Levonorgestrel

Mirena

Mirena is a brand-name medication intrauterine device or system (IUS) that medical professionals prescribe to prevent pregnancy. This device also helps in managing heavy menstrual bleeding. The device contains the active drug levonorgestrel, and this device is placed inside the uterine by a medical expert. It is a small T-shaped device that releases a small amount of hormone. It is effective for up to 8 years to prevent pregnancy and 5 years to manage heavy menstrual bleeding. Women are advised not to share their IUDs with other women as it can cause severe infections. 

Product Overview

Mirena IUS (Intrauterine System) is a long-acting, reversible contraceptive device that provides up to five years of protection. It contains 52 mg of levonorgestrel, a hormone that thickens cervical mucus, preventing sperm from attaching to the egg, thins the uterine lining & may also inhibit ovulation. Mirena is FDA-approved and requires a prescription. It is designed for women seeking effective, low-maintenance birth control.

Mirena is available as a small, T-shaped plastic device that is inserted into the uterus by a healthcare professional. Once in place, it releases levonorgestrel at a controlled rate. It is suitable for women who have had at least one child and is also used to treat heavy menstrual bleeding. 

Common side effects of Mirena are changes in menstrual bleeding patterns, headaches, and breast tenderness. Before using Mirena IUS, discuss your medical history with your healthcare provider to ensure it is the right option for you. If a dose is missed or an overdose is suspected (e.g., if the device moves or is expelled), contact your healthcare provider immediately. Moreover, you can store Mirena in a cool, dry place at room temperature. Keep out of reach of children and dispose of it properly after use.

It is used for the following purposes: 

• Contraception: Mirena IUS or IUD is a highly effective long-term contraceptive option. 
• Menstrual Bleeding: It is also helpful in managing heavy menstrual bleeding.
• Uterine Protection: It minimizes the risk of endometrial hyperplasia (thick uterus lining) during estrogen replacement therapy.
• Emergency Contraception: Mirena can be used as an emergency contraceptive option within five days of unprotected sex.

What Are the Recommended Dosage of Mirena?

The dosage recommendations for Mirena depend on several factors, including the type and severity of your medical condition and the form of medication you take. Generally, medical professionals prescribe a starting dose and gradually adjust the drug doses as needed. It is important to note that the dosage recommendations below are only for the average dose. So, if you have been prescribed a different dose, do not change it without consulting your medical practitioner.  

For Preventing Pregnancy

• This device contains 52 mg of levonorgestrel that is released gradually. 
• After the device is inserted, the hormone starts releasing at a rate of 21 mcg per day (after 24 days). 
• Once the device has completed five years, the rate decreases to 11 mcg per day. 
• After eight years, it reduces to about 7 mcg per day. 
• Mirena IUD is effective for up to eight years.

For Heavy Menstrual Bleeding

• At the initial stages, the release rate of levonorgestrel is 20 to 21 mcg per day.
• After five years, it decreases by 50%.
• If your treatment continues after five years, replace the device after the end of the fifth year. 

Starting Levonorgestrel IUD in Women Not Using Hormonal or Intrauterine Contraception

• Insert the IUD as and when your doctor advises if you are not pregnant.
• Check for ovulation and the possibility of pregnancy before starting the treatment.
• If inserted within 7 days of the menstrual cycle or right after a first-trimester abortion, no backup contraception is needed.
• If you have not inserted the device within the first 7 days of the menstrual cycle, use a barrier method such as condoms, or do not indulge in any vaginal intercourse for 7 days to prevent pregnancy.

Switching to IUD from Oral, Transdermal, or Vaginal Hormonal Contraceptive

• You can insert the device anytime unless your doctor advises otherwise.
• If the device is inserted during the active use of the previous method, continue it for 7 days after IUD insertion.
• If you are using continuous hormonal contraception, discontinue that method 7 days after IUD insertion.

Switching to Levonorgestrel IUD from Injectable Progestin Contraceptive

• Insert the device at any time.
• If it is more than three months since your last injection, use a barrier method such as condoms for seven days after IUD insertion.

Switching to an IUD from a Contraceptive Implant or Another IUD

• Insert the new IUD on the same day the implant is removed.
• You can do this at any time during your menstrual cycle.

Inserting IUD After Abortion or Miscarriage

• First Trimester: Insert the device immediately after your first-trimester abortion or miscarriage.
• Second Trimester: Wait for six weeks or until the uterus returns to its normal size. 
• If you have not had your period yet, check for ovulation before inserting the IUD.
• If you are not pregnant, insert the device anytime.

Inserting IUD After Childbirth

• Wait for at least six weeks after your delivery or until your uterus returns to its normal size. If the uterus does not return to its normal size, wait until it does before inserting the IUD.
• If you have not had your period yet, check for ovulation before inserting the IUD.
• If you are not pregnant, insert the device anytime.

