Victrelis Boceprevir Dosage Modifications

Victrelis™ (boceprevir) and Hepatitis C

What if one has an adverse reaction to the Victrelis™ combination therapy?

Reducing the dosage of Victrelis™ is not recommended by Merck. However, if one experiences an adverse reaction that is possibly related to the peginterferon alfa and/or ribavirin, the peginterferon alfa and/or ribavirin dosage could be reduced or discontinued based on the information provided in these medications’ Package Inserts regarding how to reduce and/or discontinue peginterferon alfa and/or ribavirin dose.

Victrelis™ cannot be administered if peginterferon alfa and ribavirin are discontinued.
