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.

Non-sedating antihistamines that block the histamine H1 receptors are the first line of therapy. First generation antihistamines such as diphenhydramine or hydroxyzine block both central and peripheral H1 receptors and can be sedating. Second generation antihistamines such as loratadine, cetirizine, or desloratadine selectively antagonize the peripheral H1 receptors and are less sedating, less anticholinergic, and generally preferred over the first generation antihistamines.

People who don’t respond to the maximum dose of H1 antihistamines may benefit from increasing the dose, then to switching to another non-sedating antihistamine, then to adding a leukotriene antagonist, then to using an older antihistamine, then to using systemic steroids and finally to using ciclosporin or omalizumab.

Corticosteroids are the mainstay of therapy with a 90% response rate in some studies. Appropriate duration of steroid treatment is unknown and relapse often necessitates long term treatment. Various steroid sparing agents e.g. sodium cromoglycate (a stabilizer of mast cell membranes), ketotifen (an antihistamine), and montelukast (a selective, competitive leukotriene receptor antagonist) have been proposed, centering on an allergic hypothesis, with mixed results. An elimination diet may be successful if a limited number of food allergies are identified.

Oral glucocorticoids are effective in controlling symptoms of chronic hives however they have an extensive list of adverse effects such as adrenal suppression, weight gain, osteoporosis, hyperglycemia, etc. Therefore, their use should be limited to a couple of weeks. In addition, one study found that systemic glucocorticoids combined with antihistamines did not hasten the time to symptom control compared with antihistamines alone.

Observation is acceptable if the lesions are neither symptomatic nor disfiguring. Intralesional or oral steroids can shrink the nodules, but seldom result in cure.

Cyclosporine has been reported to induce remission in patients with Kimura's disease, but recurrence of the lesions have been observed once this therapy is stopped.

Cetirizine is an effective agent in treating its symptoms. Cetirizine's properties of being effective both in the treatment of pruritus (itching) and as an anti-inflammatory agent make it suitable for the treatment of the pruritus associated with these lesions. In a 2005 study, the American College of Rheumatology conducted treatments initially using prednisone, followed by steroid dosages and azathioprine, omeprazole, and calcium and vitamin D supplements over the course of two years. The skin condition of the patient began to improve and the skin lesions lessened. However, there were symptoms of cushingoid and hirsutism observed before the patient was removed from the courses of steroids and placed on 10 mg/day of cetirizine to prevent skin lesions; an agent suitable for the treatment of pruritus associated with such lesions. Asymptomatically, the patient's skin lesions disappeared after treatment with cetirizine, blood eosinophil counts became normal, corticosteroid effects were resolved, and a remission began within a period of two months. It is also thought that the inhibition of eosinophils may be the key to treatment of Kimura's disease due to the role of eosinophils, rather than other cells with regards to the lesions of the skin.

Radiotherapy has been used to treat recurrent or persistent lesions. However, considering the benign nature of this disease, radiation should be considered only in cases of recurrent, disfiguring lesions.

Surgery has been considered the mainstay of therapy. However, recurrence after surgery is common.

In 2011, an eight-year-old boy had presented with a firm, nontender, nonfluctuating 15-12-cm mass on the left side of the neck involving the lateral region of the neck and jaw and a 5- to 7-cm mass on the right side of his neck. He had an eosinophil concentration of 36% (absolute count: 8172/ml), his IgE level was 9187 IU/ml. He was diagnosed with Kimura's disease. Initially treated with corticosteroids, he was given a single dose of intravenous immunoglobulin (IVIG) as a steroid-sparing agent after the disease flared while tapering prednisone. After IVIG administration, improvement was rapid, both left and right cervical masses diminished to less than 1 cm and his eosinophil and IgE levels returned to normal range. He has been free of disease during a six-year follow-up. IVIG may have value in the treatment of Kimura's disease.

A study is going on to assess the efficacy of tacrolimus on Kimura's disease. One case has so far been described. A patient with refractory Kimura's disease after surgery and treatment with prednisone was treated with tacrolimus. Tacrolimus (FK-506) was administered at an initial dosage of 1 mg every 12 hours, and FK-506 concentration in the blood was monitored monthly. FK-506 blood concentration was controlled within 5 to 15 μg/l. After 6 months, the dosage of tacrolimus was reduced to 0.5 mg daily for another 2 months and then treatment was stopped. Swelling of the bilateral salivary glands disappeared within the first week. No serious side effects were noted and the disease has not recurred in the 2 years of follow-up. Tacrolimus may be an effective treatment for patients with Kimura's disease, but more research is needed to determine its long-term efficacy and safety, as well as its mechanism of action.

