Hi Lily and welcome,
There are quite a few people who have treated successfully or are currently treating with Twinvir here, no doubt some of them will be able to tell you more of their story but if you put that name in the search function you will find plenty of reading regarding it. It has been available for almost a year now but I understand the maker has only recently entered the African market.
Twinvir is a generic version of Harvoni (Sofosbuvir 400mg + Ledipasvir 100mg) that is manufactured by Incepta Pharmaceuticals who are listed in our manufacturers section fixhepc.com/forum/daa-access/435-incepta...ac-sof-led-comb.html
along with contact information. It is an effective one pill per day treatment for HCV genotype 1 when taken for the appropriate length of time.
Ribavirin is an 'add on' drug that won't cure HCV on its own, it used to be used in combination with Peg Interferon but these days is usually used to increase the effects of modern DAA (direct acting antiviral) medications such as Twinvir in difficult to treat cases such as those with cirrhosis or who have failed previous treatments.
Hepantivir is a 'herbal medicine' that is claimed to cure all types of hepatitis, it doesn't and there is no scientific or medical proof to show that it works. www.hepb.org/blog/buyer-beware-when-some...-a-counterfeit-drug/
My recommendation would be to spend your money on tested and proven medications like Twinvir or the equivalent product from any one of a number of Indian or Bangladeshi manufacturers many of which you will find listed in our generic medications access section. fixhepc.com/forum/generic-medication-access-channels.html
I hope that assists you and if you or your relative have any questions please ask.
