1. What Brevinor is and what it is used for
Brevinor is one of a group of medicines called combined
oral contraceptives or “the Pill” for short.
Brevinor contains two hormones - a progestogen
hormone called norethisterone and an oestrogen hormone
called ethinylestradiol. These two hormones act together
to prevent pregnancy from occurring.

What you need to know before you take

� Do not take Brevinor:
• if you are allergic to norethisterone, ethinylestradiol
or any of the other ingredients of this medicine
(listed in section 6).
• if you are currently pregnant.
• if you have had blood clots in the legs, blood clots
in varicose veins, the lungs, the brain or elsewhere
(coronary and cerebral thrombotic disorders).
• if you or a member of your family have ever had
a problem with blood clots, including deep vein
thrombosis (DVT).
• if you have had swelling (inflammation) of a vein
caused by a blood clot.
• if you have had a heart attack or stroke or have had
or have angina.
• if you have had or have high levels of fats in your
blood (hyperlipidaemia) or other disorders of body
• if you have had or have cancer of the breast, cervix,
vagina or womb.
• if you have had the following during pregnancy:
• pruritus (itching of the whole body)
• jaundice (yellowing of the skin or eyes), for which
your doctor could not find the cause
• pemphigoid gestationis (a rash previously known
as herpes gestationis typically with blistering of
the palms of the hands and the soles of the feet).
• if you have had or have severe chronic liver disease
(liver tumours, Dubin-Johnson or Rotor syndrome).
• if you have had or have vaginal bleeding, for which
your doctor could not find the cause.
• if you have had or have bad migraines.
• if you have hepatitis C and are taking the medicinal
products containing ombitasvir/paritaprevir/
ritonavir and/or dasabuvir (see also in section ‘Other
medicines and Brevinor’).
� Warnings and precautions
Talk to your doctor or pharmacist before taking Brevinor
if you have any of the following conditions. This will help
them decide if Brevinor is suitable for you:
• Migraine
• Headaches
• Slow or sudden development of visual disturbances
such as complete or partial loss of vision
• Asthma
• Epilepsy (a condition where you suffer from fits)
• Diseases of the heart and blood vessels
(cardiovascular disease)
• High blood pressure (hypertension)
• Kidney disease
• Diabetes
• Multiple sclerosis (a problem of the nervous system)
• Tetany (muscle twitches)
• Breast problems of any sort
• Varicose veins (widened or twisted vein usually in
the leg)
• Liver dysfunction
• Severe depression
• Fibroids in your uterus
• Irregular periods
• Sharp pain in your abdomen
• Gallstones
• Sickle-cell anaemia
• Otosclerosis (an inherited form of deafness)
• Porphyria (a metabolic disease)
• Chloasma (brown patches on your skin which
can happen during pregnancy but may not fade
• Any disease that is likely to get worse during
Possible risk of Thrombosis (Blood Clot)
Some evidence suggests that women who take the Pill
are more likely to develop various blood circulation
disorders than women who don’t take the Pill.
A thrombosis is a blood clot. A thrombosis can develop in
veins or in arteries and can cause a blockage. The chance
of a thrombosis forming in women taking the Pill and
women not taking the Pill is rare. When blood clots form
in arteries they can cause chest pain (angina), strokes
(blood clots in or bleeding from the blood vessels in the
brain) and heart attacks.

