  • At standard doses, coadministration of efavirenz and voriconazole is contraindicated[DHHS ART]
  • Etravirine and voriconazole concentrations increase during coadministration; thus, although no dose adjustment is currently necessary, caution is recommended in combining these drugs and therapeutic drug monitoring should be considered when they are coadministered[DHHS ART]
