While direct clinical evidence is still developing, the potential for interaction exists
The team can review potential benefits, limitations, risks, and alternatives to help patients make informed decisions about supportive therapies

These changes are unlikely to be clinically significant as all subjects had etravirine concentrations well above the median protein binding adjusted EC50 of 4 ng/mL (concentration to inhibit 50% of viral replication in vitro).15 Moreover, the reductions in etravirine concentration are comparable to those seen in clinical trials when etravirine was coadministered with darunavir/ritonavir.16 High rates of efficacy were described when etravirine 200 mg twice daily and darunavir/ritonavir were coadministered in patients with extensive resistance, despite a 30% decrease in etravirine pharmacokinetic parameters (compared with historical controls).17 In recent large randomized trials, twice-daily etravirine resulted in additional antiviral effect versus placebo despite the concomitant administration of a boosted protease inhibitor.18,19 Furthermore, in a pooled analysis of these trials, no association between etravirine pharmacokinetics and 48-week efficacy (viral load 90%

Use is generally guided by a clinician, who may recommend how often to apply it, how it fits alongside other skincare products, and how to tailor it to specific skin concerns
