Fortunately, the list of medications and supplements that may interact with those used to treat hepatitis C virus (HCV) infection is relatively short. However, before starting a new medication, it’s a good idea to review everything you are taking. If your review includes supplements, over-the-counter medicines, recreational drugs and food, you’ll get a more complete assessment.
Before starting treatment, read the information that accompanies the drug prescribed for your treatment. HCVGuidelines.org provides a list of common drugs known to interact with HCV antivirals. The University of Liverpool HEP Drug Interaction checker is available at hep-druginteractions.org. If you are looking for information about everything you are taking, many good interaction checkers are available online. The Canadian site DrugBank is especially impressive.
