Pityriasis Rosea: Care Instructions

Your Care Instructions

Pityriasis rosea (say "pit-uh-RY-uh-sus ROH-zee-uh") is a common skin rash. It usually starts as one scaly, reddish-pink spot on your stomach or back. Days or weeks later, more spots appear. The rash may itch, but it will not spread to other people.

No one knows what causes pityriasis rosea. Some doctors believe it is a reaction to a virus.

Pityriasis rosea is most common in children and young adults. It lasts 1 to 3 months and then goes away on its own. Medicine can help relieve any itching.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Use your medicine exactly as prescribed. Call your doctor or nurse advice line if you have any problems with your medicine.
  • Expose your skin to small amounts of sunlight, but avoid sunburn. Sunlight can lessen the rash.
  • Use a mild soap, such as Dove or Cetaphil, when you wash your skin.
  • Add a handful of oatmeal (ground to a powder) to your bath. Or you can try an oatmeal bath product, such as Aveeno. Keep the water warm or lukewarm. A hot bath or shower may make the rash more visible and itchy.
  • Use an over-the-counter hydrocortisone cream for small itchy areas.

When should you call for help?

Call your doctor or nurse advice line now or seek immediate medical care if:

  • You have signs of infection such as :
    • Pain, warmth, or swelling near the rash.
    • Red streaks near the rash.
    • Pus coming from the rash.
    • A fever.

Watch closely for changes in your health, and be sure to contact your doctor or nurse advice line if:

  • You see the rash on the palms of your hands or the soles of your feet.
  • You do not get better as expected.
