I was told by a friend that this isn't a type of birthcontrol because her sister got it & is now pregnant???
The only birth control method that is 100% effective is abstinance. Most forms of birth control offer a good degree of protection but none are 100% if you are sexually active. IMPLANON™ (etonogestrel implant) is indicated for women for the prevention of pregnancy. IMPLANON™ (etonogestrel implant) is a long-acting (up to 3 years), reversible, contraceptive method. IMPLANON™ (etonogestrel implant) must be removed by the end of the third year and may be replaced by a new IMPLANON™ (etonogestrel implant) at the time of removal, if continued contraceptive protection is desired.
In clinical trials involving 923 subjects and 1,854 women-years of IMPLANON™ (etonogestrel implant) use, the total exposure in 28-day cycles by year was
Year 1: 10,867 cycles
Year 2: 8,595 cycles
Year 3: 3,492 cycles
The clinical trials excluded women who
Weighed more than 130% of their ideal body weight
Were chronically taking medications that induce liver enzymes
Among women aged 18-35 years of age at entry, six pregnancies during 20,648 cycles of use were reported. Two pregnancies occurred in each of Years 1, 2 and 3. Each conception was likely to have occurred shortly before or within two weeks after IMPLANON™ (etonogestrel implant) removal. With these six pregnancies, the cumulative Pearl Index was 0.38 pregnancies per 100 women-years of use.
The efficacy of IMPLANON™ (etonogestrel implant) does not depend on patient self-administration. IMPLANON™ (etonogestrel implant) may be less effective in women who are overweight or who are taking medications that induce liver enzymes.
The effectiveness of IMPLANON™ (etonogestrel implant) in overweight women has not been defined because women who weighed more than 130% of their ideal body weight were not studied. However, serum concentrations of ENG are inversely related to body weight and decrease with time after insertion. It is therefore possible that with time IMPLANON™ (etonogestrel implant) may be less effective in overweight women, especially in the presence of other factors that decrease etonogestrel concentrations such as concomitant use of hepatic enzyme inducers.
If IMPLANON™ (etonogestrel implant) is inserted correctly, your chance of getting pregnant is very low (less than 1 pregnancy per 100 women who use IMPLANON for one year). It is not known if IMPLANON™ (etonogestrel implant) is as effective in very overweight women because studies did not include many overweight women.
IMPLANON is comparable to implants, IUD's, injections, sterilization, the Pill, skin patches and the vaginal ring with hormones. It is actually slightly more effective than the Pill, patches and the vaginal ring. All forms of birth control have risk of pregnancy and none are without side effects. It takes careful consideration of your lifestyle and how you react to each method to decide what is right for you. Any birth control you name-someone will know of someone who became pregnant while using it. Again, the ONLY 100% effective birth control is abstinance (or to not have sex in the first place).
