Quetiapine, a pharmacological agent within the class of atypical antipsychotics, is characterized by its efficacy in mood stabilization and its role in the modulation of serotonergic and dopaminergic pathways. Its therapeutic utility is broad, encompassing the management of acute psychotic episodes, schizophrenia, bipolar disorder, and treatment-resistant depressive states. Quetiapine's effectiveness extends to depressive disorders that do not exhibit classic psychotic features, with a side effect profile that is less burdensome than many alternative psychotropic medications. Its versatility in addressing a range of psychiatric conditions is useful in the psychopharmacological management of mood and thought disorders. However, like all drugs, quetiapine may have different effects relative to the individual. It is imperative to approach the administration of quetiapine carefully, ensuring any adverse effects are ameliorated for beneficial therapeutic outcomes. In this case report, we present a psychosis-naive 42-year-old male who developed psychotic symptoms after beginning a quetiapine regimen in order to manage major depressive disorder with suicidal ideation. Clinical suspicion of quetiapine-induced psychosis was a diagnosis considered due to symptom remission secondary to ziprasidone in the place of quetiapine. The determination of a suspected adverse drug reaction can utilize the Naranjo scale to demonstrate the likelihood of an adverse drug reaction. This patient scored a three on the Naranjo scale, indicating a possible adverse effect from quetiapine. Other potential etiologies of psychosis include medication-induced psychosis, major depressive disorder exacerbation, cocaine use/withdrawal, and brief psychotic disorder. Quetiapine-induced psychosis has not been described in the current literature, and therefore, this case report is solely based on clinical evaluation and is intended for educational purposes due to possible confounding factors and etiologies., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Valentine et al.)

In patients with hyperlipidemia and cardiovascular disease, statin remains the primary medication for risk reduction. Statins are primarily associated with adverse outcomes like myoglobinuria and deranged liver function tests (LFTs). Angioedema is a life-threatening reaction characterized by mucosal and submucosal swelling. It is rarely known for its association with statins. However, we present a rare case of a 59-year-old man presenting with recurrent angioedema of the face and tongue after starting on 40mg of atorvastatin, within one week of the treatment. He had no previous history of hypersensitivity and rash. He denied any food or medication allergy in the past. The Naranjo scale probability and the abrupt nature of these episodes upon starting statin and completely resolving after discontinuing the drug made statin-induced angioedema the primary diagnosis in this case., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Voloshyna et al.)

Drug-induced fever is a significant adverse effect as many commonly used medications can cause this. The incidence of drug fever is even higher in critical care settings because multiple medications are being administered simultaneously. This poses a serious problem in critical care settings as any new fever in these settings also implies any new infection or worsening of preexisting conditions. This may lead to a detailed investigation for the cause of fever, which can be time-consuming, invasive, costly, and may also increase the duration of stay along with an associated increase in morbidity and mortality. We want to highlight an adverse drug event through a documented case of Dexmedetomidine- induced fever in a critical care patient with multiple pathologies., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Imtiaz et al.)

The anesthetic management of patients with chronic pain requires a thorough understanding of the physiologic changes resulting from long-term exposure to opioids, as well as a firm comprehension of the pharmacodynamic and pharmacokinetic properties of these medications. We present the case of a 60-year-old woman on methadone therapy presenting for cervical laminectomy and fusion. After intraoperative dysrhythmias, she underwent pharmacological cardioversion from torsade de pointes. This occurred intraoperatively after receiving 25 mg of intravenous diphenhydramine to attenuate erythema thought to be secondary to antibiotic administration. The use of a routine antihistamine may present a torsadogenic reaction in the setting of methadone maintenance treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Hoffman et al.)
