Yes the oxys r both the same thing so don't get why he's on two kinds and doses and yes they can affect his kidneys and liver over time. But long use like alcohol.
Thank you so very much. No hepatitis- Had Multiple Myeloma cancer two years ago and his stem cell transplant produced an almost complete response but the pain management is for his lower back mostly. stenosis of the L5/S1
Does your father have Hepatitis C? I'm not entirely sure what you are asking but it sounds like the question is two fold. You can easily read the renal effect of these meds & how they are metabolized on line. I would talk to your father's doctor about the pain management strategy your father is following.
Pain management is complicated and knowing the reason why your father is taking the meds he is prescribed as well as the long-term goals and effects seems like something you have a right to ask about.

The Marinol, i would say is more for the nerve pain, which is probably why he is still on the oxy meds.
I hope that helps some. Good luck!
