What is the Levonorgestrel IUD?
The levonorgestrel IUD (intrauterine device) is one of the most effective forms of birth control with an efficacy rate of 99% in preventing pregnancy for up to five years. It is now the most commonly used form of contraception in Australia. It works by a low dose progestin released into the uterus, inhibiting sperm movement so it is more difficult to reach and fertilise the egg. It is also used to treat heavy and painful periods, reducing a period to spotting for some women and ceasing periods altogether for others.

How is an IUD inserted?
Having an IUD is similar to having a CST (Pap smear) but will take between 15 minutes and half an hour. The IUD is usually scheduled for a time when you are not having your period but bleeding does not mean it cannot be done.
-
- An ultrasound is performed to assess the size and shape of the uterus, as well as the ovaries. This helps in placement of the IUD.
-
- A speculum is inserted into the vagina.
-
- The doctor looks at the cervix and a cotton swab may be used to remove excess mucous, and a cleaning solution is applied to the cervix.
-
- Sometimes an instrument is used to hold the cervix and uterus steady. It may be felt as a sharp pinch and there may be some associated cramping pains afterwards.
-
- The IUD is advanced gently and steadily with it’s inserter until it touches the upper uterus. A cramp may be felt.
-
- The inserter is withdrawn and the strings trimmed.
-
- The cervix is wiped and all instruments removed.
-
- The position of the IUD is confirmed with another ultrasound
After the procedure:
It is important to read through the information booklet given to you which includes symptoms to expect following the IUD insertion. We recommend that you do no drive for at least 15 minutes after the insertion. Very rarely, procedures on the cervix can trigger a simple faint. Provided you have no reactions to Panadol or Nurofen these can also safely be used following the insertion.
Use alternative contraception for seven days, after which the Mirena will then be providing contraception reliably.
Looking after yourself after treatment:
-
- You may have some bloodstained discharge for a couple of days, followed by streaking which may last for a couple of weeks.
-
- Contact your doctor if you have any heavy bleeding, fever or smelly vaginal discharge.
-
- Taking time to look after yourself includes a healthy diet, doing some exercise, getting enough sleep and not smoking. These basic lifestyle changes are the best way to stay healthy and well.
- Dr Elgey will advise you when the device will require replacement (typically every 5 years for contraception and up to 7 years for cycle control.)