Prevention focuses on improving sanitation of water and food sources.

Treatment focuses on addressing the central components of intestinal inflammation, bacterial overgrowth and nutritional supplementation.

Exercise is a promising mechanism of prevention and treatment for various diseases characterized by neuroinflammation. Aerobic exercise is used widely to reduce inflammation in the periphery. Exercise has been shown to decreases proliferation of microglia in the brain, decrease hippocampal expression of immune-related genes, and reduce expression of inflammatory cytokines such as TNF-α.

There is evidence for a link between inflammation and depression. Inflammatory processes can be triggered by negative cognitions or their consequences, such as stress, violence, or deprivation. Thus, negative cognitions can cause inflammation that can, in turn, lead to depression.

In addition there is increasing evidence that inflammation can cause depression because of the increase of cytokines, setting the brain into a "sickness mode". Classical symptoms of being physically sick like lethargy show a large overlap in behaviors that characterize depression. Levels of cytokines tend to increase sharply during depressive episodes in manics and drop off during remission. Furthermore, it has been shown in clinical trials that anti-inflammatory medicines taken in addition to antidepressants not only significantly improves symptoms but also increases the proportion of subjects positively responding to treatment.

Inflammations that lead to serious depression could be caused by common infections such as those caused by a virus, bacteria or even parasites.

Hyperalgesia is similar to other sorts of pain associated with nerve irritation or damage such as allodynia and neuropathic pain, and consequently may respond to standard treatment for these conditions, using various drugs such as SSRI or tricyclic antidepressants, Nonsteroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, gabapentin or pregabalin, NMDA antagonists, or atypical opioids such as tramadol. Where hyperalgesia has been produced by chronic high doses of opioids, reducing the dose may result in improved pain management. However, as with other forms of nerve dysfunction associated pain, treatment of hyperalgesia can be clinically challenging, and finding a suitable drug or drug combination that is effective for a particular patient may require trial and error. The use of a transcutaneous electrical nerve stimulation device has been shown to alleviate hyperalgesia.

Corticosteroids are administered through IV or orally. They cause lymphocytopenia, a condition where white blood cell levels are abnormally low. Corticosteroids cause white blood cell death, lowering their numbers throughout the body. They also cause white blood cells to recirculate away from the area of damage (the retina). This minimizes damage caused by the antibodies produced by the white blood cells. Often, this is treatment is combined with plasmapheresis. Instead of treating the plasma and blood cells, they are replaced with a healthy donor mixture. Patients who respond positively show improved visual fields and an almost complete disappearance of anti-retinal antibodies.

First-line treatment for CIDP is currently intravenous immunoglobulin (IVIG) and other treatments include corticosteroids (e.g. prednisone), and plasmapheresis (plasma exchange) which may be prescribed alone or in combination with an immunosuppressant drug. Recent controlled studies show subcutaneous immunoglobin (SCIG) appears to be as effective for CIDP treatment as IVIG in most patients, and with fewer systemic side effects.

IVIG and plasmapheresis have proven benefit in randomized, double-blind, placebo-controlled trials. Despite less definitive published evidence of efficacy, corticosteroids are considered standard therapies because of their long history of use and cost effectiveness. IVIG is probably the first-line CIDP treatment, but is extremely expensive. For example, in the U.S., a single 65 g dose of Gamunex brand in 2010 might be billed at the rate of $8,000 just for the immunoglobulin—not including other charges such as nurse administration. Gamunex brand IVIG is the only U.S. FDA approved treatment for CIDP, as in 2008 Talecris, the maker of Gamunex, received orphan drug status for this drug for the treatment of CIDP.

Immunosuppressive drugs are often of the cytotoxic (chemotherapy) class, including rituximab (Rituxan) which targets B cells, and cyclophosphamide, a drug which reduces the function of the immune system. Ciclosporin has also been used in CIDP but with less frequency as it is a newer approach. Ciclosporin is thought to bind to immunocompetent lymphocytes, especially T-lymphocytes.

Non-cytotoxic immunosuppressive treatments usually include the anti-rejection transplant drugs azathioprine (Imuran/Azoran) and mycophenolate mofetil (Cellcept). In the U.S., these drugs are used as "off-label" treatments for CIDP, meaning that their use here is accepted by the FDA, but that CIDP treatment is not explicitly indicated or approved in the drug literature. Before azathioprine is used, the patient should first have a blood test that ensures that azathioprine can safely be used.

Anti-thymocyte globulin (ATG), an immunosuppressive agent that selectively destroys T lymphocytes is being studied for use in CIDP. Anti-thymocyte globulin is the gamma globulin fraction of antiserum from animals that have been immunized against human thymocytes. It is a polyclonal antibody.

