Disease-modifying antirheumatic drugs (DMARDs) are the primary treatment for RA. They are a diverse collection of drugs, grouped by use and convention. They have been found to improve symptoms, decrease joint damage, and improve overall functional abilities. DMARDs should be started early in the disease as they result in disease remission in approximately half of people and improved outcomes overall.

The following drugs are considered as DMARDs: methotrexate, hydroxychloroquine, sulfasalazine, leflunomide, TNF-alpha inhibitors (certolizumab, infliximab and etanercept), abatacept, and anakinra. Rituximab and tocilizumab are monoclonal antibodies and are also DMARDs.

The most commonly used agent is methotrexate with other frequently used agents including sulfasalazine and leflunomide. Sodium aurothiomalate (gold) and cyclosporin are less commonly used due to more common adverse effects. Agents may be used in combinations. Methotrexate is the most important and useful DMARD and is usually the first treatment. Adverse effects should be monitored regularly with toxicity including gastrointestinal, hematologic, pulmonary, and hepatic. Side effects such as nausea, vomiting or abdominal pain can be reduced by taking folic acid.

A 2015 Cochrane review found rituximab with methotrexate to be effective in improving symptoms compared to methotrexate alone. Rituximab works by depicting levels of B-cells (immune cell that is involved in inflammation). People taking rituximab had improved pain, function, reduced disease activity and reduced joint damage based on x-ray images. After 6 months, 21% more people had improvement in their symptoms using rituximab and methotrexate.

Biological agents should generally only be used if methotrexate and other conventional agents are not effective after a trial of three months. They are associated with a higher rate of serious infections as compared to other DMARDs. Biological DMARD agents used to treat rheumatoid arthritis include: tumor necrosis factor alpha (TNFα) blockers such as infliximab; interleukin 1 blockers such as anakinra, monoclonal antibodies against B cells such as rituximab, and tocilizumab T cell co-stimulation blocker such as abatacept. They are often used in combination with either methotrexate or leflunomide. Abatacept should not be used at the same time as other biologics. In those who are well controlled on TNF blockers decreasing the dose does not appear to affect overall function. Persons should be screened for latent tuberculosis before starting any TNF blockers therapy to avoid reactivation.

TNF blockers and methotrexate appear to have similar effectiveness when used alone and better results are obtained when used together. TNF blockers appear to have equivalent effectiveness with etanercept appearing to be the safest. Abatacept appears effective for RA with 20% more people improving with treatment than without but long term safety studies are yet unavailable. However, there is a lack of evidence to distinguish between the biologics available for RA. Issues with the biologics include their high cost and association with infections including tuberculosis.

Glucocorticoids can be used in the short term and at the lowest dose possible for flare-ups and while waiting for slow-onset drugs to take effect.

Non-NSAID drugs to relieve pain, like paracetamol may be used to help relieve the pain symptoms; they do not change the underlying disease.

NSAIDs reduce both pain and stiffness in those with RA but do not affect the underlying disease and appear to have no effect on people's long term disease course and thus are no longer first line agents. NSAIDs should be used with caution in those with gastrointestinal, cardiovascular, or kidney problems. Use of methotrexate together with NSAIDS is safe, if adequate monitoring is done. COX-2 inhibitors, such as celecoxib, and NSAIDs are equally effective.

Due to the variety of symptoms and organ system involvement with SLE, its severity in an individual must be assessed in order to successfully treat SLE. Mild or remittent disease may, sometimes, be safely left untreated. If required, nonsteroidal anti-inflammatory drugs and antimalarials may be used. Medications such as prednisone, mycophenolic acid and tacrolimus have been used in the past.

Disease-modifying antirheumatic drugs (DMARDs) are used preventively to reduce the incidence of flares, the progress of the disease, and the need for steroid use; when flares occur, they are treated with corticosteroids. DMARDs commonly in use are antimalarials such as hydroxychloroquine and immunosuppressants (e.g. methotrexate and azathioprine). Hydroxychloroquine is an FDA-approved antimalarial used for constitutional, cutaneous, and articular manifestations. Hydroxychloroquine has relatively few side effects, and there is evidence that it improves survival among people who have SLE.

Cyclophosphamide is used for severe glomerulonephritis or other organ-damaging complications. Mycophenolic acid is also used for treatment of lupus nephritis, but it is not FDA-approved for this indication, and FDA is investigating reports that it may be associated with birth defects when used by pregnant women.

