CYP3A4 Substrates: CYP3A4 Inducers may decrease the serum concentration of CYP3A4 Substrates.
Efavirenz: Reverse Transcriptase Inhibitors (Non-Nucleoside) may increase the serum concentration of Efavirenz.
HMG-CoA Reductase Inhibitors (Statins): Etravirine may decrease the serum concentration of HMG-CoA Reductase Inhibitors (Statins).
Phosphodiesterase 5 Inhibitors: Etravirine may decrease the serum concentration of Phosphodiesterase 5 Inhibitors.
