What it is and what it is used for

for

Postinor is an emergency contraceptive that can be used within 72 hours (3 days) of unprotected sex or if your usual contraceptive method has failed. Postinor contains a synthetic hormone-like active substance called levonorgestrel. It prevents pregnancy in 99% of situations when you take it within 72 hours of having unprotected sex. It will not prevent a pregnancy every time and is more effective if you take it as soon as possible after unprotected sex. It is better to take it within 12 hours rather than delay until the third day. Postinor is thought to work by: • stopping your ovaries from releasing an egg; • preventing sperm from fertilising any egg you may have already released. Postinor can only prevent you becoming pregnant if you take it within 72 hours of unprotected sex. It does not work if you are already pregnant. If you have unprotected sex after taking Postinor, it will not stop you from becoming pregnant. Postinor is not indicated for use before the first menstrual bleeding (menarche). Postinor is not recommended for young women under 16 years of age.

What you need to know before you take it

e Postinor

Do not use Postinor if you are allergic to levonorgestrel or any of the other ingredients of this medicine (listed in section 6). Warnings and precautions If any of the following applies to you, talk to your doctor before taking Postinor as emergency contraception may not be suitable for you. Your doctor may prescribe another type of emergency contraception for you:

1

•

•

If you are pregnant or think that you may already be pregnant. This medicine will not work if you are already pregnant. If you are already pregnant, Postinor cannot terminate pregnancy, so Postinor is not an "abortion pill". You may already be pregnant if: ­ your period is more than 5 days late, or you have experienced unusual bleeding when your next period is due ­ you have had unprotected sex more than 72 hours ago, and since your last period. Levonorgestrel is not recommended for young women under 16 years of age without medical supervision.

The use of Postinor is not advised if: • you have a disease of your small bowel (such as Crohn's disease) that inhibits the absorption of the drug • you have severe liver problems • you have a history of ectopic pregnancy (where the baby develops somewhere outside the womb) • you have ever had a disease called salpingitis (inflammation of the Fallopian tubes). A previous ectopic pregnancy or previous infection of the fallopian tubes increases the risk of a new ectopic pregnancy. In all women, emergency contraception should be taken as soon as possible after unprotected intercourse. There is some evidence that Postinor may be less effective with increasing body weight or body mass index (BMI), but these data were limited and inconclusive. Therefore, Postinor is still recommended for all women regardless of their weight or BMI. You are advised to speak to a healthcare professional if you are concerned about any problems related to taking emergency contraception. Children and adolescents Postinor is not recommended for young women under 16 years of age. Postinor is not indicated for use before the first menstrual bleeding (menarche). If you are worried about sexually transmitted diseases If you did not use a condom (or if it has been torn or slid down) during the intercourse, it might be possible that you have caught a sexually transmitted disease or the HIV virus. This medicine will not protect you against sexually transmitted diseases, only condoms can do this. Ask your doctor, nurse, family planning clinic or pharmacist for advice if you are worried about this. Other medicines and Postinor Tell your pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription or herbal medicines. Some medicines may prevent Postinor from working effectively. If you have used any of the medicines below during the last 4 weeks, Postinor may be less suitable for you. Your doctor may prescribe another type of (non-hormonal) emergency contraceptive, i.e. a copper intrauterine device (Cu-IUD). If this is not an option for you or if you are unable to see your doctor promptly, you can take a double dose of Postinor: barbiturates and other medicines used to treat epilepsy (for example, primidone, phenytoin, and carbamazepine) medicines used to treat tuberculosis (for example, rifampicin, rifabutin) a treatment for HIV infection (ritonavir, efavirenz) a medicine used to treat fungal infections (griseofulvin) herbal remedies containing St John's wort (Hypericum perforatum). Speak to your pharmacist or doctor if you need further advice on the correct dose for you.

Consult your doctor as soon as possible after taking the tablets for further advice on a reliable form of regular contraception and to exclude a pregnancy (also see section 3 "How to take Postinor" for further advice). Postinor may also affect how well other medicines work: a medicine called ciclosporin (suppresses the immune system). Consult a doctor or pharmacist before using Postinor if you use any of the above mentioned medicines. How often can you use Postinor You should only use Postinor in emergencies and not as a regular method of contraception. If Postinor is used more than once in a menstrual cycle, it is less reliable and it is more likely to upset your menstrual cycle (period). Postinor does not work as well as regular methods of contraception. Your doctor, practice nurse or family planning clinic can tell you about long-term methods of contraception which are more effective in preventing you from getting pregnant. Pregnancy, breast-feeding and fertility If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Pregnancy You should not take this medicine if you are already pregnant. If you do become pregnant even after taking this medicine, it is important that you see your doctor. There is no evidence that Postinor will harm a baby that develops in your uterus/womb if you use Postinor as described. Nevertheless, your doctor may want to check that the pregnancy is not ectopic (where the baby develops somewhere outside the womb). This is especially important if you develop severe abdominal pain after taking Postinor or if you have previously had an ectopic pregnancy, Fallopian tube surgery or pelvic inflammatory disease. Breast-feeding Very small amounts of the active ingredient of this medicine may appear in your breast milk. This is not thought to be harmful to the baby, but if you are worried you can take your tablet immediately after a breast-feeding and avoid nursing at least 8 hours following tablet taking. In this way you are taking your tablet well before the next feed and reducing the amount of active ingredient your baby may take in with the breast milk. Fertility Postinor increases the possibility of menstruation disturbances which can sometimes lead to earlier or later ovulation date. These changes can result in modified fertility date, however there are no fertility data in the long term. Driving and using machines Your Postinor tablet is unlikely to affect your ability to drive a car or use machines. However, if you feel tired or dizzy do not drive or operate machinery. Postinor contains lactose In case of milk sugar (lactose) intolerance it should be considered that each Postinor tablet also contains 142.5 mg lactose monohydrate. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

