ESRD with hemodialysis in treatment-experienced or hepatic impairment: not recommended. Preexisting or at high risk for renal disease: consider alternatives. Cardiac conduction abnormalities; consider ECG monitoring if preexisting marked 1st -degree AV block or 2nd/3rd -degree AV block. Consider interruption or discontinuation if nephrolithiasis or cholelithiasis occurs. Liver disease, hepatitis B and/or C, marked elevations in transaminases: monitor LFTs before and during therapy. Consider alternatives if jaundice or scleral icterus occurs. Diabetes. Hemophilia. Elderly. Pregnancy (use alternative therapy), nursing mothers: not recommended.

EVOTAZ Classification:

HIV-1 protease inhibitor + CYP3A inhibitor.
