What are the causes of Pityriasis Rosea?

Pityriasis rosea is believed to be caused by a virus. It occurs most often in the fall and spring.

Although pityriasis rosea may occur in more than one person in a household at a time, it is not thought to spread from one person to another. Females seem to be more affected than males.

What are the symptoms of Pityriasis Rosea?

Attacks most often last 4 to 8 weeks. Symptoms may disappear by 3 weeks or last as long as 12 weeks.

The rash starts with a single large patch called a herald patch. After several days, more skin rashes will appear on the chest, back, arms, and legs.

The skin rashes:

  • Are often pink or pale red
  • Are oval in shape
  • May be scaly
  • May follow lines in the skin or appear in a "Christmas tree" pattern
  • May itch

Other symptoms may include:

  • Headache
  • Fatigue
  • Sore throat
  • Mild fever

What are the current treatments for Pityriasis Rosea?

If symptoms are mild, you may not need treatment.

Your provider may suggest gentle bathing, mild lubricants or creams, or mild hydrocortisone creams to soothe your skin.

Antihistamines taken by mouth may be used to reduce itching. You can buy antihistamines at the store without a prescription.

Moderate sun exposure or ultraviolet (UV) light treatment may help make the rash go away more quickly. However, you must be careful to avoid sunburn.
