Jaydess

The smallest coil with the least hormone – often the first one. Why three years is sometimes exactly the right duration.

Jaydess is the smallest coil on the Austrian market and the one with the least hormone. For many women it is the first coil of all – often for young women, often for women who have not given birth, and often for women who want to come off the pill without immediately committing themselves for the next eight years. This page explains what it can do, where its limits lie and why three years is sometimes exactly the right duration.

What Jaydess is

Jaydess is a T-shaped intrauterine system containing 13.5 milligrams of levonorgestrel. It measures 28 × 30 millimetres, is inserted with an insertion tube 3.8 millimetres in diameter and is licensed for three years. A silver-containing ring at its upper end makes it easy to see on ultrasound and distinguishes it from its larger sister Kyleena, which has the same external dimensions.

Hormone release begins at about 14 micrograms a day and falls over the three years to around 5 micrograms. That is the lowest dose of all the hormonal coils – a quarter of what Mirena contains. Anyone hesitating out of concern about hormones will find here the smallest amount possible in a hormonal coil at all.

Why it is so often the first coil

Two properties make Jaydess the typical coil to start with, and neither has anything to do with caution towards young women, but with practice.

The thin insertion tube. 3.8 millimetres against 4.4 for Mirena sounds like little and is not. The cervical canal of a woman who has not given birth is narrower and less yielding. The diameter of what has to pass through it is therefore the single most important factor in how unpleasant insertion becomes.

The short duration. Three years is a commitment you can take in. Anyone trying a coil for the first time who is not sure whether it suits her does not have to commit to five or eight years. And anyone expecting to want a child in a few years has, with three years, a period that fits her plans for life rather than outlasting them.

Neither argument is a medical restriction. Jaydess is expressly licensed for women who have already given birth as well – it is simply chosen less often there, because Kyleena lasts two years longer at the same size.

The three hormonal coils side by side

Model	Hormone	Initial release	Duration	Tube	Cost per year
Jaydess	13.5 mg	14 µg/day	3 years	3.8 mm	€167
Kyleena	19.5 mg	17.5 µg/day	5 years	3.8 mm	€120
Mirena	52 mg	20 µg/day	up to 8 years	4.4 mm	€94

An honest note about the last column: Jaydess is the most expensive of the three per year. Anyone who knows for certain that she wants contraception for five years does better with Kyleena, at the same size and with the same insertion tube. The extra cost of Jaydess does not buy more comfort but less commitment and the lowest hormone dose. Whether that difference is worth it to you is a question you and not the table answer.

How reliably it prevents pregnancy

The Pearl index of Jaydess is 0.41 in the first year and cumulatively about 0.9 over three years. It is thus marginally less reliable than Kyleena and Mirena – a difference of the order of four against two pregnancies per thousand women per year, which plays no part in everyday life.

It disappears entirely as soon as the comparison is drawn more widely. The combined pill in typical use comes to seven pregnancies per hundred women per year, the condom to thirteen. Jaydess is thus around seventeen times more reliable than the pill as it is actually taken – not as it should be taken.

Method	Perfect use	Typical use
Jaydess	0.4	0.4
Combined pill	0.3	7
Vaginal ring	0.3	7
Condom	2	13

The first row is the only one in which both figures are the same. That is the real point of a coil: there is nothing you could forget, put off or get wrong. All the methods side by side are in the contraception comparison.

How Jaydess works

The levonorgestrel is released directly into the uterus. The level in the blood therefore stays very low – lower with Jaydess than with any other hormonal method. That is precisely the difference from the pill: the same class of substance, but a fraction of the amount and essentially only where it is needed.

Three effects work together:

The cervical mucus becomes thick and practically impenetrable to sperm. That is the main mechanism.
Sperm that do get through lose their motility.
The lining of the uterus stays thin.

Ovulation is preserved with Jaydess practically always – at this low dose it is not suppressed. Your own cycle with its hormonal fluctuations therefore carries on. For many women that is an argument in its favour; anyone who instead wants a break from the cycle, because of pronounced premenstrual symptoms for instance, will not get that with Jaydess.

