Hi, I have always taken Xanax on "as needed" basis, not every day. When my psychiatrist prescribed the Buspirone, she said if I had a panic attack (which of course is different from anxiety), I could take a Xanax even though I may have taken the Buspirone. I was actually wary of doing that, but I did take .5 mg Xanax one day because of severe panic attack, and I did not have any issues. I plan not to take Xanax while taking Buspirone unless absolutely necessary. I haven't been taking the Buspirone long enough to comment on whether it is working for me or not. I just know I noticed 2 symptoms almost immediately that I did not have before taking the Buspirone (1) Whooshing kind of sounds in my ears-pretty loud (2) Mild nausea. I did not know if this was common or what others had experienced. Thanks to everyone for your feedback. I appreciate each of you for taking the time to respond.
