Hello Sherif,
Ledifos is a generic Harvoni made by Hetero who are one of the better generic manufacturers.
Like Harvoni it is only suitable for genotypes 1, 4, 5 and 6. It does not work well on genotypes 2 and 3.
So, while it is an effective medication, and with F2-F3 a 12 week treatment course will have about a 95% cure rate you do need to know your genotype. Do you know it?
Online pharmacies vary from outright scams, through to people supplying fake products, through to totally honest merchants. It would be a good idea to check your viral load 4 weeks into treatment – there is an 80% chance this will be undetected at this stage.
Best of luck with the treatment and keep us posted here about how things go!
