Fluoxetine
"I was prescribed this for use with my clonazepam in treating my panic disorder. I had three days of almost nonstop panic attacks before I went to my doctor. My doctor thought that there may be some depression as well and that the fluoxetine would work well with clonazepam if there was any depression with my anxiety. I took the medication for two months and noticed no advantages compared with clonazepam alone. "