What happens to the bleeding

Bleeding becomes lighter and shorter, but less markedly so than with the larger models. After a year it stops altogether in about twelve out of a hundred women – with Kyleena it is 23, with Mirena around 20. Anyone turning to a coil above all because the bleeding is a nuisance should know this: among the three hormonal coils, Jaydess is the one that changes the bleeding pattern least.

For many, that is precisely the reason for Jaydess. Not every woman wants the bleeding to disappear; some experience it as feedback from their body and want to keep it, only lighter.

The first months run as they do with all hormonal coils: irregular spotting is the rule in the first three to six months and the commonest reason for early removal. In the licensing studies the number of days with bleeding and spotting in the first month was often in double figures and fell markedly afterwards. Anyone who knows beforehand that this phase comes and passes gets through it considerably more easily.

Jaydess instead of the pill: what changes

The commonest switch in this practice is from the combined pill to a hormonal coil. What changes in the process can be set out clearly.

What goes away: having to think about it every day; the uncertainty after vomiting, diarrhoea or a forgotten tablet; the thrombosis risk of the oestrogen; the recurring prescription. Anyone who has migraine with aura, is using contraception after a thrombosis or smokes over the age of 35 must not take the combined pill anyway – Jaydess is possible in all these cases, because it contains no oestrogen.

What comes back: your own cycle. On the combined pill there is no true ovulation and no true period, but a withdrawal bleed in the break. With Jaydess, ovulation and the fluctuations of the cycle return. Some women experience that as a liberation; others notice premenstrual symptoms that had been suppressed for years. Both occur, and you should have heard about both beforehand.

What stays: what the pill brought with it in the way of side effects does not necessarily disappear. Acne that was better on a pill with an anti-androgenic effect can come back – levonorgestrel is not anti-androgenic. That is one of the few points on which the pill beats the coil.

When Jaydess is out of the question

in pregnancy
with an acute infection in the genital area – treat first, then insert
with unexplained bleeding – investigate first, then insert
with malformations or fibroids that distort the cavity of the uterus
with a history of breast cancer – here the copper coil remains possible
with certain liver diseases

With very heavy bleeding, with endometriosis and as the progestogen component of hormone replacement therapy, Jaydess is the wrong choice – for that Mirena is licensed and effective.

The procedure: two appointments

The first appointment is about the conversation and the preliminary examination: history, bleeding pattern, family planning, contraception used so far and what did not suit about it. Then ultrasound to assess the size and position of the uterus, a wet mount and swabs for organisms. At the end it is settled which model fits and that there is no infection that could be carried upwards during insertion.

At the second appointment it is inserted. The procedure takes a few minutes: preparation of the cervix, introduction of the coil in its tube, release, trimming of the threads, a final ultrasound check. A convenient time is at the end of or shortly after a period.

For women for whom this is the first gynaecological examination of this kind, the rule is: you set the pace. Nothing is done that has not been explained beforehand, and it may be interrupted at any time. Anyone who wants to can bring someone with them.

If it is your first gynaecological appointment

A considerable proportion of the women who come about Jaydess have never seen a gynaecologist, or have been only once or twice. Three things about this are worth knowing.

The first appointment is a conversation. What is examined is what has been discussed and understood – no more. Anyone who at first only wants to talk can do so; a contraception consultation is possible without any examination at all. Before a coil is inserted, however, the examination cannot be dispensed with, because the size and position of the uterus have to be known and an infection has to be ruled out.

The point in the cycle. For the consultation it plays no part; for swabs and for insertion it does. Say what it is about when you make the appointment, and it will be arranged accordingly.

What you should bring: your e-card and photo ID, a list of your medicines, results of earlier examinations if there are any, and the date of your last period. If you are unsure how regular your cycle is, a look at the ovulation calculator beforehand helps.

Jaydess and planning your life

Contraception is rarely a decision for ever, but one for the next stage of life. Three years fit surprisingly well with the stages in which women between twenty and thirty actually live: a degree, a first job, a move, a relationship.

