The contraceptive implant (Nexplanon) is a small flexible plastic rod that's placed under the skin in your upper arm by a doctor or nurse.
It releases the hormone progestogen into your bloodstream to prevent pregnancy and lasts for 3 years.​
At a glance: the implant
-
The implant is more than 99% effective.
-
Once the implant is in place, you don't have to think about it again for 3 years.
-
It can be useful for women who can't use contraception that contains oestrogen.
-
It's very useful for women who find it difficult to remember to take a pill at the same time every day.
-
The implant can be taken out if you have side effects.
-
You can have it removed at any time, and your natural fertility will return very quickly.
-
When it's first put in, you may feel some bruising, tenderness or swelling around the implant.
-
Your periods may become irregular, lighter, heavier or longer.
-
A common side effect is that your periods stop (amenorrhoea). It's not harmful, but you may want to consider this before deciding to have an implant.
-
Some medicines can make the implant less effective.
-
It doesn't protect against sexually transmitted infections (STIs), so you may need to use condoms as well.
How it works
The implant steadily releases the hormone progestogen into your bloodstream, which prevents the release of an egg each month (ovulation).
​
It also thickens the cervical mucus, which makes it more difficult for sperm to move through the cervix, and thins the lining of the womb so a fertilised egg is less likely to implant itself.
​
When it starts to work
​
You can have the implant put in at any time during your menstrual cycle, as long as you're not pregnant.
If the implant is fitted during the first 5 days of your menstrual cycle, you'll be immediately protected against becoming pregnant.
​
If it's fitted on any other day of your menstrual cycle, you'll need to use additional contraception (such as condoms) for 7 days.
​
After giving birth
​
You can have the implant fitted any time after you've given birth.
​
If it's fitted before day 21 after the birth, you'll be immediately protected against becoming pregnant.
If it's fitted on or after day 21, you'll need to use additional contraception (such as condoms) for the next 7 days.
​
It's safe to use the implant while you're breastfeeding.
​
After a miscarriage or abortion
​
The implant can be fitted immediately after a miscarriage or an abortion and you'll be protected against pregnancy straight away.
How is a contraceptive implant fitted or removed?
A local anaesthetic is used to numb the area on the inside of your upper arm.
​
The implant is then inserted under your skin – it only takes a few minutes to put in and feels like having an injection. You won’t need any stitches after your implant has been fitted.
​
Nexplanon works for 3 years before it needs to be replaced. You can use this method until you reach the menopause, when a woman's monthly periods stop naturally.
​
The implant can be removed at any time by a specially trained doctor or nurse. It only takes a few minutes to remove, and a local anaesthetic will be used. The doctor or nurse will make a tiny cut in your skin to gently pull the implant out.
​
As soon as the implant has been removed, you'll no longer be protected against pregnancy.

​
Will other medicines affect the implant?
​
Some medicines can make the implant less effective, such as:
​
-
medicines for HIV, epilepsy and tuberculosis
-
complementary remedies, such as St John's Wort
-
some antibiotics, such as rifabutin or rifampicin
​
If you're taking any of these medicines, you'll need additional contraception (such as condoms), or you may wish to use a different method of contraception that isn't affected by your medicine.
​
Always tell your doctor that you're using an implant if you're prescribed any medicine. You can also ask them whether the medicine you're taking will affect the implant.
​

You should also see a GP or healthcare professional at any time if:
​
-
you can't feel the implant
-
the implant feels like it's changed shape
-
you notice any changes to the skin or feel any pain at the site of the implant