[Note: Remember, these recommendations may vary from person to person. Discuss it with your doctor, and they’ll customize your dosage accordingly.]

How to Use Mirena? 

• Read the medication guide or PIL (patient information leaflet) carefully before you start using this medication. If you have any concerns, ask a medical practitioner.
• This device is inserted through the vagina & placed into the uterus by a medical expert.
• You may feel a little discomfort, pain, or dizziness during the insertion and may also notice minor vaginal bleeding. Consult a medical practitioner if these symptoms persist for more than 30 minutes.
• You can keep the IUD inserted in your uterus for up to 8 years. However, schedule a follow-up visit 4 to 6 weeks after the device is inserted. This step ensures that the device is in the proper position. 
• Ask a medical professional if you require a backup form of birth control for the first 7 days after the IUD insertion to prevent pregnancy until the device starts to work.
• The device may move out of its place or come out by itself. So, after each menstrual period, ensure the device is properly positioned. 
• If you want to continue this method of birth control, remove or replace the used device after 8 years to prevent pregnancy or after five years to manage heavy menstrual bleeding.

[Note: Your doctor will decide the right amount for you based on your condition, following guidelines and studies on the drug. They’ll adjust it as needed over time.]

How Does Mirena Work?

Mirena is a type of intrauterine device that provides long-term birth control. It is a tiny, plastic T-shaped device placed in the uterus by a healthcare provider. Mirena releases a hormone called levonorgestrel, which thickens cervical mucus, preventing sperm from attaching to the egg & thins the uterine lining, making it less suitable for a fertilized egg to implant. Additionally, it may restrict ovulation in some women. Mirena IUS is effective for up to five years to eight years, depending on your choice, and is a popular choice for women seeking reliable, reversible contraception without daily attention.

Are There Any Warnings for Mirena?

Mirena can cause severe side effects in certain patients, or it may not be an ideal treatment option for specific populations due to their medical conditions. So, if you are using Mirena, you should remain cautious as it has several warnings, which are as follows:

• Ectopic Pregnancy: While Mirena is prescribed to prevent pregnancy & is highly effective for this purpose, you can still get pregnant while using a Mirena IUD in rare cases. Such pregnancy can have serious complications, and the most common is ectopic pregnancy. It is a condition in which a fertilized egg attaches to the uterus exterior, like on a fallopian tube. So, if you have had an ectopic pregnancy, pelvic infection, or tubal surgery in the past, consult a doctor. They will closely monitor you during the treatment with the Mirena IUD.
• Blood Clots, Stroke, or Heart Attack: While highly unlikely, using an IUD may result in blood clots, heart attack, or stroke. These side effects were not noticed in Mirena studies but have been observed in patients since the device came on the market. So, before using this device, tell your medical provider if you have any blood clots or a history of stroke or heart attack. These professionals can decide whether Mirena is safe for use or not.
• Pelvic or Genital Infections: Mirena IUS can increase the risk of pelvic or genital infections. Your doctor will not recommend using this device if you have the following:
  • A pelvic inflammatory disease or had one in the past.
  • Had a genital infection post-pregnancy in the last three months.
  • An untreated pelvic infection like cervicitis, vaginitis, or vaginosis until it clears up.
  • A weak immune system, misused IV drugs, or having unprotected sex with more than one partner.

If you have or had a history of pelvic/genital infection before starting treatment with Mirena, talk to a healthcare practitioner. They will determine the best birth control method for you.

• Uterine Bleeding: If you have uterine bleeding, using a Mirena IUD may worsen the condition. So, consult with a medical professional and discuss what other forms of birth control option might be better for you.
• Unusual Uterus Shape: If you have fibroids or any condition that makes your uterus an unusual shape, avoid using this device. Such a condition may affect how effectively the IUD works and likely increases the risk of side effects. 
• Uterus or Cervix Cancer: Mirena is not recommended for use in people who have uterus or cervix cancer. Ask your doctor about alternative birth control option that suits your medical needs.
• Breast Cancer or Other Progestogen-Sensitive Cancer: If you have breast cancer or have a history of such conditions, avoid using the Mirena IUD. This device contains levonorgestrel, a synthetic form of progestogen that can increase the risk of breast cancer and other related complications. Talk to a medical professional about this and discuss the alternate birth control options that suit your medical conditions.

What Are the FDA Boxed Warning for Mirena?

Boxed warnings, also called black-boxed warnings, are among the most stringent guidelines issued by the FDA. These warnings alert doctors and patients about the harmful effects of a particular drug, which can be life-threatening if overlooked. Mirena does not have any boxed warnings, meaning it is safe to use. However, its safety is based on the precautions you take. Therefore, if you are taking this drug, follow the instructions provided by your medical practitioner. If you have any concerns or notice any unwanted symptoms, it’s best to consult with an expert.

