Do not take Primolut N if you are:
R allergic to norethisterone or any of the other ingredients. The ingredients are listed in
section 6
R pregnant or if you think you might be pregnant
R breastfeeding.
or if you have:
R ever had a problem with your blood circulation. This includes a blood clot
(thrombosis) in the legs (deep vein thrombosis), lungs (pulmonary embolism), heart
(heart attack), brain (stroke) or any other parts of the body
R any symptoms of a blood clot, such as chest pain, unexplained and often sudden
shortness of breath and/or cough
R any condition which makes you more at risk of a blood clot (thrombosis)
R ever suffered migraine with visual disturbance
R (or are recovering from) a liver disease and the blood tests show that your liver is not
yet working normally
R (or have ever had) liver tumours.
R diabetes with damaged blood vessels.
R any type of cancer which might be made worse by exposure to female sex
hormones (including breast cancer).

In addition, do not take Primolut N if you have had any of the following conditions when
you were pregnant:
R yellowing of the skin (idiopathic jaundice of pregnancy)
R itching of the whole body (pruritus of pregnancy)
J Tell your doctor if any of these apply to you and do not take Primolut N.
The doctor will take special care:
R if you smoke
R if you have diabetes. Primolut N can produce changes in blood sugar levels. If you
are diabetic, your doctor will check your blood sugar before starting treatment and
regularly during treatment.
R if you are overweight (BMI≥30kg/m2)
R if you have high blood pressure
R if you have a heart valve disorder or a certain heart rhythm disorder (heart
problems)

2. Before you take Primolut N

R if you have had a thrombosis/embolism or anyone in your close family has had a
thrombosis, a heart attack or a stroke at a young age
R if you suffer from migraine, asthma, or kidney problems
R if you suffer from epilepsy (see “Other medicines and Primolut N”)
R if you have an inflammation of your veins (superficial phlebitis)
R if you have varicose veins
R if anyone in your immediate family has had breast cancer
R if you have previously had a condition called chloasma where the skin on your face
may develop brownish blotches. You may be advised to avoid exposure to the sun and
to ultraviolet light while you are taking Primolut N.
R if you have previously suffered from depression.
R if you or someone in your close family has ever had high blood levels of cholesterol
or triglycerides (fatty substances)
R if you have a disease of the liver or gall bladder
R if you have certain rare medical conditions such as systemic lupus erythematosus
(SLE), sickle cell disease, Crohn’s disease or ulcerative colitis
R if you have haemolytic uremic syndrome (‘HUS)’
R if you have a condition that occurred for the first time or worsened during pregnancy
or previous use of sex hormones (e.g. hearing loss, porphyria, or Sydenham‘s
chorea)
R if you have hereditary angioedema. Consult your doctor immediately if you
experience symptoms of angioedema such as swollen face, tongue or throat, and/or
difficulty swallowing, or hives, together with difficulty breathing. Products containing
oestrogens may induce or worsen symptoms of angioedema
R if you have an intolerance to some types of sugar (galactose intolerance, Lapp
lactase deficiency or glucose-galactose malabsorption)
R if you are using other medications as mentioned in “Other Medicines & Primolut N”.
J Tell your doctor before you take Primolut N if any of these applies to you. Also tell
your doctor if any of these conditions develop or worsen while you are taking
Primolut N, because you may need to stop taking it.
Primolut N and blood clots:
The main ingredient in Primolut N (progestogen) is partly converted into oestrogen so you
should also consider the general warnings given for combined oral contraceptive pills
(“the Pill”).
Do not take Primolut N if you have a blood clot or have any medical condition which
makes you more at risk of developing clots.
The risk of blood clots occurring in the veins and arteries is slightly greater in women who
take the combined oral contraceptive pill than in women who don’t. People do not always
fully recover from such blood clots, which can cause strokes, heart attacks and bleeding
into the brain (subarachnoid haemorrhage). In very rare cases these blood clots can be
fatal.

