7.2 Use of Other Antiretroviral Drugs after Discontinuation of CABENUVA Residual concentrations of cabotegravir and rilpivirine may remain in the systemic circulation of patients for prolonged periods (up to 12 months or longer). 7.3 Potential for Other Drugs to Affect CABENUVA Refer to the prescribing information for VOCABRIA (cabotegravir) and EDURANT (rilpivirine) for additional drug interaction information related to oral cabotegravir and oral rilpivirine, respectively. Cabotegravir Cabotegravir is primarily metabolized by UGT1A1 with some contribution from UGT1A9.

( 7.1 ) • Drugs that induce uridine diphosphate glucuronosyltransferase (UGT)1A1 may decrease the plasma concentrations of cabotegravir. Prior to initiating dosing with VOCABRIA, the prescribing information for CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) or APRETUDE should be consulted to ensure use of CABENUVA or APRETUDE will be appropriate for either the treatment of HIV-1 infection or HIV-1 PrEP, respectively. 7.2 Potential for Other Drugs to Affect VOCABRIA Cabotegravir is primarily metabolized by UGT1A1 with some contribution from UGT1A9.

7.4 Drugs without Clinically Significant Interactions with Cabotegravir Based on drug interaction study results, the following drugs can be coadministered with cabotegravir (non-antiretrovirals) or given after discontinuation of cabotegravir (antiretrovirals and non-antiretrovirals) without a dose adjustment: etravirine, midazolam, oral contraceptives containing levonorgestrel and ethinyl estradiol, and rilpivirine [see Clinical Pharmacology ( 12.3 )] .
