How long does pityriasis rosea last?
Pityriasis rosea usually lasts 1 to 3 months and usually never comes back. Let your doctor know if the rash or itching lasts longer than 3 months.
How is pityriasis rosea treated?
The rash usually goes away on its own. No treatment can cure it, but medicine can help relieve the itching. Your doctor might suggest antihistamine pills (one brand name: Benadryl), a steroid cream, calamine lotion or zinc oxide cream to relieve the itching. Sometimes people who have pityriasis rosea have to take steroid pills to clear up their rash.
