FDA Drug Safety Communication: Updated information on drug interactions between Victrelis (boceprevir) and certain boosted HIV protease inhibitor drugs

The U.S. Food and Drug Administration (FDA) is notifying the public that co-administration of Victrelis (boceprevir), a hepatitis C virus (HCV) protease inhibitor, along with certain ritonavir-boosted human immunodeficiency virus (HIV) protease inhibitors, is not recommended at this time because of the possibility of reducing the effectiveness of the medicines, permitting the amount of HCV or HIV virus in the blood (viral load) to increase.
