The use of antivirals in severe or recalcitrant cases of pityriasis rosea: A case series

What’s old is new: Valacyclovir for the treatment of pityriasis rosea, a retrospective case series

“…12 The efficacy of valacyclovir as treatment for PR has so far been reported in 1 case series of 3 patients: while watchful waiting led to worsening symptoms, treatment with valacyclovir 1 g 3 times daily for 1 week led to resolution of the condition within 2 to 3 weeks. 13 The authors have proposed valacyclovir as an alternative therapeutic option due to its less frequent dosing and a more favorable safety profile when compared with those of acyclovir. The dosing schedule of valacyclovir used in this series was adapted from the established treatment regimen for herpes zoster infection (shingles), which consists of oral valacyclovir 1 g 3 times daily for 7 days, which is the standard dose without renal adjustment.…”
