1. What ZYNTHIA is and what it is used for
ZYNTHIA is used to prevent pregnancy.
There are 2 main kinds of hormone contraceptive.
- The combined pill, "The Pill", which contains 2 types of female sex hormone,
an oestrogen and a progestogen
- The progestogen-only pill, POP or mini-pill, which doesn't contain an
ZYNTHIA is a progestogen-only-pill (POP).
ZYNTHIA contains a small amount of one type of female sex hormone, the
Most POPs work primarily by preventing the sperm cells from entering the womb but
they do not always prevent the egg cell from ripening, which is the main way that
combined pills work.
ZYNTHIA is different from most POPs in having a dose that in most cases prevents
the egg cell from ripening. As a result, ZYNTHIA is a highly effective contraceptive.
In contrast to the combined pill, ZYNTHIA can be used by women who do not
tolerate oestrogens and by women who are breast feeding.
A disadvantage is that vaginal bleeding may occur at irregular intervals during the use of
2. What you need to know before you take
ZYNTHIA, like other hormonal contraceptives, does not protect against HIV infection
(AIDS) or any other sexually transmitted disease.
Do not take ZYNTHIA:
if you are allergic to desogestrel or any of the other ingredients of this medicine
(listed in section 6).
if you have a thrombosis. Thrombosis is the formation of a blood clot in a blood
vessel (e.g. of the legs (deep venous thrombosis) or the lungs (pulmonary embolism)).
if you have or have had jaundice (yellowing of the skin) or severe liver disease and
your liver is still not working normally.
if you have or if you are suspected of having a cancer that grows under the influence
of sex-steroids, such as certain types of breast cancer.
if you have any unexplained vaginal bleeding.
If any of these conditions apply to you, tell your doctor before you start to use ZYNTHIA.
Your doctor may advise you to use a non-hormonal method of birth control. If any of these
conditions appear for the first time while using ZYNTHIA, consult your doctor immediately.
Warnings and precautions
Talk to your doctor or pharmacist before taking ZYNTHIA, if
you have ever had breast cancer.
you have liver cancer, since a possible effect of ZYNTHIA cannot be excluded.
you have ever had a thrombosis.
you have diabetes.
you suffer from epilepsy (See section ‘Taking other medicines’).
you have tuberculosis (See section ‘Taking other medicines’).
you have high blood pressure.
you have or have had chloasma (yellowish-brown pigmentation patches on the skin,
particularly of the face); if so avoid too much exposure to the sun or ultraviolet
When ZYNTHIA is used in the presence of any of these conditions, you may need to be kept
under close observation. Your doctor can explain what to do.
It is important to regularly check your breasts and you should contact your doctor as
soon as possible if you feel any lump in your breasts.
Breast cancer has been found slightly more often in women who take the Pill than in
women of the same age who do not take the Pill. If women stop taking the Pill, this
reduces the risk, so that 10 years after stopping the Pill, the risk is the same as for
women who have never taken the Pill.
Breast cancer is rare under 40 years of age but the risk increases as the woman gets older.
Therefore, the extra number of breast cancers diagnosed is higher if a woman continues to
take the Pill when she is older. How long she takes the Pill is less important.
In every 10 000 women who take the Pill for up to 5 years but stop taking it by the
age of 20, there would be less than 1 extra case of breast cancer found up to 10 years
after stopping, in addition to the 4 cases normally diagnosed in this age group.
In 10 000 women who take the Pill for up to 5 years but stop taking it by the age of
30, there would be 5 extra cases in addition to the 44 cases normally diagnosed.
In 10 000 women who take the Pill for up to 5 years but stop taking it by the age of
40, there would be 20 extra cases in addition to the 160 cases normally diagnosed.
The risk of breast cancer in users of progestogen-only pills like ZYNTHIA is believed to be
similar to that in women who use the Pill, but the evidence is less conclusive.
Breast cancers found in women who take the Pill, seem less likely to have spread than breast
cancers found in women who do not take the Pill.
It is not certain whether the Pill causes the increased risk of breast cancer. It may be that the
women were examined more often, so that the breast cancer is noticed earlier.
See your doctor immediately if you notice possible signs of a thrombosis (see also ‘Regular
Thrombosis is the formation of a blood clot, which may block a blood vessel. A thrombosis
sometimes occurs in the deep veins of the legs (deep venous thrombosis). If this clot breaks
away from the veins where it is formed, it may reach and block the arteries of the lungs,
causing a so-called “pulmonary embolism”. A pulmonary embolism can cause chest pain,
breathlessness, collapse or even death.
Deep venous thrombosis is a rare occurrence. It can develop whether or not you are
taking the Pill. It can also happen if you become pregnant.
The risk is higher in Pill-users than in non-users. The risk with progestogen-only pills like
ZYNTHIA is believed to be lower than in users of Pills that also contain oestrogens
Children and adolescents
No clinical data on efficacy and safety are available in adolescents below 18 years.
Other medicines and ZYNTHIA
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
Some medicines may stop ZYNTHIA from working properly. These include medicines used
for the treatment of
epilepsy (e.g. primidone, phenytoin, carbamazepine, oxcarbazepine, felbamate and
tuberculosis (e.g. rifampicin)
HIV infections (e.g. ritonavir), or other infectious diseases (e.g. griseofulvin)
stomach upset (medical charcoal)
depressive moods (the herbal remedy St. John’s Wort).
Your doctor can tell you if you need to take additional contraceptive precautions and if so, for
ZYNTHIA may also interfere with how certain medicines work, causing either an increase in
effect (e.g. medicines containing cyclosporine) or a decrease in effect.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a
baby, ask your doctor or pharmacist for advice before taking this medicine.
Do not use ZYNTHIA if you are pregnant, or think you may be pregnant.
ZYNTHIA may be used while you are breast-feeding. Desogestrel does not influence the
production or the quality of breast milk. However, a small amount of the active substance of
ZYNTHIA passes over into the milk.
The health of children who were breast-fed for 7 months while their mothers were using
desogestrel has been studied up until they were 2½ years of age. No effects on the growth and
development of the children were observed.
If you are breast-feeding and want to use ZYNTHIA, please contact your doctor.
Driving and using machines
ZYNTHIA has no known effect on the ability to drive or use machines.
ZYNTHIA contains lactose
ZYNTHIA contains lactose (milk sugar). Please contact your doctor before taking ZYNTHIA
if you have been told by your doctor that you are intolerant to some sugars.
When you are using