If blood clots form in veins they can often be treated, with
no long-term danger. On rare occasions a piece of
thrombosis may break off. It can travel to the lungs to
cause a condition called pulmonary embolism. Therefore
in rare cases a thrombosis can cause serious permanent
disability or could even be fatal.
It is important to note that a thrombosis can form in
people who are not taking the Pill as well as those who
are taking it. The risk is higher in women who take the Pill
than in women who don’t take the Pill, but is not as high
as the risk during pregnancy. The excess risk of
thrombosis is highest during the first year a woman ever
uses a combined oral contraceptive pill.
For healthy non-pregnant women: the chance of having a
blood clot is about 5 in 100,000 each year.
For women taking the Pill containing either levonorgestrel
or norethisterone (a second generation Pill): the chance of
having a blood clot is about 15 in 100,000 each year.
For women taking the Pill containing desogestrel or
gestodene (a third generation Pill): the chance of having a
blood clot is about 25 in 100,000 each year.
For women who are pregnant: the chance of having a
blood clot is about 60 in 100,000 pregnancies.
The risk of heart attacks and strokes for women who use
the combined Pill increases with age and smoking. Other
conditions also increase the risk of blood clots in the
arteries. These include being greatly overweight, having
diseased arteries (atherosclerosis), high blood pressure
during pregnancy (pre-eclamptic toxaemia), high blood
levels of cholesterol, and diabetes. If you have any of
these conditions, you should check with your doctor or
nurse to see if the Pill is suitable for you. Smokers over
35 are usually told to stop taking these pills.
Possible risk of Breast Cancer
Every woman is at risk of breast cancer whether or not
she takes the Pill. Breast cancer is rare under the age of
40 years, but the risk increases as a woman gets older.
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 of finding breast cancer is the same as for
women who have never taken the Pill. Breast cancer
seems less likely to have spread when found in women
who take the Pill than 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 women taking the Pill are
examined more often, so that breast cancer is noticed
earlier. The risk of finding breast cancer is not affected by
how long a woman takes the Pill but by the age at which
she stops. This is because the risk of breast cancer
strongly increases as a woman gets older.
The chart below shows the background chances of breast
cancer at various ages for 10,000 women who have
never taken the Pill (black bars) and for 10,000 women
whilst taking the Pill and during the 10 years after
stopping it (orange bars). The small extra risk of finding
breast cancer can be seen for each age group. This small
possible additional risk in women who take the Pill has to
be balanced against the fact that the Pill is a very
effective contraceptive and it helps prevent cancer of the
womb or ovary.

• There have been some reports on the risk of liver
tumors and cervical cancer associated with the use
of oral contraceptives.
• There is evidence to suggest that the use of
combined oral contraceptives offers protection
against both ovarian and endometrial cancer.
Cervical cancer
Some research suggests an increased risk of getting
cancer of the cervix (neck of the uterus or womb) in
women who take combined oral contraceptives for a long
time. However, this may be due to other causes, such as
sexual behaviour.
Liver cancer
Very rarely, tumours of the liver have been seen in
women taking combined oral contraceptives, especially if
they have been taken for a long time.
If you are worried about any of these things or if you have
had cancer in the past, talk to your doctor to see if you
should take the combined oral contraceptive pill.
Endometrial and ovarian cancer
Research shows that combined oral contraceptives
protect against cancer of the ovary and cancer of the
endometrium (lining of the womb).
If you are going to have a major operation
Make sure your doctor knows about it. You may need to
stop taking Brevinor about 4 weeks before the operation
until at least 2 weeks after the operation and until you are
fully mobile. Alternatively, your doctor may prescribe an
estrogen-free hormonal contraceptive.
Your doctor or nurse will advise whether you can still take
Medical check-ups
Your doctor or nurse will give you regular checkups while
you are taking Brevinor. Your blood pressure will be
checked before you start Brevinor and then at regular
intervals whilst you are on Brevinor. You may be required
to have an examination of your breasts, abdomen and
pelvis including a cervical smear test at regular intervals,
if this is considered necessary by the doctor.
Sexually transmitted diseases
Brevinor helps to prevent pregnancy. It will not protect
against sexually transmitted diseases including AIDS. For
safer sex, use a condom as well as your usual
� Other medicines and Brevinor

