It's unclear which treatment is best, because there have been no head-to-head comparisons of treatments for Rhus (plant-induced) contact dermatitis. That said, topical high-potency steroids slightly improve pruritus and the appearance of the rash (strength of recommendation [SOR]: B, small cohort studies). Neither topical pimecrolimus (an immunomodulatory drug) nor jewelweed extract are helpful (SOR: B, 1 small randomized controlled trial [RCT]). Oral steroids improve symptoms in severe cases (SOR: C, expert opinion)
