Introduction: Loxoscelism represents a major public health problem for which there are no standard thera-peutic interventions. Objective: To review available scientific evidence on management of Loxoscelism Method: Systematic review of clinical studies. The search included múltiple databases (Medline, Lilacs, Embase, Web of Sciences, Cinahl, Pre-Cinahl, Paperfirst, Proceedingsfirst, Dissertations and Theses, Toxline, Cochrane Library), handsearch of references, and contact with experts. Results: Three clinical triáis of poor methodological quality were identified from 5,207 references found. One trial (n = 31), concluded that the use of dapsone was associated with fewer local complications than surgical treatment. A second study (n = 46), concluded that the use of dapsone was superior to clorfenamine for skin lesions. A third study (n = 95) concluded that there was no differences be-tween the use of oral dapsone, antivenom against anti-Loxosceles reclusa or a combination of both. Conclusions: There is insufficient evidence based on good quality studies to recommend treatment guidelines for individuáis with skin or visceral loxoscelism.
