Background Information

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.

Advantages

• 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)

Disadvantages

• 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

Efficacy

Failure rate is .05%

Additional Information

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.
