I am a post roux-en-y Bariatric patient. I've lost almost 90 pounds since and I'm now a normal weight. Four years ago, I got meningitis and now have a pain disorder and severe migraines that require dilaudid injections (6mg IM with 50mg promethazine IM) that my PMS prescribes for me. She also has me on methadone (30 mg daily) for chronic pain, but is changing me to a med called Exalgo 16mg daily. Can Bariatric patients take ER medications?
