e Norgeston
It's important that you understand the benefits and risks of taking the Pill before you start taking it, or when deciding whether to carry on taking it. Although the Pill is suitable for most healthy women it isn't suitable for everyone. ➜ Tell your doctor if you have any of the illnesses or risk factors mentioned in this leaflet. Before you start taking the Pill
of a blood clot (see section 2.1). Your doctor will tell you when you can start taking the Pill again. 2.1 The Pill and blood clots The Pill may slightly increase your risk of having a blood clot (called a thrombosis), especially in the first year of taking 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:
2.2 The Pill and cancer If you have breast cancer, or have had it in the past, you should not take the Pill. The Pill slightly increases your risk of breast cancer. This risk goes up the longer you're on the Pill, 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: Page 3 of 10 v020_0
▪
In 10,000 women who take progestogen-only pills like Norgeston for up to 5 years but stop taking it by the time they are aged 20, it is estimated that less than 1 additional case of breast cancer would be found up to 10 years afterwards, compared with the number found in 10,000 women who had never taken the Pill.
▪
For 10,000 women who take the Pill like Norgeston for 5 years and stop it by the age of 30, there would be 2 or 3 extra cases of breast cancer found up to 10 years afterwards (in addition to the 44 cases of breast cancer found in 10,000 women in this age group who had never taken the Pill).
▪
For 10,000 women who take Norgeston for 5 years and stop it by the age of 40, there would be about 10 extra cases found up to 10 years afterwards (in addition to 160 cases of breast cancer found in 10,000 women in this age group who had never taken the Pill).
Your risk of breast cancer is higher:
2.3 Norgeston should not be taken by some women ➜ Tell your doctor or family planning nurse if you have any medical problems or illnesses. Do not take Norgeston if any of the following apply to you. Taking Norgeston would put your health at risk. ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪
If you are pregnant or might be pregnant If you have ever had a severe liver disease and have been told by your doctor that your liver function test results are not yet back to normal If you have ever had liver tumours If you have cancer affected by sex hormones -such as current or history of breast cancer If you have vaginal bleeding that has not been explained by your doctor 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 severe diabetes with changes to the blood vessels If you are allergic (hypersensitive) to any of the ingredients in Norgeston.
➜ If you suffer from any of these, or get them for the first time while taking Norgeston, contact your doctor as soon as possible. Do not take Norgeston and use another method of contraception.
Page 4 of 10 v020_0
2.4 Norgeston can make some illnesses worse Some of the conditions listed below can be made worse by taking Norgeston, or they may mean it is less suitable for you. Remind your doctor: ▪ ▪ ▪ ▪ ▪ ▪
If you have diabetes If you have ever had a pregnancy develop outside the womb (an ectopic pregnancy) or one of your Fallopian tubes is missing If you have ovarian cysts If you have ever suffered from yellowing of the skin (jaundice) If you have ever suffered from persistent itching (pruritus) If you have brown patches on your face or body (chloasma). If so avoid too much exposure to the sun or ultraviolet radiation.
➜ Tell your doctor or family planning nurse if any of these apply to you. Also tell them if you get any of these for the first time while taking Norgeston, or if any of these or any problems which you had previously during pregnancy or whilst taking an oral contraceptive get worse or come back, because you may need to stop taking Norgeston. 2.5
Psychiatric disorders
Some women using hormonal contraceptives including Norgeston 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, including medicines obtained without a prescription, at the same time as being on the Pill, always tell your doctor, pharmacist or dentist that you're taking Norgeston. Also check the leaflets that come with all your medicines to see if they can be taken with hormonal contraceptives. Some medicines can stop Norgeston from working properly and cause unexpected bleeding – for example:
Page 5 of 10 v020_0
Norgeston can also affect how well other medicines work. For example, taking Norgeston can mean that the levels of some drugs in your blood may either go up (e.g. ciclosporin) or go down (e.g. lamotrigine). Norgeston may also increase or reduce the effects of some anticoagulant drugs (e.g. coumarins) or inhibit the anticoagulant effect (e.g. phenindione). Laboratory tests Norgeston can interfere with the results of some blood tests, so always tell your doctor that you are taking Norgeston if you have a blood test. 2.7 Taking Norgeston with food and drink There are no special instructions about food while on Norgeston. 2.8 Pregnancy and breast-feeding Do not use Norgeston if you are pregnant. If you think you might be pregnant, do a pregnancy test to confirm that you are before you stop taking Norgeston. Progestogen-only pills like Norgeston have not been shown to have any detrimental effect on breast milk or the growth or development of a healthy baby. 2.9 Driving and using machines Norgeston has no known effect on the ability to drive or use machines. 2.10 Norgeston contains lactose and sucrose If you have been told by your doctor that you have intolerance to some sugars, contact your doctor before using Norgeston.