For a semester abroad or a longer journey the coil is the most straightforward method of all: no prescription, no time difference, no need to restock, no question of whether a particular preparation is available in the destination country. It works the same everywhere. Anyone travelling in a region where gynaecological care would be hard to reach should, however, get the check four to six weeks after insertion out of the way before departure.

And if plans change: a coil can be removed early at any time. That takes seconds, hurts considerably less than insertion, and fertility returns immediately. Unlike sterilisation, none of these decisions is final.

What insertion feels like

Unpleasant, and that belongs said honestly. Expect a short, strong cramping pain at the moment when the tube passes the cervix, and after that a dragging sensation like strong period pain which eases over some hours. A painkiller an hour beforehand makes sense and is discussed.

In women who have not given birth it is on average more unpleasant than in women who have – the canal is narrower. That is exactly why the thin insertion tube of Jaydess is the most important argument there. Circulatory reactions with dizziness or nausea occur; they are harmless, pass after minutes, and you may stay lying down as long as you need.

Checks, everyday life and risks

A check takes place four to six weeks after insertion, and yearly after that. Ultrasound shows whether the coil is in the right place; expulsion or displacement occurs in two to five out of a hundred women, most likely in the first months and during a period. In young women who have not given birth it is somewhat commoner.

Sport, sauna and swimming are possible without restriction, and so are tampons. With a menstrual cup, release the suction deliberately before removing it. In the first week after insertion, baths, swimming pools and tampons are advised against.

More serious events are rare. Perforation of the wall of the uterus is of the order of one in a thousand. An ascending infection is somewhat more likely in the first three weeks and not afterwards – the cause is an infection already present, against which the consultation appointment with its swabs protects. Fever, increasing lower abdominal pain or foul-smelling discharge during this time belong investigated the same day. Cysts on the ovary occur somewhat more often, are mostly harmless and disappear by themselves.

Costs

The insertion appointment with Jaydess costs €500 at this private practice. That includes the examination, the ultrasound, a pregnancy test, the wet mount, the medical preparation, the insertion and the coil itself. The preceding contraception consultation with swabs is charged at €250.

Calculated over three years that is around €167 a year, just under €14 a month. You submit the invoice to your health insurance fund, which reimburses 80 per cent of the corresponding public tariff – not 80 per cent of the fee. Contraceptives themselves are not covered by public insurance in Austria. All the amounts are on the page fees. How this works if you are insured outside Austria is set out under health insurance and reimbursement.

After three years

Once the licensed duration has expired, Jaydess has to be changed. The change and the new insertion take place in one appointment. Many women then choose Kyleena: once the first coil has been well tolerated, there is little to be said against the longer duration at an identical size.

If you want to conceive, fertility returns immediately after removal; there is no delay of the kind that follows the three-monthly injection. Folic acid should be started four weeks before the planned conception – the ovulation calculator helps with the timing, and the screening planner shows what else belongs checked before a pregnancy.

What happens next

Whether Jaydess or one of the larger models fits is decided in conversation – by your bleeding pattern, your history and by how far you want to commit yourself. Arranging an appointment, or compare beforehand: coil comparison, Kyleena and the hormonal coil in overview.

Contents of the pack and other information

1. What Jaydess is and what it is used for

Jaydess is used to prevent pregnancy (contraception) for a period of up to three years. Jaydess is a T-shaped intrauterine delivery system (IUS) which, after insertion into the uterus, slowly releases a small amount of the hormone levonorgestrel.

Jaydess works by reducing the monthly growth of the lining of the uterus and thickening the cervical mucus. This prevents sperm and egg cells from coming into contact with one another, which prevents fertilisation of the egg by the sperm.

2. What you need to know before you use Jaydess

General information

Before you can use Jaydess, your doctor will ask you some questions about your personal medical history.

This leaflet describes various situations in which Jaydess should be removed or in which the reliability of Jaydess may be reduced. In such situations you should either not have sexual intercourse or use a condom or another barrier method.

