What is vilazodone?

Vilazodone is an antidepressant that is used to treat major depressive disorder (MDD).

Vilazodone may also be used for purposes not listed in this medication guide.

Important Information

Do not use vilazodone if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

Some young people have thoughts about suicide when first taking an antidepressant. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.

Vilazodone is not approved for use by anyone younger than 18 years old.

Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting.
