My dr. prescribed Klonopin for me to take for my anxiety while taking Wellbutrin for depression. I REALLY didn't want to take the Klonopin, after reading about how addictive it is and that NIH recommends that you not be on it for more than 4 months. So I haven't taken it. So far I am OK on the Wellbutrin - not as good as on Effexor but no major episodes as of yet.
This doesn't really answer your question, but it is my experience. I would be interested to hear if you have taken the combo and how it works.
buspar and klonapin are both tranquillisers but are different types, i suggest you take 1 or the other but not both
buspar isnt effective against panic attacks, K is
