There doesn't seem to be a way to program in the prn doses. This CADD is used generally for chemo--the onco's office loaned it. The wife is giving the prn doses. I thought they said he uses the prn a lot, turns out it is still a little rare.
The wife is very young also, but has learned a lot and the onco has confidence in her. I didn't see any of the usual flags for concern about "loose" morphine in the house (makes me wonder why there's little concern for Roxanol at twice the strength, but worry about other forms
), and I did also ask.
As for increasing the dosage, he resists that. He does not want to be out of control, doesn't want to feel at all fuzzy. Would rather tolerate the discomfort.
At 27, he seems to be fighting dying while being OK with his impending death. I did talk with him about kicking the crap out of the pain before it gets a good grip, maybe that will help him.
