- major depressive disorder (depression)
- generalized Anxiety Disorder (excessive worry)

DULOXETINE SANDOZ is available only with a doctor's prescription.

For example, another medicine for depression called fluvoxamine. Check with your doctor or pharmacist if you are unsure as to whether or not you are taking a potent CYP1A2 inhibitor.
