Concomitant Drug Class: Drug Name Effect on Concentration of Dolutegravir and/or Concomitant Drug Clinical Comment HIV-1 Antiviral Agents Non-nucleoside reverse transcriptase inhibitor: Etravirine a ↓Dolutegravir Use of TIVICAY or TIVICAY PD with etravirine without coadministration of atazanavir/ritonavir, darunavir/ritonavir, or lopinavir/ritonavir is not recommended.
Etravirine significantly reduced plasma concentrations of dolutegravir, but the effect of etravirine was mitigated by coadministration of lopinavir/ritonavir or darunavir/ritonavir and is expected to be mitigated by atazanavir/ritonavir ( Table 8 ) [see Drug Interactions ( 7.3 ), Clinical Pharmacology ( 12.3 )] .
…dolutegravir exposures observed in INSTI-experienced patients (with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance [see Microbiology ( 12.4 )] ) upon coadministration with certain inducers may result in loss of therapeutic effect and development of resistance to TIVICAY or other coadministered antiretroviral agents.

Table 4: Significant Drug Interactions Concomitant Drug Class: Drug Name Effect on Concentration of Etravirine or Concomitant Drug Clinical Comment ↑ = increase; ↓ = decrease; ↔ = no change HIV-antiviral agents: integrase strand inhibitors dolutegravir The interaction between Etravirine and the drug was evaluated in a clinical study.
All other drug interactions shown are predicted. ↓ dolutegravir ↔ etravirine Etravirine significantly reduced plasma concentrations of dolutegravir.
Using cross - study comparisons to historical pharmacokinetic data for etravirine, dolutegravir did not appear to affect the pharmacokinetics of etravirine. dolutegravir/darunavir /ritonavir ↓ dolutegravir ↔ etravirine The effect of etravirine on dolutegravir plasma concentrations was mitigated by co-administration of darunavir/ritonavir or lopinavir/ritonavir,…
Dolutegravir should only be used with Etravirine when co-administered with atazanavir/ritonavir, darunavir/ritonavir, or lopinavir/ritonavir. dolutegravir/lopinavir /ritonavir ↔ dolutegravir ↔ etravirine HIV-antiviral agents: non-nucleoside reverse transcriptase inhibitors (NNRTIs) efavirenz nevirapine ↓ etravirine Combining two NNRTIs has not been shown to be…
Stevens-Johnson syndrome was reported in 1.1% (2/177) of pediatric patients less than 18 years of age receiving Etravirine in combination with other HIV-1 antiretroviral agents in an observational study.
