Harvoni uses

It is primarily used for the treatment of chronic hepatitis C virus (HCV) infection in adults.

Here are some key uses listed below:

  • In patients who did not get any previous treatment

  • Treatment of Liver diseases
  • Offers simplified therapy

  • Patients who have never had hepatitis C therapy previously frequently obtain it as a prescription. It has demonstrated reasonable cure rates and is effective against all significant virus genotypes.

As an Alternative therapy

  • It also applies to patients who have previously received treatment for the illness without success. It provides a novel therapy alternative with increased efficacy and safety compared to earlier medicines.