Although chemotherapeutic and immunosuppressive agents have shown to be effective in treating CIDP, significant evidence is lacking, mostly due to the heterogeneous nature of the disease in the patient population in addition to the lack of controlled trials.

A review of several treatments found that azathioprine, interferon alpha and methotrexate were not effective. Cyclophosphamide and rituximab seem to have some response. Mycophenolate mofetil may be of use in milder cases. Immunoglobulin and steroids are the first line choices for treatment. Rarely bone marrow transplantation has been performed.

Physical therapy and occupational therapy may improve muscle strength, activities of daily living, mobility, and minimize the shrinkage of muscles and tendons and distortions of the joints.

Antihistamine agents are the typically prescribed drug for the treatment of physical urticaria. They block the effect of histamine, a compound produced by the body which forms a part of the local immune response consequently causing inflammation. Some research has suggested that the use antihistamines and antagonist in synergy are better for the treatment of physical urticarias.

The cascade of events that link the autoantibody-antigen reaction with the production and release of histamine is not well characterized. Therefore, the focus of treatment for physical urticaria has been on characterizing the effectiveness of antihistamines rather than analysis of receptor binding or the pathomechanisms.

Plasmapheresis involves separating blood into two parts - blood cells and plasma. The blood plasma components, such as the antibodies, are treated outside of the body. After removal of the disease-associated antibodies, the blood cells and plasma are transfused back into the body. Response to this treatment depends on how much retinal damage has been done. Patients who respond positively show significant visual gains.

Inflammation is usually indicated by adding the suffix "", as shown below. However, some conditions such as asthma and pneumonia do not follow this convention. More examples are available at list of types of inflammation.

There are multiple large-field, multi-country research initiatives focusing on strategies to prevent and treat EE.

- The MAL-ED project

- The Alive and Thrive nutrition project

- The Sanitation, Hygiene and Infant Nutrition Efficacy (SHINE) Trial (ClinicalTrials.gov identifier: NCT01824940)

- The WASH Benefits Study

A low fat diet is indicated. The use of drugs which are known to have an association with pancreatitis should be avoided. Some patients benefit from the use of pancreatic enzymes on a supplemental basis. One study indicated that 57 percent of dogs, who were followed for six months after an acute pancreatitis attack, either continued to exhibit inflammation of the organ or had decreased acinar cell function, even though they had no pancreatitis symptoms.

Because neuroinflammation has been associated with a variety of neurodegenerative diseases, there is increasing interest to determine whether reducing inflammation will reverse neurodegeneration. Inhibiting inflammatory cytokines, such as IL-1β, decreases neuronal loss seen in neurodegenerative diseases. Current treatments for multiple sclerosis include interferon-B, Glatiramer actetate, and Mitoxantrone, which function by reducing or inhibiting T Cell activation, but have the side effect of systemic immunosuppression In Alzheimer's disease, the use of non-steroidal anti-inflammatory drugs decreases the risk of developing the disease. Current treatments for Alzheimer's disease include NSAIDs and glucocorticoids. NSAIDs function by blocking conversion of prostaglandin H2 into other prostaglandins (PGs) and thromboxane (TX). Prostoglandins and thromboxane act as inflammatory mediators and increase microvascular permeability.

Since each case is different, the following are possible treatments that patients might receive in the management of myelitis.

- Intravenous steroids

High-dose intravenous methyl-prednisolone for 3–5 days is considered as a standard of care for patients suspected to have acute myelitis, unless there are compelling reasons otherwise. The decision to offer continued steroids or add a new treatment is often based on the clinical course and MRI appearance at the end of 5 days of steroids.

- Plasma exchange (PLEX)

Patients with moderate to aggressive forms of disease who don’t show much improvement after being treated with intravenous and oral steroids will be treated with PLEX. Retrospective studies of patients with TM treated with IV steroids followed by PLEX showed a positive outcome. It also has been shown to be effective with other autoimmune or inflammatory central nervous system disorders. Particular benefit has been shown with patients who are in the acute or subacute stage of the myelitis showing active inflammation on MRI. However, because of the risks implied by the lumbar puncture procedure, this intervention is determined by the treating physician on a case-by-case basis.

- Immunosuppressants/Immunomodulatory agents

Myelitis with no definite cause seldom recurs, but for others, myelitis may be a manifestation of other diseases that are mentioned above. In these cases, ongoing treatment with medications that modulate or suppress the immune system may be necessary. Sometimes there is no specific treatment. Either way, aggressive rehabilitation and long-term symptom management are an integral part of the healthcare plan.

