Hello!! I had a question about possible drug interactions with my prescription medications ... I currently take lexapro and xanax for anxiety/panic attacks ... And was just prescribed Allegra-D for my horrible allergies! I was wondering if this would have an adverse affect on my anxiety problems. I was prescribed Allegra-D in the past, but this was before my anxiety problems got worse. I am wondering if it possibly made them worse!? Please help! Thanks!
