Oral nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen are the strongest-recommended over-the-counter medications for arthritis pain, according to the American College of Rheumatology. Topical NSAID gels and patches earn similarly high marks for knee arthritis with fewer side effects. But “best” depends heavily on which joints hurt, what other medications you take, and how your stomach, kidneys, and heart are holding up. The choice is rarely as simple as grabbing whatever is cheapest off the shelf.
Why NSAIDs Come Out on Top
The 2019 American College of Rheumatology/Arthritis Foundation guidelines give oral NSAIDs a “strong” recommendation for osteoarthritis of the hand, hip, and knee. That is the highest endorsement the panel uses, and oral NSAIDs share it with only a handful of non-drug approaches like exercise and weight loss.1PubMed Central. 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee Expert consensus panels have also positioned NSAIDs as first-line pharmacological therapy for osteoarthritis pain.2PubMed Central. Management of Osteoarthritis: Expert Opinion on NSAIDs
The two most widely available OTC oral NSAIDs are ibuprofen (sold as Advil, Motrin, and generics) and naproxen (sold as Aleve and generics). Both reduce pain, stiffness, and swelling. In a direct comparison among people with osteoarthritis, naproxen outperformed ibuprofen on resting pain, movement pain, night pain, and how much the disease interfered with daily activities.3PubMed. A study of naproxen and ibuprofen in patients with osteoarthritis seen in general practice That said, both drugs work, and both are meaningfully better than acetaminophen for most arthritis pain.
One reason NSAIDs earn the top spot is that they address inflammation directly. Arthritis pain is not just about the brain registering damage; much of it comes from inflammatory chemicals in and around the joint. Acetaminophen can dull pain signals, but it does not calm inflammation. NSAIDs do both, which matters when you are dealing with swollen, stiff joints.
Where Acetaminophen Fits In
Acetaminophen (Tylenol) gets a “conditional” recommendation in the same ACR guidelines, a step below the strong recommendation for NSAIDs.4PubMed Central. 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee – Section: RESULTS It used to be considered the obvious first choice because of its gentler side-effect profile, but newer evidence has eroded that standing.
An older trial found that short-term acetaminophen relieved knee osteoarthritis pain about as well as ibuprofen.5PubMed. Comparison of an antiinflammatory dose of ibuprofen, an analgesic dose of ibuprofen, and acetaminophen in the treatment of patients with osteoarthritis of the knee But when researchers pooled data from multiple trials, the picture changed: NSAIDs consistently beat acetaminophen for both resting pain and walking pain, with the advantage being small but real.6PubMed. A comparison of the efficacy and safety of nonsteroidal antiinflammatory agents versus acetaminophen in the treatment of osteoarthritis: a meta-analysis A separate systematic review confirmed the finding, describing the NSAID advantage as a small but statistically significant effect.7The Journal of Rheumatology. Nonsteroidal antiinflammatory drugs or acetaminophen for osteoarthritis of the hip or knee? A systematic review of evidence and guidelines
Acetaminophen is not useless. If you cannot take NSAIDs because of stomach problems, kidney disease, or certain heart conditions, acetaminophen is the safer fallback. It is also the better choice if you are already taking a blood thinner. But for most people with arthritis who can tolerate NSAIDs, acetaminophen alone is the weaker option.
Topical NSAIDs for Knee and Hand Arthritis
If your arthritis is in a joint close to the skin surface, especially the knee or hand, a topical NSAID gel or patch deserves serious consideration. The ACR guidelines give topical NSAIDs a strong recommendation for knee osteoarthritis, putting them on equal footing with oral NSAIDs.8PubMed Central. 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee – Section: RESULTS
Head-to-head trials have shown topical diclofenac provides pain relief, improved function, and reduced stiffness comparable to oral NSAIDs, with fewer systemic side effects.9PubMed Central. Topical Diclofenac, an Efficacious Treatment for Osteoarthritis: A Narrative Review – Section: Topical Diclofenac Efficacy in Osteoarthritis A network meta-analysis of randomized trials found that topical NSAIDs were effective and safe for osteoarthritis overall, with diclofenac patches appearing to be the most effective option for pain relief. No serious gastrointestinal or kidney side effects were observed in the trials or in broader population studies.10British Journal of Sports Medicine. Relative efficacy and safety of topical non-steroidal anti-inflammatory drugs for osteoarthritis: a systematic review and network meta-analysis of randomised controlled trials and observational studies
The OTC topical NSAID most widely available in the United States is diclofenac sodium gel (Voltaren Arthritis Pain). You apply it to the affected joint several times daily. The drug penetrates the skin and concentrates in the local tissue without flooding your bloodstream the way a pill does. That is why the stomach and kidney risks drop so dramatically. For hip arthritis, topical products are less useful because the joint sits too deep beneath muscle and fat for much of the drug to reach it. For hips, oral NSAIDs remain the primary OTC option.
