Can Mirena Cause High Blood Pressure? Assessing the Effects of Mirena

Share with Friends...

Mirena is a hormonal intrauterine device (IUD) that can provide long-term birth control for up to five years. It is a T-shaped plastic device that is inserted into the uterus by a healthcare provider.

It releases a type of progestin hormone called levonorgestrel, which prevents pregnancy by thickening the cervical mucus, thinning the uterine lining, and sometimes suppressing ovulation.

Mirena is a popular and effective method of contraception, but it may not be suitable for everyone. Some women may wonder if Mirena can cause high blood pressure, which is a risk factor for heart disease and stroke.

What is Mirena

In this blog post, we will explore the possible link between Mirena and high blood pressure, and what you can do to protect your health.

Can Mirena Cause High Blood Pressure?

According to the official website of Mirena, high blood pressure is one of the possible side effects of this IUD.

However, it also states that this side effect is uncommon and that most women do not experience any changes in their blood pressure while using Mirena.

What Research Says?

The research on the association between Mirena and high blood pressure is limited and conflicting. Some studies have found no significant difference in blood pressure levels between women who use Mirena and those who use other forms of contraception or no contraception at all.

Other studies have reported a slight increase in blood pressure in some women who use Mirena, especially those who already have hypertension or other risk factors.

The mechanism by which Mirena may affect blood pressure is not fully understood, but it may be related to the hormonal effects of levonorgestrel on the blood vessels, kidneys, and fluid balance in the body.

It is important to note that the risk of developing high blood pressure from Mirena is very low compared to other factors such as age, weight, family history, smoking, alcohol consumption, stress, and diet.

Moreover, the benefits of using Mirena for birth control and menstrual bleeding usually outweigh the potential risks for most women.

However, if you have a history of high blood pressure or other cardiovascular problems, you should consult your doctor before using Mirena.

How Does Mirena Affect Blood Pressure?

According to the Mayo Clinic, Mirena is generally safe for women who have high blood pressure, as long as it is well controlled and they do not have other risk factors for heart disease.

This is because Mirena contains only progestin and not estrogen, which is the hormone that can increase blood pressure in some women who use combined hormonal birth control methods, such as the pill, the patch, or the ring.

However, this does not mean that Mirena has no effect on blood pressure at all. Some studies have shown that Mirena can slightly increase blood pressure in some women, especially those who are older than 35, overweight, or have a history of hypertension.

The mechanism behind this effect is not fully understood, but it may be related to progestin’s influence on fluid retention, sodium balance, vascular tone, or the renin-angiotensin system.

The increase in blood pressure caused by Mirena is usually mild and does not pose a significant health risk for most women.

However, some women may experience more severe or persistent elevations in blood pressure that may require medical attention or discontinuation of Mirena.

This is more likely to happen if they have other factors that can affect blood pressure, such as:

  • Smoking
  • Diabetes
  • Kidney disease
  • Family history of hypertension
  • Obesity
  • High salt intake
  • Stress
  • Lack of physical activity

How to Prevent and Manage High Blood Pressure While Using Mirena?

Whether you use Mirena or not, there are some lifestyle changes that you can make to prevent and manage high blood pressure.

These include:

  • Eating a healthy diet that is low in salt, saturated fat, and cholesterol, and high in fruits, vegetables, whole grains, lean protein, and low-fat dairy products.
  • Exercising regularly for at least 30 minutes a day, 5 days a week. You can choose any physical activity that you enjoy and that suits your fitness level.
  • Maintaining a healthy weight that is appropriate for your height and body type. You can use a body mass index (BMI) calculator to find out your ideal weight range.
  • Quitting smoking if you are a smoker. Smoking can damage your blood vessels and increase your risk of high blood pressure and other heart diseases.
  • Limiting your alcohol intake to no more than one drink per day for women and two drinks per day for men. Alcohol can raise your blood pressure and interfere with your medications.
  • Managing your stress levels by practicing relaxation techniques such as deep breathing, meditation, yoga, or listening to music. Stress can trigger or worsen high blood pressure by causing your body to release hormones that constrict your blood vessels.
  • Taking your medications as prescribed by your doctor. If you have high blood pressure or other medical conditions that require medication, do not stop or change your dosage without consulting your doctor.
  • Checking your blood pressure regularly at home or at a pharmacy. You can use a digital or manual blood pressure monitor to measure your systolic (top number) and diastolic (bottom number) pressures.


Mirena is a safe and effective birth control method for most women who have high blood pressure or are at risk of developing it.

However, some women may experience a slight increase in blood pressure while using Mirena which may require monitoring and management.

It is important to check your blood pressure regularly and follow a healthy lifestyle while using Mirena.

If you have any concerns or questions about Mirena and high blood pressure, talk to your healthcare provider.
