In general, pityriasis rosea resolves within 12 weeks, and no follow-up is necessary in most cases. However, follow-up care may be provided to ensure that the rash is improving. Patients with moderate to severe pruritus who are receiving topical steroids should be followed up by phone or at a return visit in 1-2 weeks.
If the disease is severe or widespread (eg, vesicular pityriasis rosea), topical or oral steroids may be used. Ultraviolet radiation therapy has been demonstrated to be effective for pityriasis rosea but may leave postinflammatory pigmentation at the site of the pityriasis rosea lesion.
No restriction of activity or isolation is necessary. No evidence suggests that children with pityriasis rosea should be prevented from attending school.
