how effective is nexplanon

Nexplanon is highly effective for birth control, with an effectiveness rate of over 99%. Specifically, its pregnancy prevention rate is about 99.95% in the first year of use and approximately 99.9% overall, making it one of the most reliable contraceptive methods available. This effectiveness is due to its mechanism of stopping ovulation, thickening cervical mucus, and altering the uterine lining, as well as the fact that it doesn't rely on user actions once inserted. The implant can remain effective for up to 3 years (FDA-approved) and may even last up to 5 years based on some research. It has the advantage of minimal user error compared to daily pills or other methods requiring regular action. Real-world studies also support its high effectiveness with very low pregnancy rates in typical use. However, Nexplanon does not protect against sexually transmitted infections (STIs), so using barrier methods like condoms is recommended for STI prevention. Common side effects include changes in menstrual bleeding patterns, mood swings, weight gain, and headaches, but these vary among users. In summary, Nexplanon is over 99% effective at preventing pregnancy, making it one of the most effective birth control options available today.
