The Implanon implant is a long lasting, reversible contraceptive method that provides continuous protection from pregnancy for up to 3 years. It becomes effective 24 hours after placement. The Implanon implant consists of matchstick-sized plastic capsules containing a synthetic progesterone hormone. The implants or capsules, are placed by a special hollow needle just under the skin of your upper arm through a very small cut. A local anaesthetic is used for the 10 to 15 minute procedure. Small amounts of the synthetic hormone diffuse from the capsules into the bloodstream to provide continuous protection from pregnancy.
Implanon implants can be removed anytime and the effects leave the body within 24 hours. Under normal conditions, the decision to remove the implants may be because a pregnancy is desired, the 3-year time limit has been reached, or to replace the capsules. Like the initial implantation, removal and replacement is a minor surgical procedure. Implanon takes the timing and thought out of birth control. It is suitable for women who: - are seeking continuous, yet reversible, contraception
- want to space their children
- cannot use methods that contain oestrogen
- do not want to be sterilized or
- desire a method that is convenient and not related to sexual intercourse
The Implanon implant prevents pregnancy several ways. It: - inhibits ovulation so that no egg is released
- thickens and decreases the amount of mucus at the opening of the womb so the sperm cannot get inside and
- thins the lining of the uterus to prevent implantation should fertilization occur
The most common side effect is a change in women's menstrual periods, such as longer periods, bleeding between periods, or skipped periods. Other side effects may occur, such as headache, dizziness, hair growth or loss, change of appetite, weight gain, and acne. Most side effects go away after the first 6 months.
