I was diagnosed with adhd 7 years ago, and just a few weeks ago with bipolar. i have been on any stimulant you can think of for adhd, and only some improvements with adderall. I have been taking Lamictal (a mood stabilizer) now for 3 weeks ago for the bipolar, and do not have any interactions between my adderall (xr and ir) and lamictal. For me, adderall has never sent me into a manic phase, but rather made me focus and be less hyper I guess you could say. The hypomanic phase I experienced and the hyperactivity that I have always had with the adhd are two completely different levels of activity. I was diagnosed when my pdoc upped my wellbutrin dosage from 150 mg sr to 300 mg xl. The medication sent me into my hypomanic phase and also brought along some unpleasant ringing in my ears. He said this reaction also explains why ssri's have not worked in the past for me. He asked me not to take my adderall for one week to see if that is what caused the episode, but it was not. I believe that some people have had stimulant induced manic episodes from stimulants, however, so it may be determined by your brain chemistry! I hope all goes well
