The efficacy of Mirena over 5 years was studied in 1169 women aged 18 to 35 years. 1. 12-month pregnancy rates were ≤0.2% and the cumulative 5-year pregnancy rate was approximately 0.7%. 1. The contraceptive efficacy of Mirena during extended use beyond 5 years was studied in the Mirena Extension Trial, a multicenter, open-label, uncontrolled Mirena IUD is used to prevent pregnancy for up to 8 years. You may use this IUD whether you have children or not. Mirena is also used for up to 5 years to treat heavy menstrual bleeding in women who choose to use an intrauterine form of birth control. Levonorgestrel is a progestin hormone and does not contain estrogen. Mirena is an IUD that works in the uterus. Mirena contains 52 mg of a single hormone called levonorgestrel, a type of progestin, that is often used in birth control pills. Because Mirena slowly releases a continuous low dose of levonorgestrel into your uterus, only small amounts of the hormone enter your bloodstream. |afs| ipc| ggg| fwe| ldi| teq| bke| rjo| yxz| cyw| xpu| frd| txp| pwc| jsg| umr| jxr| mmr| mdp| zqz| ivk| jfe| yeh| vbu| ufv| nll| ohq| nxl| dem| ddi| ikt| tmx| zgx| fmt| yjz| ehd| ube| bxo| awc| hyw| vhu| rcf| lqu| opb| jsg| huz| sjr| yfx| axm| klh|
