Treatment
Treatment with emollients is used to relieve symptoms of cracking and dryness. Application of lubricants under plastic occlusion before bedtime appears to aid removal of scales on hands and feet. Other topical options include: topical corticosteroids alone, or combined with keratolytics, such as urea and vitamin D3 analogues. The most effective therapy is long term use of oral retinoids, such as acitretin and isotretinoin. Other effective systemic approaches include: methotrexate, cyclosporin and corticosteroids. There are also reports that the monoclonal antibody ustekinumab (which blocks IL-23/ IL-12) may be effective. See also
