Key takeaways
Nexplanon (etonogestrel) and Paragard (copper IUD) are both highly effective birth control options, but they work in different ways and have distinct features. Nexplanon is a small implant placed under the skin of your upper arm that releases a hormone called etonogestrel and prevents pregnancy for up to 3 years. In contrast, Paragard is a hormone-free intrauterine device (IUD) that releases copper into your uterus and can prevent pregnancy for up to 10 years. Nexplanon can cause side effects like irregular vaginal bleeding, headaches, and weight gain, while Paragard may lead to heavier or longer menstrual periods and spotting between periods. Nexplanon is inserted and removed through a minor procedure in your arm, whereas Paragard is placed and removed by a healthcare provider directly in your uterus. Both methods require a prescription and do not protect against sexually transmitted infections (STIs). If you prefer a hormone-free option and longer-lasting protection, Paragard might be more suitable, but if you want a shorter-term solution, Nexplanon could be the better choice.
