What drug schedule is amtitriptyline on? I was arrested when I was pulled over and had an amtitriptyline pill on the floorboard of my car. I was charged with possession of a controlled substance and not having a controlled substance in the proper container. I have a RX for same but I must have dropped this one pill sometime. Anyway, at the show cause hearing the police officer testified that it was a Schedule I or II drug. Is this true? I cannot find it on any of the schedules! Thanks for your help!