Typically the medications first prescribed for psoriatic arthritis are NSAIDs such as ibuprofen and naproxen, followed by more potent NSAIDs like diclofenac, indomethacin, and etodolac. NSAIDs can irritate the stomach and intestine, and long-term use can lead to gastrointestinal bleeding. Coxibs (COX-2 inhibitors) e.g. Celecoxib or Etoricoxib, are associated with a statistically significant 50 to 66% relative risk reduction in gastrointestinal ulcers and bleeding complications compared to traditional NSAIDs, but carry an increased rate of cardiovascular events such as myocardial infarction (MI) or heart attack, and stroke. Both COX-2 inhibitors and other non-selective NSAIDS have potential adverse effects that include damage to the kidneys.

There is no cure for dermatomyositis, but the symptoms can be treated. Options include medication, physical therapy, exercise, heat therapy (including microwave and ultrasound), orthotics and assistive devices, and rest. The standard treatment for dermatomyositis is a corticosteroid drug, given either in pill form or intravenously. Immunosuppressant drugs, such as azathioprine and methotrexate, may reduce inflammation in people who do not respond well to prednisone. Periodic treatment using intravenous immunoglobulin can also improve recovery. Other immunosuppressive agents used to treat the inflammation associated with dermatomyositis include cyclosporine A, cyclophosphamide, and tacrolimus. Physical therapy is usually recommended to prevent muscle atrophy and to regain muscle strength and range of motion. Many individuals with dermatomyositis may need a topical ointment, such as topical corticosteroids, for their skin disorder. They should wear a high-protection sunscreen and protective clothing. Surgery may be required to remove calcium deposits that cause nerve pain and recurrent infections.

Antimalarial medications, especially hydroxychloroquine and chloroquine, are used to treat the rashes, as they are in similar conditions.

Rituximab is used when people don't respond to other treatments.

As of 2016, treatments for amyopathic dermatomyositis in adults did not have a strong evidence base; published treatments included antimalarial medications, steroids, taken or orally or applied to the skin, calcineurin inhibitors applied to the skin, dapsone, Intravenous immunoglobulin (IVIG), methotrexate, azathioprine, and mycophenolate mofetil. None appear to be very effective but among them, IVIG has had the best outcomes.

These are used in persistent symptomatic cases without exacerbation. Rather than just reducing pain and inflammation, this class of drugs helps limit the amount of joint damage that occurs in psoriatic arthritis. Most DMARDs act slowly and may take weeks or even months to take full effect. Drugs such as methotrexate or leflunomide are commonly prescribed; other DMARDS used to treat psoriatic arthritis include cyclosporin, azathioprine, and sulfasalazine. These immunosuppressant drugs can also reduce psoriasis skin symptoms but can lead to liver and kidney problems and an increased risk of serious infection.

Treatment with either glucocorticoids, methotrexate, anakinra, or tocilizumab has been examined. Anakinra has been shown to resolve the clinical features of the disease in 87% of patients. It also induces remission in half of corticosteroid-resistant patients. The results of another study were similar, with half of the patients responding to treatment with Anakinra. Canakinumab, an antibody to

interleukin-1 beta, is indicated for treatment in patients who respond poorly to other treatments.

The treatment of juvenile arthritis includes medications, physical therapy, splints and in severe cases surgery. These treatments are focused on reducing swelling, relieving pain and maintaining full movement of joints. Children are encouraged to be involved in extra-curricular activities, physical activity when possible, and to live a "normal" life.

Before the advent of modern treatments such as prednisone, intravenous immunoglobulin, plasmapheresis, chemotherapies, and other drugs, the prognosis was poor.

The cutaneous manifestations of dermatomyositis may or may not improve with therapy in parallel with the improvement of the myositis. In some people, the weakness and rash resolve together. In others, the two are not linked, with one or the other being more challenging to control. Often, cutaneous disease persists after adequate control of the muscle disease.

The risk of death from the condition is much higher if the heart or lungs are affected.

JIA is best treated by a multidisciplinary team. The major emphasis of treatment for JIA is to help the child regain normal level of physical and social activities. This is accomplished with the use of physical therapy, pain management strategies, and social support. Another emphasis of treatment is to control inflammation and extra-articular symptoms quickly. Doing so should help to reduce joint damage and other symptoms, which will help reduce levels of permanent damage leading to disability.

Beneficial advances in drug treatment have been made over the last 20 years. Most children are treated with nonsteroidal anti-inflammatory drugs and intra-articular corticosteroid injections. Methotrexate, a disease-modifying antirheumatic drug (DMARD) is a powerful drug which helps suppress joint inflammation in the majority of JIA patients with polyarthritis (though less useful in systemic arthritis). Newer drugs have been developed recently, such as TNF alpha blockers, such as etanercept. No controlled evidence supports the use of alternative remedies such as specific dietary exclusions, homeopathic treatment, or acupuncture. However, an increased consumption of omega-3 fatty acids proved to be beneficial in two small studies.

Celecoxib has been found effective in one study.

