Shellshocked, welcome back. I'm sorry things have taken such a bad turn with your hubby. It really sounds like HE to me. How much Lactulose is he taking in each dose? You might try increasing it. Are you sure that he is taking his meds regularly? BTW, it's Xifaxan. We have a thread for Medical Words for correct spellings on lots of liver related words.
You seem to really need some emotional support from other caregivers, so I suggest you check out the Caregivers Sharing thread. You can feel free to vent there.
Has any mention been made of evaluating him for transplant? What about treatment for Hep C? What were his discharge orders and prognosis?
Hugs,
Connie