3 Taking Norgeston 3.1 How to take it To prevent pregnancy, always take Norgeston as described below. Check with your doctor or family planning nurse if you are not sure. Take Norgeston every day for 35 days Norgeston comes in strips of 35 pills, each marked with a day of the week.
As a new user or starting the Pill again after a break It is best to take your first Norgeston pill on the first day of your next period. Another method of contraception will not be required. Changing to Norgeston from another contraceptive Pill •
• •
If you are currently on a combined oral contraceptive, vaginal ring or patch: If you have correctly and consistently used the previous combined Pill, start taking Norgeston the day after your last active pill (discarding the placebo pills or disregarding the pill-free interval). If a vaginal ring or transdermal patch has been used correctly and consistently before the switch, start using Norgeston on the day of removal of the last vaginal ring or transdermal patch of a cycle pack and thereby omit the hormone-free interval of this product. Another method of contraception will not be required. Changing from another progestogen-only pill (POP or 'mini Pill'): you can start taking Norgeston at any time without the loss of contraceptive protection. Changing from a progestogen-only parenteral method (implant, injection): additional non -hormonal contraceptive protection (e.g. a condom) are not required if you start exactly when the next implant or injection is due.
Starting Norgeston after a miscarriage or abortion If you have had a miscarriage or an abortion during the first three months of pregnancy, your doctor may tell you to start taking Norgeston straight away, in which case another method of contraception will not be required. Contraception after having a baby If you have just had a baby your doctor will advise you to start taking Norgeston immediately after delivery. If you start taking Norgeston later than this you should use another method of contraception, such as a condom for the first 7 days of pill taking. If you have already had intercourse, then you should exclude the possibility of pregnancy before starting Norgeston or wait until you have your first period. If you have just had a baby and you are breast feeding please refer to section 2.8 Pregnancy and Breast-feeding. 3.3 A missed pill If you are less than 3 hours late with a pill, take it straight away. Keep taking your pills at the usual time. This may mean taking two pills in one day. Don't worry – your contraceptive protection should not be reduced. If you are more than 3 hours late with a pill, or you have missed more than one pill, your contraceptive protection may be reduced. ▪ ▪
Continue to take your next pills at your usual time. Use extra contraception for the next 7 days, such as condoms.
If you have missed any of the pills in a strip and had intercourse in the week before missing the tablets, there is a possibility of becoming pregnant. The more consecutive tablets you have missed, the higher the risk that the contraceptive efficacy is decreased. 3.4 A lost pill If you lose a pill,
Page 7 of 10 v020_0
Either take the last pill of the strip in place of the lost pill. Then take all the other pills on their proper days. When you start your next pack you will have a new starting day, one day earlier than before. Or if you have another pack and do not want to change the starting day of your next strip, take a pill from that pack. Then take all the other pills from your current strip as usual. You can then keep the opened spare strip in case you lose any more pills. 3.5 If you are sick or have diarrhoea If you are sick (vomit) within 2 hours of taking a tablet your body may not get its usual dose of hormones from that pill and you should take another pill as soon as possible. Follow the instructions in section 3.4 A lost pill. If you are not able to take another pill within 3 hours use extra contraception for the next 7 days, such as condoms If you are persistently sick or have very bad diarrhoea, use extra contraception during the illness and for the 7 days after recovery, such as condoms 3.6 Taking more than one pill should not cause harm It is unlikely that taking more than one pill will do you any harm, but you may feel sick, vomit or have some vaginal bleeding. Talk to your doctor if you have any of these symptoms. 3.7 When you want to get pregnant If you are planning a baby, it's best to use another method of contraception after stopping Norgeston until you have had a proper period. Your doctor or midwife relies on the date of your last natural period to tell you when your baby is due. However, it will not cause you or the baby any harm if you get pregnant straight away.
4 Possible side effects Like all medicines, Norgeston can cause side effects, although not everybody gets them. ➜ Tell your doctor, pharmacist or family planning nurse if you are worried about any side effects which you think may be due to Norgeston. 4.1 Serious side effects – see a doctor straight away Signs of a blood clot:
▪
any lumps you can see or feel.
