Contraception - Implanon

Implanon is a contraceptive implant device inserted under the skin of the arm using local anaesthetic to numb the area.  The device is pre-loaded in a disposable applicator for easy insertion.  The device releases a small amount of the hormone etonogestrel continuously into the bloodstream.  The contraceptive effect lasts for up to 3 years.

How does Implanon work?

• It prevents the release of an egg from the ovaries
• It causes changes to the cervical mucous that makes it difficult for sperm to enter the womb

What are the common side effects from Implanon?

The most common side effect is a change in your menstrual bleeding pattern, it may become irregular, absent, infrequent, frequent and in rare cases, heavier.

When during my cycle should I have Implanon inserted?

Implanon implant is usually inserted in the first three days of your cycle, however, it can be inserted at any time during your cycle so long as we’re sure that you’re not pregnant.

What do I need to do on the day of insertion?

We always like to do a pregnancy test on the day of insertion to ensure that you’re not pregnant when we insert the device.  Pregnancy tests can be provided by the Health Hub Hobsons Bay team clinic on the day.

How easy is it to remove the Implanon?

Removal is very similar to insertion – we use a local anesthetic just like the dentist uses to numb the area.  A small incision is made over the insertion area and the Implanon is removed.

How often does Implanon need to be replaced?

Implanon needs to be replaced every 3 years.  You can, however, remove the Implanon any time after insertion.
