I am newly diagnosed with having a panic disorder along with depression. I went to see the doctor yesterday and he prescribed me medications. One to handle my depression named Effexor. One to handle my problem with sleep named Trazodone and Xanax to handle my sever panic attacks. I have not started these meds yet because a little over 48 hours ago I was given a very small piece of a pill called suboxone by a friend(i know it was wrong to take but it did help),My question is this, if I start my meds today..do you think I would have harmful interactions...