Signs of severe liver problems include:
bleeding and spotting between your periods no periods allergic reactions, including wheezing, rash or reddened skin. depressive moods, loss of interest in sex headaches or migraine dizziness feeling sick or being sick putting on weight or losing weight.
➜ Tell your doctor, pharmacist or family planning nurse if you are worried about any side effects which you think may be due to Norgeston. Also tell them if any existing conditions get worse while you are taking Norgeston. 4.3 If your periods seem different A few women have irregular periods, a little unexpected bleeding or spotting or no periods at all while they are taking Norgeston, especially during the first few months. Normally, these changes are nothing to worry about and require no treatment. Keep taking Norgeston as usual. The problem should disappear after the first few strips. You may also have unexpected bleeding if you are not taking your pills regularly, so try to take your pill at the same time every day. Also, unexpected bleeding can sometimes be caused by other medicines. ➜ ▪
▪
Make an appointment to see your doctor if you get breakthrough bleeding or spotting that: o carries on for more than the first few months o starts after you've been taking Norgeston for a while o carries on even after you've stopped taking Norgeston. you have had no period for 6 weeks.
Reporting of side effects If you get any side effects, talk to your doctor or pharmacist or nurse. This includes any possible

Oral contraception.
First treatment cycle: One tablet daily, starting on the first day of the menstrual cycle, at a time of day chosen by the patient. All subsequent tablets must then be taken at this time. The contraceptive effect is likely to be reduced if a tablet is delayed by more than three hours. Additional contraceptive precautions are not necessary when initiating treatment.
Subsequent cycles: The tablets are taken daily and pack follows pack without interruption, and without regard to bleeding.
Changing from a combined oral contraceptive (COC), vaginal ring, or transdermal patch: If the woman has correctly and consistently used the previous COC, the first tablet of Norgeston should be taken on the first day after the last active tablet of the COC pack (In the case of every day (ED) tablet use, the inactive ones should be omitted). If a vaginal ring or transdermal patch has been used correctly and consistently before the switch, the woman should start using Norgeston on the day of removal of the last vaginal ring or transdermal patch of a cycle pack and thereby omit the hormone-free interval of this product. Additional contraceptive precautions are not required.
Changing from another POP: The switch can be made at any time without interruption of contraceptive protection.
Changing from a progestogen-only parenteral method (implant, injection): The switch should be made before or when the next injection or implant is due.
Post-partum use: Norgeston can be initiated up to 21 days post-partum (no additional contraceptive is required). If started after 21 days additional barrier contraceptive methods should be used for 7 days. However, if intercourse has already occurred, pregnancy should be excluded before the actual start of Norgeston use or the woman has to wait for her first menstrual period. For additional information on breast feeding women see section 4.6
Post-abortion or miscarriage use After a first trimester abortion, Norgeston may be started at the time of the abortion or miscarriage. Additional contraceptive precautions will not then be required. If started after this time barrier contraceptive methods should be used for 7 days.
Special circumstances requiring additional contraception:
Management of missed pills: If the user forgets a pill she should take it as soon as she remembers and carry on with the next pill at the same time. If the pill was more than 3 hours overdue (> 27 hours since the last pill was taken) she will not be protected from pregnancy. She should continue normal pill taking but must also use barrier contraceptive methods for the next 7 days. If intercourse took place in the preceding 7 days, the possibility of a pregnancy should be considered. The more tablets are missed, the higher the risk of a pregnancy.
Gastro-intestinal upsets: If vomiting occurs within 2 hours of taking a tablet, another pill should be taken as soon as possible. If a replacement pill is not taken within 3 hours of the scheduled time, additional, barrier contraceptive methods should be used for 7 days.
In cases of persistent vomiting and/or very severe diarrhoea, additional barrier contraceptive methods should be used during the illness and for 7 days after recovery.
Paediatric population
There is no relevant indication for the use of Norgeston before menarche
Geriatric patients
Not applicable. Norgeston is not indicated after menopause.
Patients with hepatic impairment
Norgeston is contraindicated in women with severe hepatic diseases. See also section 4.3.
Patients with renal impairment
Norgeston has not been specifically studied in renally impaired patients.
Norgeston should not be used in the presence of any of the conditions listed below. Should any of the conditions appear during the use of Norgeston, the use of the preparation must be discontinued immediately.
• Known or suspected pregnancy.
• Presence or history of severe hepatic disease as long as liver function values have not returned to normal.
• History of or existing thromboembolic processes (e.g. stroke, myocardial infarction).
• Presence or history of liver tumours (benign or malignant).