you notice possible signs of a blood clot (e.g. severe pain or swelling in either of your
legs); unexplained pains in the chest, breathlessness, an unusual cough, especially when
you cough up blood);
you have a sudden, severe stomach ache or jaundice (you may notice yellowing of the
skin, the whites of the eyes, or dark urine, possibly a sign of liver problems);
you feel a lump in your breast (possibly a sign of breast cancer);
you have a sudden or severe pain in the lower abdomen or stomach area (possibly a sign of

How to take ZYNTHIA

Take your tablet each day at about the same time. Swallow the tablet whole,
Arrows are printed on the front of the strip, between the tablets. The days of the week
are printed on the back of the strip. Each day corresponds with one tablet.

tablet from the top row marked (on the back) with WED.

direction indicated by the arrows. By looking at the back of your pack you can easily
check if you have already taken your tablet on a particular day.

Effects) but you must continue to take your tablets as normal.
When a strip is empty, you must start with a new strip of ZYNTHIA on the next day without interruption and without waiting for a bleed.

Take the missed tablet as soon as you remember and take the next one at the usual
time. ZYNTHIA will still protect you from pregnancy.
If you are more than 12 hours late:
If you are more than 12 hours late in taking any tablet, you may not be completely
protected against pregnancy. The more consecutive tablets you have missed, the
higher the risk that you might fall pregnant.
Take a tablet as soon as you remember and take the next one at the usual time. This
may mean taking two in one day. This is not harmful. (If you have forgotten more
than one tablet you don’t need to take the earlier missed ones). Continue to take your
tablets as usual but you must also use an extra method, such as a condom, for the next
If you are more than 12 hours late taking your tablet and have sex it is safe to use
emergency contraception; please consult your pharmacist or doctor.

intercourse in the week before missing the tablets, you may fall pregnant. Ask your
doctor for advice.
