If you have hep c in late stage is that called cirrosis? Can you take the medication :lansoprazole" if you have cirrosis of the liver?

Complicated. Lansoprazole is broken down by the liver and if the liver has cirrhosis and a lot of damage full doses may not be appropriate. Cirrhosis is advanced scarring and you can have a liver that still works pretty well or one that is failing (decompensation). It is important to be evaluated to see if there is cirrhosis. If so, all medications, incl over the counter, have to be discussed with your doctor.
