A comparative investigation of contraceptive reliability, cycle control and tolerance of two monophasic oral contraceptives containing either drospirenone or desogestrel

The combination of 30 microg ethinylestradiol combined with 3 mg drospirenone provides effective oral contraception and good cycle control, and is well tolerated. Ethinylestradiol/drospirenone had a more favorable effect on body weight than ethinylestradiol/desogestrel, with the mean body weight remaining lower than baseline for the majority of the women.
