A contraceptive implant is a small, flexible rod inserted under the skin of your arm, which continuously releases the hormone etonogestrel to prevent pregnancy. The only available brand in Australia is Implanon NXT. This long-acting reversible contraceptive (LARC) is effective for up to three years.
How Does It Work?
The implant releases etonogestrel, which thickens cervical mucus to block sperm and prevents ovulation. It is highly effective, with less than 1 in 100 users becoming pregnant. However, certain medications can reduce its effectiveness, so inform your doctor of all medications you use.
Insertion and Removal
A trained doctor or nurse inserts the implant using a local anesthetic. Another form of contraception may be needed for the first seven days after insertion. Removal is also done by a trained professional under local anesthetic, and a new implant can be inserted at the same time if desired.
Side Effects
At the Implant Site: Bruising, soreness, and itching can occur. There may be a small scar, and you should consult your doctor if you can’t feel the implant.
Menstrual Changes: Periods may become lighter, stop, or become irregular, more frequent, or longer-lasting. These changes often settle after a few months, but see a doctor if heavy bleeding persists.
Other Side Effects: Potential side effects include headaches, acne, mood changes, weight gain, breast tenderness, and reduced libido.
