Rare Occurrence of Serious Liver Disease in Some Patients with Use of Hepatitis C Medicines

August 28, 2019

The FDA has issued a warning about rare occurrences of serious liver disease in some patients with the use of the following hepatitis C medicines:

  • Mavyret (Glecaprevir and Pibrentasvir)
  • Zepatier (Elbasvir and Grazoprevir)
  • Vosevi (Sofosbuvir, Velpatasvir, and Voxila)

The FDA observed 63 reported cases of worsening liver function, (liver decompensation), in the FAERS adverse event reporting database. A majority of these cases were reported among patients who already had moderate or severe liver impairment prior to starting HCV antiviral therapy. In addition, some cases had other significant preexisting risk factors such as hepatocellular carcinoma, alcohol abuse, or serious medical illnesses associated withserious liver problems.

Mevyret, Zepatier, and Vosevi are indicated for the treatment of HCV in patients with no or mild liver impairment(defined by Child-Pugh score of A). Patients with moderate or severe liver impairment (Child-Pugh score of B or C) should not be treated with these three medications.
