My Internist handles my pain management because she sees me at least 4 times a year. My GI at the Mayo Clinic knows I take Norco and we've discussed that it is helping me in 2 ways, with pain and firmer stools. My surgeon knows I take it too. He asked me who was handling my pain management. He's the type that does the surgery and hands his patients back to their GI.
I've taken loperamide, generic Imodium, and think the prescription is better than the over the counter because it is powder in a gel cap versus a solid little Imodium pill. It seems to work closer to the time I take it than Imodium did. The main time for me was right before bed.
It isn't working for you and to suggest you have a major operation when a small dose of a narcotic works sounds like crazy logic to me. It's hard to change doctors, especially when you've had one a long time but in this case I'd see another GI and work it out with her/him if you need to go to someone else, like your PCP, for the prescriptions. The new laws require more from prescribing doctors and some have just quit prescribing narcotics to anyone. I think the prescribing doctor needs to see the patient every 3 months or so. The only change that happened with me is I have to physically pick up a prescription with an original prescribers signature monthly.
I believe Jan Dollar takes one prescription narcotic pill daily and she's had her j-pouch for decades.
P.S. Tylenol #3, Vicodin and Norco all contain the same ingredients but vary on how strong the hydrocodone and tylenol's content is.
