What medications treat rheumatoid arthritis

Rheumatoid arthritis is treated with several types of medication that work in different ways. The main categories are disease-modifying antirheumatic drugs (DMARDs), which slow joint damage; biologic drugs, which target specific parts of the immune system; corticosteroids, which reduce inflammation quickly; and nonsteroidal anti-inflammatory drugs (NSAIDs), which ease pain and swelling. Most people take more than one type at the same time.

Your doctor will recommend a treatment plan based on how active your disease is, which joints are affected, your other health conditions, and how you respond to the first medication tried. The goal is to reach remission or low disease activity — meaning minimal pain, swelling, and joint damage — as early as possible. Starting treatment within the first few months after diagnosis gives the best chance of slowing or stopping permanent joint damage.

Key Takeaways

  • DMARDs like methotrexate are usually the first medication prescribed and work by slowing the immune system's attack on joints.
  • Biologic drugs target specific immune cells and are often added if DMARDs alone do not control symptoms well enough.
  • NSAIDs and corticosteroids manage pain and swelling but do not slow joint damage, so they are used alongside DMARDs, not instead of them.
  • Most people need to try more than one medication before finding the combination that works best for them.
  • Regular blood tests and doctor visits are necessary to check whether the medication is working and to watch for side effects.

Disease-modifying antirheumatic drugs (DMARDs)

Methotrexate is the most commonly prescribed DMARD and is often the first medication doctors recommend. It works by slowing the immune system's attack on the joints. Methotrexate is taken once a week, either as a pill or an injection. It can take 6 to 12 weeks to see full benefit, and blood tests are needed every 8 to 12 weeks to monitor liver and kidney function and blood cell counts.

Other DMARDs include sulfasalazine, leflunomide, and hydroxychloroquine. These are sometimes used alone in mild cases or combined with methotrexate or biologics in more active disease. Each has different side effects and monitoring requirements, which your doctor will discuss with you.

DMARDs can cause nausea, mouth sores, or hair loss in some people, and they increase infection risk slightly because they suppress immune function. Women who might become pregnant should discuss DMARD use with their doctor, as some can harm a developing baby. If you develop signs of infection — fever, chills, or unusual tiredness — contact your doctor right away.

Biologic drugs

Biologic medications are made from living cells and target specific parts of the immune system that drive rheumatoid arthritis. Common types include TNF inhibitors (such as etanercept, infliximab, and adalimumab), IL-6 inhibitors (such as tocilizumab), and JAK inhibitors (such as baricitinib and tofacitinib). Biologics are usually added when methotrexate or other DMARDs alone do not control symptoms well enough.

Biologic drugs are given by injection under the skin, injection into a vein, or by mouth, depending on the drug. Most are injected every 1 to 4 weeks. They work faster than traditional DMARDs — many people notice improvement within 2 to 4 weeks — and they can be very effective at stopping joint damage. However, they are more expensive than traditional DMARDs and require regular monitoring.

Because biologics suppress immune function, they increase the risk of serious infections, including tuberculosis. Before starting a biologic, your doctor will test you for tuberculosis and may recommend vaccines. Tell your doctor when ready if you develop fever, chills, cough, or other signs of infection. Biologics are not recommended during active infections and should be discussed carefully if you have a history of cancer or heart failure.

NSAIDs and corticosteroids

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, and prescription-strength celecoxib reduce pain and swelling. They work quickly — often within hours — but they do not slow joint damage. NSAIDs are used alongside DMARDs to manage symptoms while waiting for the DMARD to take effect, or to control breakthrough pain. They can be taken as needed or regularly, depending on your doctor's recommendation.

NSAIDs carry risks, especially with long-term use. They can cause stomach ulcers, increase blood pressure, and raise the risk of heart attack or stroke in some people. If you take NSAIDs regularly, your doctor may recommend a medication to protect your stomach. Tell your doctor if you have a history of ulcers, heart disease, high blood pressure, or kidney problems before taking NSAIDs regularly.

Corticosteroids like prednisone reduce inflammation and pain quickly and are often prescribed at low doses for short periods — for example, while waiting for a DMARD to work. They can also be injected directly into a swollen joint for rapid relief. Corticosteroids are powerful but have side effects with long-term use, including bone loss, weight gain, increased infection risk, and mood changes. Your doctor will use the lowest dose for the shortest time possible.

