If symptoms are well controlled with moisturizers, steroids may only be required when flares occur. Corticosteroids are effective in controlling and suppressing symptoms in most cases. Once daily use is generally enough. For mild-moderate eczema a weak steroid may be used (e.g., hydrocortisone), while in more severe cases a higher-potency steroid (e.g., clobetasol propionate) may be used. In severe cases, oral or injectable corticosteroids may be used. While these usually bring about rapid improvements, they have greater side effects.

Long term use of topical steroids may result in skin atrophy, stria, telangiectasia. Their use on delicate skin (face or groin) is therefore typically with caution. They are, however, generally well tolerated. Red burning skin, where the skin turns red upon stopping steroid use, has been reported among adults who use topical steroids at least daily for more than a year.

Oatmeal contains avenanthramide (anthranilic acid amides), which can have an anti-inflammatory effect.

Topical corticosteroids, such as hydrocortisone have proven themselves effective in managing AD. If topical corticosteroids and moisturisers fail, short-term treatment with topical calcineurin inhibitors like tacrolimus or pimecrolimus may be tried, although they are usually avoided as they can increase the risk of developing skin cancer or lymphoma. Alternatively systemic immunosuppressants may be tried such as ciclosporin, methotrexate, interferon gamma-1b, mycophenolate mofetil and azathioprine. Antidepressants and naltrexone may be used to control pruritus (itchiness). In 2016 crisaborole was approved as a topical treatment for mild-to-moderate eczema. In 2017, the biologic agent dupilumab was approved to treat moderate-to-severe eczema.

Dapsone is an effective treatment in most people. Itching is typically reduced within 2–3 days. However, dapsone treatment has no effect on any intestinal damage that might be present.

Therefore, a strict gluten-free diet must also be followed, and this will usually be a lifelong requirement. This will reduce any associated intestinal damage and the risk of other complications. After some time on a gluten-free diet, the dosage of dapsone can usually be reduced or even stopped, although this can take many years.

Dapsone is an antibacterial, and its role in the treatment of DH, which is not caused by bacteria, is poorly understood. It can cause adverse effects on the blood, so regular blood monitoring is required.

Dapsone is the drug of choice. For individuals with DH unable to tolerate dapsone for any reason, alternative treatment options may include the following:

- colchicine

- lymecycline

- nicotinamide

- tetracycline

- sulfamethoxypyridazine

- sulfapyridine

A more novel form of treatment involves exposure to broad or narrow-band ultraviolet (UV) light. UV radiation exposure has been found to have a localized immunomodulatory effect on affected tissues and may be used to decrease the severity and frequency of flares. In particular, the usage of UVA1 is more effective in treating acute flares, whereas narrow-band UVB is more effective in long-term management scenarios. However, UV radiation has also been implicated in various types of skin cancer, and thus UV treatment is not without risk.

If the rash does not improve or continues to spread after 2–3 of days of self-care, or if the itching and/or pain is severe, the patient should contact a dermatologist or other physician. Medical treatment usually consists of lotions, creams, or oral medications.

- Corticosteroids. A corticosteroid medication similar to hydrocortisone may be prescribed to combat inflammation in a localized area. It may be applied to the skin as a cream or ointment. If the reaction covers a relatively large portion of the skin or is severe, a corticosteroid in pill or injection form may be prescribed.

In severe cases, a stronger medicine like halobetasol may be prescribed by a dermatologist.

- Antihistamines. Prescription antihistamines may be given if non-prescription strengths are inadequate.

A number of medications speed up recovery including: tetracycline, doxycycline, and erythromycin. Erythromycin may be used as a cream. Doxycycline is most often the first antibiotic drug choice, given at a daily dosage of 100 mg for upto a month before considering tapering off or stopping. Sometimes, longer duration of low doses of doxycycline are required.

Metronidazole is less effective, is available in a gel and can be applied twice daily. If the perioral dermatitis was triggered by a topical steroid then pimecrolimus cream has been suggested as effective in improving symptoms. However, this has also been documented to cause the condition.

Multiple treatment regimes are available and treatment algorithms have been proposed.

