Precautions

It is important that your doctor check your progress at regular visits to allow for changes in your dose and to help prevent any unwanted effects. Blood tests may be needed to check for unwanted effects.

Do not start taking vilazodone during the 2 weeks after you stop a MAO inhibitor and wait 2 weeks after stopping vilazodone before you start taking a MAO inhibitor. If you take them together or do not wait 2 weeks, you may develop confusion, agitation, restlessness, stomach or intestinal symptoms, a sudden high body temperature, an extremely high blood pressure, or severe seizures.

Vilazodone may cause some teenagers and young adults to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. Some people may have trouble sleeping, get upset easily, have a big increase in energy, or start to act reckless. If you or your caregiver notice any of these unwanted effects, tell your doctor right away. Let the doctor know if you or anyone in your family has bipolar disorder (manic-depressive) or has tried to commit suicide.
