Pityriasis Rosea

Pityriasis rosea is a relatively common skin condition that causes a temporary rash of raised red scaly patches on the body. It can affect anyone, but it's more common in older children and young adults (aged 10 to 35). It's not known what causes pityriasis rosea. One theory is that the rash may be caused by a viral infection.

Pityriasis rosea is not contagious and cannot be spread to other people through physical contact.

  • Treatment
  • See your doctor if you have an unexplained rash. They'll usually be able to confirm whether it's pityriasis rosea, or another skin condition such as eczema, psoriasis or ringworm. Pityriasis rosea usually gets better without treatment within 12 weeks. Treatment is not needed unless you experience discomfort and itching. Possible treatments for pityriasis rosea include: 1-Emollients – creams that moisturise and soothe the skin. 2-Steroid creams or ointments – such as hydrocortisone and betamethasone cream. 3-Antihistamines – if you're having trouble sleeping because of the itching, a GP may prescribe an antihistamine that will make you feel sleepy, such as hydroxyzine or chlorpheniramine. 4-UVB light therapy – if other treatments do not work, you may be referred for UVB light therapy