How your doctor chooses a treatment plan

Your doctor will assess how active your rheumatoid arthritis is using blood tests (looking for inflammatory markers like CRP and ESR, and the rheumatoid factor or anti-CCP antibody), imaging such as X-rays or ultrasound, and your report of symptoms. They will also ask about your other medical conditions, medications you take, and whether you might become pregnant, because these factors affect which drugs are safe for you.

Most doctors follow a "treat-to-target" approach: they start with methotrexate or another DMARD and adjust the dose or add a second medication every 3 to 6 months until you reach remission or low disease activity. If the first DMARD does not work well enough after 3 months, a biologic is usually added rather than switching to a different DMARD alone. This aggressive early approach has been shown to prevent permanent joint damage better than waiting to see if one drug works.

Your treatment plan may change over time. If your disease goes into remission, your doctor may lower doses or stop some medications. If new symptoms appear or old ones return, medications may be added back or changed. This is normal and expected.

Monitoring and side effects

Regular blood tests are essential when taking DMARDs or biologics. Methotrexate requires testing every 8 to 12 weeks to check liver and kidney function and blood cell counts. Biologics also require periodic blood tests to watch for signs of infection or other problems. Your doctor will tell you how often you need testing based on which medications you take.

Keep a list of any side effects you notice — nausea, rashes, unusual tiredness, mouth sores, or signs of infection — and report them at your next visit or sooner if they are severe. Many side effects can be managed by adjusting the dose, taking the medication with food, or adding another medication. Do not stop taking your medication without talking to your doctor first, even if you feel better, because stopping suddenly can cause disease flare-up and joint damage.

Tell all your doctors and dentists that you take rheumatoid arthritis medication. Some medications interact with others, and your dentist needs to know about your immune-suppressing drugs before procedures. If you need surgery, tell your surgeon about your RA medications — some may need to be paused temporarily.

When to contact your doctor

Contact your doctor if you develop fever, chills, cough, or other signs of infection; if you have unusual bruising or bleeding; if you notice new or worsening joint pain or swelling; or if you have side effects that bother you. These warrant a call within a few days. Seek when ready care if you have severe chest pain, difficulty breathing, or signs of a serious allergic reaction such as swelling of the face or throat.

If you are planning to become pregnant, talk to your doctor before stopping or starting any RA medication. Some drugs are safe during pregnancy and some are not. Your doctor can help you plan the safest approach for you and your baby.

Frequently Asked Questions

How long does it take for rheumatoid arthritis medication to work?

NSAIDs and corticosteroids work within hours to days. Traditional DMARDs like methotrexate take 6 to 12 weeks to show full benefit. Biologic drugs often work faster — many people notice improvement within 2 to 4 weeks. Your doctor will reassess your response at regular visits and adjust your treatment if needed.

Can I stop taking my medication if I feel better?

No. Stopping medication without your doctor's guidance can cause disease flare-up and permanent joint damage. Even if you feel well, the medication is working to prevent damage. Your doctor may lower doses or stop medications if you reach remission, but this decision must be made together based on blood tests and imaging, not on how you feel alone.

What if the first medication does not work?

This is common. If methotrexate or another DMARD does not control your symptoms well enough after 3 months, your doctor will usually add a biologic or switch to a different medication. It may take trying two or three combinations before finding what works best for you. This is why regular follow-up visits are important.

Are biologic drugs safer than traditional DMARDs?

Both types carry risks. Biologics work faster and may prevent more joint damage, but they increase infection risk more than traditional DMARDs. Traditional DMARDs like methotrexate can affect liver and kidney function. Your doctor will choose based on your individual situation — how active your disease is, your other health conditions, and your infection risk.

Can I take over-the-counter pain relievers with my RA medication?

Some over-the-counter NSAIDs like ibuprofen can be used short-term alongside your prescription medications, but check with your doctor first. Do not take them regularly without medical supervision, as they can cause stomach problems and interact with other drugs. Acetaminophen is often a safer choice for occasional pain relief.
