He moved home to get off of them and was down to 20 mg IV daily. He slowly, over 3 weeks, tapered from 180 mg IV daily. Now he has kidney stones. Of course the pain meds are immediate release opiates and don't work as well as they could because of his tolerance. We need to control his pain without feeding his addiction any more than we absolutely have too. Any suggestions that I can discuss with his doctor would be appreciated.
