　　Human Drug Overdose Experience: In the pre-market clinical trials of 5400 patients or normal subjects, 10 patients accidentally or intentionally overused ziprasidone.

One case of patients who had been confirmed to take the maximum dose of ziprasidone after marketing was reported. The dose was 12800 mg. Extrapyramidal symptoms and prolonged QTc interval reached 446 milliseconds, but did not. There are sequelae of heart. Overdose: once there is an acute excess, establish and maintain ventilation to ensure adequate oxygen. Can be intravenous infusion or gastric lavage, if the patient does not wake up, can poke the tube, after poking the tube gastric lavage, consider laxative and activated carbon use together.
