1. What Jaydess is and what it is used for

Jaydess is used for the prevention of pregnancy (contraception) for up to three years.

Jaydess is a T-shaped intrauterine delivery system (IUS) which after placement inside the womb slowly releases a small amount of the hormone levonorgestrel.

Jaydess works by reducing the monthly growth of the lining of the womb and thickening the cervical mucus. These actions prevent the sperm and egg from coming into contact and so prevent fertilization of an egg by sperm.


2. What you need to know before you use Jaydess

General notes

Before you can begin using Jaydess, your healthcare professional will ask you some questions about your personal health history.

In this leaflet, several situations are described where Jaydess should be removed, or where the reliability of Jaydess may be decreased. In such situations you should either not have intercourse or you should use a condom or another barrier method.

Jaydess, like other hormonal contraceptives, does not protect against HIV infection (AIDS) or any other sexually transmitted disease.

Jaydess is not suitable for use as an emergency contraceptive (postcoital contraceptive).

Do NOT use Jaydess if you:

  • are pregnant (see section “Pregnancy, breast-feeding and fertility”)
  • currently have a pelvic inflammatory disease (PID; infection of the female reproduction organs) or have had this condition multiple times in the past.
  • have conditions associated with increased susceptibility to pelvic infections
  • have an infection in the lower genital tract (an infection in the vagina or the cervix [neck of the womb])
  • have had an infection of the womb after delivery of a child, after an abortion or after miscarriage during the past 3 months
  • currently have cell abnormalities in the cervix
  • have cancer or suspected cancer of the cervix or womb
  • have tumours which are sensitive to progestogen hormones to grow, e.g., breast cancer
  • have unexplained uterine bleeding
  • have an abnormality of the cervix or womb including fibroids that distort the cavity of the womb
  • have an active liver disease or liver tumour
  • are allergic to levonorgestrel or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your healthcare professional before using Jaydess if you

  • have diabetes. There is generally no need to alter your diabetic medication while using Jaydess, but this may need to be checked by your healthcare professional
  • have epilepsy. A fit (seizure) can occur during placement or removal
  • have had an ectopic or extrauterine pregnancy (pregnancy outside the womb) in the past.

In addition, also talk to your healthcare professional if any of the following conditions exist before you use Jaydess or appear for the first time while using Jaydess:

  • migraine, with visual disturbances or other symptoms which may be signs of a transient cerebral ischemia (temporary blockage of the blood supply to the brain)
  • exceptionally severe headache
  • jaundice (a yellowing of the skin, whites of the eyes and/or nails)
  • marked increase in blood pressure
  • severe disease of the arteries such as stroke or heart attack.

The following signs and symptoms could mean that you may have an extrauterine pregnancy and you should see your healthcare professional immediately (see also section “Pregnancy, breast-feeding and fertility”):

  • Your menstrual periods have stopped and then you start having persistent bleeding or pain
  • You have pain in your lower abdomen that is severe or persistent
  • You have normal signs of pregnancy, but you also have bleeding and feel dizzy.
  • You have a positive pregnancy test

Contact your healthcare professional promptly if any of the following occur (see also section 4) and remind them that you have a Jaydess device, especially if they were not the person who inserted it:

  • severe pain (like menstrual cramps) or heavy bleeding after placement or if you have pain/bleeding which continues for more than a few weeks. This may be for example a sign of infection, perforation or that Jaydess is not in the correct position.
  • you no longer feel the threads in your vagina. This may be a sign of expulsion or perforation. You can check by gently putting a finger into your vagina and feeling for the threads at the end of your vagina near the opening of your womb (cervix). Do not pull the threads because you may accidentally pull out Jaydess. Use a barrier contraceptive (such as condoms) until your healthcare professional has checked that the IUS is still in position.
  • you or your partner can feel the lower end of Jaydess. Avoid intercourse until your healthcare professional has checked that the IUS is still in position.
  • your partner feels the removal threads during intercourse.
  • you think you may be pregnant
  • you have persistent abdominal pain, fever, or unusual discharge from the vagina, which may be a sign of infection. Infections must be treated immediately.
  • you feel pain or discomfort during sexual intercourse, which may be for example a sign of infection, ovarian cyst or that Jaydess is not in the correct position.
  • there are sudden changes in your menstrual periods (for example, if you have little or no menstrual bleeding, and then you start having persistent bleeding or pain, or you start bleeding heavily), which may be a sign of Jaydess not being in the correct position or expelled.

