Vilazodone — Uses, Dosage, Side Effects & Safety

Drug class: Antidepressant (Selective Serotonin Reuptake Inhibitor and 5-HT1A Receptor Partial Agonist)

Overview

Vilazodone is a prescription medication used to treat major depressive disorder (MDD) in adults. It helps improve mood, sleep, appetite, and energy levels, and may help restore interest in daily living. Vilazodone works by increasing the levels of serotonin, a natural substance in the brain that helps maintain mental balance. It acts as both a selective serotonin reuptake inhibitor (SSRI) and a partial agonist at the 5-HT1A receptor, which may provide additional antidepressant effects. Key points for patients: Take vilazodone exactly as prescribed, usually once daily with food. It may take several weeks to feel the full benefit. Do not stop taking vilazodone suddenly without consulting your doctor, as this can cause withdrawal symptoms.
