Occasionally, anti-inflammatory medications such as corticosteroid may be necessary to stop itching or make the rash go away. Patients should be reassured that this disease is not a dangerous skin condition even if it occurs during pregnancy.

  1. Although there is no cure for pityriasis rosea, in most cases the condition goes away by itself without any treatment. Ultraviolet light treatment or phototherapy may shorten the duration of the condition and may be prescribed for extensive and persistent cases of pityriasis. Corticosteroid creams may also be prescribed to relieve the itching.
  2. Pityriasis rosea usually lasts between 6 to 12 weeks — the rashes disappear without scarring. In people with dark complexions, however, hyperpigmented discolorations may last for several months afterwards.
  3. Although Pityriasis rosea may occur in more than one person in a household at a time, it is not thought to be highly contagious.
