If you live in Germany, you should be getting free treatment.
Can only tell you what it costs here in the USA. The total treatment costs around $50-60,000 USD. This is for someone needing to do 48 weeks of treatment. Some treatments are for only 24 weeks so that would be around $30,000. The cost is aprox for ALL the injections and the pills that are part of the treatment.
There are new drugs coming out next year that will be added to the current drugs, Peg-interferon & Ribavirin. The first one out should be Telaprevir. No one knows how much these new drugs will cost.
