Depression, or major depressive disorder, is a mood disorder which is more than a feeling of sadness. It is a condition which impacts day-to-day activities, with several different symptoms which may include a feeling of sadness, loss of interest in regular activities, weight change, a change in sleep patterns, and thoughts of suicide.  Viibryd® is prescribed to treat the symptoms of MDD, and is thought to work by changing the levels of serotonin in the brain.
Viibryd® must be taken with food, and is taken at about the same time every day.  Generally, treatment will start with a low dose to prevent or reduce gastrointestinal problems, and the dose will be increased over time. While Viibryd® may cause the symptoms of depression to improve, it is not a cure, and discontinuing Viibryd® without doctor's instructions may permit symptoms to return.  
Viibryd® is not a controlled substance and is not commonly abused. Animal studies have not suggested that Viibryd® abuse or dependence is likely. Five patients, including one child, have overdosed on Viibryd® and all have recovered. Symptoms of overdose have included serotonin syndrome, lethargy, restlessness,hallucinations, and disorientation.
