Effectiveness of PEGASYS® (Peginterferon alfa-2a)

With PEGASYS and COPEGUS® (Ribavirin, USP) combination therapy, the hepatitis C virus can be decreased to a level so low that it cannot be measured by blood tests. After 3 to 6 months of therapy, a blood test can help your healthcare professional determine your likelihood of long-term response.

Depending on the type of hepatitis C you have (your genotype), the virus is decreased to a point where it cannot even be detected in 5 to 8 out of every 10 people who take PEGASYS and COPEGUS combination therapy for 6 months to 1 year.

Effectiveness of PEGASYS

Unlike other chronic illnesses that require taking medications for life, hepatitis C treatment is typically for either 24 or 48 weeks depending upon the genotype of the virus you have.
