OBJECTIVES: To compare the adverse effects, cycle control, and metabolic effects of NuvaRing and a combined oral contraceptive (COC).
METHODS: Women seeking contraception received NuvaRing (n = 300) or a COC (n = 300) for 12 cycles in a randomized, open-label trial.
RESULTS: The total number of women with adverse effects did not differ significantly between the 2 groups. Leucorrhea, vaginitis, decreased libido, and ring-related problems were more common with NuvaRing, whereas weight increase, acne, and emotional lability were more common with the COC. Breakthrough bleeding occurred in 11.3% of women receiving NuvaRing and in 14.7% of women receiving the COC; 2.1% and 2.9% of women, respectively, had no withdrawal bleeding. Differences in blood pressure, blood sugar levels, lipid profile, liver enzyme activity, and anticoagulant activity were not statistically significant, with the exception of low-density lipoprotein levels measured at 6 and 12 months, which were significantly lower in the NuvaRing group than in the COC group.
CONCLUSIONS: NuvaRing is a good alternative to a COC. It is associated with a slightly reduced incidence of breakthrough bleeding and there were no clinically relevant adverse effects or changes in blood pressure, blood sugar levels, lipid profile, or anticoagulant activity when compared with the COC.
