Postmarketing studies have reported that duloxetine and some other SNRIs like milnacipran may aggravate preexisting liver disease. The use of duloxetine delayed-release and milnacipran should be avoided in patients with chronic liver disease or cirrhosis.

Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.

SNRI antidepressants cause pupillary dilation that may trigger an angle closure attack in patients with anatomically narrow angle without iridectomy.
