Although there was partial improvement in the patient’s mood and anxiety symptoms with antidepressant treatment, insomnia remained a persistent complaint despite adequate trials of different sleep medications. The novel hypnotic, suvorexant (Belsomra, Merck & Co.) was then initiated at the recommended bedtime dose of 10 mg and was followed by a 15 mg dose the following night. Within an hour after taking her second suvorexant dose, the severity of patient’s depression symptoms worsened and was accompanied by new onset of suicidal thoughts.
