Published: May 2018

Among atypical antipsychotics, quetiapine is commonly prescribed and considered to have a favorable side effect and safety profile. Here, we report the case of a patient who developed a generalized tonic-clonic seizure 28 hours following ingestion of 1,400 mg of quetiapine. Review of the literature identifies delayed-onset seizure as a potential complication of quetiapine overdose. Unique to this case, delayed-onset seizures occurred in a patient with a relatively low dose of quetiapine and no obvious toxidrome, suggesting that this reaction may be an important consideration in the management of quetiapine overdose. The pharmacokinetics and pharmacodynamics of quetiapine may explain this unusual phenomenon.

Article Synopsis
  • * A case report describes a 40-year-old man who developed NMS after withdrawing from venlafaxine while taking a low dose of quetiapine, suggesting that withdrawal may be a contributing factor in NMS cases.
  • * This case highlights the importance of recognizing the risk of NMS even at low doses of quetiapine in patients without known risk factors, emphasizing the need for careful monitoring and prompt diagnosis.

Introduction: Quetiapine is available in both immediate-release (IR) and extended-release (XR) formulations. Quetiapine XR overdose is known to cause delayed increase in serum quetiapine concentrations. However, it is not certain whether quetiapine IR overdose would similarly cause a delayed increase in serum quetiapine concentrations.

Introduction: Intentional multiple drugs overdose is an often-encountered method of self-harm in adolescence. Treatments include supportive therapy, antidotes (when available) and decontamination techniques with the aim of reducing drugs absorption by the gastrointestinal system to minimize toxicity. Nevertheless, the decontamination techniques currently used, such as gastric lavage (GL), activated charcoal or whole-bowel irrigation, have a questionable effectiveness.

Effect of lipid emulsion on neuropsychiatric drug-induced toxicity: A narrative review.

Medicine (Baltimore)

March 2024

Department of Anesthesiology and Pain Medicine, Gyeongsang National University College of Medicine, Gyeongsang National University Hospital, Jinju-si, Republic of Korea.

Article Synopsis
  • Lipid emulsion has been found to be effective in treating serious cardiovascular issues caused by toxic levels of certain neuropsychiatric drugs, particularly those that are lipophilic (fat-soluble).
  • A study analyzed case reports to evaluate how lipid emulsions impacted patient recovery based on the Glasgow Coma Scale and corrected QT intervals, focusing on specific drugs like amitriptyline and trazodone.
  • Results showed that 98.3% of patients improved with lipid emulsion treatment, although more research is necessary to fully understand its effects and optimize its use.
