buspirone + escitalopram
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Additive serotonergic effects increase risk of serotonin syndrome when buspirone is combined with an SSRI (escitalopram).
Mechanism of action
Pharmacodynamic: SSRI-mediated ↑ synaptic serotonin plus buspirone 5-HT1A partial agonism → heightened serotonergic activity.
Clinical management
Use lowest effective doses; monitor closely during initiation and dose changes for serotonin syndrome (agitation, diaphoresis, tremor, hyperreflexia, clonus, tachycardia). Educate patient. If suspected, discontinue serotonergic agents and provide supportive care.
