Norethisterone tablets are pills to stop your period. They can be used to delay your period, for example when going on holiday. Norethisterone tablets need to be taken three days before you expect your period to begin and delay your period until three days after you have taken the last tablet.

More information

What do period delay tablets do?

Period delay tablets are a treatment used to stop your period for a set amount of time (up to 30 days with norethisterone). Period delay tablets are not contraceptives, so you can’t use them to protect against pregnancy.

There are 2 main types of period delay tablet available in the UK:

  • Norethisterone 5mg
  • Medroxyprogesterone 10mg

Both of these types of period delay tablets use a version of the hormone progesterone. This hormone is used by your body to help time your periods. When the level of progesterone in your body drops, that’s the signal to start another period. If you’re taking progesterone tablets then you trick your body into waiting a little longer before starting the next period.

Norethisterone is licensed specifically for period delay, but medroxyprogesterone technically isn’t. This doesn’t mean medroxyprogesterone isn’t safe, though. From a doctor’s point of view they’re both safe to use for period delay.
