Vertical arrow pointing up showing the effectiveness of Progestin-Only Injectables. The bottom of the arrow is less effective and top of the arrow is more effective. A black bar is at the top of the arrow.One of the most effective and long-lasting methods:

  • Far less than 1 pregnancy per 100 women using implants over the first year (1 per 1,000 women). This means that 999 of every 1,000 women using implants will not become pregnant. Less than 1 pregnancy per 100 women over the duration of use.
  • A small risk of pregnancy remains beyond the first year of use and continues as long as the woman is using implants.
  • For heavier women, the effectiveness of Jadelle and Levoplant may decrease near the end of the duration of use stated on the label. These users may want to replace their implants sooner (see Question 9).

Return of fertility after implants are removed: No delay

Protection against sexually transmitted infections (STIs): None
