Pityriasis Rosea Q & A

What is pityriasis rosea?

Pityriasis rosea is a type of skin rash. Researchers are still investigating what causes this rash, but it’s theorized it may be related to the human herpes virus, a variety of viral infections.

The human herpes virus is common, and there are many strains of the virus. These groups of viruses cause cold sores and genital herpes. In most people who carry the virus, the immune system works well at preventing any type of outbreak.

It’s believed that a strain of the human herpesvirus causes pityriasis rosea, but the rash only appears when you have a weakened immune system, like during pregnancy.

This rash isn’t contagious, but it’s not uncommon for more than one member of the household to have pityriasis rosea at the same time.

What are the symptoms of pityriasis rosea?

The first sign of pityriasis rosea is the appearance of a large raised oval rash on your abdomen, chest, or back. Known as a herald patch, this circular rash can be up to 4 inches in diameter.

A few days or weeks after the first herald patch, you may develop additional smaller scaly spots. Pityriasis rosea can be itchy. The rash might continue to spread over the next week or two.

Once it stops spreading, pityriasis rosea may last a few months.


If you have these symptoms, schedule an appointment at Houston Skin Associates. Though pityriasis rosea is harmless, it’s important to get the right diagnosis.

What happens during a pityriasis rosea evaluation?

The Houston Skin Associates team conducts a patient-centered exam when you come in with concerns about a skin rash. They review your symptoms and medical history and examine your rash.

The skilled dermatologists can diagnose pityriasis rosea after a physical but may take a skin biopsy of your rash to confirm their findings.

How is pityriasis rosea treated?

Houston Skin Associates customizes treatment for pityriasis rosea based on the severity of your symptoms. The skin rash typically goes away without treatment, but you may benefit from medications to ease itching.

Your dermatologist may recommend a hydrocortisone cream or an antihistamine; they may also prescribe an antiviral medication.
