Injektion

Norethisterone is a progestogen, which is a female sex hormone similar to the progesterone hormone made naturally by your ovaries. It is an effective and convenient form of short-term Verhütung. The injection will provide contraception for about eight weeks.

Norethisterone works mainly by stopping ovulation (the release of an egg from the ovary). It also changes the lining of your womb (uterus) to make it less likely that an egg would attach to it, even if an egg were to fertilise. In addition, the mucus which forms a plug in the neck of your womb (cervix) becomes thicker. This stops sperm getting through to the womb to fertilise an egg.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before having Noristerat® it is important that your doctor knows:

  • Wenn Sie denken, dass Sie bereits schwanger sein könnten.

  • Wenn Sie Probleme mit der Funktionsweise Ihrer Leber haben.

  • Wenn Sie ein Problem mit Ihren Arterien haben, das als Arterienerkrankung bezeichnet wird.

    • Wenn Sie eine Eierstockzyste haben oder vaginalen Blutungen, die nicht Ihre normale Monatsblutung sind.

    • If you have systemic lupus erythematosus (this is an inflammatory condition, often called SLE).

    • If you have ever had an ectopic pregnancy or if you have developed severe itching of your skin, or yellowing of your skin or the whites of your eyes (jaundice) during a pregnancy.

      • Wenn Sie Brustkrebs hatten oder einen Krebs, von dem Ihnen gesagt wurde, dass er von einem Sexualhormon abhängig ist.

      • Wenn Sie jemals an Depressionen gelitten haben.

      • Wenn Sie eine seltene erbliche Bluterkrankung namens Porphyrie haben.

      • Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

      • If you are taking any other medicines, including those available to buy without a prescription, as well as herbal and complementary medicines. This is because some medicines interfere with the way progestogen contraceptives work.

  • Before you are given the injection you will be asked to read a printed information leaflet from the manufacturer. The manufacturer's leaflet will give you important information about the injection and will provide a full list of the side-effects which you may experience from it. If you have any questions as a result of reading the leaflet, please discuss them with your doctor/nurse before you have the injection. You will be given the leaflet to take home.

  • You will be given the injection by your nurse or doctor. It is usually given during the first 1-5 days of a period. The norethisterone is injected slowly into a muscle in your buttock. From there, it is gradually released into your bloodstream.

  • Your periods are likely to change. Spotting, breakthrough bleeding and delayed periods may occur. Some women have irregular bleeding which can be heavier and longer than normal. Irregular bleeding can sometimes also be due to another reason (such as an infection), so let your doctor know if it happens.

  • Norethisterone injection provides contraception for eight weeks. It is often given as an interim measure - for example, while your partner is having a vasectomy. Make sure your doctor knows if there is any delay to your longer-term plans for contraception.

  • You may gain a little weight. Eating a well-balanced diet and taking regular exercise can help to keep this to a minimum.

  • Untersuchen Sie regelmäßig Ihre Brüste auf Knoten oder Schwellungen. Sprechen Sie mit Ihrem Arzt, wenn Sie Veränderungen bemerken.

  • Bitte beachten Sie: Die Injektion schützt Sie nicht vor HIV (AIDS) oder anderen sexuell übertragbaren Infektionen.

  • Some medicines can reduce the effectiveness of this contraceptive. These include medicines for epilepsy, medicines to treat fungal infections, the herbal preparation St John's wort, and medicines used to treat tuberculosis (TB). Tell the doctor that you have had a progestogen contraceptive injection if you are prescribed any other medicines. If you buy any medicines 'over the counter', ask the pharmacist for advice.
