About Norethisterone

Norethisterone is a synthetic hormone which mimics the effect of the bodies naturally occurring hormone progesterone. It can have multiple uses, however, it is often used as a tablet to delay periods. Norethisterone comes as a 5mg tablet and can be taken to delay periods for up to 17 days.

Norethisterone is NOT a method of contraception. It is s therefore important that you should continue to use contraceptive methods if you do not want to become pregnant. Norethisterone should also not be taken if you are already taking the combined contraceptive pill. You can, however, take it while taking the mini pill. Norethisterone is not suitable for pregnant or breastfeeding women.

Taking Norethisterone for Period Delay

If you are taking norethisterone to delay your period, there are a few things you should know. Firstly, it's important you can predict when your period is due. As long as this is known, you should start taking norethisterone three days before your period is due to start. One 5mg tablet is taken THREE times daily. When you want your period to start, simply stop taking the medication. After stopping, your period should start 1-2 days later. 

You can take Norethisterone for up to 20 days in total, meaning that you can delay your period for around 17 days.


If you are already taking a combined oral contraceptive pill such as Microgynon, you can delay your period without the need for Norethisterone, or the branded version, Utovlan.

You will need to have taken the pill for at least a whole month prior to your current menstrual cycle. To delay your period, simply take two months of your combined pill back to back, without having a 7 day pill-free break, or using your inactive pills.

NOTE: This method does not work with the "mini-pill" (progesterone only pills), such as Cerazette.



  • How Do I Take Norethisterone?

    To delay your period, Norethisterone should be taken three days before your period is due. It should be taken three times daily for each day you want to delay your period. This should be done for a maximum period of 17 days. After stopping norethisterone, your period should start 2-3 days after.

  • How Does Norethisterone Work?

    Norethisterone works by keeping levels of the female hormone, progesterone, in the body up. This, in turn, stops your womb lining from shedding, and so delaying your period. Norethisterone is basically a synthetic version of progesterone.

  • When will my period start again?

    Your period should start around 2 days after stopping taking Norethisterone.

  • Can I use norethisterone for heavy periods?

    No. Norethisterone supply is ntended only to delay your period temporarily. You should speak to your GP if you  require regular treatment for heavy periods.

  • What is norethisterone?

    Norethisterone is a synthetic version of progesterone, which is a sex hormone produced by the body.

  • Can I become pregnant when using period delay tablets?

    Yes. Norethisterone is not a contraceptive, so you should use a method of birth control in order to avoid becoming pregnant.
