Before starting EPCLUSA 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. 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 EPCLUSA.
Tell your healthcare provider about all of your medical conditions, including if you have ever had hepatitis B infection or liver problems other than hepatitis C infection; if you have severe kidney problems or are on dialysis; if you have HIV; or if you are pregnant or breastfeeding, or plan to become pregnant or breastfeed. It is not known if EPCLUSA will harm your unborn baby or pass into your breast milk. If you take EPCLUSA 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. EPCLUSA and certain other medicines may affect each other or may cause side effects.
