The Contraceptive implant

How effective is it?

The Contraceptive Implant is over 99% effective.
Less than one woman in 1,000 who use the Contraceptive Implant will get pregnant over three years.

How does it work?

A small flexible rod is put under the skin of the upper arm. It releases the hormone progestogen. It stops ovulation and thickens cervical mucus to prevent sperm from reaching an egg, and thins the lining of the uterus to prevent a fertilised egg implanting.


What are the advantages?

The Contraceptive Implant works for three years but can be taken out sooner.
You don’t have to think about contraception for as long as the implant is in place.
When the implant is removed your fertility will return to normal.

What are the disadvantages?

Periods may stop altogether, be irregular, or become longer than usual.
Acne may occur.
Some women report having mood changes and breast tenderness.
It requires a small procedure to fit and remove it.


Anything else I should know?

The Contraceptive Implant is put in using a local anaesthetic and no stitches are needed. This procedure may cause tenderness, bruising and some swelling.
You may feel the implant with your fingers, but it cannot be seen.
Some medicines may stop the implant from working.
