Vortioxetine, a newer antidepressant, was prescribed to an elderly male in his 80s with major depressive disorder, in combination with mirtazapine. Despite initial improvement in mood, he developed hyponatraemia, a rare but serious side effect possibly linked to vortioxetine\u2019s serotonergic action. The patient exhibited symptoms such as giddiness and confusion, prompting the discontinuation of vortioxetine and initiation of corrective treatment. His condition improved, with sodium levels returning to normal while he was maintained on mirtazapine alone. This case underscores vortioxetine\u2019s potential to induce SIADH, highlighting the need for careful monitoring and the consideration of alternative antidepressants in vulnerable populations.<\/jats:p>","DOI":"10.1136\/bcr-2024-262735","type":"journal-article","created":{"date-parts":[[2025,2,26]],"date-time":"2025-02-26T09:20:25Z","timestamp":1740561625000},"page":"e262735","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Vortioxetine-associated