J Please turn over

You are more at risk of having a blood clot:
R as you get older
R if you’re off your feet for a long time because of major surgery, injury or illness.
R if you smoke
R if you or any of your close family have had blood clots
R if you are overweight (BMI ≥ 30kg/m2)
R if you have a disorder of blood fat (lipid) metabolism
R if you have a blood disorder
R if you have high blood pressure
R if you suffer from migraines
R if you have a heart valve disorder or a particular type of irregular heartbeat (atrial
fibrillation)
R if you have recently had a baby
R if you have diabetes
R if you have certain medical conditions such as systemic lupus erythematosus (SLE),
sickle cell disease, Crohn’s disease or ulcerative colitis
J Tell your doctor if any of these apply to you. Taking Primolut N may add to this risk
so it may not be suitable for you.
To reduce the risk of blood clots, treatment with Primolut N must be stopped:
R six weeks before any planned major operation
R before any surgery to the legs
R before medical treatment for varicose veins
R if you are going to be immobilised for a long time (e.g. if you need bed-rest after an
accident or operation, or if you have a plaster cast on a broken leg)
Signs of a blood clot include:
R a migraine for the first time or one that is worse than normal
R unusually frequent or severe headaches
R any sudden changes to your eyesight (such as loss of vision or blurred vision)
R any sudden changes to your hearing, speech, sense of smell, taste or touch
R pain or swelling in your leg
R stabbing pain when you breathe
R coughing for no apparent reason
R breathlessness
R pain and tightness in the chest
R sudden weakness or numbness in one side or part of your body

R dizziness or fainting.
J See a doctor as soon as possible if you notice any possible signs of blood clot. Do
not take any more Primolut N until your doctor says you can.
Primolut N and cancer
If you have breast cancer, or have had it in the past, you should not take combined oral
contraceptives (the Pill). The Pill slightly increases your risk of breast cancer. This risk goes
up the longer you’re on it, but returns to normal within about 10 years of stopping it.
Because breast cancer is rare in women under the age of 40, the extra cases of breast
cancer in current and recent Pill users is small. For example:
R Of 10,000 women who have never taken the Pill, about 16 will have breast cancer by
the time they are 35 years old.
R Of 10,000 women who take the Pill for 5 years in their early twenties, about 17–18
will have breast cancer by the time they are 35 years old.
R Of 10,000 women who have never taken the Pill, about 100 will have breast cancer
by the time they are 45 years old.
R Of 10,000 women who take the Pill for 5 years in their early thirties, about 110 will
have breast cancer by the time they are 45 years old.
Your risk of breast cancer is higher if:
R you have a close relative (mother, sister or grandmother) who has had breast cancer
R you are overweight (BMI ≥ 30kg/m2)
J See a doctor as soon as possible if you notice any changes in your breasts, such
as dimpling of the skin, changes in the nipple or any lumps you can see or feel.
Very rarely, the Pill has been linked with some forms of liver cancer in women who take it
for a long time. These may lead to bleeding in the abdomen.
Taking the Pill has also been linked to liver diseases, such as jaundice and non-cancerous
liver tumours, but this is rare.
J See a doctor as soon as possible if you get severe pain in your stomach that does
not go away, or yellow skin or eyes (jaundice). You may need to stop taking
Primolut N.
Other medicines and Primolut N
J Tell your doctor about any other medicines that you are taking, or took recently.
This includes any products you bought without a prescription.
Some medicines may affect the way Primolut N works. Tell your doctor if you are taking:
R Phenytoin, oxcarbazepine, primidone or carbamazepine. These drugs are often
used to treat epilepsy.
R Sedative drugs called barbiturates.
R The antibiotic drugs rifampicin or rifabutin.
R An antifungal drug called griseofulvin.
R St John’s wort to treat depression.
Some other medicines may be affected by Primolut N. Tell your doctor if you are taking a
drug called ciclosporin which is often used after an organ transplant.

Like all medicines, Primolut N can have side effects – but not everybody gets them.
Reasons for stopping Primolut N immediately:
Stop taking Primolut N and speak to your doctor immediately if you experience any of the
following:
R migraine for the first time
R unusually bad headaches, occurring more often than before
R sudden changes to your eyesight, hearing or speech
R sudden changes to your senses of smell, taste or touch
R symptoms of blood clot formation or symptoms of inflammation of the veins
combined with the formation of blood clots (thrombophlebitis):
P unusual pains in your leg(s)

4. Possible side effects

Take the tablets as instructed by your doctor.
The number of tablets that you need to take and the number of days per month when
you need to take them will depend on why the doctor has prescribed Primolut N. A
common dosage would be 2-3 tablets each day. For some conditions Primolut N has to
be taken every day, but this is not always the case.
Ask your doctor or pharmacist, if you are not sure about the number of tablets that you
need to take, when they should be taken or how long you should take them for.
Swallow the tablets whole with a drink of water.
If you take too many tablets
Taking too many tablets is unlikely to cause serious problems. If you take too many,
contact your doctor who will tell you what to do.
If you forget to take the tablets
If you forget a dose, wait until it is time to take the next prescribed dose. Do not take the
missed dose. If you are worried, contact your doctor or pharmacist.
