The FDA has warned that three Hepatitis C (HCV) drugs made by AbbVie, Gilead and MSD are worsening liver function and causing liver failure in some patients.
The US regulator said it has identified 63 cases in which HCV drugs Mavyret, Zepatier, and Vosevi were worsening liver function in patients with symptoms of moderate-to-severe liver impairment and other serious liver problems.