• Known or suspected sex- steroid influenced malignancies (e.g. current or history of breast cancer).
• Undiagnosed abnormal vaginal bleeding.
• Severe diabetes with vascular changes.
• Hypersensitivity to the active substance or to any of the excipients.
Medical Examination
Assessment of women prior to starting oral contraceptives (and at regular intervals thereafter) should include a personal and family medical history of each woman. Physical examination should be guided by this and by the contraindications (section 4.3) and warnings (section 4.4) for this product. The frequency and nature of these assessments should be based upon relevant guidelines and should be adapted to the individual woman, but should include measurement of blood pressure.
Exclude the likelihood of pregnancy before starting treatment.
Warnings
The benefits of using Norgeston should be weighed against the possible risks for each individual woman and discussed with the woman before she decides to start using it. In the event of aggravation, exacerbation or first appearance of any of these conditions or risk factors, the woman should contact her physician. The physician should then decide on whether Norgeston should be discontinued.
Women should be advised that oral contraceptives do not protect against HIV infections (AIDS) and other sexually transmitted diseases.
Reasons for stopping Norgeston immediately.
When stopping oral contraception non-hormonal contraception should be used to ensure contraceptive protection is maintained.
1. Occurrence for the first time, or exacerbation, of migrainous headaches or unusually frequent or unusually severe headaches.
2. Sudden disturbances of vision or hearing or other perceptual disorders.
3. First signs of thrombophlebitis or thromboembolic symptoms (for example, unusual pains in or swelling of the legs, stabbing pains on breathing or coughing for no apparent reason), feeling of pain and tightness in the chest.
4. Six weeks before an elective major operation (e.g. abdominal, orthopaedic) any surgery to the legs, medical treatment for varicose veins or prolonged immobilisation e.g. after accidents or surgery. Do not restart until 2 weeks after full ambulation. In case of emergency surgery, thrombotic prophylaxis is usually indicated e.g. subcutaneous heparin.
5. Onset of jaundice, hepatitis, itching of the whole body.
6. Clear exacerbation of conditions known to be capable of deteriorating during oral contraception or pregnancy (e.g. recurrence of cholestatic jaundice and/or pruritus which occurred first during pregnancy or previous use of sex steroids).
7. Pregnancy is a reason for stopping immediately because it has been suggested by some investigations that oral contraceptives taken in early pregnancy may slightly increase the risk of foetal malformations. Other investigations have failed to support these findings. The possibility therefore cannot be excluded, but it is certain that if a risk exists at all it is very small.
Circulatory Disorders
In the few epidemiological studies conducted, which are limited in the number of subjects, there is little evidence for an association between progestogen only pills and an increased risk of myocardial infarction and cerebral thromboembolism. The risk of cardiovascular and cerebral events is rather related to increasing age, hypertension, and smoking. In women with hypertension the risk of stroke may be slightly enhanced by progestogen-only pills.
There may be a slightly, but not statistically significant increased risk of venous thromboembolism (deep venous thrombosis, pulmonary embolism) associated with the use of progestogen-only pills. Generally recognized risk factors for venous thromboembolism (VTE) include a positive personal or family history (VTE in a sibling or a parent at a relatively early age), age, obesity and prolonged immobilization, major surgery or major trauma.
Tumours
• Breast Cancer
A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk of having breast cancer diagnosed in women who are currently using oral contraceptives (OC). The observed pattern of increased risk may be due to an earlier diagnosis of breast cancer in OC users, the biological effects of OCs or a combination of both. The additional breast cancers diagnosed in current users of OCs or in women who have used OCs in the last 10 years are more likely to be localised to the breast than those in women who never used OCs.
Breast cancer is rare among women under 40 years of age whether or not they take OCs. Whilst the background risk increases with age, the excess number of breast cancer diagnoses in current and recent progestogen-only pill (POP) users is small in relation to the overall risk of breast cancer, possibly of similar magnitude to that associated with combined OCs. However, for POPs, the evidence is based on much smaller populations of users and so is less conclusive than that for combined OCs. Available studies do not provide evidence for causation.
The most important risk factor for breast cancer in POP users is the age women discontinue the POP; the older the age at stopping, the more breast cancers are diagnosed. Duration of use is less important and the excess risk gradually disappears during the course of the 10 years after stopping POP use, such that by 10 years there appears to be no excess.
