Implanon Insertion and Management

Timing of Insertion

  • Implanon can be inserted at any time if it is reasonably certain that the woman is not pregnant, as recommended by the Centers for Disease Control and Prevention 1
  • For postpartum women (not breastfeeding) who are ≥21 days postpartum and have not experienced return of menstrual cycles, Implanon can be inserted immediately, according to the Centers for Disease Control and Prevention 1
  • The Centers for Disease Control and Prevention supports immediate postpartum insertion of implants as a safe and effective practice that removes barriers to care 2, 3

Need for Back-Up Contraception

  • If the spotting represents the return of menstrual cycles and it has been >7 days since menstrual bleeding started, the woman needs to use additional contraceptive protection for the next 7 days after insertion, as recommended by the Centers for Disease Control and Prevention 1
  • If inserting during the first 5 days of menstrual bleeding, no additional contraceptive protection is needed, according to the American Academy of Pediatrics 4

Counseling About Bleeding Patterns

  • Before implant insertion, provide counseling about potential changes in bleeding patterns, as recommended by the Centers for Disease Control and Prevention 5
  • Enhanced counseling about expected bleeding patterns has been shown to reduce discontinuation rates, according to the Centers for Disease Control and Prevention 5

Management of Bleeding Irregularities

  • If irregular bleeding persists and becomes unacceptable to the patient, treatment options include NSAIDs for short-term treatment (5-7 days), as recommended by the Centers for Disease Control and Prevention 5
  • Hormonal treatment with low-dose combined oral contraceptives or estrogen for short-term treatment (10-20 days) if medically eligible, is also an option, according to the Centers for Disease Control and Prevention 5

Important Considerations

  • Implanon is highly effective with typical and perfect use failure rates of less than 1%, as reported by the American Academy of Pediatrics 2, 3
  • No routine follow-up visit is required after implant insertion, as recommended by the Centers for Disease Control and Prevention 5