Menthol, Camphor, and Capsaicin Creams
Walk down the pain-relief aisle and you will see a wall of creams, patches, and rubs containing menthol, camphor, capsaicin, or some combination. These are not NSAIDs. They work through different mechanisms, and the evidence behind them is less robust.
Menthol activates cold-sensing receptors in the skin, producing a cooling sensation that initially stimulates pain-sensing nerve fibers and then desensitizes them.11PubMed. The role and mechanism of action of menthol in topical analgesic products Camphor works through a related but distinct pathway, activating heat-sensing receptors while also blocking certain pain channels.12PubMed Central. Looking Back to Move Forward: The Current State of Research on the Clinical Applications of Camphor- and Menthol-Containing Agents The result is that tingling, warm-then-cool feeling you get from products like Bengay, IcyHot, or Tiger Balm. They provide temporary distraction from deeper joint pain, but studies evaluating them for osteoarthritis generally show only low-level evidence of pain reduction.13PubMed. Topical therapies for knee osteoarthritis
Capsaicin cream, derived from chili peppers, takes a different approach. It overstimulates pain-sensing nerve endings until they become less reactive. The ACR guidelines give capsaicin a conditional recommendation for knee osteoarthritis, though the effect is modest and requires consistent use over several weeks before you notice meaningful relief.4PubMed Central. 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee – Section: RESULTS The burning sensation during the first week or two puts a lot of people off before they give it a fair chance. If you can stick with it, capsaicin may be worth layering on top of an NSAID regimen, but on its own it is not a substitute.
Stomach, Heart, and Kidney Risks of Oral NSAIDs
NSAIDs earn the top efficacy spot, but they come with trade-offs that matter more the longer you use them and the older you get.
The stomach is the most familiar concern. NSAIDs reduce the protective mucus lining of the stomach and intestines, which can lead to irritation, ulcers, and bleeding.14PubMed Central. Effects of Non-steroidal Anti-inflammatory Drugs (NSAIDs) and Gastroprotective NSAIDs on the Gastrointestinal Tract: A Narrative Review Short-term use of ibuprofen or naproxen at OTC doses carries a higher risk of visible mucosal injury compared with placebo.15PubMed. A randomized, controlled comparison of ibuprofen at the maximal over-the-counter dose compared with prescription-dose celecoxib on upper gastrointestinal mucosal injury Taking NSAIDs with food or adding an over-the-counter acid reducer like famotidine can help, but the risk does not vanish entirely.
Heart risk is the trickier issue. A large randomized trial comparing celecoxib, naproxen, and ibuprofen in arthritis patients found that cardiovascular event rates were broadly similar across the three drugs, with all of them in the range of roughly 2 to 3 percent over the study period.16PubMed. Cardiovascular Safety of Celecoxib, Naproxen, or Ibuprofen for Arthritis However, naproxen appears to carry the lowest cardiovascular risk among common NSAIDs because of its weaker effect on the enzyme pathway linked to clotting and blood-vessel constriction.17PubMed Central. Clinical Pharmacology and Cardiovascular Safety of Naproxen A more recent target-trial analysis found that people starting ibuprofen had a higher rate of major vascular events compared with those starting naproxen.18European Heart Journal. Cardiovascular risks of ibuprofen versus naproxen: a target trial emulation If you have existing heart disease or significant risk factors, this distinction could tip the scale toward naproxen over ibuprofen, or toward topical NSAIDs to limit systemic exposure altogether.
Kidneys round out the risk triangle. NSAIDs reduce blood flow to the kidneys, and prolonged use is associated with acute kidney injury and, in some cases, chronic kidney disease.19PubMed Central. Kidney damage from nonsteroidal anti-inflammatory drugs-Myth or truth? Review of selected literature If you already have reduced kidney function, your doctor may steer you away from all oral NSAIDs.