Use of sanitary pads is recommended. If tampons or menstrual cups are used, you should change them with care so as not to pull the threads of Jaydess. If you think you may have pulled Jaydess out of place (see list above for possible signs), avoid intercourse or use a barrier contraceptive (such as condoms), and contact your healthcare professional.

Psychiatric disorders

Some women using hormonal contraceptives including Jaydess have reported depression or depressed mood. Depression can be serious and may sometimes lead to suicidal thoughts. If you experience mood changes and depressive symptoms contact your doctor for further medical advice as soon as possible.

Children and adolescents

Jaydess is not indicated for use before the first menstrual bleeding (menarche).

Other medicines and Jaydess

Tell your healthcare professional if you are taking, have recently taken or might take any other medicines.

Pregnancy, breast-feeding and fertility


Jaydess must not be used during pregnancy.

Some women may not have their periods while using Jaydess. Not having a period is not necessarily a sign of pregnancy. If you do not have your period and have other symptoms of pregnancy you should see your healthcare professional for an examination and have a pregnancy test.

If you have not had a period for six weeks and are concerned, then consider having a pregnancy test. If this is negative, there is no need to carry out another test unless you have other signs of pregnancy.

If you become pregnant with Jaydess in place, you should see your healthcare professional immediately to have Jaydess removed. The removal may cause a miscarriage. However, if Jaydess is left in place during pregnancy, not only is the risk of having a miscarriage higher, but also the risk of preterm labour. If Jaydess cannot be removed, talk with your healthcare professional about the benefits and risks of continuing the pregnancy. If the pregnancy is continued, you will be closely monitored during your pregnancy and you should contact your healthcare professional right away if you experience stomach cramps, pain in your stomach or fever.

Jaydess contains a hormone, called levonorgestrel, and there have been isolated reports of effects on the genitalia of female babies if exposed to levonorgestrel intra-uterine devices while in the womb.

If you want to become pregnant you should contact your healthcare professional to have Jaydess removed.

Extrauterine pregnancy

(pregnancy outside the womb)

It is uncommon to become pregnant while using Jaydess. However, if you become pregnant while using Jaydess, the risk that the pregnancy could develop outside the womb (have an extrauterine or ectopic pregnancy) is increased. Women who have already had an extrauterine pregnancy, surgery of the fallopian tubes or a pelvic infection carry a higher risk for this type of pregnancy. An extrauterine pregnancy is a serious condition which calls for immediate medical attention (see section 2, “Warnings and precautions for signs and symptoms”) and may impact future fertility.


You can use Jaydess during breast-feeding. Levonorgestrel (the active ingredient in Jaydess) has been identified in small quantities in the breast milk of breast-feeding women. However, no negative effects have been seen on infant growth and development or the amount or the quality of the breast milk.


Your usual level of fertility will return after Jaydess is removed.

Driving and using machines

Jaydess has no influence on the ability to drive or use machines.


3. How to use Jaydess

Placement of Jaydess

Jaydess can either be placed:

  • within seven days from the start of your menstrual bleed (your monthly period)
  • immediately after a first trimester abortion provided that there are no genital infections
  • after giving birth only after the womb has returned to its normal size, and not earlier than 6 weeks after delivery (see section 4 “Possible side effects – Perforation”).

Examination by your healthcare professional before placement may include:

  • a cervical smear test (Pap smear)
  • examination of the breasts
  • other tests, e.g. for infections, including sexually transmitted diseases, as necessary. Your healthcare professional will also do a gynaecological examination to determine the position and size of the womb.

After a gynaecological examination:

  • An instrument called a speculum is placed into the vagina, and the cervix may be cleansed with an antiseptic solution. Jaydess is then placed into the womb using a thin, flexible plastic tube (the placement tube). Local anaesthesia may be applied to the cervix prior to placement.
  • Some women feel dizzy or faint during placement or after Jaydess is placed or removed.
  • You may experience some pain and bleeding during or just after placement.

After placement of Jaydess you should receive a patient reminder card from your doctor for follow-up examinations. Bring this with you to every scheduled appointment.

Follow-up examination and when to seek advice from your doctor:
You should have your Jaydess checked 4-6 weeks after placement, and thereafter regularly, at least once a year. Your doctor may determine how often and what kinds of check-ups are required in your particular case. Bring the patient reminder card you have received from your doctor to every scheduled appointment. In addition, you should contact your doctor if any of the symptoms described in section 2 “Warnings and precautions” occur.

