There is no single best arthritis medicine because the right choice depends entirely on which type of arthritis you have and how severe it is. Osteoarthritis, rheumatoid arthritis, and gout each respond to different treatments, and what works brilliantly for one can be useless for another. Here’s what the current evidence says about the most effective options for each.
Osteoarthritis: NSAIDs Lead the Pack
For osteoarthritis, the wear-and-tear type that affects most people, anti-inflammatory painkillers (NSAIDs) remain the strongest recommended option. Familiar over-the-counter choices include ibuprofen and naproxen. These provide temporary but meaningful improvement in both pain and physical function for hand, knee, and hip osteoarthritis.
If your osteoarthritis is in the knee, you have an extra option worth knowing about: topical NSAIDs, the kind you rub directly on the skin. Gels and creams containing diclofenac offer pain relief equivalent to oral pills for knee osteoarthritis, with far fewer stomach and cardiovascular side effects. The American College of Rheumatology and Arthritis Foundation guidelines actually recommend topical NSAIDs as a preferred early choice for knee OA for exactly this reason.
When you do take oral NSAIDs, the guidance is straightforward: use the lowest dose that controls your pain, for the shortest time you need it. Long-term daily use raises the risk of stomach ulcers, kidney problems, and cardiovascular events, especially in older adults. Many people cycle on and off NSAIDs as flare-ups come and go rather than taking them continuously.
Acetaminophen (Tylenol) is sometimes suggested as a gentler alternative, but recent guidelines have moved away from it as a primary recommendation for osteoarthritis. It’s less effective than NSAIDs for inflammatory joint pain, though it can still help some people with mild symptoms.
Rheumatoid Arthritis: Methotrexate Is the Gold Standard
Rheumatoid arthritis is an autoimmune condition where the immune system attacks joint tissue, causing progressive damage. The treatment goal is not just pain relief but slowing or stopping that damage. This requires a category of drugs called disease-modifying antirheumatic drugs, or DMARDs.
For moderate to high disease activity, methotrexate is considered the best initial treatment for rheumatoid arthritis. It’s been the backbone of RA care for decades, and nothing has displaced it. Most people start on an oral dose once per week, typically reaching an effective level within the first six weeks of treatment. You won’t feel the effects immediately. Joint swelling and tenderness generally begin improving between 4 and 8 weeks after starting, so patience during that window matters.
Because methotrexate works by dialing down immune activity, it comes with side effects like nausea, fatigue, and mouth sores. A weekly folic acid supplement is standard practice to reduce these. If the oral version causes too much stomach trouble, a subcutaneous injection (self-administered at home) often works better with fewer side effects.
For people with low disease activity, the recommended starting points are gentler medications: hydroxychloroquine or sulfasalazine first, with methotrexate or leflunomide as next steps if needed.
Biologics and Targeted Therapies for RA
When methotrexate alone isn’t enough, the next step is usually adding a biologic. These are injectable or infused medications that block specific parts of the immune response driving joint destruction. The most well-known target a protein called TNF-alpha. Adalimumab (originally sold as Humira) and etanercept (Enbrel) are the most widely prescribed in this class.
Biologics can be transformative for people who don’t respond adequately to methotrexate, sometimes putting the disease into near-complete remission. The tradeoff is cost and infection risk, since suppressing immune function makes you more vulnerable to illness. The cost issue, however, is shifting. Several interchangeable biosimilars for adalimumab were approved in 2024, and the price difference is dramatic: the original product costs roughly $3,154 per dose at wholesale, while biosimilar versions average around $515 per dose. That’s more than an 80% reduction, making these treatments far more accessible than they were just a few years ago.
Another class, JAK inhibitors (taken as daily pills rather than injections), became popular as a more convenient alternative to biologics. But the FDA now requires their strongest safety warning on these medications after a large clinical trial linked one of them to increased risks of serious heart events like heart attack and stroke, blood clots, and certain cancers including lymphoma and lung cancer. These drugs are still available but are generally reserved for people who haven’t responded to other treatments, particularly if they don’t have additional cardiovascular risk factors or a history of smoking.
Gout: Stopping Flares and Preventing Them
Gout requires a two-phase approach: treating the agonizing flares when they happen, then lowering uric acid levels to prevent them from coming back.
For acute flares, three options work equally well: low-dose colchicine, NSAIDs, or corticosteroids (taken orally or injected into the joint). The choice usually comes down to what your body tolerates best. Colchicine works best when taken within the first 12 to 24 hours of a flare. NSAIDs are a solid choice if you don’t have kidney or stomach issues. Corticosteroids are often preferred for people who can’t take either of the other two.
For long-term prevention, the goal is getting uric acid in the blood down to 6 mg/dL or lower. This is typically done with a daily medication that reduces uric acid production. Doses are increased gradually every two to five weeks until that target is reached. Staying on this medication consistently is what keeps flares from recurring, and stopping it is the most common reason gout comes back.
Joint Injections for Targeted Relief
When pain is concentrated in one or two joints, corticosteroid injections delivered directly into the joint space can provide significant relief without the systemic side effects of oral medications. The effect typically lasts around two months, sometimes longer for chronic pain. These injections are commonly used in knees and hips for osteoarthritis, and in any inflamed joint during an RA or gout flare.
The limitation is frequency. Repeated injections into the same joint can accelerate cartilage breakdown over time, so most doctors limit them to three or four per joint per year.
Glucosamine and Chondroitin: The Evidence Is Weak
These are among the most popular joint supplements sold, and many people with osteoarthritis try them before or alongside conventional medicine. The current evidence, however, is not encouraging. A 2024 meta-analysis published in Osteoarthritis and Cartilage found that adding glucosamine, either alone or combined with chondroitin, to an exercise program had no significant effect on knee pain or physical function compared with exercise alone.
This doesn’t mean no individual has ever felt better taking them. But in controlled studies, the supplements consistently fail to outperform placebo by a meaningful margin. If you’ve been taking them for several months without noticeable improvement, the research suggests they’re unlikely to start working. Your money is probably better spent on physical therapy or other proven approaches.
Exercise Matters More Than Most People Realize
Across all types of arthritis, regular physical activity consistently shows up as one of the most effective interventions, sometimes rivaling medication for pain reduction and functional improvement in osteoarthritis. Low-impact activities like walking, swimming, cycling, and strength training reduce stiffness, strengthen the muscles supporting your joints, and help manage weight (which directly reduces joint stress). For knee osteoarthritis in particular, exercise programs are considered a core treatment, not just a supplement to medication.
The instinct to rest painful joints is understandable but counterproductive in most cases. Joints that aren’t moved regularly become stiffer and weaker, creating a cycle of increasing pain and disability. Starting slowly and building up gradually is the practical path forward, ideally with guidance from a physical therapist who can tailor exercises to your specific joints and limitations.