The evidence suggests that compared with never-users, among 10,000 women who use POPs for up to 5 years but stop by age 20, there would be much less than 1 extra case of breast cancer diagnosed up to 10 years afterwards. For those stopping by age 30 after 5 years use of the POP, there would be an estimated 2-3 extra cases (additional to the 44 cases of breast cancer per 10,000 women in this age group never exposed to oral contraceptives). For those stopping by age 40 after 5 years use, there would be an estimated 10 extra cases diagnosed up to 10 years afterwards (additional to the 160 cases of breast cancer per 10,000 never-exposed women in this age group).
It is important to inform patients that users of all contraceptive pills appear to have a small increase in the risk of being diagnosed with breast cancer, compared with non-users of oral contraceptives, but that this has to be weighed against the known benefits.
• Liver Cancer
In rare cases benign, and in even rarer cases, malignant liver tumours leading in isolated cases to life-threatening intra-abdominal haemorrhage have been observed after the use of hormonal substances such as the one contained in Norgeston. If severe upper abdominal complaints, liver enlargement or signs of intra-abdominal haemorrhage occur, a liver tumour should be included in the differential diagnostic considerations.
Other conditions
• Diabetes
Diabetes mellitus or tendency towards diabetes mellitus requires careful medical supervision.
• Ectopic Pregnancy
If there is a history of ectopic pregnancy or one Fallopian tube is missing, the use of Norgeston should be decided on only after carefully weighing the benefits against the risks.
If obscure lower abdominal complaints occur together with an irregular cycle pattern (above all amenorrhoea followed by persistent irregular bleeding), an extrauterine pregnancy must be considered.
• Persistent ovarian follicles
Persistent ovarian follicles (often referred to as functional ovarian cysts) may occur during the use of Norgeston. Most of these follicles are asymptomatic, although some may be accompanied by pelvic pain or dyspareunia. In most cases, the enlarged follicles disappear spontaneously during two to three months of observation.
• Psychiatric disorders
Depressed mood and depression are well-known undesirable effects of hormonal contraceptive use (see section 4.8). Depression can be serious and is a well-known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in case of mood changes and depressive symptoms, including shortly after initiating the treatment.
• Chloasma
Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation whilst taking Norgeston.
• Lactose and Sucrose intolerance
Each tablet of this medicinal product contains 32.97 mg lactose and 19.66 mg sucrose per tablet. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency, fructose intolerance or glucose-galactose malabsorption or sucrase-isomaltase should not take this medicine.
• Bleeding patterns
Menstrual changes: A usual feature of all progestogen-only oral contraceptives is that they can produce an initial irregularity of the bleeding pattern, but such irregularity tends to decrease with time. Some women may experience amenorrhoea.
For these reasons the possibility of such changes in menstrual rhythm should, as a precaution, be pointed out to the patient before the start of tablet-taking.
Amenorrhoea / Missed menstruation: If no menstrual bleeding has occurred within 6 weeks after the last menstrual bleeding, pregnancy must be excluded before tablet-taking is continued. If pregnancy has been excluded and the amenorrhoea lasts longer than 3 months or recurs repeatedly, Norgeston should be withheld until normal menstrual bleeding has been restored.
Procedure in the event of irregular bleeding: Irregular bleeding is not a medical reason for stopping tablet-taking, as long as organic causes for such bleeding and pregnancy can be ruled out provided it is ensured that the patient is fully compliant.
It is extremely inadvisable to attempt to influence cycle disturbances by the additional administration of an oestrogen. This would only serve to reverse the changes brought about by Norgeston in the cervical mucus, thereby seriously reducing the contraceptive effect.
Note: The prescribing information of concomitant medications should be consulted to identify potential interactions.
Effects of other medicinal products on Norgeston
Interactions can occur with drugs that induce microsomal enzymes, which can result in an increased clearance of sex hormones and which may lead to breakthrough bleeding and oral contraceptive failure. This has been established with many hepatic enzyme-inducing drugs.
Enzyme induction can already be observed after a few days of treatment. Maximal enzyme induction is generally seen within a few weeks. After the cessation of drug therapy enzyme induction may be sustained for about 4 weeks.
Short-term treatment
Women on treatment with enzyme-inducing drugs should temporarily use a barrier method or another method of contraception in addition to Norgeston. The barrier method must be used during the whole time of the concomitant drug therapy and for 28 days after its discontinuation. If the drug therapy runs beyond the end of the tablets in the Norgeston pack, the next Norgeston pack should be started right after the previous one.
Long-term treatment
In women on long-term treatment with hepatic enzyme-inducing active substances, another reliable, non-hormonal, method of contraception is recommended.
