- Implanon is a progestin hormone-containing rod that is inserted under the skin of a woman's arm. It works primarily by preventing ovulation, but also works by thickening the cervical mucus and altering the lining of the uterus. Implanon provides contraception for at least 3 years and can be removed at any time.
- Provides long-term protection against pregnancy.
- Highly effective and easy to use (no daily pill to remember).
- No interruption of sex.
- Contains no estrogen (estrogen is sometimes associated with higher risk of blood clots).
- May experience unscheduled and irregular bleeding, especially during early months of use.
- Needs to be inserted by a health care provider.
- Offers no protection against STIs.
- Failure rate is .05%
Contact the Student Health Center or your health care provider.
- Implanon should not be used by women experiencing unexplained abnormal vaginal bleeding, or by breastfeeding women less than 6 weeks after birth. Additionally, women with active hepatitis, current breast cancer, or a current blood clot should not use this method of contraception. After Implanon removal, most users return to fertility within 6 weeks.
