Thank you, I don’t knw if my first question was received, so am sending it again. I have severe arthritis with two joint' s already completely replaced. I am attempting to hold the pain at bay, working with an anesthesiologist/pain doctor, using morphine 30 mg. 2 twice a day, and Tylenol 4 for breakthrough. I have always had a problem with constipation intermitantly, so the drugs are causing big problems. I am looking for a list of drugs especially for OIC, so that I can check out my insurance company to see if. They approve any drugs.