Like other hormonal contraceptives, Jaydess does not protect against HIV infection (AIDS) or other sexually transmitted diseases.

Jaydess is not suitable for emergency contraception (as a post-coital contraceptive).

Jaydess must NOT be used

if you are pregnant (see the section “Pregnancy, breastfeeding and fertility”).
if you currently have pelvic inflammatory disease (PID; an infection of the female reproductive organs) or have had this condition repeatedly in the past.
if you have an illness associated with an increased susceptibility to pelvic infections.
if you have an infection of the lower genital tract (an infection of the vagina or the cervix).
if you have had an infection of the uterus after the birth of a child, a termination or a miscarriage in the last 3 months.
if you currently have cell changes of the cervix.
if you have cancer of the cervix or of the uterus, or such cancer is suspected in you.
if you have a tumour whose growth is sensitive to progestogen, for example breast cancer.
if you have unexplained bleeding from the uterus.
if you have a malformation of the cervix or of the uterus, including fibroids, which distorts the cavity of the uterus.
if you have acute liver disease or a liver tumour.
if you are allergic to levonorgestrel or to any of the other ingredients of this medicine (see section 6).

Warnings and precautions

Talk to your doctor if you

have diabetes. It is generally not necessary to change your diabetes medication while using Jaydess, but this may have to be reviewed by your doctor.
suffer from epilepsy. A seizure may occur during insertion or removal.
have previously had an ectopic or extrauterine pregnancy (a pregnancy outside the uterus).

Also talk to your doctor if one of the following conditions is present before using Jaydess or occurs for the first time while using Jaydess:

migraine with visual disturbance or other symptoms suggesting transient cerebral ischaemia (a temporary interruption of the blood supply to the brain)
exceptionally severe headache
jaundice (yellowing of the skin, the whites of the eyes and/or the nails)
a marked rise in blood pressure
severe vascular disease such as stroke or heart attack

The following signs and symptoms may indicate an extrauterine pregnancy (a pregnancy outside the uterus), which is why you should see your doctor immediately (see also the section “Pregnancy, breastfeeding and fertility”):

Your periods have stopped and you have persistent bleeding or pain.
You have severe or persistent lower abdominal pain.
You have the normal signs of pregnancy but also have bleeding and feel dizzy.
A pregnancy test you have carried out is positive.

Contact your doctor immediately if you experience the following (see section 4), and remind your doctor that you have a Jaydess in place, particularly if they are not the person who inserted it:

severe pain (like period cramps) or heavy bleeding after insertion, or if you have pain or bleeding lasting longer than a few weeks. This may be a sign of an infection or a perforation, for example, or an indication that Jaydess is not in the correct position.
if you can no longer feel the threads in your vagina. This may indicate expulsion or perforation. Carefully introduce a finger into your vagina and feel for the threads at the end of your vagina near the opening of the uterus (the cervix). Do not pull on the threads, as you could pull Jaydess out by accident. Avoid sexual intercourse or use barrier methods (such as a condom) until your doctor has checked whether the IUS is still in the correct position.
if you or your partner can feel the lower end of Jaydess. Avoid sexual intercourse until your doctor has checked that the IUS is correctly in place.
if your partner feels the removal threads during sexual intercourse.
if you think you are pregnant.
if you have persistent abdominal pain, fever or unusual discharge from the vagina; this may be a sign of an infection. Infections have to be treated immediately.
if you have pain or discomfort during sexual intercourse; this may be a sign of an infection or an ovarian cyst, for example, or an indication that Jaydess is not in the correct position.
if sudden changes occur in your periods (for example if you have little or no bleeding and begin to have persistent bleeding or pain, or begin to bleed heavily); this may indicate, for example, that Jaydess is not in the correct position or has been expelled.

The use of sanitary towels is recommended. If you use tampons, you should change them carefully and not pull on the threads of Jaydess.

Psychiatric disorders

Some women using hormonal contraceptives such as Jaydess report depression or depressed mood. Depression can be serious and may occasionally lead to suicidal thoughts. If you experience mood changes and depressive symptoms, seek medical advice from your doctor as soon as possible.

