The birth control implant is a highly effective form of birth control. The rod gets placed into your arm for three years, so it gives you the same contraceptive effectiveness for those three years. This birth control implant is very safe as it prevents pregnancy, and because it doesn't have any estrogen, you're not worried about the side effects associated with that.
As far as effectiveness, because it does not require daily motivation and it can stay in your arm for three years, it is well over 99% effective. This is an excellent birth control option for patients who do not want to be pregnant for a three-year period. When you remove the implant, it does give you immediate return to fertility.
