Elimination of Viibryd (vilazodone) is primarily by hepatic metabolism with a terminal half-life of approximately 25 hours.
It takes approximately 5.5 x terminal half life for the medicine to be out of your system. So, in a healthy adult Viibryd should be cleared in (5.5 x 25 hours = 137.5 hours or slightly more).
While our guru Marvel gave you a technical and correct reply, I will respond from my own experience. I metabolize Viibryd very rapidly. While the half-life is said to be around 24 hours, it only lasts about 18 for me. My Dr, for a time, had me taking 20 in the PM along with my 40 in the AM. Otherwise I would wake up feeling itchy, headachy etc. This has now resolved and my system has accepted a 40 mg daily dose, taken in the AM. Is there anything else we can clarify for you? Was your question more related to how long it would remain in the system to show up on a blood/urine test? You didn't give us enough information to help further.
I was admitted to the hospital yesterday with septic pneumonia. It's Saturday 6pm I took my last 40 mg dose of Viibryd at 7am on Thursday. I began nearly uncontrollably weeping at 2 pm today. The hospital just told me they don't have Viibryd and that I will be fine until I am discharged on Tuesday. If I am weeping after 60 hrs, what will I be like at 135 hrs? How can a hospital not have or not get a drug that a patient needs?
