About Norethisterone

Norethisterone and the contraceptive pill

Women currently taking a contraceptive pill should not use norethisterone to delay their period.

If using the combined contraceptive pill continuing a new packet straight after your last month's packet will delay your period. However, you cannot do this if taking progestogen-only contraceptive pill or a combined pill which contains dummy (non-active) pills at the end of the pill pack. The way to delay your period depends on the type of combined pill you take – read the NHS Choices page How can I delay my period? for further information.

Norethisterone is NOT a contraceptive and will not prevent pregnancy.

What is norethisterone?

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.

Norethisterone is no longer under patent and is produced by many pharmaceutical companies.

How does it work?

Norethisterone 5mg 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 her 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.

For how long should I take norethisterone?

Dr Fox can supply a maximum of 60 tablets to delay a period for up to 17 days. Fewer tablets are required to delay periods for less than 17 days.

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.

What are the side effects of Norethisterone?

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:

  • Bloating
  • Breast tenderness
  • Loss of libido
  • Fluid retention worsening pre-existing migraine
  • High blood pressure
  • Epilepsy
  • 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.

You can read more about potential side effects in the manufacturer's patient information leaflet supplied with Norethisterone tablets.

Taking other medications

Consult your doctor before taking norethisterone if you regularly take medication for any of the following:

  • Medicines to treat epilepsy (e.g. phenytoin, carbamazepine)
  • Antibiotic medicines to treat an infection (e.g. tetracyclines, rifampicin, co-trimoxazole)
  • Antiviral medicines to treat HIV (e.g. ritonavir, nelfinavir)
  • Anticancer medicines
  • Herbal preparations containing St John's Wort (Hypericum perforatum)
  • Aminoglutethimide, sometimes used in Cushing's syndrome
  • Ciclosporin (for suppressing the immune system)
  • Non-steroidal inflammatory drugs (NSAIDs) for treating pain and inflammation
  • Medicines for high blood pressure

Other cautions to consider

Blood clots in the veins or legs are a common risk for all women and these risks are increased when taking norethisterone, especially if you're very overweight, have suffered previous blood clots in the veins or lungs, have relatives with blood clots, have been immobile for long periods (after an operation, or a long haul flight, for example), have suffered serious injury or major surgery, or have a history of repeated miscarriage.
