Demographic information, details of ingestion, clinical effects, ECG parameters (HR, QT and QRS), and length of stay were extracted from a clinical database. Results: From 267 mirtazapine overdoses, there were 89 single-agent mirtazapine ingestions and 178 cases where mirtazapine was taken with at least one other drug. The median age of the 89 single-agent mirtazapine ingestions was 36 years [interquartile range (IQR): 26 – 49 years; Range: 15 – 81 years]; 45 were female (51%). The median ingested dose was 420 mg (IQR: 270 – 750 mg; Range: 150 – 1350 mg) and 41 patients (46%) had a Glasgow coma score (GCS) < 15, but the minimum GCS was 10. There were no seizures, serotonin toxicity or delirium. Tachycardia occurred in 29 patients (33%) and hypertension in 32 patients (36%). The median QRS was 80 ms (Range: 80 – 120 ms) and there were no cases with QT prolongation. There were no arrhythmias and no deaths. The median length of stay was 14 h (IQR: 8.8 – 18.2 h; Range:2.2 – 75 h). No single-agent mirtazapine patient was admitted to intensive care. The 178 patients taking co-ingestants had more severe toxicity depending on the co-ingested drug. Conclusion: Mirtazapine appears to be relatively benign in overdose, associated with tachycardia, mild hypertension and mild CNS depression not requiring intervention.]]> Sat 24 Mar 2018 08:19:18 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45743 Fri 04 Nov 2022 10:12:56 AEDT ]]>
