There are no treatments that cure pityriasis rosea; the disease must run its course. However, itching, if present, can be treated in several ways. An over-the-counter a lotion that cools the skin (such as one with camphor or menthol) or corticosteroid cream (such as Cortizone-10 or Cortaid) may be enough to provide relief. For more severe itching, oral antihistamines may be prescribed.
In very severe cases in which the rash lasts longer than usual, or if the rash covers a large part of the body, ultraviolet (UV) light therapy may be recommended. Doses of UV-B rays, similar to the sun's rays, are given by exposing the skin to the light rays for short periods of time over several days. The skin may turn slightly red, similar to a mild sunburn.
The red spots may appear more prominently after a hot shower or bath and after heavy physical activity. The condition doesn't get worse. The rash simply becomes more noticeable.