Acetaminophen Safety Is Not a Free Pass
People often assume acetaminophen is harmless because it is gentler on the stomach. The liver tells a different story. A review of the safety literature found that acetaminophen use in the general population is linked to liver-function abnormalities, and there is evidence of liver failure from unintentional overdose.20PubMed Central. Safety of Paracetamol in Osteoarthritis: What Does the Literature Say? A modeling study estimated that acetaminophen at doses between 1,500 and 4,000 mg per day increased the risk of mild liver injury by about 23 percent compared with placebo, though the risk of moderate or severe injury was much smaller. At standard therapeutic doses, no clear dose-response relationship for liver damage was identified.21PubMed Central. Model-Based Assessment of the Liver Safety Profile of Acetaminophen to Support its Combination Use with Topical Diclofenac in Mild-to-Moderate Osteoarthritis Pain
The practical concern is that acetaminophen hides in dozens of other products: cold medicines, sleep aids, combination painkillers. It is easy to double up without realizing it, and once you push past 3,000 to 4,000 mg in a day, liver risk climbs fast. If you drink alcohol regularly, the threshold for trouble drops further. Acetaminophen is a fine medication used carefully, but treating it as consequence-free is a mistake.
Drug Interactions You Should Know About
If you take low-dose aspirin for heart protection, ibuprofen creates a specific problem: it competes for the same binding site on platelets that aspirin uses to prevent clots. Even a single OTC dose of ibuprofen can significantly blunt aspirin’s antiplatelet effect depending on when you take both drugs relative to each other.22PubMed. Prediction of time-dependent interaction of aspirin with ibuprofen using a pharmacokinetic/pharmacodynamic model Naproxen also interferes with aspirin’s antiplatelet action, as do several other NSAIDs.23PubMed. The antiplatelet effect of six non-steroidal anti-inflammatory drugs and their pharmacodynamic interaction with aspirin in healthy volunteers If you rely on daily aspirin, talk to your doctor before adding any oral NSAID. Timing the doses hours apart can help, but it is not a complete fix.
People on warfarin face a less obvious danger from topical products. Many OTC muscle rubs and arthritis creams contain methyl salicylate. It absorbs through the skin, and in patients on warfarin it can boost anticoagulation to dangerous levels, increasing the risk of bleeding.24PubMed Central. Adverse effect of topical methylsalicylate ointment on warfarin anticoagulation: an unrecognized potential hazard This interaction has been reported even with moderate use of topical methyl salicylate, not just excessive application.25PubMed. Potentiation of warfarin anticoagulation associated with topical methyl salicylate Check the active ingredients on any cream or patch before using it alongside a blood thinner.
Glucosamine, Chondroitin, and Other Supplements
Glucosamine and chondroitin are the supplements most people try first for arthritis. The evidence is mixed enough to leave even researchers unsure how to advise patients. A large federally funded trial found that glucosamine, chondroitin, and their combination were not significantly better than placebo at reducing knee pain by 20 percent overall. However, among the subset of participants with moderate-to-severe pain, the combination did outperform placebo significantly.26PubMed. Glucosamine, chondroitin sulfate, and the two in combination for painful knee osteoarthritis
A later meta-analysis of randomized trials found that chondroitin alone showed a meaningful benefit over placebo for pain, but glucosamine alone did not, and the combination did not either.27PubMed Central. Effectiveness and safety of glucosamine and chondroitin for the treatment of osteoarthritis: a meta-analysis of randomized controlled trials Separately, a meta-analysis looking at joint-space narrowing over three years of daily glucosamine use found a small structural benefit, suggesting it may slow the physical deterioration of the joint even if the pain relief is marginal.28Archives of Internal Medicine. Structural and Symptomatic Efficacy of Glucosamine and Chondroitin in Knee Osteoarthritis: A Comprehensive Meta-analysis The ACR guidelines give chondroitin a conditional recommendation for hand osteoarthritis specifically, but do not endorse glucosamine with the same confidence.4PubMed Central. 2019 American College of Rheumatology/Arthritis Foundation Guideline for the Management of Osteoarthritis of the Hand, Hip, and Knee – Section: RESULTS
Curcumin, the active compound in turmeric, has attracted growing interest. Narrative reviews note that the most consistent evidence for curcumin involves pain reduction and improved inflammatory markers in osteoarthritis and rheumatoid arthritis.29Journal of Education, Health and Sport. The role of curcumin in the management of pain and inflammation across clinical conditions. A narrative review Animal research suggests curcumin may also protect cartilage and reduce joint inflammation at a structural level.30PubMed Central. Curcumin and Vitamin D Supplement Attenuates Knee Osteoarthritis Progression in ACLT + MMx Rat Model: Effect on Cartilage Protection and Pain Reduction The catch is that curcumin is poorly absorbed in the gut unless formulated with enhancers like piperine (black pepper extract) or packaged in special delivery systems. As a supplement, it is worth experimenting with, but expecting it to replace an NSAID for significant arthritis pain is optimistic given the current evidence.
