I know that for PCT stuff people take things to help with the health of their liver and such so I was hoping to get some ideas on stuff my dad could use. His back is messed up bad and he's waiting to get surgery on it, but they have to run all these heart tests to first to make sure his heart is stable enough to actually go under for the surgery. The back has been a problem for years now, and before that it was his shoulder (surgery) and before that it was his knee (2 surgeries). Essentially, he has been badly injured in one way or another for 10 years now and he takes pain meds constantly. He more-or-less lives on Darvocet and other stuff to keep the back pain manageable until he finds out about surgery. I am worried about the health of his liver with all this pain medication he has been on for years and years. Fortunately, he almost never drinks alcohol so that helps, but I was hoping I could get some ideas on what to use for liver health. For the record, any suggestions made WILL be cleared with both a doctor and pharmacist to make sure there are no drug interactions since between his pain meds, heart meds, and blood pressure meds he takes like 15 pills a day. Thanks.