Removal of Jaydess

Jaydess should be removed no later than the end of the third year of use.

Jaydess can be easily removed at any time by your healthcare professional, after which pregnancy is possible. Some women feel dizzy or faint during or after Jaydess is removed. You may experience some pain and bleeding during removal of Jaydess.

If pregnancy is not desired, Jaydess should not be removed after the seventh day of the menstrual cycle (monthly period) unless you use other methods of contraception (e.g. condoms) for at least 7 days before the IUS removal.

If you have irregular periods (menses) or no periods, you should use a barrier method of contraception for 7 days before removal.

A new Jaydess can also be placed immediately after removal, in which case no additional protection is needed.


4. Possible side effects

Description of selected possible side effects:

Irregular or infrequent bleeding

Jaydess is likely to affect your menstrual cycle. It can change your menstrual periods so that you have spotting (a small amount of bleeding), shorter or longer periods, lighter or heavier bleeding, or no bleeding at all.

You may have bleeding and spotting between menstrual periods, especially during the first 3 to 6 months. Sometimes the bleeding is heavier than usual at first.

Overall, you are likely to have a gradual reduction in the amount and number of days of bleeding each month. Some women eventually find that periods stop altogether.

The monthly thickening of the lining of the womb may not happen due to the effect of the hormone and therefore there is nothing to come or shed away as a menstrual period. It does not necessarily mean that you have reached menopause or are pregnant. Your own hormone levels usually remain normal.

When the system is removed, your period should soon return to normal.

Pelvic Infection

The Jaydess inserter and Jaydess itself are sterile. Despite this, there is an increased risk of pelvic infection (infections in the lining of the womb or the fallopian tubes) at the time of placement and during the first 3 weeks after the placement.

Pelvic infections in IUS users are often related to the presence of sexually transmitted diseases. The risk of infection is increased if you or your partner have multiple sexual partners or if you have had pelvic inflammatory disease (PID) before.

Pelvic infections must be treated promptly.

Pelvic infections such as PID may have serious consequences and it may impair fertility and increase the risk of a future extrauterine pregnancy (pregnancy outside the womb). In extremely rare cases severe infection or sepsis (very severe infection, which may be fatal) can occur shortly after insertion.

Jaydess must be removed if you experience recurring PID or if an infection is severe or does not respond to treatment.


The muscular contractions of the womb during menstruation may sometimes push the IUS out of place or expel it. This is more likely to occur if you are overweight at the time of IUS insertion or have a history of heavy periods. If the IUS is out of place, it may not work as intended and therefore, the risk of pregnancy is increased. If the IUS is expelled, you are not protected against pregnancy anymore.

Possible symptoms of an expulsion are pain and abnormal bleeding but Jaydess may also come out without you noticing. As Jaydess decreases menstrual flow, increase of menstrual flow may be indicative of an expulsion.

It is recommended that you check for the threads with your finger, for example while having a shower. See also section 2 “Warnings and precautions” for how to check if Jaydess is in place. If you have signs indicative of an expulsion or you cannot feel the threads, you should use another contraceptive (such as condoms), and consult your healthcare professional.


Penetration or perforation of the wall of the womb may occur during placement of Jaydess, although the perforation may not be detected until sometime later. If Jaydess becomes lodged outside the cavity of the womb, it is not effective at preventing pregnancy and it must be removed as soon as possible. You may need surgery to have Jaydess removed. The risk of perforation is increased in breast-feeding women and in women who have insertion up to 36 weeks after birth, and may be increased in women with the uterus fixed and leaning backwards (fixed retroverted uterus). If you suspect you may have experienced a perforation, seek prompt advice from a healthcare provider and remind them that you have Jaydess inserted, especially if they were not the person who inserted it.

Ovarian cyst

Since the contraceptive effect of Jaydess is mainly due to its local effect in the womb, ovulation (release of the egg) usually continues while using Jaydess. Sometimes an ovarian cyst may develop. In most cases there are no symptoms.

An ovarian cyst may require medical attention, or more rarely surgery, but it usually disappears on its own.

Reporting of side effects

If you get any side effects, talk to your doctor or nurse. This includes any possible side effects not listed in this leaflet. You can also report side effects directly (see details below). By reporting side effects you can help provide more information on the safety of this medicine.
