Drug Interactions
Decreased bioavailability with CYP3A4 inducers (e.g. rifampicin, carbamazepine, phenobarbital, phenytoin, griseofulvin, spironolactone). Increased bioavailability with CYP3A4 inhibitors (e.g. ketoconazole, ritonavir). May inhibit ciclosporin metabolism leading to increase plasma ciclosporin concentrations and risk of toxicity. May diminish the therapeutic effect of antidiabetic agents. May diminish the therapeutic effect with other vaginal products (e.g. antifungal agents).
