Norethisterone is an artificial version of the female hormone progesterone. In the 5mg strength, Norethisterone is primarily used for period delay.

There may be times when it is inconvenient to have a period (wedding day, holidays etc.) and Norethisterone tablets can delay your period for up to 17 days.

Norethisterone delays your period by mimicking the effect of natural progesterone in the body. It prevents the lining of the womb from being shed and means there is no blood to form a period.

Starting three days before you expect your period, take one tablet with a glass of water three times a day for as long as you would like to delay you period.

Your period will start 2-3 days after you stop taking the tablets.

Norethisterone tablets can be taken with or without food.

If you need to delay you period for longer than 17 days or on more than one occasion in a 4 month period, we recommended you speak to a Doctor.

Norethisterone is very effective if it is taken regularly three times a day - if you miss a dose you may experience some bleeding or spotting. The tablets have to be started before your period has begun. It will not be effective after your period has started.

Norethisterone comes in different strengths and it is used to treat different conditions depending on the strength. It can be used as a contraceptive but this is at a strength of 350 micrograms.

It is important to use another form of contraception whilst taking Norethisterone 5mg tablets to delay your period, as it won’t prevent a pregnancy. There are lots of different contraception options available and a Doctor will be able to explain the options that are right for you.

If you are taking a combined contraceptive pill (containing both oestrogen and progesterone), there may be no need to take period delay tablets.

There are three different types of combined contraceptive pills:

Monophasic: These contain 21 tablets in a strip and each tablet contains the same amount of hormone(s). After the last tablet you have a 7-day break. To delay your period you may run two strips of pills back to back without a break.

ED (Every Day): There are 21 tablets of one colour and 7 white tablets at the end of a strip. The white tablets are dummy tablets. To delay your period discard the 7 white tablets at the end of the strip and start the next strip without a break.

Phasic: There are 21 tablets in a packet but the level of hormone in each pill varies depending on where you are in your cycle. Ask us or your Doctor for advice on which pills you can miss out. Examples of phasic contraceptive pills include Synphase, Triadene, Logynon, Binovum & Trinovum.

It is not recommended to run more than 2 strips of contraceptive pill back-to-back.

If you still wish to use Norethisterone 5mg tablets to delay your period even though you are taking a combined oral contraceptive pill, there is no problem.

There are different types Progesterone-only pills, however running two packets back to back will not delay your period.

You can either speak to your Doctor about switching to a combined oral contraceptive or take Noresthiorone 5mg tablets to delay your period. Switching to a combined contraceptive may take several weeks to be effective and is not suitable for everyone.

Norethisterone can be taken for a maximum of 17 days in a row to delay your period. This cannot be repeated within four months. If you want to delay your period for longer or more frequently, we recommended seeing your Doctor first to discuss the most suitable option for you.

Side effects are normally seen when Norethisterone is taken long-term basis rather than for short courses to delay periods. The most common unwanted effects include bloating, loss of libido, tender breasts and stomach pains.

Norethisterone can also cause fluid retention in some women. If this occurs it can worsen pre-existing conditions like epilepsy, migraines, asthma and high blood pressure. If this occurs you should speak to your doctor as soon as possible.

There is no interaction between Norethisterone and alcohol.
