In brief: Pityriasis treatments need more evidence

Inadequate evidence exists on the efficacy of most treatments for pityriasis rosea, a Cochrane review has concluded. Only three trials involving a total of 148 people fitted the researchers' criteria for inclusion in the review. They state that oral erythromycin may be effective for treating the rash and reducing itch, but say that this result needs to be treated with caution because it comes from only one small randomised controlled trial.
