A 32-year-old male patient who recently began taking a medication for depression reports that he has had painful erections. The most recent one lasted more than 1 hour. The PMHNP should instruct him to discontinue:

Choice A reason: Alprazolam, a benzodiazepine, is associated with sedation and anxiety reduction but is not commonly linked to priapism. Choice B reason: Desvenlafaxine, an SNRI, may cause sexual side effects but rarely induces priapism. Choice C reason: Trazodone is a known cause of priapism due to alpha-adrenergic blockade, and prolonged painful erections require immediate discontinuation and medical attention. Choice D reason: Lamotrigine rarely causes priapism and is primarily used as a mood stabilizer; it is unlikely to be the culprit in this scenario.
