It should be used with caution in patients with substantial alcohol use. Mydriasis has been reported in association with duloxetine; therefore caution should be used when prescribing Zenbar in patients with raised intraocular pressure or those at risk of acute narrow-angle glaucoma. Increased plasma concentrations of Zenbar occur in patients with sever renal or hepatic impairment. A lower starting dose should be used in such patients. The possibility of a suicide attempt is inherent in depression and may persist until significant remission occurs. Close supervision of high-risk patients should accompany initial drug therapy.

Studies from some antidepressants indicate a potential increased risk for suicidal ideation and behaviors in pediatric conditions compared to placebo.
