Hi , we recommend seeing a doctor or specialist, such as a hepatologist, who can support you with treatment. What you mention here are different drug formulations for hepatitis C medication, though you can't necessarily infer from that alone side effect differences. Everyone has different experiences and side effects with hepatitis C treatment. Do you have liver damage, and if so do you know the damage stage? Observationally, I've seen more patients with cirrhosis or extensive liver damage share experiencing side effects with treatment. Let us know what other questions you have. -Matt (Community Manager)