Osteoarthritis Versus Inflammatory Arthritis
Most of the evidence above applies to osteoarthritis, the wear-and-tear form that affects tens of millions of people. If you have rheumatoid arthritis, psoriatic arthritis, or another autoimmune form, OTC medications can still help with day-to-day pain, but they are not treating the underlying disease. Inflammatory arthritis requires prescription disease-modifying drugs that suppress the immune attack on your joints. Research shows that once people with rheumatoid arthritis start biologic disease-modifying therapies, their need for additional painkillers and anti-inflammatories tends to decrease as the underlying inflammation comes under control.31Journal of Clinical Pharmacy and Therapeutics. Use of Analgesic and Anti‐Inflammatory Medicines before and after Initiation of Biological Disease‐Modifying Antirheumatic Drugs for Rheumatoid Arthritis If your joint pain is persistent, symmetrical (both wrists, both knees), and accompanied by prolonged morning stiffness lasting more than 30 minutes, those are flags for inflammatory arthritis worth bringing to a doctor rather than managing solely with OTC products.
The Role of Placebo and Expectations
One underappreciated finding in arthritis research is just how powerful the placebo response is. In knee osteoarthritis trials, up to three-quarters of the pain reduction seen with active treatment has been attributed to the placebo effect.32PubMed Central. Placebo Effect Sizes in Clinical Trials of Knee Osteoarthritis Using Intra-Articular Injections of Biologic Agents A meta-analysis of placebo arms across non-surgical knee OA trials found that about 60 percent of studies showed at least a moderate improvement in the placebo group alone.33PubMed Central. Magnitude of the placebo response across non-surgical treatment modalities used for knee osteoarthritis: A meta-analysis with meta-regression
This does not mean arthritis drugs are fake. It means that the ritual of treatment itself, expecting relief, physically applying a cream, taking a pill at scheduled times, has genuine pain-modulating effects on the nervous system. It also helps explain why so many people swear by products with thin clinical evidence. If a menthol rub or a glucosamine tablet makes your knee feel better, that benefit is real to your brain even if the drug is only partly responsible. The practical lesson is that any treatment you believe in and use consistently will likely feel somewhat effective, which makes it trickier to judge whether a new product is truly working or whether you are responding to the act of doing something about your pain.
Putting Together a Practical OTC Strategy
A systematic review comparing oral NSAIDs and opioids for knee osteoarthritis found that both drug classes produced similar pain reduction once withdrawals were accounted for.34PubMed Central. Comparative pain reduction of oral non-steroidal anti-inflammatory drugs and opioids for knee osteoarthritis: systematic analytic review That finding is reassuring: OTC NSAIDs perform as well as stronger prescription painkillers for this condition, without the addiction risk. You do not need to escalate to more powerful drugs to get meaningful relief in most cases.
For the knee or hand, starting with a topical NSAID like diclofenac gel gives you effective local relief with minimal systemic risk. If that is not enough, adding an oral NSAID like naproxen, taken with food, is the next reasonable step. Acetaminophen can be layered on top if you want broader pain coverage, since it works through a different pathway and combining it with an NSAID is generally considered safe at standard doses. Capsaicin cream can add another layer for stubborn knee pain if you are willing to tolerate the initial burning phase. Supplements like chondroitin or curcumin are worth trying if you want to explore every avenue, but they should be additions to an NSAID strategy, not replacements for one. And regardless of what you take, the ACR’s strongest recommendations are actually for non-drug approaches: regular exercise, weight management if you are carrying extra pounds, and physical therapy. Medication manages symptoms. Movement and weight loss change the trajectory of the disease.
