SELZENTRY is contraindicated in patients with severe renal impairment or ESRD (creatinine clearance [CrCl] less than 30 mL per minute) who are concomitantly taking potent CYP3A inhibitors or inducers [see Warnings and Precautions ( 5.3 )].

SELZENTRY is contraindicated in patients with severe renal impairment or end-stage renal disease (ESRD) (creatinine clearance [CrCl] less than 30 mL per minute) who are concomitantly taking potent CYP3A inhibitors or inducers.

In the Phase 2b/3 trial in treatment‑naive adult subjects, the incidence of AIDS-defining Category C events when adjusted for exposure was 1.8 for SELZENTRY compared with 2.4 for efavirenz per 100 patient‑years of exposure.

• If patients with severe renal impairment or ESRD receiving SELZENTRY (without concomitant CYP3A inducers or inhibitors) experience postural hypotension, the dose of SELZENTRY should be reduced from 300 mg twice daily to 150 mg twice daily.

• Coadministration with CYP3A inhibitors, including protease inhibitors (except tipranavir/ritonavir), will increase the concentration of SELZENTRY.
