In the present study, we describe the clinical and demographical characteristics of acute methadone toxicity in a cohort of pediatric poisoned patients in Isfahan, Iran and discussed the predictive factors for their treatment outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>In this 4-year cross-sectional study which was performed from 2013 to 2016 in a referral university hospital (Isfahan, Iran), medical records of the demographic and admission time clinical characteristics of all in-patients aged &lt;18 years with acute methadone poisoning were abstracted and analyzed. According to the outcomes of hospital care and treatment, patients were divided as survived without medical complication and patients survived with at least one medical complication or death.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings:<\/jats:title>\n                    <jats:p>A total number of 157 (79 male) children and adolescents with a mean age of 105.4 \u00b1 6.1 months were hospitalized and included in the study. A total of 145 (92.4%) patients survived and discharged from the hospital without any medical complication.
