Which antidepressant is noted as having potential serotonin syndrome risk when used with sumatriptan?

• A. Citalopram
• B. Sertraline
• C. Mirtazapine
• D. Lofepramine

Answer: (D)

Serotonergic interactions with sumatriptan can lead to serotonin syndrome because sumatriptan increases serotonin activity in the brain, and adding a drug that raises serotonin levels further can push it into a dangerous range. Lofepramine, a tricyclic antidepressant with notable serotonergic reuptake inhibition, is particularly implicated in this interaction. When used together with sumatriptan, the risk of serotonin syndrome is increased, so this combination is one clinicians are cautioned about and may avoid or monitor closely. In this context, lofepramine is the option most associated with a notable interplay with sumatriptan, which is why it’s identified as the best answer. The other antidepressants listed are also serotonergic and can contribute to risk, but the question emphasizes the combination that is specifically highlighted for this interaction in many guidelines, namely the serotonergic effects seen with lofepramine. If such a combination is necessary, clinicians typically consider alternative treatments or monitor for early signs like agitation, confusion, rapid heartbeat, high blood pressure, dilated pupils, muscle rigidity, and fever.
