HFGP Consent Form for Implanon Procedure

Patient Details


The insertion of IMPLANON NXT® involves a small plastic implant containing the hormone progestogen being inserted underneath the skin of the upper inner arm to act as a contraceptive against pregnancy for up to three years.

  • It is a highly effective form of contraception and is an alternative to the pill, IUD’s, Depo injections and sterilisation. 

  • It is placed under the skin in the non-dominant arm. It is easily palpable once placed so that it can be easily removed. It may need US guidance if removal proves difficult. Removal and insertion may leave temporary bruising and a small scar

  • The slow progesterone release acts to inhibit ovulation and hence is a contraceptive. It is effective immediately if inserted in the first few days of menstrual cycle. 

  • It must be removed after 3 years and it is your responsibility to ensure that it is removed after that time, as it will no longer be effective and pregnancy may follow. A record of date of insertion will be kept on file at the surgery.

  • The best time to have Implanon inserted is in the first few days of your period.  If not inserted at this time, you will need to do a pregnancy test at time of insertion and again 4 weeks later. 

  • Implanon is safe to use as postnatal contraception in breastfeeding women.

  • There is a tiny increased risk of breast cancer with all progesterone only contraception. Please inform your doctor if you have a family history of breast cancer and you think you are at high risk. The risk returns to normal risk after stopping the contraception.