How to take it

Postinor

Always use this medicine exactly as described in the leaflet or as your pharmacist has told you. Check with your doctor or pharmacist if you are not sure. Take the tablet as soon as possible, preferably within 12 hours, and no later than 72 hours (3 days) after you have had unprotected sex. Do not delay taking the tablet. The tablet works best the sooner you take it after having unprotected sex. It can only prevent you becoming pregnant, if you take it within 72 hours of unprotected sex. • Postinor can be taken at any time in your menstrual cycle assuming you are not already pregnant or think you may be pregnant. Do not chew but swallow the tablet whole with water. • If you are using one of the medicines that may prevent Postinor from working properly (see section above "Other medicines and Postinor") or if you have used one of these medicines in the past 4 weeks, Postinor may work less effectively for you. Your doctor may prescribe another type of (non-hormonal) emergency contraceptive, i.e. a copper intrauterine device (Cu-IUD). If this is not an option for you or if you are unable to see your doctor promptly, you can take a double dose of Postinor (i.e. 2 tablets taken together at the same time). • If you are already using a regular method of contraception such as the contraceptive pill, you can continue to take this at your regular times. If another unprotected intercourse takes place after the use of Postinor (also if this is during the same menstrual cycle), the tablet will not exert its contraceptive effect and there is again the risk of pregnancy. What to do if you are sick (vomit) If you are sick (vomit) within three hours of taking the tablet, you should take another tablet. You will need to contact your pharmacist, doctor, practice nurse or family planning clinic immediately for one more tablet. After you have taken Postinor After you have taken Postinor, if you want to have sex, and are not using the contraceptive pill, you should use condoms or a cap plus spermicide until your next menstrual period. This is because Postinor won't work if you have unprotected sex again, before your next period is due. After you have taken Postinor, you are advised to make an appointment to see your doctor about three weeks later, to make sure that Postinor has worked. If your period is more than 5 days late or is unusually light or unusually heavy, you should contact your doctor as soon as possible. If you do become pregnant even after taking this medicine, it is important that you see your doctor. Your doctor can also tell you about longer-term methods of contraception which are more effective in preventing you from getting pregnant. If you continue to use regular hormonal contraception such as the contraceptive pill and you do not have a bleed in your pill-free period, see your doctor to make sure you are not pregnant. Your next period after you took Postinor After the use of Postinor, your period is usually normal and will start at the usual day; however sometimes, this will be a few days later or earlier. If your period starts more than 5 days later than expected, an 'abnormal' bleeding occurs at that time or if you think that you might be pregnant, you should check whether you are pregnant by a pregnancy test. If you take more Postinor than you should Although there have been no reports of serious harmful effects from taking too many tablets at once, you may feel sick, actually be sick (vomit), or have vaginal bleeding. You should ask your pharmacist, doctor, practice nurse or family planning clinic for advice, especially if you have been sick, as the tablet may not have worked properly. If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Technical information intended for healthcare professionals (doctors and pharmacists). The Summary of Product Characteristics (SmPC) is the official document approved by the MHRA/EMA. It does not replace the patient leaflet or a doctor’s advice.

4.1. Therapeutic indications

Emergency contraception within 72 hours of unprotected sexual intercourse or failure of a contraceptive method.

Postinor is indicated in adults and adolescents >16 years of age.

4.2. Posology and method of administration

Posology

One tablet should be taken, as soon as possible, preferably within 12 hours, and no later than 72 hours after unprotected intercourse (see section 5.1).

Women who have used enzyme-inducing drugs during the last 4 weeks and need emergency contraception are recommended to use a non-hormonal EC, i.e. Cu-IUD or take a double dose of levonorgestrel (i.e. 2 tablets taken together) for those women unable or unwilling to use Cu-IUD (see section 4.5).

If vomiting occurs within three hours of taking the tablet, another tablet should be taken immediately.

