I have been prescribed by my Radiology Oncologist a medication by the name of PMS-HYDROMORPHONE 1 MG TAB DIN & generic name , Hydromorphone Hydrochloride but have not taken it yet as I am allergic to demerol(go into shock) as well as sulfa drugs & have read the patient medical information sheets given by the pharmacist, and would like to know if there is any traces of demerol in this opiate, also under precautions it indicates this product may contain inactive ingredients such as sulfites, which I am also allergic to(red itchy rash). Please advise, thank you. Kathy
