Incivek™ (telaprevir) and Hepatitis C

When is Incivek™ contraindicated?

The same contraindications that pertain to peginterferon alfa and ribavirin also apply to Incivek™ combination treatment. The combination treatment is contraindicated in the following:

  • Pregnant women and men whose female partner is pregnant due to the risks for birth defects and fetal death associated with ribavirin.
  • Coadministration with drugs that are highly dependent on CYP3a for clearance, and for which elevated plasma concentrations are associated with serious and/or life-threatening events. It is also contraindicated with drugs that strongly induce CYP3a and thus may lead to lower exposure and loss of efficacy of Incivek™. The following drugs are contraindicated:
