एल्विटेग्राविर, कोबिसिस्टैट, एमट्रिसिटाबिन और टेनोफोविर और नॉरएल्जेस्ट्रोमिन और एथिनिल एस्ट्राडियोल का इंटरैक्शन

CYP3A4 inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase plasma hormone concentrations.

The potential risks and benefits associated with coadministration of norgestimate/ethinyl estradiol with GENVOYA should be considered, particularly in patients who have risk factors for these events.

Hormonal Contraceptives: drospirenone/ethinyl estradiol levonorgestrel norgestimate/ethinyl estradiol ↑ drospirenone ↑ norgestimate ↑ levonorgestrel ↓ ethinyl estradiol Additional or alternative non-hormonal forms of contraception should be considered when estrogen based contraceptives are coadministered with GENVOYA.

The effect of GENVOYA on other hormonal contraceptives (e.g., contraceptive patch, contraceptive vaginal ring, or injectable contraceptives) or oral contraceptives containing progestogens other than drospirenone, levonorgestrel, or norgestimate has not been studied; therefore, alternative (non-hormonal) methods of contraception can be considered.
