Does anyone know if Harvoni continues to work in your system when not taking the medication? I was initially approved for 8 weeks and VL dropped from 6.4 to 1.2 now it is un-reportable but still detectable. My insurance company will not approve me for another 12 weeks. Liver enzymes normal. Insurance company is calling me a "non-responder" because I still have the virus even though it is almost gone. Any feedback would be great. Really upset about this issue.
