Long-Acting Reversible Contraception


Implanon, also known as the contraceptive implant, is a small, flexible rod about the size of a matchstick that is inserted under the skin of the upper arm, providing 99.8% effective birth control for up to three years. It releases a progestin hormone called etonogestrel, which prevents pregnancy by inhibiting ovulation, thickening the cervical mucus, and thinning the lining of the uterus.


Implanon is placed under the skin of the upper arm during a simple and quick procedure. A healthcare provider numbs the area with local anaesthetic, inserts the implant, and applies a small bandage. The procedure is generally well-tolerated and does not require stitches.

Once inserted, Implanon steadily releases the hormone into the bloodstream, providing continuous contraception without the need for daily administration or user-dependent actions.


Implanon offers several benefits in addition to its highly effective contraception. It can help regulate menstrual cycles and reduce menstrual cramps and hormonal acne.

While side effects vary, some women may experience changes in menstrual bleeding patterns, such as irregular or unpredictable bleeding. Others may have lighter or heavier periods or experience no bleeding at all. Additionally, common side effects may include headaches, breast tenderness, and mood changes.
