Mirena Insertion

What is a Mirena?

Mirena is a small, flexible intrauterine system (IUS) that is placed inside the uterus to provide long-term contraception or to manage gynaecological conditions such as heavy periods, endometriosis, or adenomyosis. It works by releasing a hormone called levonorgestrel, which reduces bleeding, prevents pregnancy, and offers relief from menstrual symptoms. Mirena is effective for up to five years and can be removed if no longer needed, making it a convenient and reversible option.

Why might you need Mirena?

Your doctor may recommend Mirena for various reasons, including:

• Contraception: A highly effective and long-lasting method that doesn’t require daily attention.
• Heavy or painful periods: Helps to reduce or stop menstrual bleeding and cramps.
• Endometriosis or adenomyosis: Provides hormonal relief for associated pain and symptoms.
• Menopausal hormone therapy: Protects the uterine lining when combined with oestrogen therapy.
• Non-surgical management: An alternative to more invasive procedures for certain conditions.

Preparing for Mirena insertion

Preparation ensures a smooth procedure. Here’s what to expect:

• Consultation: Your doctor will review your medical history, perform a pelvic exam, and may recommend swabs or an ultrasound.
• Timing: Insertion is often scheduled during or just after your period when the cervix is softer, making the process easier.
• Pain relief: Taking a painkiller like ibuprofen before your appointment can help minimise discomfort.
• Questions: This is your chance to discuss any concerns or ask questions about the procedure.

What happens during the procedure?

Mirena insertion is a quick, outpatient procedure typically taking less than 10 minutes:

• Positioning: You’ll lie on an examination table while a speculum gently opens the vagina.
• Preparation: The cervix is cleaned and stabilised for the procedure.
• Device placement: A thin tube containing the Mirena device is passed through the cervix into the uterus. Once in place, the tube is removed, and the device stays securely positioned.
• Thread trimming: The threads are cut to sit just outside the cervix, allowing for easy removal later.

Benefits of Mirena

• Highly effective: Over 99% effective at preventing pregnancy.
• Long-lasting: Provides reliable contraception for up to five years.
• Symptom relief: Reduces or eliminates heavy periods, cramps, and symptoms of endometriosis.
• Convenient: Requires no daily attention, unlike pills or other methods.
• Reversible: Can be removed anytime if you wish to conceive or no longer need it.

Are there any risks?

Mirena is very safe, but potential risks include:

• Cramping or discomfort during or after insertion.
• Spotting or irregular bleeding in the first few months.
• Expulsion of the device (rare, but more likely in the first few weeks).
• Infection in the uterus (rare).
• Uterine perforation (extremely rare).

Your doctor will explain these risks and provide advice on how to minimise them.

Recovering From Mirena insertion

Most women recover quickly and can resume normal activities the same day. Here’s what to expect:

• Mild cramping or spotting: These are common in the first few days and can be managed with pain relief.
• Follow-up: Your doctor may schedule a check-up 4 to 6 weeks after insertion to ensure the device is in place and address any concerns.
• Long-term benefits: Enjoy effective contraception and symptom relief for up to five years. Removal is simple and quick if needed.

Looking ahead: what can you expect?

Mirena is one of the most effective and reliable contraceptive options available, with the added benefit of treating heavy periods and painful menstrual conditions. Many women experience lighter or absent periods and significant relief from gynaecological symptoms within the first few months of use.

Mirena is a first-line treatment for heavy menstrual bleeding and an ideal choice for long-term contraception. It offers a convenient, hormone-based solution with minimal maintenance.

If used for therapeutic purposes, such as treating endometriosis or managing menopausal symptoms, Mirena can provide substantial improvements in quality of life. Your doctor will work with you to ensure it meets your individual needs and goals.
