Why is this medication prescribed?

This is combined oral hormonal contraceptive medication used to prevent pregnancy (Ethinyl estradiol 35mcg + Norethisterone 1mg tablets).

Ethinylestradiol/Norethisterone contains two hormones that are similar to the hormones oestrogen and progesterone that are produced by the body. Ethinylestradiol/Norethisterone is used to prevent women from becoming pregnant. It works by preventing the release of eggs from the ovary and changes the lining of the uterus which makes it difficult for an egg to develop. It also increases the thickness of vaginal fluid which can stop a sperm from reaching an egg.

Ethinylestradiol/Norethisterone may increase the chances of developing blood clots, breast cancer or cervical cancer. However, it may provide some protection against ovarian and endometrial cancer. You and your prescriber will need to weigh up the benefits and risks of taking Ethinylestradiol/Norethisterone before you start to take it.

Hormonal contraceptives will only prevent a pregnancy if they are taken regularly. It is important you take this medicine at the same time each day. If you want immediate contraceptive cover then start to take Ethinylestradiol/Norethisterone on the first day of your menstrual period. If you do not start taking Ethinylestradiol/Norethisterone on the first day of your menstrual period you will need to take extra contraceptive precautions for at least seven days until Ethinylestradiol/Norethisterone starts to work. For more information about starting Ethinylestradiol/Norethisterone and if you need to take extra contraceptive precautions ask your prescriber, family planning nurse or read the patient information leaflet that comes with your medicine.

Once you have started to take Ethinylestradiol/Norethisterone, you should take it once a day for 21 days. After this you should not take any more tablets for the next seven days. Start a new strip of Ethinylestradiol/Norethisterone immediately after the seven day tablet-free break. During this break you will usually have a withdrawal bleed. If you do not have a withdrawal bleed during the tablet-free break and you have taken all your pills properly, you are very unlikely to be pregnant. However, if you miss a withdrawal bleed and you have not taken your tablets properly or if you miss two withdrawal bleeds in a row you should immediately contact your prescriber or family planning nurse. This is because there is a possibility that you could be pregnant and Ethinylestradiol/Norethisterone may harm a baby if taken during pregnancy.

In certain situations the effectiveness of Ethinylestradiol/Norethisterone may be reduced and you will need to take extra contraceptive precautions. These situations include: missing a dose by more than 12 hours; taking other medicines that interact with Ethinylestradiol/Norethisterone; having diarrhoea or an upset stomach or any medical condition which interferes with the absorption of your medicine. If any of these situations occur during the last seven days of your strip you should not have a tablet-free break between strips of tablets. Start taking the next strip of tablets without a break.

As there is no gap between strips you will not have a withdrawal bleed at the end of the first strip. But you may have some menstrual bleeding while you are taking the second strip and you should have a withdrawal bleed once you finish the second strip. For more information about situations when the effectiveness of Ethinylestradiol/Norethisterone may be reduced and when to take additional contraceptive precautions ask your prescriber, family planning nurse or read the patient information leaflet that comes with your medicine.
