a 70 year old female with depression for the past 3 months presents to urgent care with complaints of dizziness and lightheadedness. She also has diabetes, atrial fibrillation, Parkinson’s disease, congenital prolonged QTc, and bilateral knee replacements. The patient has had the same medication regimen “for years,” including levodopa, metformin, and clopidogrel. She was also started on an antidepressant recently but cannot remember the name. Physical exam reveals no concerning signs. However, her lab work reveals a serum sodium of 127. Which medication is the patient most likely using to treat her depression?
