Take Xifaxin along with the Lactulose. So far no varices or ascites. Have had cirrhosis for 12 yrs, confusion is the biggest thing I have right now. How long does Lactulose take to work. Been on it 3tbsp 3x a day since Friday, it's now Sunday. No BM for days. I am so scared. I know I am at the beginning of the problems. My liver Dr tells what I want to know but I need more info. Please and thank you. I am so sorry for what everyone is going through.
