Most of the time pityriasis rosea will resolve on its own without any treatment within eight to ten weeks but there are some treatments that can be done to help make you feel more comfortable. In stage two your dermatologist may give you some creams to help soothe the symptoms, especially the itchiness. Your dermatologist may have you use over-the-counter or give you a prescription for topical steroid creams like hydrocortisone cream and anti-itch medications like calamine lotion. Soaking in a soothing oatmeal bath can also help with not only the itching but can also lift away the dead skin. You should keep from scratching or picking at the areas because this can cause your skin to open up and create lesions where you can let bacteria into your body. It can also lead to scars developing. Do not use soap that contains alcohol because these can dry out your skin.
Pityriasis rosea is a self-limiting rash that can occur both in adults and in children. Pityriasis rosea is more common in children and young adults. It is most common in people aged between 10 and 35 years. It is more common in the spring and autumn months.
Its exact cause is unknown. No germ (bacterium, virus, or fungus) has been found in people with the rash. However, certain types of human herpes viruses may be a part of the cause. It is not associated with food, medicines or stress. However, some medicines can cause a rash which looks similar to pityriasis rosea.
