Like all medicines, this medicine can cause side effects, although not everybody gets them.
Contact your healthcare professional immediately if you notice any of the following symptoms:
See also section 2 for when to contact your healthcare professional promptly.
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.
Expulsion
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.
Perforation
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.
