Pityriasis rosea typically doesn't require treatment as it usually resolves on its own within 6-12 weeks. For symptom relief, over-the-counter antihistamines like diphenhydramine (25-50mg every 4-6 hours) or cetirizine (10mg daily) can help reduce itching 1. Topical corticosteroids such as hydrocortisone 1% cream applied twice daily to affected areas may also alleviate itchiness. Lukewarm baths with colloidal oatmeal can soothe the skin. For severe cases, a dermatologist might prescribe stronger corticosteroids, oral antihistamines, or occasionally UVB phototherapy. Some key points to consider in the treatment of pityriasis rosea include:
- The condition is self-limiting and usually resolves without treatment 2
- Symptomatic treatment is the primary approach, focusing on relieving itching and discomfort 3
- Oral acyclovir may be considered for severe cases, as it has been shown to reduce the duration of illness 2
- Macrolide antibiotics like erythromycin may be effective in reducing itch, but the evidence is limited 1
- Keeping the skin moisturized with fragrance-free lotions and avoiding hot showers can help prevent further irritation. It's essential to note that the condition is believed to be triggered by a viral infection, particularly human herpesvirus 6 and 7, which explains why it's self-limiting and why symptomatic treatment is the primary approach 4.