Postinor can be used at any time during the menstrual cycle unless menstrual bleeding is overdue.

After using emergency contraception it is recommended to use a local barrier method (e.g. condom, diaphragm, spermicide, cervical cap) until the next menstrual period starts. The use of levonorgestrel does not contraindicate the continuation of regular hormonal contraception.

Paediatric population

There is no relevant use of Postinor for children of prepubertal age in the indication emergency contraception

Method of administration

For oral administration.

4.3. Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

4.4. Special warnings and precautions for use

Emergency contraception is an occasional method. It should in no instance replace a regular contraceptive method.

Emergency contraception does not prevent a pregnancy in every instance. If there is uncertainty about the timing of the unprotected intercourse or if the woman has had unprotected intercourse more than 72 hours earlier in the same menstrual cycle, conception may have occurred. Treatment with levonorgestrel following the second act of intercourse may therefore be ineffective in preventing pregnancy. If menstrual periods are delayed by more than 5 days or abnormal bleeding occurs at the expected date of menstrual periods or pregnancy is suspected for any other reason, pregnancy should be excluded. If pregnancy occurs after treatment with levonorgestrel, the possibility of an ectopic pregnancy should be considered. The absolute risk of ectopic pregnancy is likely to be low, as levonorgestrel prevents ovulation and fertilisation. Ectopic pregnancy may continue, despite the occurrence of uterine bleeding.

Therefore, levonorgestrel is not recommended for patients who are at risk of ectopic pregnancy (previous history of salpingitis or of ectopic pregnancy).

Levonorgestrel is not recommended in patients with severe hepatic dysfunction.

Severe malabsorption syndromes, such as Crohn's disease, might impair the efficacy of levonorgestrel.

This medicinal product contains lactose monohydrate. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

After levonorgestrel intake, menstrual periods are usually normal and occur at the expected date. They can sometimes occur earlier or later than expected by a few days. Women should be advised to make a medical appointment to initiate or adopt a method of regular contraception. If no withdrawal bleed occurs in the next pill-free period following the use of levonorgestrel after regular hormonal contraception, pregnancy should be ruled out.

Repeated administration within a menstrual cycle is not advisable because of the possibility of disturbance of the cycle.

Limited and inconclusive data suggest that there may be reduced efficacy of Postinor with increasing body weight or body mass index (BMI) (see sections 5.1 and 5.2). In all women, emergency contraception should be taken as soon as possible after unprotected intercourse, regardless of the woman's body weight or BMI.Levonorgestrel is not as effective as a conventional regular method of contraception and is suitable only as an emergency measure. Women who present for repeated courses of emergency contraception should be advised to consider long-term methods of contraception.

Use of emergency contraception does not replace the necessary precautions against sexually transmitted diseases.

4.5. Interaction with other medicinal products and other forms of interaction

The metabolism of levonorgestrel is enhanced by concomitant use of liver enzyme inducers, mainly CYP3A4 enzyme inducers. Concomitant administration of efavirenz has been found to reduce plasma levels of levonorgestrel (AUC) by around 50%.

Drugs suspected of having similar capacity to reduce plasma levels of levonorgestrel include barbiturates (including primidone), phenytoin, carbamazepine, herbal medicines containing Hypericum perforatum (St. John's Wort), rifampicin, ritonavir, rifabutin and griseofulvin.

For women who have used enzyme-inducing drugs in the past 4 weeks and need emergency contraception, the use of non-hormonal emergency contraception (i.e. a Cu-IUD) should be considered. Taking a double dose of levonorgestrel (i.e. 3000 microgram within 72 hours after the unprotected intercourse) is an option for women who are unable or unwilling to use a Cu-IUD, although this specific combination (a double dose of levonorgestrel during concomitant use of an enzyme inducer) has not been studied.

Medicines containing levonorgestrel may increase the risk of cyclosporin toxicity due to possible inhibition of cyclosporin metabolism.

Women taking such drugs should be referred to their doctor for advice.

4.6. Fertility, pregnancy and lactation

Pregnancy

Levonorgestrel should not be given to pregnant women. It will not interrupt a pregnancy. In the case of continued pregnancy, limited epidemiological data indicate no adverse effects on the fetus but there are no clinical data on the potential consequences if doses greater than 1.5 mg of levonorgestrel are taken (see section 5.3.).

Breast-feeding

Levonorgestrel is secreted into breast milk. Potential exposure of an infant to levonorgestrel can be reduced if the breast-feeding woman takes the tablet immediately after feeding and avoids nursing at least 8 hours following levonorgestrel administration.

Fertility

Levonorgestrel increases the possibility of cycle disturbances which can sometimes lead to earlier or later ovulation date. These changes can result in modified fertility date, however, there are no fertility data in the long term.

4.7. Effects on ability to drive and use machines

No studies on the effect on the ability to drive and use machines have been performed.

4.8. Undesirable effects

The most commonly reported undesirable effect was nausea.
