Hepato-biliary disorders: isolated asymptomatic hyperbilirubinaemia (total bilirubin ≥ 2.5 mg/ dl, 43 mcmol/ l), reported predominantly as elevated indirect bilirubin and rarely associated with elevations in ALT, AST, or alkaline phosphatase, has occurred in approximately 14% of patients treated with CRIXIVAN alone or in combination with other antiretroviral agents.
