have been taking enough pain pills from the beginning that my PEG diarhea has been perfectly balanced with the narcotic constipation. !!!
In my experience, vicodin does NOT do well in a PEG tube even if crushed up as it clots and clogs the tube. All my other pain pills and nausea drugs (percocet, oxycodone, Zofran, Compazine) crush well and work okay in the tube and I did clear each of them with my doctors (one even put it on the script bottle instructions: crush and insert w/water in PEG)
None of my chain pharmacies were able to come up with liquid versions without "special ordering" and a week delay. the Hospital pharamacy did have liquid percocet - Roxicet, which has worked well. The chain pharms don't like to carry "narcotics" around here due to junkie breakins and DEA paperwork hassle.
