From the Research
Aciclovir treatment for pityriasis rosea is recommended for a duration of 7 days, with a typical regimen of oral aciclovir 800 mg five times daily, as this has been shown to reduce the duration and severity of symptoms in some studies 1. The use of aciclovir in treating pityriasis rosea is based on the association of human herpesvirus 6 and 7 with the disease, and some research suggests that antiviral agents may hasten recovery 2.
- The typical dose of aciclovir is 800 mg five times daily for 7 days, but some dermatologists may prescribe a lower dose of 400 mg three times daily for 7-10 days, especially for less severe cases 3.
- Treatment should ideally begin early in the course of the disease, preferably within the first week of symptom onset, as this appears to provide better results 1.
- Aciclovir may help reduce the duration and severity of symptoms by targeting human herpesvirus 6 and 7, which some research suggests may be associated with pityriasis rosea 4.
- Patients should be informed that even with treatment, the rash typically resolves on its own within 6-8 weeks 2.
- Side effects of aciclovir may include nausea, headache, and dizziness, and it's essential to maintain adequate hydration while taking this medication 5.
- For symptomatic relief of itching, topical treatments like calamine lotion or mild corticosteroids and antihistamines may be used alongside aciclovir 3.
