Warnings and Precautions

Patients should seek immediate medical attention if any signs or symptoms of a hypersensitivity reaction occur during treatment.
- Serotonin syndrome has been reported with 5-HT3 receptor antagonists alone, but particularly with concomitant use of serotonergic agents such as medications to treat depression and migraines.
