Treatment involves avoiding things that make it worse, daily bathing with application of a moisturising cream afterwards, applying steroid creams when flares occur, and medications to help with itchiness.[2] Things that commonly make it worse include wool clothing, soaps, perfumes, chlorine, dust, and cigarette smoke. Phototherapy may be useful in some people. Steroid pills may occasionally be used if other measures are not effective.[1] Antibiotics (either by mouth or topically) may be needed if a bacterial infection develops.[2] Dietary changes are only needed if food allergies are suspected.[1]
