    ### Response:
    How might pityriasis rubra pilaris be treated? Treatment of pityriasis rubra pilaris (PRP) is mainly based on reports of patients' experiences. No controlled trials have been done, so the effectiveness and safety of treatments is unclear. Currently there are no treatments approved by the US Food and Drug Administration (FDA) or the European Medicines Agency (EMA) for use in PRP.