Children and adolescents

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

Other medicines and Jaydess

Tell your doctor if you are taking, have recently taken or intend to take any other medicines.

Pregnancy, breastfeeding and fertility

Pregnancy

Jaydess must not be used during pregnancy.

In some women periods may stop while using Jaydess. An absent period is not necessarily a sign of pregnancy. If you do not have your period and have other signs of pregnancy, you should see your doctor for examination and carry out a pregnancy test.

If you have not had a period for six weeks and are worried, consider a pregnancy test. If it is negative, no further test needs to be carried out unless you have other signs of pregnancy.

If you become pregnant with Jaydess in place, contact your doctor immediately so that Jaydess can be removed. There is a risk of spontaneous miscarriage if Jaydess is removed during pregnancy.

If you leave Jaydess in place during pregnancy, the risk of miscarriage, infection or premature labour is increased. Talk to your doctor about the risks of continuing the pregnancy.

If you want to become pregnant, you should contact your doctor so that Jaydess can be removed.

Extrauterine pregnancy

(pregnancy outside the uterus)

It is unusual to become pregnant while using Jaydess. However, if you do become pregnant while using Jaydess, the risk of a pregnancy outside the uterus (an extrauterine or ectopic pregnancy) is increased. Women who have already had an extrauterine pregnancy, an operation on the fallopian tubes or a pelvic infection are at greater risk of such a pregnancy. An extrauterine pregnancy is a serious condition and must be treated medically without delay (see section 2, “Warnings and precautions, signs and symptoms”) and can lead to infertility.

Breastfeeding

You can use Jaydess while breastfeeding. Levonorgestrel (the active substance in Jaydess) has been detected in small amounts in the breast milk of breastfeeding women.

However, no adverse effects on the growth and development of the infant or on the amount or quality of the breast milk have been observed.

Fertility

After Jaydess is removed, your fertility returns to its normal level.

Driving and using machines

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

3. How to use Jaydess. Insertion of Jaydess

Jaydess can be inserted either:

within seven days of the start of your period,
immediately after a termination of pregnancy in the first trimester (the first three months of a pregnancy), provided there is no genital infection (an infection of the reproductive organs),
after a birth, but only once the uterus has returned to its normal size, and not earlier than 6 weeks after delivery (see section 4, “Possible side effects – perforation”).

The examination by your doctor before insertion may include:

a smear from the cervix (Pap test),
an examination of the breasts,
other tests as required, for example for infections including sexually transmitted diseases. Your doctor will also carry out a gynaecological examination in order to determine the position and size of your uterus.

After a gynaecological examination the following happens:

An instrument called a speculum is introduced into the vagina and the cervix may be cleaned with an antiseptic solution. Jaydess is then introduced into the uterus through a thin, flexible plastic tube (the inserter). Before insertion the cervix may be anaesthetised locally.
Some women feel dizzy or weak during or after the insertion, or during the removal, of Jaydess. You may have pain or bleeding during or immediately after insertion.
During or shortly after insertion you may experience slight pain and bleeding.

Follow-up and when you should ask your doctor for advice:

You should have your Jaydess checked 4 to 6 weeks after insertion and regularly thereafter, but at least once a year. Your doctor will decide how often and which follow-up examinations are necessary in your particular case. In addition you should see your doctor if any of the symptoms named in section 2, “Warnings and precautions”, occurs.

Removal of Jaydess

Jaydess should be removed at the latest at the end of the third year of use. Jaydess can be removed easily by your doctor at any time; pregnancy is possible afterwards. Some women feel dizzy or weak during or after Jaydess is removed. You may have pain and bleeding when Jaydess is removed.

If pregnancy is not desired, Jaydess should not be removed after the seventh day of the menstrual cycle unless you use other contraceptives (for example condoms) for at least seven days before Jaydess is removed.

If your periods are irregular or absent, you should use a barrier method for at least seven days before removal.