3. How to take Brevinor
Always take this medicine exactly as your doctor or
pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
Brevinor can be taken with or without food.
Starting your first blister strip
• Take the first tablet on your first day of bleeding.
This is the day when your period starts. If you are
not having periods, ask your doctor or clinic when
you should start taking your tablets.
• Take the tablet marked with the correct day of the
• You will be protected at once as long as you take a
tablet every day.
• You can take the tablet at a time that suits you, but
you must take it at about the same time every day.
• Take a tablet every day until you finish a blister strip.
• If you cannot start the tablet on the first day of your
period you may start to take it on any day up to the
fifth day. However, if you do this, you may not be
protected for the first seven days, so you should use
another method of contraception such as a condom
during those days.
Starting the next blister strip
• Once you have finished all 21 tablets, stop for
seven days. You will probably bleed during some or
all of these seven days.
• Then, start the next blister strip. Do this whether or
not you are still bleeding. You will always start the
next blister strip on the same day of the week.
• You are protected during the seven day break, but
only if you start the next blister strip on time. The
first tablet in your blister strip is the worst pill of all
to miss or take late.
� If you notice a change in your periods
It is normal that your periods may become irregular and
you may notice some bleeding between periods. Your
periods may become lighter and you may occasionally
have no bleeding during the tablet free days. Make a note
of what happens so that you can tell your doctor or nurse
at your next check-up.
� If you take more Brevinor than you should
Taking too many tablets at once may make you sick,
cause vaginal bleeding or breast swelling. Contact your
doctor or go to your nearest hospital casualty department
� If you forget to take Brevinor
• If you forget to take a tablet take it as soon as you
remember and take the next one at your normal
time. This may mean taking two tablets on the
same day.
• If you are 12 or more hours late in taking one or
more tablets, it may not work. As soon as you
remember, take your last missed tablet and carry
on taking them normally. However, you may not be
protected for the next seven days, so either avoid
sexual intercourse or use an extra contraceptive
method, such as a condom.
• If you have fewer than seven tablets in your blister
strip after you have missed taking a dose, you
should complete the blister strip and start the next
blister strip without a break. This will give you
protection from when you took the last missed
tablet. You may not have a period until the end of
two blister strips, but this will not harm you. You may
also have some bleeding on days when you take the
� If you want to stop taking Brevinor or want to
have a baby?
If you stop taking Brevinor, this will result in the loss of
contraceptive protection and the risk of pregnancy.
If you wish to become pregnant, you should contact your
doctor or nurse about stopping the tablets. It is advisable
to stop taking Brevinor 3 months before you want to start
trying to have a baby.
If you have any further questions on the use of this
product, ask your doctor or pharmacist.
� If you change brands of oral contraceptive
• Take the first tablet of your new blister strip on the
day immediately after you have finished your old
blister strip. Your period will usually be delayed until
the new blister strip is finished, but you may have
some break-through bleeding during the first few
days of the new blister strip. This is quite normal and
you will still be protected against pregnancy.
� If you have a stomach upset or you are sick
• Brevinor may not work if you are sick or have severe
diarrhoea. You should carry on taking the tablets as
normal, but use a condom while you are ill and for
the next seven days. If these seven days run beyond
the end of the blister strip, start the next pack
without a break.
• If you do have a break, ask your doctor or nurse
whether you need an extra contraceptive method,
such as a condom.

� If you have just had a baby
• If you are breast feeding, you should not take the
combined oral contraceptive. This is because the
oestrogen in the tablets may reduce the amount of
milk you produce. You should be able to take another
type of contraceptive instead. Ask your doctor or
nurse for advice.
• If you are not breast feeding, you may start taking
Brevinor 21 days after your baby is born. This will
protect you immediately. If you start later than this,
you may not be protected until you have taken the
tablets for seven days.
� If you have just had a miscarriage or abortion
You may be able to start taking Brevinor immediately. If
you can, you will be protected straight away. Ask your
doctor or nurse if you should do so.
If you have any further questions on the use of this
medicine, ask your doctor or pharmacist.
