. Fish oil is a reasonable daily supplement for general inflammatory tone but isn’t a substitute for medication when you have an active inflammatory condition.
