What is in Noristerat and who makes it
- 1. What Noristerat is and what it is used for
Noristerat is an injectable (depot) contraceptive. It is intended as a short-term method of contraception, for example in women whose partners are undergoing vasectomy, until the vasectomy is effective. It is also for use in women immunised against rubella, to prevent pregnancy while the virus is active.
You use it to stop you getting pregnant.
Noristerat contains a type of female sex hormone, called a progestogen. This hormone stops you getting pregnant by working in three ways: by preventing an egg being released from your ovaries; by making the fluid (mucus) in your cervix thicker, which makes it more difficult for sperm to enter the womb; and by preventing the lining of your womb thickening enough for an egg to grow in it.
The benefits of using Noristerat include:
RR it is one of the most reliable reversible
methods of contraception if used correctly
RR you only have to remember to visit
your doctor after 8 weeks for a second injection
RR it doesn’t interrupt sex
Noristerat will not protect you against sexually transmitted infections, such as Chlamydia or HIV. Only condoms can help to do this.
- 2. Make sure Noristerat is OK for you
It’s important that you understand the benefits and risks of using Noristerat before you are given it, or when deciding whether to have a second injection. Although Noristerat is suitable for most healthy women it isn’t suitable for everyone.
MM Tell your doctor if you have any of
the illnesses or risk factors mentioned in this leaflet.
Before you are given Noristerat
RR Your doctor will ask about you and
your family’s medical problems, check your blood pressure and exclude the likelihood of you being pregnant. You may also need other checks, such as a breast examination, but only if these
examinations are necessary for you, or if you have any special concerns. While you’re on Noristerat
RR Check your breasts and nipples every
month for changes – tell your doctor if you can see or feel anything odd, such as lumps or dimpling of the skin. RR If you need a blood test or other
laboratory tests, tell your doctor or the laboratory staff that you are using Noristerat, because hormonal contraceptives can affect the results of some tests.
RR If you’re going to have an
operation, make sure your doctor knows about it. You may need to avoid having a second injection of Noristerat before the operation. This is to reduce the risk of a blood clot (see section 2.1).
2.1 Noristerat and blood clots Noristerat may slightly increase your risk of having a blood clot (called a thrombosis), especially in the first year of using it.
A clot in a leg vein – a deep vein thrombosis (or DVT) – is not always serious. However, if it moves up the veins and blocks an artery in the lungs, it can cause chest pain, breathlessness, collapse or even death. This is called a pulmonary embolism and is very rare.
Very rarely, blood clots can also form in the blood vessels of the heart (causing a heart attack) or the brain (causing a stroke). In healthy young women the chance of having a heart attack or stroke is extremely small.
You are more at risk of having a blood clot:
RR as you get older
RR if you smoke
RR if you are seriously overweight RR if you have some diseases of the
heart and blood vessels
RR if you suffer from migraines RR if you have recently had a baby RR if you’re off your feet for a long
time because of major surgery, injury or illness
MM Tell your doctor if any of these risk
factors apply to you. Noristerat may not be suitable for you.
Signs of a blood clot include:
RR a migraine for the first time, a
migraine that is worse than normal, or unusually frequent or severe headaches
RR any sudden changes to your
eyesight (such as loss of vision or blurred vision)
RR any sudden changes to your
hearing, speech, sense of smell, taste or touch
RR pain or swelling in your leg RR stabbing pain when you breathe RR coughing for no apparent reason RR pain and tightness in the chest RR sudden weakness or numbness in
one side or part of your body RR dizziness or fainting.
MM See a doctor as soon as possible. Do
not have a further injection until your doctor says you can. Use another method of contraception, such as condoms, in the meantime.
2.2 Noristerat and cancer
Noristerat has also been linked to liver diseases, such as jaundice and non-cancer liver tumours, but this is rare. Very rarely, Noristerat has also been linked with some forms of liver cancer in women who have used it for a long time.
MM See a doctor as soon as possible if
you get severe pain in your stomach, or yellow skin or eyes (jaundice). You may need to stop using Noristerat .
2.3 Noristerat should not be used by some women
MM Tell your doctor or family planning
nurse if you have any medical problems or illnesses.
Do not use Noristerat if you have any of the problems listed below. Using Noristerat would put your health at risk. RR If you are pregnant or might be
pregnant
RR If you have 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
RR If you have or have ever had severe
liver disease, and you have been told by your doctor that your liver function test results are not yet back to normal
RR If you have or have ever had liver
tumours
RR If you have severe diabetes
affecting your blood vessels
RR If you have very high blood pressure RR If you have disorders of blood fat
(lipid) metabolism
RR If you have or suspect you have cancer
affected by sex hormones – such as some cancers of the breast or womb lining or have ever had either of these conditions
RR If you have an inherited disease called
porphyria
RR If you are allergic (hypersensitive) to
norethisterone enantate or any of the other ingredients in Noristerat (listed in section 6).
