Concomitant use of vemurafenib with agents metabolized by CYP3A4 with narrow therapeutic windows is not recommended. If co-administration cannot be avoided, it needs to be considered that vemurafenib may decrease plasma concentrations of CYP3A4 substrates and thereby their efficacy may be impaired. On this basis, the efficacy of contraceptive pills metabolized by CYP3A4 used concomitantly with vemurafenib might be decreased. Dose adjustments for CYP3A4 substrates with narrow therapeutic window may be considered, if clinically indicated (see sections 4.4 and 4.6). In a clinical trial, co-administration of vemurafenib decreased the AUC of midazolam (CYP3A4 substrate) by an average 39% (maximum decrease up to 80%).
