"i cannot find any medicines to work for me. was on viibryd 10mg for two weeks and then went to 20mg for a week and a half. i broke out in a rash for 3 days then it went into hives. ended up in an urgent care, recieved cortisone shot and prednisone. doctors think it is from viibryd because i have not tried anything new or done anything differently. now i&#039;m on my second prednisone pack because they have come back.
