Allergic?

I've been taking the suboxone for almost a month now. Almost the whole time I've had hives itching and/or swelling of the face. Well the doctor has just been prescribing me medicines to reduce those symptoms. Prednisone for the hives and sinequan (an anti-depressant) for the itching?? I'm wondering if this is even safe...I was under the impression that if you're allergic you cannot take the medicine in fear of worse reactions. Does anyone have any answers they wouldn't mind sharing? Thanks, Hazel
