Birth Control Pills May Raise Lupus Risk
Researchers Say Pill May Interact With Genetic Predisposition to Slightly Boost Lupus Risk
Oral Contraceptives and Lupus: Study Statistics, Perspective continued...
"The benefits of the pill are certainly very high," he says. "Compared to these risks [of lupus], our study makes it clear that with the newer pills, at the lower doses, that in essence this risk is almost nonexistent."
The study suggests that "the risk for oral contraceptives causing lupus is there but it's small," says Bevra Hahn, MD, chief of rheumatology and arthritis at the University of California Los Angeles David Geffen School of Medicine and a member of the medical-scientific advisory council for the Lupus Foundation. .
The finding about higher-dose pills boosting the risk of lupus more than low-dose pills is new, Hahn says. The take-home point? "The lower the estrogen content you can manage, the less likely [the pill] is to cause lupus in someone who doesn't have it," she says.
''There is no well-established link between combined oral contraceptive use and the development of lupus," says Rose Talarico, a spokeswoman for Bayer HealthCare Pharmaceuticals, based in Wayne, N.J. which makes two types of birth control pills.
But, she adds, the labeling for combined oral contraceptives does caution that persistent lupus can be made worse with use of the pills.
Many lower-dose options are available these days, she says. Bayer, for instance, makes Yaz and Yasmin; both have 30 micrograms or less of estrogen, she says.
