How effective is the contraceptive implant?
The contraceptive implant is an effective contraceptive method and prevents pregnancy more than 99% of the time. This means that in any given year, less than one in every 100 women will get pregnant while using the implant.
The efficacy of the contraceptive implant can be affected by other medicines, such as the herbal remedy St. John’s Wort and some drugs used to treat epilepsy. Please let your doctor or family planning nurse know if you are taking other medicines before you start using the contraceptive implant.
