About Norethisterone

Taking Norethisterone

Start taking one tablet three times a day three days before your period is due.

Norethisterone should not be used for more than 20 days at a time. If you don’t want to wait 17 days for your period, you can get it for less.

After you stop taking Norethisterone, your period should arrive in 2 to 3 days, and your cycles should resume as normal. If you don’t get your period, take a pregnancy test and see your doctor.

Side Effects

Nausea (feeling sick), breast tenderness, tiredness, bloating, decreased sex drive, or headache are all possible side effects.

It has the potential to worsen some chronic diseases in rare cases, but our clinicians will advise you on this. See the patient information leaflet for a complete list of side effects and how to use it correctly. If you have any concerns about side effects, please contact us through your Patient Record.


Norethisterone should be taken three days before your period is due to start, and it should start working right away. If all 20 days of pills are taken, it can delay your period by up to 17 days. You must take three pills per day, and once you stop taking them, your period should begin within a few days.

In-pharmacy checks & collection

This treatment can only be picked up in-store to ensure your safety. Your blood pressure, height, and weight will be checked when you go to the pharmacy to pick up your medication to ensure that this pill is safe for you to take. These checks are completely free and take only a few minutes to complete, and they will take place in a private consultation room.

Because of the increased risk of serious side effects, such as blood clots, Norethisterone may not be appropriate for women with results that are outside of safe limits.

How does it works

The hormone progesterone is synthesized into norethisterone. Rather than allowing your progesterone levels to drop naturally during your period, Norethisterone keeps them high. This causes your period to be delayed by delaying the shedding of your womb lining.

Norethisterone Facts

When taken in the manner required for period delay, norethisterone does not act as a contraceptive, so you should use another method of contraception.

If you’re already on the combined contraceptive pill, you shouldn’t take Norethisterone. If you have a history of blood clots, you should avoid it.

It is not recommended for women who are pregnant or breastfeeding.

Safety: taking other medicines

If you’re already on the combined contraceptive pill, you won’t be able to take Norethisterone.

Norethisterone can be taken with other medications, but as with any medication, there may be some interactions. As a result, it’s critical that you tell us about any prescription, over-the-counter, or recreational drugs you’re taking so that we can safely prescribe Norethisterone.

Treatment options

The only period delay treatment that we provide is norethisterone. Another option is to take the combined pill back to back. This method should be discussed with a pharmacist, contraceptive service, or doctor because it differs depending on the pill. Other alternative treatments that are now available can be discussed with your doctor.