MM If you suffer from any of these, or
get them for the first time while using Noristerat, contact your doctor as soon as possible. It may not be suitable for you to have a second injection of Noristerat.
2.4 Noristerat can make some illnesses worse
Some of the conditions listed below can be made worse by using Noristerat. Or they may mean it is less suitable for you. You may still be able to be given Noristerat but you need to take special care.
RR If you have had severe depression RR If you have ever had liver problems,
e.g. jaundice (yellow skin or eyes) RR If you have any disease that tends to
get worse during pregnancy
RR If you have an irregular menstrual
pattern together with stomach pains
RR If you have abnormal vaginal
bleeding
RR If you have diabetes
RR If you have ever had an ectopic
pregnancy or fallopian tube removed.
The main ingredient of Noristerat (the progestogen, norethisterone enantate) is partly converted into the oestrogen, ethinylestradiol. The expected
concentration of ethinylestradiol in your body is relatively low compared to taking combined hormonal contraceptives containing ethinylestradiol. This means that although effects similar to those after taking combined hormonal
contraceptives containing ethinylestradiol cannot be completely ruled out, experience to date suggests that this may not be the case.
MM Tell your doctor or family planning
nurse if any apply to you. Also tell them if you get any of these for the first time after being given Noristerat, or if any get worse or come back, because it may not be suitable for you to have a second injection of Noristerat.
2.5 Psychiatric disorders
Some women using hormonal
contraceptives including Noristerat have reported depression or depressed mood. Depression can be serious and may sometimes lead to suicidal thoughts. If you experience mood changes and depressive symptoms contact your doctor for further medical advice as soon as possible.
2.6 Taking other medicines
If you ever need to take another medicine or herbal products at the same time, always tell your doctor, pharmacist or dentist that you’ve been given Noristerat. Also check the leaflets that come with all your medicines to see if they can be taken with hormonal contraceptives.
Some medicines can stop Noristerat from working properly – for example: RR certain sedatives (called
barbiturates)
RR some medicines used to treat epilepsy
RR some medicines used to treat HIV and Hepatitis C virus infections
(so-called protease inhibitors and non-nucleoside reverse transcriptase inhibitors)
RR griseofulvin (an anti-fungal
medicine)
RR phenylbutazone (an anti-
inflammatory medicine)
RR certain antibiotics
RR St John’s Wort (a herbal remedy). If you do need to take one of these medicines, you may need to use extra contraception (for example condoms) for a while. Your doctor, pharmacist or dentist can tell you if this is necessary and for how long.
Noristerat can also affect how well other medicines work. For example, if you have diabetes, you may need to take Q!
more insulin or other anti-diabetic drugs after being given Noristerat. Your doctor will tell you if this is necessary.
2.7 Using Noristerat with food and drink
There are no special instructions about food and drink while on Noristerat
2.8 Pregnancy and breast-feeding Pregnancy
You should not be given Noristerat if you are pregnant. If you think you might be pregnant, do a pregnancy test to confirm that you are and do not have your second injection.
Breast-feeding
Noristerat has not been shown to reduce the amount of milk you produce which is an advantage if you wish to breastfeed your baby. Very small amounts of the hormone are found in breast milk. There is no evidence to suggest that the small amounts of the hormone that appear in the milk are harmful to a healthy baby. However, if your baby has severe or long-lasting jaundice that requires medical treatment you should not breast-feed your baby after having your injection.
2.9 Driving and using machines
Noristerat has no known effect on the ability to drive or use machines.
2.10 Noristerat contains benzyl benzoate
This medicine contains 333.8 mg benzyl benzoate in each 1 ml ampoule. Benzyl benzoate may increase jaundice (yellowing of the skin and eyes) in newborn babies (up to 4 weeks old).
3. How to use Noristerat
3.1 How to start
Your doctor or family planning clinic will give you the first injection of Noristerat within the first five days of your period (unless you start just after a pregnancy or an abortion). The injection is given into the muscle.
By starting in this way you will have contraceptive protection at once.
3.2 Further injections of Noristerat
One injection will give you contraception for 8 weeks. After 8 weeks a second injection can be given. You must make sure that you leave no longer than 8 weeks between injections or contraceptive protection will be lost.
3.3 Starting Noristerat after having a baby
Noristerat can normally be used straight after having a baby. Your doctor will advise you on when to start.
3.4 Starting Noristerat after having a miscarriage or an abortion
You may be able to have an injection immediately. Your doctor will advise you.
3.5 Missed a period – could you be pregnant?
If, when the second injection is due, you have not had a further period since the first injection, it is unlikely that you are pregnant, but the second injection should not be given until pregnancy has been ruled out.
3.6 Being given more Noristerat than you should
Overdosage is unlikely but if it does occur no serious ill-effects are expected.
4. Possible side effects
