Used as an antidepressant for the treatment of major depressive disorder (MDD) in adults. It functions as a selective serotonin and norepinephrine reuptake inhibitor (SNRI), helping to restore the balance of certain natural substances in the brain. This improves mood, sleep, appetite, and energy levels, and reduces feelings of sadness and worthlessness. It is taken orally and may take several weeks to show full effect. Not intended for use in pediatric patients and requires careful monitoring for side effects such as increased blood pressure, suicidal thoughts, or serotonin syndrome.
