Nervous system

Very common (10% or more): Headache (up to 17%)

Rare (less than 0.1%): Transient ischemic attack[Ref]


Very common (10% or more): Pruritus (up to 17.3%)

Frequency not reported: Rash, erythematous rash

Postmarketing reports: Angioedema[Ref]


Very common (10% or more): Elevated bilirubin (up to 17%)

Common (1% to 10%): Elevated total bilirubin

Uncommon (0.1% to 1%): Direct hyperbilirubinemia

Frequency not reported: Jaundice

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]


Very common (10% or more): Fatigue (up to 16%)

Common (1% to 10%): Asthenia[Ref]


Very common (10% or more): Nausea (up to 12%)
