🧠Psych Lecture 1- Mood Disorders Flashcards (part 2)

An 62-year-old female with a recent history of hypertensive emergency is being started on an antidepressant. Which of the following medications should be avoided?
• A) Sertraline • B) Mirtazapine • C) Fluoxetine • D) Desvenlafaxine • E) Fluvoxamine

D;Because SNRIs (venlafaxine, desvenlafaxine, etc.) can raise blood pressure, they should be avoided in patients with a history of hypertensive crisis/emergency.
