promethazine (phenargan) for anxiety? Saw my psych today who's prescribed 25mg promethazine for anxiety, after talking to a pharmacist to find a suitable medication that comes in liquid (he wanted to prescribe buspirone or lyrica but couldnt as I cant swallow tablets). It just seems a bit unorthodox, not heard of anyone taking promethazine for anxiety before.
