I've just registered to this forum even though I have often peeked in for information. I've just switched from dilaudid to demerol for stricture pain/obstructions. I was getting terrible itching from the dilaudid - and not the best pain relief. Demerol dosage is 50mg/day as necessary. Is that a joke? So far,150 mg will help but I need to take it every 3 hours - this is wayyyy beyond the suggested posology...and I am having some itching. Should I ask for something else?