Peri-ocular injection of corticosteroids (injection of corticosteroids very close but not into the eye). In resistant cases oral administration of corticosteroids, immunosuppressive drugs, and laser or cryotherapy of the involved area may be indicated.

Steroid implants have been explored as a treatment option for individuals with non-infectious uveitis. Research comparing fluocinolone acetonide intravitreal implants to standard-of-care treatments (prednisolone with immunosuppressive agents) found that while the steroid implant treatment possibly prevents the recurrence of uveitis, there may be adverse safety outcomes, such as the increased risk for needing cataract surgery and surgery to lower intraocular pressure.

There are no approved treatments for canine pancreatitis. Treatment for this disease is supportive, and may require hospitialization to attend to the dog's nutritional and fluid needs, pain management, and addressing any other disease processes (infection, diabetes, etc.) while letting the pancreas heal on its own. Treatment often involves "resting" the pancreas for a short period of time by nil per os/nothing per os (NPO)/nil by mouth (NBM), in which the patient receives no food or fluids by mouth, but is fed and hydrated by intravenous fluids and a feeding tube. Dehydration is also managed by the use of fluid therapy. However, a specialist from Texas A&M University has stated "There is no evidence whatsoever that withholding food has any beneficial effect." Other specialists have agreed with his opinion.

Canine pancreatitis is complex, often limiting the ability to approach the disease.

Chronic pain is treated with a variety of medications and non-pharmacological interventions. Opioid tolerance and withdrawal can be seen in the NICU and PICU. Other side effects with opioid use can be: cognition deficits, altered mood, and disturbances of endocrine development. Opioid misuse can occur in adolescents and is associated with the use of alcohol, cigarettes and marijuana.

Non-pharmacological treatment for children in helping to relieve periodic pain episodes and severity includes counselling and behavior modification therapy. The American Association of Pediatrics have suggested that parents be educated on providing round the clock medication administration after their children receive surgery.

Treatments include class I topical steroids (clobetasol, halobetasol, etc.) which in some studies have proven to be equally effective as systemic, or pill, therapy and somewhat safer. However, in difficult-to-manage or widespread cases, systemic prednisone and powerful steroid-free immunosuppressant medications, such as methotrexate, azathioprine or mycophenolate mofetil, may be appropriate. Antibiotics such as tetracycline or erythromycin may also control the disease, particularly in patients who cannot use corticosteroids. The anti-CD20 monoclonal antibody rituximab has been found to be effective in treating some otherwise refractory cases of bullous pemphigoid.

IgA-mediated pemphigoid can often be difficult to treat even with usually effective medications such as rituximab.

The use of medications to treat acute, chronic, recurrent and neuropathic pain is most common. Most instances of pain in children are treated with analgesics. These include acetaminophen, NSAIDs, local anesthetics, opioids, and medications for neuropathic pain. The most effective approach to pain management in children is to provide medicine around the clock instead of providing pain relief as needed. Regional anesthesia is also effective and recommended whenever possible. Opioids are effective too but often depress breathing in infants.

The first-line therapy in ColdU, as recommended by EAACI/GA2 LEN/EDF/WAO guidelines, is symptomatic relief with second-generation H1- antihistamines. if standard doses are ineffective increasing up to 4-fold is recommended to control symptoms.

The second-generation H1-antihistamine, rupatadine, was found to significantly reduce the development of chronic cold urticaria symptom without an increase in adverse effects using 20 and 40 mg.

Allergy medications containing antihistamines such as diphenhydramine (Benadryl), cetirizine (Zyrtec), loratidine (Claritin), cyproheptadine (Periactin), and fexofenadine (Allegra) may be taken orally to prevent and relieve some of the hives (depending on the severity of the allergy). For those who have severe anaphylactic reactions, a prescribed medicine such as doxepin, which is taken daily, should help to prevent and/or lessen the likelihood of a reaction and thus, anaphylaxis. There are also topical antihistamine creams which are used to help relieve hives in other conditions, but there is not any documentation stating it will relieve hives induced by cold temperature.

Cold hives can result in a potentially serious, or even fatal, systemic reaction (anaphylactic shock). People with cold hives may have to carry an injectable form of epinephrine (like Epi-pen or Twinject) for use in the event of a serious reaction.

The best treatment for this allergy is avoiding exposure to cold temperature.

Studies have found that Omalizumab (Xolair) may be an effective and safe treatment to cold urticaria for patient who do not sufficiently respond to standard treatments.

Ebastine has been proposed as an approach to prevent acquired cold urticaria.
