Antibiotics

Antibiotics to treat skin infections may be applied directly to the skin in an ointment, but are usually more effective when taken by mouth. If viral or fungal infections are present, the doctor may also prescribe specific medications to treat those infections.

Certain antihistamines that cause drowsiness can reduce nighttime scratching and allow more restful sleep when taken at bedtime. This effect can be particularly helpful for patients whose nighttime scratching makes the disease worse.

In adults, drugs that suppress the immune system, such as cyclosporine, methotrexate, or azathioprine, may be prescribed to treat severe cases of atopic dermatitis that have failed to respond to other forms of therapy. These drugs block the production of some immune cells and curb the action of others. The side effects of drugs like cyclosporine can include high blood pressure, nausea, vomiting, kidney problems, headaches, tingling or numbness, and a possible increased risk of cancer and infections. There is also a risk of relapse after the drug is stopped. Because of their toxic side effects, systemic corticosteroids and immunosuppressive drugs are used only in severe cases and then for as short a period of time as possible. Patients requiring systemic corticosteroids should be referred to dermatologists or allergists specializing in the care of atopic dermatitis to help identify trigger factors and alternative therapies.

In rare cases, when home-based treatments have been unsuccessful, a patient may need a few days in the hospital for intense treatment.

Phototherapy: Use of ultraviolet A or B light waves, alone or combined, can be an effective treatment for mild to moderate dermatitis in older children (over 12 years old) and adults. A combination of ultraviolet light therapy and a drug called psoralen can also be used in cases that are resistant to ultraviolet light alone. Possible long-term side effects of this treatment include premature skin aging and skin cancer. If the doctor thinks that phototherapy may be useful to treat the symptoms of atopic dermatitis, he or she will use the minimum exposure necessary and monitor the skin carefully.
