"Conclusion
MDMA toxicity frequently has favorable outcomes with relatively limited intervention, but severe episodes of toxicity or overdose can lead to marked neurologic, hepatic, or cardiovascular damage. Due to the frequently limited and unreliable histories common to this type of ingestion, serial evaluations of these patients are recommended to ensure initial interventions are progressing appropriately and that no new findings are discovered. Through close monitoring and timely intervention, it is possible to minimize the morbidity and mortality associated with MDMA use."
