Jaydess vs Mirena – A Comparison of Two Intrauterine Devices
Jan 20, 2025
Intrauterine devices (IUDs) are becoming increasingly popular as a reliable and long-term contraceptive method. According to a study published in the BMJ Sexual & Reproductive Health, IUDs are highly effective and safe, with a low rate of complications. This has led to a significant rise in their usage worldwide.
Two of the most commonly used IUDs are Jaydess and Mirena. Jaydess is a smaller, three-year hormonal IUD that releases a low dose of levonorgestrel. On the other hand, Mirena is a slightly larger device that can last up to five years and releases a higher dose of the same hormone.
In this article, we will compare Jaydess vs Mirena, highlighting their differences, benefits, and potential side effects to help you make an informed decision about which IUD might be best for you.
Key Takeaways
- Overview: Jaydess and Mirena are hormonal intrauterine devices (IUDs) that release levonorgestrel to prevent pregnancy by thickening cervical mucus, thinning the uterine lining, and sometimes suppressing ovulation.
- Mirena provides up to 5–8 years of contraception, while Jaydess offers protection for up to 3 years.
- Mirena has a higher initial hormone dose of 20 micrograms per day, while Jaydess releases 13.5 micrograms daily, making it a gentler option for those sensitive to hormones.
- Mirena’s larger size suits those with a larger uterus or who have given birth, while Jaydess is smaller, ideal for younger or first-time IUD users.
- Both IUDs may cause irregular bleeding, mood changes, or mild cramping initially, which typically subside over time.

Overview of Jaydess and Mirena
Mirena and Jaydess are hormonal intrauterine devices (IUDs) designed to provide long-term, reliable contraception. Both IUDs work by releasing a small, steady dose of the hormone levonorgestrel, which prevents pregnancy through multiple mechanisms: thickening cervical mucus to block sperm, thinning the uterine lining to make implantation less likely, and sometimes suppressing ovulation.
While they share the same core purpose, Mirena and Jaydess are tailored to meet different needs. Mirena provides protection for up to five years, making it ideal for individuals seeking longer-term contraception. Jaydess, on the other hand, is smaller and lower in hormone dosage, making it a suitable choice for those who prefer a shorter duration of use (up to three years) or for those who may not have previously used an IUD
Duration and Effectiveness
Mirena is approved for up to five years of use, making it an ideal choice for those seeking a longer-term contraceptive solution. Its higher hormone dosage allows for sustained release over a more extended period while maintaining consistent effectiveness.
Jaydess, on the other hand, provides contraception for up to three years, catering to individuals who prefer a shorter-term option or are new to IUDs. Its lower hormone dosage and smaller size are particularly suited to younger users or those with a smaller uterus.
Size and Suitability for Different Patients
Mirena is slightly larger, with dimensions of approximately 32 mm x 32 mm, and is well-suited for those who have previously given birth or who are comfortable with a standard-sized IUD. Its larger size allows it to deliver a higher hormone dose, making it effective for managing not only contraception but also conditions like heavy menstrual bleeding.
Jaydess is smaller, measuring about 28 mm x 30 mm, and is designed to be more comfortable for younger individuals or those with a smaller uterus. Its compact size, combined with a lower hormone dosage, makes it a popular choice for first-time IUD users or individuals who may experience sensitivity to larger devices.
Hormonal Release: Jaydess vs Mirena
Mirena releases an initial dose of 20 micrograms per day of levonorgestrel, which gradually decreases over time. This higher dose provides long-lasting contraception for up to eight years and is effective for managing conditions like heavy menstrual bleeding or endometriosis.
On the other hand, Jaydess releases an initial dose of 13.5 micrograms per day of levonorgestrel, which also tapers off over time. Its lower hormone dose is sufficient for three years of contraception, offering a gentler option for those sensitive to higher hormone levels or new to hormonal IUDs.
Side Effects Comparison
Both Jaydess and Mirena are highly effective contraceptive options, but patients should be aware that side effects can occur, especially during the first few months as the body adjusts to the device. Common Jaydess side effects, as well as those associated with Mirena, may include:
- Irregular bleeding or spotting, particularly in the first 3-6 months
- Lighter periods or, in some cases, no periods at all
- Headaches
- Mood changes, such as irritability or mild depression
- Acne or changes in skin condition
- Breast tenderness
- Abdominal pain or cramping
- Nausea
- The development of benign ovarian cysts
For most users, these side effects diminish over time as the body adapts to the IUD. However, if symptoms persist or worsen, it is important to consult a healthcare provider to ensure the device is the right fit for the individual’s needs.
Choosing Between Jaydess and Mirena
Choosing between Jaydess and Mirena depends on several factors related to your personal preferences, health needs, and lifestyle. Here are some key considerations to help guide your decision:
- Duration of Use: If you prefer a long-term solution, Mirena may be the better option as it is approved for up to eight years. Jaydess, on the other hand, is suitable for up to three years, making it a good choice if you’re looking for a shorter-term commitment.
- Hormone Dose and Side Effects: Mirena releases a higher dose of levonorgestrel (20 micrograms per day initially) compared to Jaydess (13.5 micrograms per day). If you’re sensitive to hormones or concerned about potential side effects, Jaydess might be more suitable due to its lower hormone dosage.
- Size and Comfort: Mirena is slightly larger (32 mm x 32 mm) and may be more appropriate for those who have previously given birth or who are comfortable with a standard-sized IUD. Jaydess is smaller (28 mm x 30 mm) and may be more comfortable for younger individuals or those with a smaller uterus.
- Medical Conditions: Mirena is effective not only for contraception but also for managing heavy menstrual bleeding and conditions like endometriosis due to its higher hormone dosage. If you have these conditions, Mirena might be a more suitable option.
- Personal Preferences: Your comfort and personal preferences play a significant role in this decision. Consider discussing your options with a healthcare provider, who can help you weigh the pros and cons based on your medical history and lifestyle.
Conclusion
Both Jaydess and Mirena offer highly effective and long-lasting contraception, catering to different needs. Jaydess suits individuals seeking a shorter-term, lower-dose option, while Mirena is ideal for those requiring extended protection or additional therapeutic benefits for conditions like heavy menstrual bleeding. Consulting with a healthcare provider ensures a personalized choice, addressing comfort, efficacy, and overall health considerations.
