Contraindications
Loss of virologic response or resistance with rifampin, St. John's wort. Drugs metabolized by CYP3A that may cause serious events if blood levels are elevated (eg, cisapride, ergots, pimozide, midazolam, triazolam).
Precautions
Suspend if pancreatitis occurs. History of, or risk factors for, pancreatitis (eg, elevated triglycerides). Hepatic impairment. Hepatitis. Diabetes. Monitor: lipids at baseline then periodically, ALT/AST in liver disease, for hyperglycemia or fat redistribution, hemophiliacs (for spontaneous bleed). Elderly. Pregnancy (Cat.C). Nursing mothers: not recommended.
Interactions
See Contraindications. Lovastatin, simvastatin, St. John's wort, rifampin, voriconazole: not recommended. Potentiates sildenafil, vardenafil, tadalafil (reduce dose of these), statins metabolized by CYP3A (eg, atorvastatin), fluticasone (avoid). Avoid oral soln with metronidazole, disulfiram. Monitor other antiretrovirals, warfarin. Increases levels of antiarrhythmics, dihydropyridine, calcium channel blockers, immunosuppressants (monitor); ketoconazole, itraconazole (avoid high doses); rifabutin (reduce rifabutin dose and monitor); clarithromycin (reduce clarithromycin dose in renal dysfunction), trazodone (reduce trazodone dose).

Lopinavir levels decreased by anticonvulsants (eg, carbamazepine, phenobarbital, phenytoin), dexamethasone, efavirenz, nevirapine. Lopinavir levels may be increased by delavirdine, CYP3A inhibitors. May decrease zidovudine or abacavir levels. See literature.
