The Mirena IUS

Your Guide to the Mirena Intrauterine System

Understanding the Mirena Intrauterine System (Mirena IUS)

The Mirena® IUS (intrauterine system) is a small, T-shaped device placed inside the womb (uterus) that slowly releases a hormone called levonorgestrel. it is a hormone-bearing coil that provides long-term protection against pregnancy and can also be used to treat heavy menstrual bleeding and endometrial protection in women on oestrogen replacement therapy.


How does it work?

The Mirena® works mainly by:

  • Thickening cervical mucus, making it harder for sperm to reach the egg
  • Thinning the lining of the womb, making it less suitable for implantation
  • In some cases, stopping ovulation (release of eggs)

It starts working immediately if inserted during the first 7 days of your menstrual cycle.


What are the benefits?

  • Highly effective contraception (over 99% effective)
  • Long-lasting – works for up to 5 to 8 years, depending on usage
  • Can make periods lighter or stop altogether
  • Reversible – fertility returns quickly after removal
  • May help relieve heavy periods, painful periods, or endometriosis
  • Can be used as part of HRT (hormone replacement therapy)


Who can use it?

The Mirena® is suitable for many women, including:

  • Those who want long-term contraception
  • Women who have heavy or painful periods
  • Women who are breastfeeding
  • Women who cannot take oestrogen
  • Women needing endometrial protection during HRT

Your healthcare provider will check if it’s suitable for you based on your medical history.


What to expect during insertion?

  • Insertion is done by a trained clinician during a clinic visit.
  • It usually takes only a few minutes.
  • You may feel some discomfort or cramping – a painkiller beforehand may help.
  • You can usually go home shortly after the procedure.


After the insertion

  • Some cramping or light bleeding is normal for a few days.
  • Your periods may become irregular or stop entirely over time.
  • You will need a follow-up check (usually after 4–6 weeks).
  • Check for the threads regularly – your clinician will show you how.


Are there any risks or side effects?

Most women tolerate the Mirena® well, but possible side effects include:

  • Irregular bleeding or spotting (common in the first 3–6 months)
  • Cramping or pelvic discomfort after insertion
  • Headache, breast tenderness, mood changes (usually mild and temporary)
  • Small risk of infection (especially within the first 20 days)
  • Very rare risk of expulsion (falling out) or perforation (injury to the womb)


When to seek medical advice?

Contact your doctor if you:

  • Can’t feel the threads or think the device may have moved
  • Experience persistent pain or heavy bleeding
  • Have unusual vaginal discharge or signs of infection
  • Miss a period and are concerned about pregnancy


Removal and replacement

  • The Mirena® can be removed at any time by a trained professional.
  • Fertility returns quickly after removal.
  • If you wish to continue using Mirena®, it can be replaced during the same visit.


Important to know

  • Mirena® does not protect against sexually transmitted infections (STIs) – use condoms for protection.
  • Keep track of your menstrual changes and attend all follow-up appointments.
