A few weeks ago, my doc prescribed me a different brand of levo I believe, and the color of the pills were pink (112mg), and since taking them I have constant panic attacks and random episodes of anxiety. I have had anxiety before with certain dosages but never this dose; I have also never taken this color pill. I emailed my doctor and he said I could be allergic to the color coating and that may be whats triggering these racing thoughts and panic attacks. However, I can't get the dosages changed for a few more weeks.. What can I do? And is this normal side-effect?
