“…The most important part of treatment is to inform the patient that skin irritation, such as caused by vigorous washing, can trigger eczema and delay healing. In difficult‐to‐treat disease, a combination of mild topical glucocorticoids and low‐dose UVB radiation (for patients aged 12 years and older) may be considered [11]. Some authors also have reported the effective use of antibiotics (erythromycin [12]) and antiviral drugs (administration of acyclovir within a week of disease onset) [13].…”

Pityriasis rosea: An important papulosquamous disorder

“…The duration of the disease before phototherapy does not affect the outcome 105 . Broadband UVB therapy in PR patients may substantially decrease the severity of the disease, sometimes leading to total recovery 106 . A direct relationship may exist between the duration of PR before treatment and the number of UVB procedures required 106,107 .…”

“…Broadband UVB therapy in PR patients may substantially decrease the severity of the disease, sometimes leading to total recovery 106 . A direct relationship may exist between the duration of PR before treatment and the number of UVB procedures required 106,107 . Lesions on the lower extremities may be more resistant to this form of therapy 106 .…”

Characterizing Viral Exanthems

“…There is some evidence for narrow-band ultraviolet-B phototherapy [76,77]. Topical steroids may be used for associated pruritus [78].…”