What Are the Mirena Precautions?

When considering treatment with Mirena, patients should discuss every risk and benefit with their medical practitioner. Here are some of the precautions that you can take before using Mirena for birth control:

• Before using this device, tell your healthcare provider if you are allergic to levonorgestrel, any other progestins (desogestrel and norethindrone), or have other allergies. The product may contain certain inactive components that can cause severe allergic reactions.
• Before using this device, tell your doctor about your or your family’s medical history, especially of: 
  • Depression
  • Diabetes
  • Bleeding disorders
  • High blood pressure
  • Headaches or migraines
  • Heart problems
  • Liver diseases
  • Ectopic pregnancy
  • Stroke
  • Vaginal bleeding
  • Uterus problems
  • HIV
  • Leukemia
  • IV drug abuse
• If you are undergoing surgery or any medical procedure, inform your surgeon or medical professional about the birth control option you use. Moreover, if you are going for an MRI test, tell the expert about the device. They will make the necessary adjustments for your MRI test.
• If you have multiple sexual partners, Mirena IUD may not be an appropriate birth control option for you. Moreover, if you or your partner get a sexually transmitted disease like chlamydia, gonorrhea, or HIV, reach out to a medical professional right away. Ask them whether you should continue using this device or not.
• Do not use this device during your pregnancy. If you become pregnant or think you can be pregnant, tell your doctor immediately.
• Levonorgestrel passes into breast milk, so consult a medical expert to determine whether the device is safe during breastfeeding.
• If you have any liver problem or liver cancer, your doctor will not prescribe you this medication device as contraceptives that contain hormones may lead to liver issues and exacerbate the condition. 

What Are the Contraindications of Mirena? 

It is contraindicated in patients with the following conditions:

• Pregnancy
• Fibroids
• Active or a history of PID (pelvic inflammatory disease)

• Uterine bleeding with unknown cause

What If You Missed a Dose of Mirena?

Since Mirena IUD is a birth control device that is placed in the uterus and works continuously for 5 to 8 years, so there is not a dose to miss like with any birth control pills. However, if your device is removed or expelled, it will not provide the expected contraceptive protection. In such cases, you can reach out to a medical professional. They will guide you with details on what to do in such situations. 

[Note: If you have missed a dose of your medication and are unsure about when to take the next one, immediately consult your doctor or pharmacist.]

What Happens If You Take Too Much of Mirena?

Mirena is an intrauterine device (IUD) or intrauterine system (IUS) that is placed in the uterus. This device releases a small amount of hormone called levonorgestrel. Since it is not something that you can take orally or in doses, there is no concept of taking too many doses. However, if you have questions or concerns about the hormone levels or its side effects, you can discuss them with your healthcare provider. They can provide you with detailed insights and address your specific worries. 

[Note: If you consumed more than the recommended dose, get medical help right away or call the Poison Help line at 1-800-222-1222.]

Frequently Asked Questions

Does Mirena stop periods?

Mirena can significantly reduce or even stop menstrual periods in some women. The device releases levonorgestrel, a hormone that thins the uterine lining, leading to lighter periods or complete cessation of menstruation over time. While some women experience reduced bleeding within a few months, others may continue to have light periods. 

Does Mirena’s IUD cause weight gain?

Weight gain is a possible side effect for some women using the Mirena IUD, but it’s not common. The hormone levonorgestrel, released by Mirena, can affect appetite and fluid retention in a small number of users. However, studies have shown that significant weight gain is not directly associated with Mirena use. If you are concerned about weight changes, it’s best to discuss this with your healthcare provider to explore other factors that might contribute.

Can Mirena cause hair loss?

Although it is not common, hair loss can occur as a side effect of Mirena. The hormonal changes caused by the levonorgestrel released by the device can sometimes lead to hair thinning or shedding in sensitive individuals. If you notice unusual hair loss after getting Mirena, consult your healthcare provider. They can help determine whether the IUD is the cause and discuss potential treatment options or alternative contraceptives if necessary.

Can Mirena help with my PCOS?

Mirena can help manage some symptoms of Polycystic Ovary Syndrome (PCOS), particularly heavy menstrual bleeding. The levonorgestrel released by Mirena thins the uterine lining, reducing menstrual flow and associated pain. However, Mirena does not treat the underlying hormonal imbalances of PCOS, such as irregular ovulation or insulin resistance.

Does Mirena increase the breast size?

Mirena is not typically associated with a significant breast size increase. However, some women may experience breast tenderness or slight swelling due to the hormonal effects of levonorgestrel, especially during the first few months after insertion. These symptoms usually subside as the body adjusts to the IUD. If you notice any unwanted changes in breast size or persistent discomfort, it’s advisable to consult with your medical provider for further evaluation and guidance.
