About Norethisterone Tablets - 5mg
  1. What is Norethisterone?

    Norethisterone is a medicine that is used in birth control pills; it is often prescribed for women to delay a period. Typically, Norethisterone is used to delay a period for a holiday, wedding or another specific event. It should not be taken for this purpose continually.

    You need a prescription to buy Norethisterone tablets.

    What is Norethisterone used to treat?

    Norethisterone is commonly prescribed for women to delay their period. It is also prescribed to help women who suffer from irregular periods, or painful or heavy periods.

    It is a synthetic progestogen, which is similar to the natural female sex hormone progesterone.

    There is no specific reason you must give a doctor for medication to delay your period, and most women have considered delaying their period for convenience. For example, if you are getting married you may wish to delay your period to stop it from coming on the big day.

    Norethisterone tablets are designed to be taken in isolated events. They should not be used to permanently prevent your period from occurring.

    Norethisterone as a hormonal replacement therapy

    When taken in combination with oestrogen, norethisterone is also used in hormonal replacement therapy (HRT).

    Hormone replacement therapy most commonly involves taking a combination of oestrogen and progesterone (combined HRT). Taking oestrogen on its own increases the risk of endometrial cancer.

    Why is Norethisterone prescribed for delaying periods?

    Clinical trials have shown Norethisterone to be a safe and highly effective period delay medication. 

    These tablets can be used safely to delay your period for up to 17 days, although you should not use them to delay periods regularly.

    Norethisterone cannot stop a period from occurring if it has already started, it must be taken 3 days before you are expected to start your period.

    How does Norethisterone delay periods?

    Norethisterone is a synthetic progestogen designed to mimic progesterone, which is a naturally occurring hormone within the body. During a menstrual cycle, the level of progesterone in the body drops, which causes the lining of the womb to shed and a period to commence. Norethisterone tops up the naturally occurring levels of progesterone, which prevents a period from taking place.

    Before a woman gets her period, the progesterone levels in her body will normally fall. Taking Norethisterone will sustain the lining of your womb and delay a period until you stop taking the tablets.

    Who can take Norethisterone?

    Norethisterone may not be suitable for all women to use. Speak to your doctor if you are not sure if this medication is suitable for you.