Perioral dermatitis will usually resolve within a few months without medication and by limiting the use of cosmetics. This is called zero treatment. Topical corticosteroids should be stopped entirely if possible. If the flare proves intolerable, temporary use of a less potent topical corticosteroid can often be helpful.

The clinical expression of the dermatitis can be mitigated by avoidance of the allergen. Through compliance with avoidance measures, the immune system can become less stimulated. The key to avoidance is proper evaluation and detection of the inciting allergen. However, once the immune system registers the allergen, the recognition is permanent.

The first step in treating the condition is appropriate recognition of the clinical problem, followed by identification of the culprit chemical and the source of that chemical. Corticosteroid creams should be used carefully and according to the prescribed directions because when overused over longer periods of time they can cause thinning of the skin. Also, in some instances such as poison ivy dermatitis calamine lotion and cool oatmeal baths may relieve itching.

Usually, severe cases are treated with systemic corticosteroids which may be tapered gradually, with various dosing schedules ranging from a total of 12 – 20 days to prevent the recurrence of the rash (while the chemical allergen is still in the skin, up to 3 weeks, as well as a topical corticosteroid. Tacrolimus ointment or pimecrolimus cream can also be used additionally to the corticosteroid creams or instead of these. Oral antihistamines such as diphenhydramine or hydroxyzine may also be used in more severe cases to relieve the intense itching. Topical antihistamines are not advised as there might be a second skin reaction (treatment associated contact dermatitis) from the lotion itself.

The other symptoms caused by allergic contact dermatitis may be eased with cool compresses to stop the itching. It is vital for treatment success that the trigger be identified and avoided. The discomfort caused by the symptoms may be relieved by wearing smooth-textured cotton clothing to avoid frictional skin irritation or by avoiding soaps with perfumes and dyes.

Commonly, the symptoms may resolve without treatment in 2 to 4 weeks but specific medication may hasten the healing as long as the trigger is avoided. Also, the condition might become chronic if the allergen is not detected and avoided.

One of the keys to treatment and prevention involves keeping the skin moisturized. Lotions, creams, and bath oils may help prevent an outbreak. If the condition flares up, a common treatment involves the application of topical corticosteroids. Oral antihistamines may help lessen itching. Avoidance of irritants is a common strategy. More severe cases sometimes respond to ultraviolet light treatment.

Id reactions are frequently unresponsive to corticosteroid therapy, but clear when the focus of infection or infestation is treated. Therefore, the best treatment is to treat the provoking trigger. Sometimes medications are used to relieve symptoms.These include topical corticosteroids, and antihistamines. If opportunistic bacterial infection occurs, antibiotics may be required.

All of these drugs may cause severe side effects, so the patient should be closely monitored by doctors. Once the outbreaks are under control, dosage is often reduced, to lessen side effects.

If skin lesions do become infected, antibiotics may be prescribed. Tetracycline antibiotics have a mildly beneficial effect on the disease and are sometimes enough for Pemphigus Foliaceus. In addition, talcum powder is helpful to prevent oozing sores from adhering to bedsheets and clothes. Wound care and treatment is often akin to that used in burn units, including careful use of dressings that don't stick to the wounds, etc.

If paraneoplastic pemphigus is diagnosed with pulmonary disease, a powerful cocktail of immune suppressant drugs is sometimes used in an attempt to halt the rapid progression of bronchiolitis obliterans, including methylprednisolone, ciclosporin, azathioprine, and thalidomide. Plasmapheresis may also be useful.

If not treated, pemphigus can be fatal, usually from overwhelming opportunistic infection of lesions. The most common treatment is the administration of oral steroids, especially prednisone, often in high doses. The side effects of corticosteroids may require the use of so-called steroid-sparing or adjuvant drugs. One of the most dangerous side effects of high dosage steroid treatments is intestinal perforations, which may lead to sepsis. Steroids and other medications being taken to treat Pemphigus may also mask the effects of the perforations. Patients on high dosages of oral steroids should closely monitor their GI health. As lesions are usually terribly painful, it is likely that pain medication can complicate and exacerbate the GI issues caused by steroids.

