If you are comparing the Liver damage of DHC with Hydrocodone, I may be wrong, as I am no physician, but usually the liver dammage associated with Hydrocodone is from the APAP that is in them (Acetaminophen=APAP)
example: 10/500 = 10mg Hydrocodone & 500mg APAP. Or 10/325 = 10mg Hydrocodone & 325 APAP. I am aware that most of you guys know this, but I am sure that a few of you don't. I hope I have helped at least one person, that would make it worth the time I have spent. Thanks for a great informative forum. You guys have saved me hours of research at times. Just trying to give a little back
