Noninteracting drugs include tipranavir/ritonavir, nevirapine, raltegravir, all NRTIs, and enfuvirtide

Also, all other medications that are not potent CYP3A inhibitors or inducers

Potent CYP3A inhibitors (with or without a potent CYP3A inducer)

10 kg to < 20 kg: 50 mg PO BID

20 kg to < 30 kg: 75 mg (tablet) or 80 mg (oral solution) PO BID

30 kg to < 40 kg: 100 mg PO BID

≥40 kg: 150 mg PO BID

Potent CYP3A inhibitors include protease inhibitors (except tipranavir/ritonavir), delavirdine, elvitegravir/ritonavir, ketoconazole, itraconazole, clarithromycin, and other potent CYP3A inhibitors (eg, nefazodone, telithromycin)

Potent CYP3A inducers (without a potent CYP3A inhibitor)
