Miconazole, zinc oxide, and petrolatum

Drug-drug interaction studies were not conducted. Women who take a warfarin anticoagulant and use a miconazole intravaginal cream or suppository may be at risk for developing an increased prothrombin time, international normalized ratio (INR), and bleeding. The potential for this interaction between warfarin and VUSION is unknown.

8.1 Pregnancy Risk Summary There are no available data on VUSION Ointment use in pregnant women to inform a drug‑associated risk for adverse developmental outcomes. In animal reproduction studies, prolonged gestation, increased number of resorptions, and decreased numbers of live young were observed after oral administration of miconazole nitrate during organogenesis to pregnant rats and rabbits. No comparisons of animal exposure with human exposure may be calculated due to minimal systemic exposure in humans after topical administration of VUSION [see Clinical Pharmacology (12.3) ]. In the U.S.

general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Miconazole nitrate administration has been shown to result in prolonged gestation and decreased numbers of live young in rats and in increased number of resorptions and decreased number of live young in rabbits at oral doses of 100 mg/kg/day and 80 mg/kg/day.
