30 x 5MG TABLETS
Norethisterone is a man-made form of progesterone, a naturally occurring female sex hormone and is used for a number of reasons. It cannot be used as hormone replacement therapy (HRT). Medium-strength tablets can treat heavy periods and are even used for some female cancers, such as breast cancer.
How does it work?
Norethisterone tablets can be taken three times daily to delay periods. Start tablets at least 3 days before the start of a period and continue for as long as needed. A period bleed will normally start 2 to 3 days, and possibly longer, after stopping Norethisterone. As a woman’s hormone balance changes during a menstrual cycle, taking Norethisterone tablets during menstruation will delay a period.
Norethisterone should not be used by women taking the contraceptive pill. Consult your GP or contraception specialist about delaying periods whilst taking contraceptives. Norethisterone is NOT a contraceptive and will not prevent pregnancy.
Norethisterone is only designed to be taken occasionally and should not be requested more than once every 4 months. If you need to delay a period for more than 17 days, you should consult your GP.
Are there any side effects?
All medications are prone to causing side effects and you’re more likely to suffer them if you take Norethisterone long-term, but the most common side effects are:
- Breast tenderness
- Loss of libido
- Fluid retention worsening pre-existing migraine
- High blood pressure
- Jaundice (yellowing of the skin due to liver disease)
In rare cases, Norethisterone can cause a severe allergic reaction that can, in some instances, be life-threatening. Early symptoms of this include difficulty breathing, wheezing, feeling faint, swelling of the tongue or face, intense and itchy skin rash, and swelling of the hands and feet.
