Yes of couse when they received medicine (Peg-interferon and ribavirin) and non respodered.
I treated three times with interferon based treatment and was a null responder. My viral load actually increased on treatment.
But even though I was a three time null responder with cirrhosis I was able to be cured with Harvoni.
There are also several other new medicines available that are very effective. Depending on your genotype one of the other new meds may be an even better choice than Harvoni.
See your doctor to find out what is the best treatment for you.
You can be cured with the new meds now available.
