Herein, we report a case of emergency cesarean section after severe maternal drug intoxication in late pregnancy. At a 38-week-gestation, a 32-year-old woman with a 10-year history of bipolar disorder took olanzapine (200 mg), diazepam (20 mg), and zolpidem (200 mg) as part of a suicidal attempt. Given her unconscious state and the evident concern regarding the toxic effects of the drugs on the fetus, a cesarean section was performed immediately. The patient gave birth to a male baby with Apgar scores of 5 at 1 and 8 at 5 minutes. The baby showed dyspnea and decreased activity directly after birth. After supportive care, the condition of both mother and baby improved and both were discharged.
