Important Safety Information

What is the most important information I should know about HARVONI?

HARVONI can cause serious side effects, including:

  • Hepatitis B virus reactivation: Before starting HARVONI treatment, your healthcare provider will do blood tests to check for hepatitis B infection. If you have ever had hepatitis B, the hepatitis B virus could become active again during and after treatment with HARVONI. This may cause serious liver problems including liver failure and death. If you are at risk, your healthcare provider will monitor you during and after taking HARVONI.

What should I tell my healthcare provider before taking HARVONI?

  • If you have: ever had hepatitis B infection, liver problems other than hepatitis C infection, or have had a liver transplant; severe kidney problems or are on dialysis; HIV, or any other medical condition; or if you are pregnant or breastfeeding or plan to become pregnant or breastfeed. It is not known if HARVONI will harm your unborn baby or pass into your breast milk. If you take HARVONI with ribavirin, you should also read the ribavirin Medication Guide for important pregnancy-related information.
  • Tell your healthcare provider and pharmacist about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. HARVONI and certain other medicines may affect each other, or may cause side effects. Tell your healthcare provider if you take any medicines containing tenofovir disoproxil fumarate (ATRIPLA®, COMPLERA®, STRIBILD®, TRUVADA®, VIREAD®).
