Olanzapine has high affinity for serotonin, dopamine, alpha1-adrenergic, histamine H1, and muscarinic receptors and exhibits antidopaminergic, antiserotonergic, and antimuscarinic effects.<a class="elsevierStyleCrossRef" href="#bb0005"><span class="elsevierStyleSup">1</span></a> The main symptoms of olanzapine intoxication are decreased consciousness, hypotension, tachycardia, and excessive salivation, and usually symptomatic and supportive treatment is given.<a class="elsevierStyleCrossRef" href="#bb0010"><span class="elsevierStyleSup">2</span></a> However, to our knowledge, respiratory depression has not been reported with doses as low as 5 mg. This study reports the case of an elderly woman with severe hypercarbia, hypoxia, and impaired consciousness possibly due to low doses of oral olanzapine. We expect that this case report will add to the existing body of literature on the appropriate use of olanzapine.</p></span><span id="s0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="st0060">Clinical case</span><p id="p0010" class="elsevierStylePara elsevierViewall">A 78-year-old woman presented to the emergency department with impaired consciousness and hypoxia. She had a history of schizophrenia which had been treated with olanzapine 5 mg/day and valproic acid 200 mg/day for approximately 2 years in a psychiatrist's office. She had no medical or surgical history. She had no history of addiction, and her medications were properly administered by family members. Her Glasgow Coma Scale (GCS) score was E3V4M4, body temperature was 36.6 °C, blood pressure was 94/66 mmHg, respiratory rate was 14 breaths per minute, heart rate was 69 beats per minute, and oxygen saturation was 78% (room air). The surface electrocardiogram revealed a right bundle branch block. Transthoracic echocardiography showed normal cardiac function with an estimated ejection fraction of 60%. Chest X-ray revealed cardiomegaly with a cardio-thoracic ratio of 57.6% and pulmonary congestion. Head computed tomography was unremarkable. Arterial blood gas evaluation revealed severe hypoxemia, chronic respiratory acidosis, and metabolic alkalosis (pH 7.41; pO2 65.3 mmHg; PaCO2 82.7 mmHg; HCO3 46.8 mmol/L). Multiple nasal swab PCR tests for COVID-19 were negative. We diagnosed her for congestive heart failure and put on non-invasive positive-pressure ventilation (NPPV) with spontaneous/timed mode (FiO2 1.0; inspiratory positive airway pressure 10 cmH<span class="elsevierStyleInf">2</span>O; expiratory positive airway pressure 5 cmH<span class="elsevierStyleInf">2</span>O) in the emergency room. We suggested endotracheal intubation, but she and her family refused. We admitted her to the high care unit, treating her with intravenous bolus furosemide 40 mg/day, normal saline, and potassium chloride. All oral medications were discontinued. Serum renin was 0.2 (ng/mL/h, normal; 0.3–3.9) and aldosterone was 4.0 (pg/mL, normal; 40–82.1), ruling out primary aldosteronism. Because her breathing was shallow and slow (median tidal volume was 220 mL and respiratory rate was 14 breaths per minute), hypercarbia did not improve readily (<a class="elsevierStyleCrossRef" href="#t0005">Table 1</a>). Her level of consciousness gradually improved and her breathing became deeper and deeper. She was weaned from NPPV on day 19. She was discharged on day 30. Valproic acid was resumed after discharge from hospital, but the patient has progressed without recurrence.</p><elsevierMultimedia ident="t0005"></elsevierMultimedia></span><span id="s0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="st0065">Discussion</span><p id="p0015" class="elsevierStylePara elsevierViewall">Olanzapine has an average half-life of 33 h in healthy individuals, but longer in elderly patients, women, and non-smokers.<a class="elsevierStyleCrossRef" href="#bb0015"><span class="elsevierStyleSup">3</span></a> Although there have been a few reports of olanzapine causing respiratory depression, most have been at very high doses, and this paper classifies 120–840 mg as moderate poisoning.<a class="elsevierStyleCrossRef" href="#bb0020"><span class="elsevierStyleSup">4</span></a> As far as we know, the lowest dose of olanzapine to cause coma was 20 mg/day, but this case did not cause respiratory depression.<a class="elsevierStyleCrossRef" href="#bb0025"><span class="elsevierStyleSup">5</span></a> The patient was an elderly non-smoking woman, who may have decreased clearance and increased blood levels of olanzapine.</p><p id="p0020" class="elsevierStylePara elsevierViewall">In a multicenter, randomized, double-blind, placebo-controlled study of 356 patients taking olanzapine 5 mg for 4 days in Japan, no cases of serious side effects, including respiratory depression, were observed.<a class="elsevierStyleCrossRef" href="#bb0030"><span class="elsevierStyleSup">6</span></a> In this case report, olanzapine caused edema that took 2 weeks to improve after discontinuation.<a class="elsevierStyleCrossRef" href="#bb0035"><span class="elsevierStyleSup">7</span></a> Our case took about the same amount of time.
