Last Monday I had my annual endoscopy of the colon performed at one of the major hospitals in Grand Rapids Michigan. Prior to the procedure the nurse was going over her check list, advised me the physician who was performing the endoscopy used Demerol along with the sedative. I advised her that I had recently been advised by the Parkinson network that if one was taking Eldrypl. the administration of Demerol could be fatal. She acknowledged she was unaware of this and called the hospital pharmacist. After some discussion between the two of them she reported the pharmacist did indeed say there was some incidences reported where this has occurred. After conferring with the physician she reported back to me that he choose to use Talwin instead of Demerol. Having pre reported my taking Eldrypl in my chart I can only assume he knew of this possible interaction between the two drugs. Since I believe we should be personally responsible for own health, whenever possible, it is a good idea to keep in mind what we learn from this net as well as other sources. Jim Ryan 56/7
