Prednisone
"My experience was awful!!!! I took this for an ear infection.  I have suffered with anxiety in the past.  Let me tell you after 2 days of taking this I was so anxious.  I stopped taking it and the next day I had to go to the Dr to get ativan for my anxiety.  It was awful like the worst anxiety ever. I am still having anxiety from this drug a week later.  It's an awful drug.  Don't take it!!!"
