length of time on treatment will vary according to hepatitis C genotype,
previous treatment history and cirrhosis. People with no previous experience of
treatment will usually receive an 8 or 12-week course of treatment. People with
more advanced liver disease, or recurrence of hepatitis C after a liver
transplant may receive a 24-week course of treatment to give the best chance of
curing hepatitis C, depending on which drug combination is chosen.