A new Jaydess can also be inserted immediately after removal. In that case no additional protection is necessary.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. What follows is a list of possible side effects ordered by frequency:

Contact your doctor without delay if you notice any of the following symptoms:

Uncommon side effects: affects 1 to 10 in 1,000 people

excessive body hair
perforation of the uterus (see the section on perforation below)

Description of selected side effects:

Irregular or infrequent bleeding

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

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

Overall it is likely that the amount of bleeding and the number of days of bleeding will gradually decrease month by month. In some women the periods eventually stop altogether.

Because of the action of the hormone, the monthly thickening of the lining of the uterus may not occur, which is why there is nothing that could be shed as a period. This does not necessarily mean that you have reached the menopause or are pregnant. Your own hormone levels usually remain normal.

After the system is removed, your periods should soon return to normal. Pelvic infection

The Jaydess inserter and Jaydess itself are sterile. Nevertheless the risk of a pelvic infection (infections of the lining of the uterus or of the fallopian tubes) is increased at the time of insertion and in the first 3 to 4 weeks afterwards.

In users of an IUS, pelvic infections are often connected with existing sexually transmitted diseases. The risk of infection is increased if you or your partner have several sexual partners or if you have previously had pelvic inflammatory disease (PID).

Pelvic infections must be treated without delay.

Pelvic inflammation such as PID can have serious consequences and impair fertility as well as increasing the risk of a future extrauterine pregnancy (a pregnancy outside the uterus). In extremely rare cases a serious infection or sepsis (a very serious general infection which can be fatal) can occur shortly after insertion. With recurrent PID, or with a severe infection or one that does not respond to treatment, Jaydess must be removed.

Expulsion

The muscular contractions of the uterus during a period can sometimes cause the IUS to move or be expelled. It is rare but possible for Jaydess to slip out during your period without your noticing. It is also possible for Jaydess to be partly expelled from the uterus, that is, for it to have moved but not been expelled completely (you and your partner may notice this during sexual intercourse). If Jaydess has been expelled completely or partly, you are not protected against pregnancy.

Perforation

Perforation of or penetration into the wall of the uterus can occur during insertion, although the perforation may only be noticed later. If Jaydess lies outside the cavity of the uterus, it cannot effectively prevent pregnancy and must be removed as soon as possible. An operation may be necessary in order to remove Jaydess. The risk of perforation is increased in breastfeeding women and in women up to 36 weeks after a birth, and may be increased in women whose uterus is fixed and tilted backwards (a fixed retroverted uterus). If you suspect that you have a perforation, contact a doctor promptly and remind them that you have a Jaydess in place, particularly if they are not the doctor who inserted it.

Ovarian cyst

Because the contraceptive effect of Jaydess rests mainly on its local action in the uterus, ovulation generally continues to take place while Jaydess is being used. An ovarian cyst may sometimes develop. In most cases this causes no symptoms.

Reporting of side effects

If you get any side effects, talk to your doctor or the healthcare staff. This includes any possible side effects not listed in this leaflet.

Frequently asked questions

Is Jaydess possible if I have not given birth?

Yes, it is particularly suitable for that. The old idea that a coil is something for women who have completed their families is professionally outdated; the professional bodies expressly recommend it for young women too.

From what age is a coil possible?

There is no age limit. What is decisive is the size and shape of the uterus, not the year of birth – both are assessed by ultrasound at the consultation appointment.

Can I leave Jaydess in place for longer than three years?

No. After the licensed period, contraceptive protection is no longer assured. For a longer duration there are Kyleena and Mirena.

Does Jaydess work immediately?

If it is inserted in the first seven days of the cycle, yes. At a later point additional protection with a condom for seven days makes sense.

Does Jaydess help with period pain?

Often yes, because the lining stays thinner. The effect is weaker, though, than with Kyleena and Mirena. With pronounced pain, and particularly where endometriosis is suspected, Mirena is the better choice.

Does Jaydess protect against sexually transmitted infections?

No. For that the condom is the only method – with changing partners, therefore, in addition.
