ondansetron + sertraline

Ondansetron + sertraline is a combination of two pharmaceutical drugs, each with distinct mechanisms of action. Ondansetron is a selective serotonin 5-HT3 receptor antagonist primarily used to prevent nausea and vomiting associated with chemotherapy, radiation therapy, and surgery. Sertraline is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed for depression, anxiety disorders, and related conditions. When used together, these agents can increase serotonergic activity in the central nervous system. This combination raises the risk of serotonin syndrome—a potentially serious condition characterized by symptoms such as agitation, confusion, rapid heart rate, dilated pupils, muscle rigidity or tremor—due to additive effects on serotonin levels[2][4][5]. The use of this combination should be carefully monitored by healthcare professionals.
