Which medication is commonly used to treat Hepatitis C?

The commonly used medication for treating Hepatitis C includes both Ribavirin and Peginterferon. These antiviral medications have shown efficacy in reducing the viral load and achieving sustained virologic response in patients with Hepatitis C.

Ribavirin works by inhibiting the replication of the virus, while Peginterferon enhances the immune response to fight off the virus. In modern treatment regimens, direct-acting antiviral agents (DAAs) are also frequently utilized, which may include newer options such as sofosbuvir or ledipasvir, but Ribavirin and Peginterferon remain foundational in many treatment protocols.

Tenofovir and Entacavir, on the other hand, are primarily used for the treatment of Hepatitis B, not Hepatitis C. Their mechanisms of action and viral target specificity make them ineffective choices for treating Hepatitis C, which is a distinct viral infection requiring specific antiviral therapy.

Therefore, Ribavirin and Peginterferon are the correct answers for commonly used medications in the treatment of Hepatitis C.
