See Contraindications. Salmeterol, boceprevir, simeprevir, ombitasvir/parataprevir/ritonavir and dasabuvir: not recommended. Avoid oral soln with metronidazole, disulfiram. Potentiates statins metabolized by CYP3A; use atorvastatin with caution and at the lowest necessary doses; do not exceed rosuvastatin 10mg daily. Potentiates sildenafil, vardenafil, tadalafil (reduce dose of these); avanafil, fluticasone (avoid). Potentiates fentanyl, parenteral midazolam; monitor. Potentiates anticancer agents (eg, vincristine, vinblastine, dasatinib, nilotinib); may need dose adjustment (see full labeling). Risk of tumor lysis syndrome with venetoclax. Concomitant colchicine (see full labeling). Potentiates bosentan (see full labeling). Increases levels of antiarrhythmics (eg, amiodarone, bepridil, systemic lidocaine, quinidine), dihydropyridine CCBs, immunosuppressants (monitor); ketoconazole, itraconazole (avoid high doses), isavuconazonium sulfate (caution); bedaquiline (use only if benefit outweighs the risk); rifabutin (reduce rifabutin dose and monitor); clarithromycin (reduce clarithromycin dose in renal dysfunction), trazodone (reduce trazodone dose), maraviroc (give max maraviroc 150mg twice daily), quetiapine (reduce dose). Monitor other antiretrovirals, warfarin. Avoid concomitant rivaroxaban; increased bleeding risk.

Lopinavir levels decreased by anticonvulsants (eg, carbamazepine, phenobarbital, phenytoin), efavirenz, nevirapine. Lopinavir levels may be increased by delavirdine, CYP3A inhibitors. Antagonized by corticosteroids (eg, oral dexamethasone, betamethasone, budesonide); consider alternatives. May decrease lamotrigine, valproate, zidovudine or abacavir levels. Give didanosine 1 hour before or 2 hours after. Avoid concomitant with other drugs that prolong the QT interval. See full labeling.
