Effect of other medicinal products on lenvatinib: Interaction with other medicinal products and other forms of interaction below are relevant to the use of lenvatinib monotherapy. Population pharmacokinetic analysis demonstrated that lenvatinib does not significantly affect the pharmacokinetics of either everolimus or pembrolizumab. When using lenvatinib in combination with everolimus or pembrolizumab, also refer to the manufacturer's prescribing information for everolimus or pembrolizumab.
Chemotherapeutic agents: Concomitant administration of lenvatinib, carboplatin, and paclitaxel has no significant impact on the pharmacokinetics of any of these 3 substances.
Effect of lenvatinib on other medicinal products: A clinical drug-drug interaction (DDI) study in cancer patients showed that plasma concentrations of midazolam (a sensitive CYP3A and Pgp substrate) were not altered in the presence of lenvatinib. No significant drug-drug interaction is therefore expected between lenvatinib and other CYP3A4/Pgp substrates.
Oral contraceptives: It is currently unknown whether lenvatinib may reduce the effectiveness of hormonal contraceptives, and therefore women using oral hormonal contraceptives should add a barrier method (see Use in Pregnancy & Lactation).
