I prescribe a lot of birth control pills and many NuvaRings for my patients. As you might imagine most women like their method and have few side effects. Women love the convenience of the NuvaRing and find it easy to use. Many providers, (myself included) like the fact that it has the lowest circulating dose of estradiol (15 mcg). The NuvaRing is a great option for women with menstrual migraines, acne, headaches, & with PMS.
Within the last month, I have received 3 separate calls from women who wanted to stop using the NuvaRing because of much lower sex drive. One said, that she knows why it's such great contraception, because she has absolutely no interest in sex. Another found that her moods were depressed and she was much more fatigued. Another experienced hot flashes and night sweats on it.
I searched the literature and the package insert and sure enough lowered libido is one of the side effects. This can happen with any form of hormonal birth control, not just the NuvaRing. Yet, I suspect that the lowered estrogen dose may make this more common in some women.
The longer I practice, the more I notice individual variation among women. We can all take the exact same dose and yet, each will have a different experience.
Bottom line, if you are having side effects from any medication, give your provider a call and find a better alternative.
