6. What is in Noristerat and who makes it

• 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.

• 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.
• 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.
• 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).

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:

• as you get older
• if you smoke
• if you are seriously overweight
• if you have some diseases of the heart and blood vessels
• if you suffer from migraines
• if you have recently had a baby
• if you’re off your feet for a long time because of major surgery, injury or illness

• 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:

• a migraine for the first time, a migraine that is worse than normal or unusually frequent or severe headaches
• any sudden changes to your eyesight (such as loss of vision or blurred vision)
• any sudden changes to your hearing, speech, sense of smell, taste or touch
• pain or swelling in your leg
• stabbing pain when you breathe
• coughing for no apparent reason
• pain and tightness in the chest
• sudden weakness or numbness in one side or part of your body
• dizziness or fainting.

• 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.

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.

• 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 .

• 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.

• If you are pregnant or might be pregnant
• 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
• 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
• If you have or have ever had liver tumours
• If you have severe diabetes affecting your blood vessels
• If you have very high blood pressure
• If you have disorders of blood fat (lipid) metabolism
• 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
• If you have an inherited disease called porphyria
• If you are allergic (hypersensitive) to norethisterone enantate or any of the other ingredients in Noristerat (listed in section 6).

• 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.

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.

• If you have had severe depression
• If you have ever had liver problems, e.g. jaundice (yellow skin or eyes)
• If you have any disease that tends to get worse during pregnancy
• If you have an irregular menstrual pattern together with stomach pains
• If you have abnormal vaginal bleeding
• If you have diabetes
• 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.

• 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.

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.

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:

• certain sedatives (called barbiturates)
• some medicines used to treat epilepsy
• some medicines used to treat HIV and Hepatitis C virus infections (so-called protease inhibitors and non-nucleoside reverse transcriptase inhibitors)
• griseofulvin (an anti-fungal medicine)
• phenylbutazone (an anti-inflammatory medicine)
• certain antibiotics
• 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 more insulin or other anti-diabetic drugs after being given Noristerat. Your doctor will tell you if this is necessary.

There are no special instructions about food and drink while on Noristerat

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.

Noristerat has no known effect on the ability to drive or use machines.

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).

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.

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.

Noristerat can normally be used straight after having a baby. Your doctor will advise you on when to start.

You may be able to have an injection immediately. Your doctor will advise you.

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.

Overdosage is unlikely but if it does occur no serious ill-effects are expected.

Signs of a blood clot:

• a migraine for the first time, a migraine that is worse than normal or unusually frequent or severe headaches
• any sudden changes to your eyesight (such as loss of vision or blurred vision)
• any sudden changes to your hearing, speech, sense of smell, taste or touch
• pain or swelling in your leg
• stabbing pain when you breathe
• coughing for no apparent reason
• pain and tightness in the chest
• sudden weakness or numbness in one side or part of your body
• dizziness or fainting.

Signs of a severe allergic reaction to Noristerat:

• swelling of the face, lips, mouth, tongue or throat.

Signs of severe liver problems include:

• severe pain in your upper abdomen
• yellow skin or eyes (jaundice)
• inflammation of the liver (hepatitis)
• your whole body starts itching.

• If you think you may have any of these, see a doctor straight away. You may need to stop using Noristerat.

• irregular bleeding
• bloating
• tender breasts
• headaches
• depressive moods
• dizziness
• feeling sick
• putting on weight
• skin reactions (e.g. pain or itchy rash) at the injection site
• rarely coughing for no apparent reason, shortness of breath and disturbances of the circulatory system may develop while you are having your injection, or immediately after.

• Tell your doctor or family planning nurse if you are worried about any side effects which you think may be due to Noristerat. Also tell them if any existing conditions get worse while you are using Noristerat.

If you get any side effects, talk to your doctor, family planning nurse or pharmacist. This includes any possible side effects not listed in this leaflet.
