Hi! I believe I can be of help with this issue.
Your doctor is most likely suggesting this method as both medications are the same class of antidepressant. They are both SSRIs.
I don't know if your doctor is also taking into consideration previous knowledge of how you tolerate medications. If that's the case, then I can't comment.
Generally, though, the more common way to switch medications is to titrate down from one and then titrate up to the new medication. So in your case it would be tapering off the Celexa and at one point introducing the Viibryd. Many doctors overlap them for a few days at the lower dosages.
So bring this strategy up with your doctor as a possible alternative and discuss it and go from there.
Okay, I wish you the very best!
