Management of Breakthrough Bleeding During Extended Therapy Use With NuvaRing®

Hormonal contraception is undergoing a change away from a 21/7 day regimen where a woman utilizes a combination estrogen and progestin therapy for 21 days followed by 7 days of a hormone-free interval (HFI). It is well documented that women may experience a higher incidence of mood changes, headaches and cramping that begin prior to and during this 7 day HFI. By reducing the HFI and extending the active combination contraceptive therapy, it is hoped that women will experience greater satisfaction with their contraceptive regimen and will experience fewer negative side effects associated with a HFI. The most common reason for discontinuation of an extended contraception regimen is irregular bleeding. The purpose of this research study is to evaluate the best way to manage this breakthrough spotting and bleeding. Ease of use and acceptability of a flexible regimen of NuvaRing will also be evaluated. A comparison of cyclic mood symptoms, pelvic pain, and headaches will be made between a standard 21/7 regimen and an extended regimen. The contraceptive ring used in this study contains both an estrogen (ethinyl estradiol) and a progestin (etonogestrel). These are synthetic (man-made) hormones. The amount of ethinyl estrogen released into the bloodstream each day is 120mcg and the amount of etonogestrel is 150mcg. The NuvaRing®, by Organon, is FDA approved for contraception, but is not approved for use in an extended regimen. Therefore its use in this study is considered investigational.