Other aspects of managing JIA include physical and occupational therapy. Therapists can recommend the best exercise and also make protective equipment. Moreover, the child may require the use of special supports, ambulatory devices, or splints to help them ambulate and function normally.

Surgery is only used to treat the most severe cases of JIA. In all cases, surgery is used to remove scars and improve joint function.

Home remedies that may help JIA includes getting regular exercises to increase muscle strength and joint flexibility. Swimming is perhaps the best activity for all children with JIA. Stiffness and swelling can also be reduced with application of cold packs, but a warm bath or shower can also improve joint mobility.

In the future, genetic testing may be available allowing earlier detection of JIA. Early detection will help determine the severity of the disease in each child and help identify which therapies will be the most effective and beneficial treatment options.

Treatments for autoimmune disease have traditionally been immunosuppressive, anti-inflammatory, or palliative. Managing inflammation is critical in autoimmune diseases. Non-immunological therapies, such as hormone replacement in Hashimoto's thyroiditis or Type 1 diabetes mellitus treat outcomes of the autoaggressive response, thus these are palliative treatments. Dietary manipulation limits the severity of celiac disease. Steroidal or NSAID treatment limits inflammatory symptoms of many diseases. IVIG is used for CIDP and GBS. Specific immunomodulatory therapies, such as the TNFα antagonists (e.g. etanercept), the B cell depleting agent rituximab, the anti-IL-6 receptor tocilizumab and the costimulation blocker abatacept have been shown to be useful in treating RA. Some of these immunotherapies may be associated with increased risk of adverse effects, such as susceptibility to infection.

Helminthic therapy is an experimental approach that involves inoculation of the patient with specific parasitic intestinal nematodes (helminths). There are currently two closely related treatments available, inoculation with either Necator americanus, commonly known as hookworms, or Trichuris Suis Ova, commonly known as Pig Whipworm Eggs.

T cell vaccination is also being explored as a possible future therapy for autoimmune disorders.

There are no prospective randomized controlled trials studying therapies for relapsing polychondritis. Evidence for efficacy of treatments is based on case reports and series of small groups of patients.

For mild cases limited to joint pain or arthritis, oral nonsteroidal anti-inflammatory drugs (NSAIDs) may be used. Other treatments typically involve medications to suppress the immune system. Corticosteroids are frequently used for more serious disease. Steroid-sparing medications such as azathioprine or methotrexate may be used to minimize steroid doses and limit the side effects of steroids. For severe disease cyclophosphamide is often given in addition to high dose intravenous steroids.

Once a diagnosis of JDMS is made, the treatment is often a 3-day course of Intravenous ("pulse") steroids (methylprednisolone, Solu-Medrol), followed by a high dose of oral prednisone (usually 1–2 mg/kg of body weight) for several weeks. This action usually brings the disease under control, lowering most lab tests to or near normal values. Some minor improvement in muscle symptoms may also be seen in this time, but normally it takes a long time for full muscle strength to be regained.

Once the disease process is under control, oral steroids are tapered gradually to minimize their side effects. Often, steroid-sparing drugs, such as methotrexate (a chemotherapy drug) or other DMARDs, are given to compensate for the reduction in oral steroids. Once the oral steroids are reduced to a less toxic level, the sparing agents can also be gradually withdrawn. Lab results are closely monitored during the tapering process to ensure that the disease does not recur.

In the cases where steroids or second-line drugs are not tolerated or are ineffective, there are other treatments that can be tried. These include other chemotherapy drugs, such as ciclosporin, infliximab, or other DMARDs. Another is intravenous immunoglobulin (IVIg), a blood product that has been shown to be very effective against JDMS.

To treat the skin rash, anti-malarial drugs, such as hydroxychloroquine (Plaquenil) are usually given. Topical steroid creams (hydrocortisone) may help some patients, and anti-inflammatory creams (such as tacrolimus) are proving to be very effective. Dry skin caused by the rash can be combated by regular application of sunscreen or any moisturizing cream. Most JDM patients are very sensitive to sun exposure, and sunburn may be a disease activity trigger in some, so daily application of high-SPF sunscreen is often recommended.

There are several types of medications that are used for the treatment of arthritis. Treatment typically begins with medications that have the fewest side effects with further medications being added if insufficiently effective.

Depending on the type of arthritis, the medications that are given may be different. For example, the first-line treatment for osteoarthritis is acetaminophen (paracetamol) while for inflammatory arthritis it involves non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Opioids and NSAIDs are less well tolerated.

Rheumatoid arthritis (RA) is autoimmune so, in addition to pain medications and anti-inflammatory drugs, is treated with another category of drug called disease-modifying antirheumatic drugs (DMARDs), which act on the immune system to slow down the progression of RA. An example of this type of drug is methotrexate.

