I was told I could crush his oxycodone for his PEG by pain management team at the cancer center. I am always sure to ask before I put anything new through his PEG. Thank you for the warning, though. The chemo doctor just prescribed Fentanyl and Dilaudid. Our pharmacy was able to fill the Fentanyl patch but they didn't have the Dilaudid. That I haven't filled yet and would like to read up on what family of meds it's from before I fill it. The doctor explained that the Dilaudid was to be used for break through pain. I have to admit, I do get a bit nervous with these meds. Do you have to be weaned off of the Fentanyl patch?
