The Nexplanon is a birth control implant that is placed in the upper arm by a doctor and is a very safe form of birth control. It’s approved by the FDA to prevent pregnancy for three years, and it’s the most effective form of birth control—over 99.9% effective! The implant is a thin, flexible device. Before inserting it, your doctor will inject a small amount of numbing medication in the placement site on your arm, so the placement should not be painful. The most common side effect that women who receive a birth control implant have is irregular bleeding. About one third of users will have lighter periods, one third will have heavier periods, and one third will have the same amount of bleeding as before. Spotting between periods can also occur. Less commonly, some women experience headaches, mood swings, weight gain, and acne. If you decide you do not like the Nexplanon, the device can be removed at any time by a doctor. Again, your doctor will inject numbing medication at one end of the contraceptive device, make a small cut in your arm, and remove the device. Having this device will not affect your future ability to become pregnant. You should start another form of birth control immediately after removal to prevent pregnancy.
