Lipitor and Pegasys drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Lipitor (atorvastatin calcium) and Pegasys (peginterferon alfa 2a). Common drug interactions include blood bilirubin increased among females and fatigue among males.
The phase IV clinical study analyzes what interactions people have when they take Lipitor and Pegasys. It is created by eHealthMe based on reports of 129 people who take the same drugs from the FDA, and is updated regularly.
