Tell the doctor right away if the patient has symptoms like worsened depression, suicidal thoughts, or changes in behavior. Discuss any questions with the patient's doctor.


Viibryd is used for:

  • you are taking or have taken linezolid, a monoamine oxidase inhibitor (MAOI) (eg, phenelzine), or St. John's wort within the last 14 days