Treatment largely depends upon individual disease progression and the nature of presenting symptoms. Antimalarials, corticosteroids, and other drugs may be prescribed, if deemed appropriate by the treating physician.

The major types of medications used to treat ankylosing spondylitis are pain-relievers and drugs aimed at stopping or slowing the progression of the disease. All of these have potentially serious side effects. Pain-relieving drugs come in two major classes:

- The mainstay of therapy in all seronegative spondyloarthropathies are anti-inflammatory drugs, which include NSAIDs such as ibuprofen, phenylbutazone, diclofenac, indomethacin, naproxen and COX-2 inhibitors, which reduce inflammation and pain. Indomethacin is a drug of choice. 2012 research showed that those with AS and elevated levels of acute phase reactants seem to benefit most from continuous treatment with NSAIDs.

- Opioid painkillers

Medications used to treat the progression of the disease include the following:

- Disease-modifying antirheumatic drugs (DMARDs) such as sulfasalazine can be used in people with peripheral arthritis. For axial involvement, evidence does not support sulfasalazine. Other DMARDS, such as methotrexate, did not have enough evidence to prove their effect. Generally, systemic corticosteroids were not used due to lack of evidence. Local injection with corticosteroid can be used for certain people with peripheral arthritis.

- Tumor necrosis factor-alpha (TNFα) blockers (antagonists), such as the biologics etanercept, infliximab, golimumab and adalimumab, have shown good short-term effectiveness in the form of profound and sustained reduction in all clinical and laboratory measures of disease activity. Trials are ongoing to determine their long-term effectiveness and safety. The major drawback is the cost. An alternative may be the newer, orally-administered non-biologic apremilast, which inhibits TNF-α secretion, but a recent study did not find the drug useful for ankylosing spondylitis.

- Anti-interleukin-6 inhibitors such as tocilizumab, currently approved for the treatment of rheumatoid arthritis, and rituximab, a monoclonal antibody against CD20, are also undergoing trials.

- Interleukin-17A inhibitor secukinumab is an option for the treatment of active ankylosing spondylitis that has responded inadequately to (TNFα) blockers.

Further research is required to determine if transcutaneous electrical nerve stimulation (TENS) for knee osteoarthritis is effective for controlling pain.

Low level laser therapy may be considered for relief of pain and stiffness associated with arthritis. Evidence of benefit is tentative.

Pulsed electromagnetic field therapy has tentative evidence supporting improved functioning but no evidence of improved pain in osteoarthritis. The FDA has not approved PEMF for the treatment of arthritis. In Canada, PEMF devices are legally licensed by Health Canada for the treatment of pain associated with arthritic conditions.

There is no cure for AS, although treatments and medications can reduce symptoms and pain.

Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to treat musculoskeletal symptoms. For individuals with severe complications, corticosteroids or immunosuppressive drugs may be prescribed, and sometimes IVIG (intravenous immunoglobulin). Also, disease-modifying antirheumatic drugs (DMARDs) such as methotrexate may be helpful. Hydroxychloroquine (Plaquenil) is another option and is generally considered safer than methotrexate. However, these prescribed drugs have a range of side effects such as nausea, loss of appetite, dizziness, hair loss, stomach aches/cramps, headache, liver toxicity, and increased risk of infections. Also, people who take drugs to suppress the immune system are more likely to develop cancer later.

RS3PE responds excellently to low dose corticosteroids, with sustained and often complete remission. Non-steroidal anti-inflammatory drugs (NSAIDs) have also been used. Hydroxychloroquine has proven effective in some cases.

Treatments are generally directed toward stopping the inflammation and suppressing the immune system. Typically, corticosteroids such as prednisone are used. Additionally, other immune suppression drugs, such as cyclophosphamide and others, are considered. In case of an infection, antimicrobial agents including cephalexin may be prescribed. Affected organs (such as the heart or lungs) may require specific medical treatment intended to improve their function during the active phase of the disease.

For systemic symptoms, including fatigue, joint pain, myositis and neuropathy, biologic immunosuppressant drugs such as rituximab and belimumab that work via B-cell pathology are often used and have less toxic profiles than traditional immunosuppressive regimens.

Topical treatment for the skin changes of scleroderma do not alter the disease course, but may improve pain and ulceration. A range of NSAIDs (nonsteroidal anti-inflammatory drugs) can be used to ease painful symptoms, such as naproxen. There is limited benefit from steroids such as prednisone. Episodes of Raynaud's phenomenon sometimes respond to nifedipine or other calcium channel blockers; severe digital ulceration may respond to prostacyclin analogue iloprost, and the dual endothelin-receptor antagonist bosentan may be beneficial for Raynaud's phenomenon. The skin tightness may be treated systemically with methotrexate and ciclosporin. and the skin thickness treated with penicillamine.
