Contraception - Management
When can the progestogen-only implant be inserted?
- Provided that it is reasonably certain that the woman is not pregnant, the progestogen-only implant can be inserted at any time, but the need for additional contraception varies.
- First implant, or switching from a hormonal method of contraception:
- Ideally insert within days 1–5 of the menstrual period.
- If inserted outside this time, or if the woman is amenorrhoeic, additional contraception is needed for 7 days.
- If switching from a progestogen-only injectable, the implant should be inserted no later than the time when the next injection is due.
- Switching from a copper intrauterine device (IUD) or a levonorgestrel-releasing intrauterine system (LNG-IUS):
- Insert the implant and remove the IUD or LNG-IUS at least 7 days later.
- Postpartum:
- Ideally insert on day 21 for immediate contraceptive protection.
- If started after day 21, additional contraception is needed for 7 days, unless she is fully breastfeeding.
- Post-abortion or post-miscarriage:
- If inserted on the same day (for abortion, whether induced or spontaneous, at < 24 weeks' gestation) no additional contraceptive method is required.
- If started more than 5 days days after abortion or miscarriage, an additional contraceptive method is required for 7 days.