In an industrial setting the employer has a duty of care to its worker to provide the correct level of safety equipment to mitigate exposure to harmful irritants. This can take the form of protective clothing, gloves, or barrier cream, depending on the working environment.

Topical antibiotics should not be used to prevent infection in wounds after surgery. When they are used, it is inappropriate, and the person recovering from surgery is at significantly increased risk of developing contact dermatitis.

A full recovery is expected with treatment. Recurrent id reactions are frequently due to inadequate treatment of the primary infection or dermatitis and often the cause of recurrence is unknown.

You have to treat the primary cause or the exacerbation may persisist and reincide.

Topical steroids are the primary category of medications used to treat exfoliative dermatitis (ED). A sedative antihistamine may be a useful adjunct for pruritic patients, since it helps patients to sleep at night, thus limiting nocturnal scratching and excoriations. Antimicrobial agents often are used if an infection is suspected to be precipitating or complicating exfoliative dermatitis. Other drugs specifically indicated for management of underlying cause of exfoliative dermatitis may be necessary.

Dermatitis herpetiformis generally responds well to medication and changes in diet. However, it is an autoimmune disease, and patients with DH are more likely than others to have thyroid problems and intestinal lymphoma.

Dermatitis herpetiformis does not usually cause complications on its own, without being associated with another condition. Complications from this condition, however, arise from the autoimmune character of the disease, as an overreacting immune system is a sign that something does not work well and might cause problems to other parts of the body that do not necessarily involve the digestive system.

Gluten intolerance and the body's reaction to it make the disease more worrying in what concerns the possible complications. This means that complications that may arise from dermatitis herpetiformis are the same as those resulting from coeliac disease, which include osteoporosis, certain kinds of gut cancer, and an increased risk of other autoimmune diseases such as thyroid disease.

The risks of developing complications from dermatitis herpetiformis decrease significantly if the affected individuals follow a gluten-free diet. The disease has been associated with autoimmune thyroid disease, insulin-dependent diabetes, lupus erythematosus, Sjögren's syndrome, sarcoidosis, vitiligo, and alopecia areata.

In persistent or especially bad rashes, an antifungal cream often has to be used. In cases that the rash is more of an irritation, a "mild" topical corticosteroid preparation, e.g. hydrocortisone cream, is used. As it is often difficult to tell a fungal infection apart from a mere skin irritation, many physicians prefer an corticosteroid-and-antifungal combination cream such as hydrocortisone/miconazole.

Various moisture-absorbing powders, such as talcum or starch, reduce moisture but may introduce other complications. Airborne powders of any sort can irritate lung tissue, and powders made from starchy plants (corn, arrowroot) provide food for fungi and are not recommended by the American Academy of Dermatology.

Prevention measures include avoidance of the irritant through its removal from the workplace or through technical shielding by the use of potent irritants in closed systems or automation, irritant replacement or removal and personal protection of the workers.

Antihistamines are used primarily to reduce itching, if present. However, research studies suggest that some antihistamines have anti-inflammatory properties.

A number of medications are able to control seborrheic dermatitis including: certain antifungals, topical corticosteroids, and keratolytics such as topical urea, as well as antiandrogens and antihistamines.

Treatment may include corticoids, astringents, and keratolytics. Dermatoses tend to be recurrent unless the use or contact can be avoided. Discontinuation of the instrument is curative in almost all cases, but usually impractical.

The aim of treatment is to relieve the allergy-induced itch and to remove the fleas from the pet and its home environment. In some cases, secondary bacterial or yeast infections will also need treatment before the itching subsides. Environmental flea control includes using flea foggers or bombs, vacuuming, and treating pet bedding by washing on a hot cycle (over 60 degrees Celsius) in the washing machine. The current on-pet treatment recommended by veterinary dermatologists is spinosad (Comfortis) monthly and nitenpyram (Capstar or generics) every 48 hours until improvement.

Many pets with FAD may also have other allergies, such as allergies to food, contact allergies, and atopic dermatitis.

Generous application of bland emollients can improve the rash. However, complete resolution will not occur until the lip licking stops. Breaking the cycle of dryness then licking followed by more dryness is key to treatment. Sometimes, unlike in perioral dermatitis, topical steroids may be used for few days only.
