Efficacy, cycle control, and side effects of low- and lower-dose oral contraceptives: a randomized trial of 20 micrograms and 35 micrograms estrogen preparations. Contraception. 1999 Dec;60(6):321-9 Authors: Rosenberg MJ, Meyers A, Roy V Estrogen content represents a tradeoff between cycle control and side effects, but few direct comparisons of 20 and 30/35 micrograms preparations are available. To address this issue, we conducted a randomized, open-label multicenter clinical trial comparing Alesse (20 micrograms ethinyl estradiol [EE]), Mircette (20 micrograms EE), and Ortho Tri-Cyclen (35 micrograms EE) among 463 OC starters or switchers. Bloating, breast tenderness, and nausea were approximately 50% more common in women using 35 micrograms EE as compared to 20 micrograms EE preparations. Cycle control was similar in all products, although during the first two cycles among starters; users of Mircette and Ortho Tri-Cyclen (Tri-Cyclen) exhibited better cycle control than Alesse users. Discontinuation and pregnancy rates were not significantly higher in 35 micrograms EE users. PMID: 10715366 [PubMed - indexed for MEDLINE] Read more...             |
