I have an anxiety disorder in which i take citalopram and budeprion daily. I also take diazepam when i have panic attacks. I used to have panic attacks several times a month but since i have been taking this medicine it has cut down a lot. Now they rarely come… except for that last few weeks. I have experienced a rise in panic attacks lately and am concerned. So please answer this question if you know the answer…. can excessive panic attacks be a sign of something worse. Or am i just giving myself more anxiety by thinking like this?
