Some cases have resulted in fulminant hepatitis, hepatic failure, and death. Monitor HCV/HBV coinfected patients for hepatitis flare or HBV reactivation during HCV treatment and post-treatment follow-up. Initiate appropriate patient management for HBV infection as clinically indicated.

The most common side effects reported in HCV-infected patients with compensated cirrhosis (Child-Pugh A) were fatigue, headache, nausea, diarrhea, and pruritus. The most common side effects reported in HCV-infected patients with severe renal dysfunction were pruritus, fatigue, nausea, asthenia, and headache. The most common side effects reported in HCV/HIV-1-coinfected patients were fatigue, nausea, and headache. The most common side effects reported in HCV-infected patients with liver or kidney transplant were headache, fatigue, nausea, and pruritus. The most common side effects reported in HCV-infected patients who inject drugs (currently/recently [within the last 12 months prior to therapy]) were fatigue, headache, diarrhea, and nausea. The most common side effects reported in HCV-infected patients with concomitant use of medication-assisted treatment for opioid use disorder were headache, fatigue, nausea, and diarrhea.[Ref]
Very common (10% or more): Headache (up to 17%)
Very common (10% or more): Pruritus (up to 17.3%)
Very common (10% or more): Elevated bilirubin (up to 17%)
Common (1% to 10%): Elevated total bilirubin

Postmarketing reports: Hepatic decompensation, hepatic failure[Ref]
Elevated total bilirubin (at least 2 times the upper limit of normal [2 x ULN]) was reported in 3.5% of patients; such elevations were seen in 1.2% of patients across phase 2 and 3 trials and were related to glecaprevir-mediated inhibition of bilirubin transporters and metabolism. Bilirubin elevations were asymptomatic, transient, and generally occurred early during therapy; these elevations were mainly indirect and not associated with ALT elevations.
In patients with compensated cirrhosis (Child-Pugh A), 17% reported early, transient postbaseline bilirubin elevations above the ULN; these elevations were normally less than 2 x ULN, usually occurred with the first 2 weeks of therapy, and resolved with continued therapy. Patient with compensated cirrhosis and elevated bilirubin did not have concomitant increases in ALT/AST or signs of liver decompensation/failure; these laboratory events did not result in discontinuation of therapy. Few patients reported jaundice or ocular icterus and total bilirubin levels decreased after completion of therapy.[Ref]
