How effective is it?
The implant is extremely effective – less than 1 woman in 1000 using Nexplanon will get pregnant over its 3 year duration of use.

How does it work?
The main way Nexplanon works is to stop the ovaries from realeasing an egg each month.

When should I have the Nexplanon inserted?
It is usual to have an Nexplanon inserted within the first 5 days of your period. This means you will be immediately protected from pregnancy.

How is a Nexplanon inserted?

They will have injected some local anaesthetic into the skin the numb the area so that inserting the Nexplanon will not hurt. You will not have any stitches and it will only take a few minutes. The area may be a bit sore and bruised but it will have a dressing on it to help keep it clean and dry. Try not to knock it. After a few days you can remove the dressing and once healed  you really should not be aware that it is there. You should be able to do all the things you would normally do with your arm. Usually you cannot see the Nexplanon but you are normally able to feel it.

If you use any of these drugs it would better to use a different contraception and you should discuss this with your doctor or nurse. Always tell your doctor, nurse or dentist that you are using Nexplanon if they want to prescribe you any medicine.
  • Diarrhoea and vomiting does not affect Nexplanon.

They will apply some paper stitches and a dressing to keep the area dry and clean. The dressing can be removed after a few days and the stitches can usually be removed after a week. The area may be a bit sore and bruised for a few days. If an Nexplanon is very difficult to feel under the skin it may not be so easy to remove. The doctor or nurse may refer you to a specialist centre to have it removed with the help of an ultrasound scan.
