Hello, harvoni practically has no side effects, the efficiency is 90%.
I had hep c for 37 years after 30 years of being infected I was diagnosed with cirrhosis. I treated 3 times in the past with interferon based treatment and had no decrease in viral count. So being a person that had prior treatment and been a null responder plus having liver cirrhosis for 7 years by the time I treated with Harvoni all were reasons I would be harder to cure.
I am now 2 years post treatment and cured of hep c.
In general odds of cure are around 98% or better with most people reporting minimal side effects the most common being mild headache which can be reduced by staying properly hydrated.
For me treatment was a walk in the park like taking a multivitamin.
If Harvoni can cure someone like me it can cure you too.
Good luck on treatment
Side effects are minimal according to most people especially those who once treated with interferon. The success rates are well over 90%.