Substances increasing the clearance of levonorgestrel (diminished efficacy of Norgeston by enzyme-induction), e.g.:
Phenytoin, barbiturates, primidone, carbamazepine, rifampicin and possibly also oxcarbazepine, topiramate, felbamate, griseofluvin and products containing St. John's wort (Hypericum perforarum).
Substances with variable effects on the clearance of levonorgestrel
When co-administered with sex hormones, many HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors can increase or decrease plasma concentrations of the progestin.
The net effect of these changes may be clinically relevant in some cases.
Therefore, the prescribing information of concomitant HIV/HCV medications should be consulted to identify potential interactions and any related recommendations. In case of any doubt, an additional barrier contraceptive method should be used for those women on protease inhibitor or non-nucleoside reverse transcriptase inhibitor therapy.
Substances decreasing the clearance of levonorgestrel (enzyme inhibitors)
Strong and moderate CYP3A4 inhibitors such as azole antifungals (e.g. fluconazole, itraconazole, ketoconazole, voriconazole), verapamil, macrolides (e.g. clarithromycin, erythromycin), diltiazem and grapefruit juice can increase plasma concentrations of levonorgestrel. The clinical relevance of potential interactions with enzyme inhibitors remains unknown.
Effects of Norgeston on other medicinal products
Progestogens may affect the metabolism of certain other drugs. Accordingly, plasma and tissue concentrations may be increased (e.g. ciclosporin) or decreased (e.g. lamotrigine). Progestogens may either enhance or reduce the anticoagulant effects of coumarins and may antagonize the anticoagulant effects of phenindione.
Other forms of interaction
Effect on blood chemistry:
The use of oral contraceptives may influence the results of certain laboratory tests including biochemical parameters of liver, thyroid, adrenal and renal function, plasma levels of carrier proteins and lipid/lipoprotein fractions, parameters of carbohydrate metabolism and parameters of coagulation and fibrinolysis. Laboratory staff should therefore be informed about oral contraceptive use when laboratory tests are requested.
The administration of Norgeston during pregnancy is contraindicated.
If pregnancy occurs during medication with Norgeston the preparation is to be withdrawn immediately.
Epidemiological studies have revealed neither an increased risk of birth defects in children born to women who used oral contraceptives prior to pregnancy, nor a teratogenic effect when oral contraceptives were taken inadvertently during early pregnancy.
Hormonal contraceptives are not recommended as the contraceptive method of first choice during lactation, but progestogen-only methods are considered to comprise the next choice category after non-hormonal methods. Progestogen-only pills, like Norgeston, can be used by breast feeding women as there appears to be no evidence to suggest that progestogen-only pills have a detrimental effect on breast milk or infant growth or development. A breast-feeding woman can start a progestogen-only treatment, like Norgeston, up to 21 days post-partum without the need for additional contraceptive protection. When starting later, the woman should be advised to additionally use a barrier method for the first 7 days of tablet taking. However, if intercourse has already occurred, pregnancy should be excluded before the actual start of Norgeston use or the woman has to wait for her first menstrual period.
None known.
Summary of the safety profile:
The most commonly reported adverse reactions with progestogen-only pills including Norgeston are uterine/vaginal bleeding including spotting, menorrhagia and/or metrorrhagia and amenorrhea. They occur in ≥ 10 % of users.
The undesirable effects are mapped to the respective System Organ Class (SOC), based on MedDRA v. 13.1. The SOCs are listed in the international order of MedDRA SOCs:
Immune system disorders
Allergic reaction
Metabolism and nutrition disorders
Increased or decreased weight
Psychiatric disorders
Depressed mood
Nervous system disorders
Migraine, Headache, Dizziness
Gastrointestinal disorders
Vomiting, Nausea
Reproductive system and breast disorders
Changes in vaginal bleeding pattern (including irregular bleeding, amenorrhoea)
Decreased or increased libido
The following serious adverse events have been reported in women using OCs, which are discussed in section 4.4 'Special warnings and precautions for use':
• Venous thromboembolic disorders
• Arterial thromboembolic disorders
• Strokes (e.g. transient ischemic attack, ischemic stroke, haemorrhagic stroke)
• Benign and malignant liver tumours leading in isolated cases to life-threatening intra-abdominal haemorrhage
• Diabetes mellitus or tendency towards diabetes mellitus require careful medical supervision.
• A history of ectopic pregnancy or a missing Fallopian tube require careful weighing of the benefits of Norgeston against the risks.
