There're antiviral drugs avaialble.
Researchers have recently made significant advances in treatment for hepatitis C using new, "direct-acting" antiviral medications, sometimes in combination with existing ones. As a result, people experience better outcomes, fewer side effects and shorter treatment times — some as short as eight weeks. The choice of medications and length of treatment depend on the hepatitis C genotype, presence of existing liver damage, other medical conditions and prior treatments.
So always consult a specialist before taking medication.
