What is Norethisterone?
Norethisterone is a synthetic progestogen similar to the natural progestogens produced by the body. Together with oestrogen, this hormone plays an important role in women's menstrual cycle and ovulation. Hormonal imbalance can cause health issues such as menstrual problems. Norethisterone restores hormonal balance in the body and so reduces these problems.
What is Norethisterone used for?
Norethisterone is used to treat menstrual disorders such as irregular periods, painful periods (dysmenorrhoea), abnormal vaginal bleeding, endometriosis and menopausal symptoms. Norethisterone can also be used to delay menstrual bleeding.
How to use Norethisterone
Norethisterone can be used in different ways. The doctor will recommend the right treatment for you depending on your symptoms. For most disorders, Norethisterone is taken during the second half of the menstrual cycle. To delay menstrual bleeding you should take the tablets three days before the start of your period for two weeks at the most. For menopausal symptoms and endometriosis, the tablets must be taken continuously and for an extended period of time. Norethisterone tablets should be swallowed whole, without chewing, with plenty of liquid and with food.
Unless otherwise advised by the doctor, the recommended dose for most disorders is:
- one 5-mg tablet once to three times a day for as long as the doctor prescribes.
It is important not to exceed the prescribed dose. This medicine is intended for women only and is not suitable for use in children. Read the package leaflet before use.

- Menstrual spotting or breakthrough bleeding;
- Changes in menstrual bleeding, e.g. irregular bleeding or sometimes stopping of bleeding (usually only with continued use);
- Gastrointestinal symptoms such as stomach ache, nausea, diarrhoea or constipation;
