The application of skin moisturizers is not only the initial treatment for patients with AD, it is also an integral part of maintenance therapy and the prevention of disease flare-ups. Effective emollients for AD are available in both nonprescription and prescription formulations.

An effective treatment method to improve skin hydration is to recommend that patients take 5-minute lukewarm baths and apply an emollient immediately thereafter, while skin is wet, to seal in the moisture.

Topical corticosteroid ointments are initiated after symptoms of AD continue if the use of skin moisturizers does not provide adequate control. If nonprescription topical corticosteroid creams or ointments prove ineffective, physicians may prescribe a low-potency (Class VI or VII in mild cases) or intermediate-potency (Class III, IV, or V in moderate cases) topical steroid cream or ointment. Only low-potency topical steroids should be used on the face, axillae, groin, and intertriginous areas due to increased absorption and a greater potential for local steroid adverse effects.

Dupilumab, a monoclonal antibody that inhibits interleukin (IL)-4 and IL-13, has been approved by the US Food and Drug Administration to treat AD. Dupilumab is indicated for patients aged 6 years and older with moderate to severe AD not adequately controlled with topical therapies or when those therapies are not advisable. Dupilumab may also have an ameliorative effect on asthma and other allergic disorders. Trials involving lebrikizumab and tralokinumab (which selectively target IL-13) and nemolizumab (targeting IL-31) hold promise in the treatment of this challenging condition. Additionally, topical and systemic Janus kinase inhibitors are being investigated for use in AD.

Immunomodulatory medications, such as tacrolimus ointment 0.1% for adults or 0.03% for children and pimecrolimus 1% cream, are approved for use in patients with moderate to severe AD. These calcineurin inhibitors are second-line therapy and are currently under a black box warning in the United States due to the potential risk for the development of malignancies, although this association remains unclear.

Crisaborole ointment 2% is a phosphodiesterase-4 inhibitor that is approved for use in patients with mild to moderate AD.
