NuvaRing and Weight
Good news for NuvaRing users:
The NuvaRing contraceptive appears to be as effective in women who weigh more than 89.9 kg (198 lbs.) as in women who weigh less, Carolyn Westhoff, M.D., reported in a poster presentation at the annual meeting of the American College of Obstetricians and Gynecologists.
Previous reports have shown higher incidence of pregnancies with other hormonal contraceptive methods among patients weighing more than 89.9 kg. No causal relationship between body weight and pregnancy risk has been shown, said Dr. Westhoff of Columbia University in New York.
