ABOUT Norethisterone Tablets

Buy Norethisterone tablets to delay periods

You can buy norethisterone tablets to stop periods for a special occasion, such as a wedding or holiday. You will need to complete a short online questionnaire, to ensure that treatment is suitable.

What is norethisterone?

Norethisterone is a synthetic version of progesterone, a hormone involved in regulating the menstrual cycle in women. Norethisterone 5mg can be used as a period delay tablet. Other norethisterone uses include the treatment of certain medical conditions such as endometriosis, heavy periods, or painful periods. It is also used in IVF treatment. 

How does norethisterone work?

Progesterone levels fluctuate throughout the course of the month. Towards the end of the cycle, progesterone levels drop, causing the lining of the womb to break down and it is expelled via bleeding. This is known as a period. Norethisterone works by keeping levels of progesterone elevated, so that the lining of the womb is not broken down. This stops bleeding. Once you stop taking norethisterone, progesterone levels will drop, causing a bleed.

Norethisterone dosage for period delay

To delay menstruation, you should “Take ONE norethisterone 5mg tablet, THREE times a day, starting three days before your period is due”.

How to take norethisterone

You can take one tablet with a glass of water. Food does not affect the absorption of the tablet, so it does not matter whether you take it before or after a meal.

What if I forget to take a tablet?

If you forget to take a dose of norethisterone, take it as soon as you remember. If you remember when it is time for your next dose, do not take two tablets together

Norethisterone side effects

Like all medication, norethisterone may cause side effects, although not everyone will get them.

Common side effects of norethisterone include:

  • irregularities to the menstrual cycle. This can include bleeding or spotting in between periods. 
  • feeling sick
  • tenderness of the breasts
  • fatigue
  • bloating
  • lower than usual sex drive
  • headache

You should read the patient information leaflet for a full list of side effects, and what to look out for.

Are there side effects after stopping treatment?

Norethisterone is not likely to cause any long-term side effects. After stopping treatment, any side effects should go away within a few days.

Who cannot take norethisterone tablets?

You should not take norethisterone if you are using the following:

  • Any hormonal contraceptive methods, such as the coil (hormonal), or contraceptive pills, patches, implants, vaginal rings or depot injections.

You should speak to your doctor in the following instances:

  • You are epileptic or taking medication to treat epilepsy
  • You have cancer or you are using cancer treatment
  • You have a history or family history of blood clots
  • You have a heart condition, or you are at risk of developing heart problems
  • You suffer from migraines
  • You are taking antiviral medication
  • You are using immunosuppressants
  • You are using anti-inflammatory medication

How quickly does norethisterone stop bleeding?

Norethisterone tablets are taken three days before the expected onset of a period, so no bleeding should occur until treatment is stopped. If you are taking norethisterone once your period has started, it may not work.

Can norethisterone stop a period once is has started?

No, norethisterone cannot stop your period once it has started. If you take norethisterone on the day of your period, or anytime during your period, is it not likely to work as this is too late. Unfortunately, there are no pills to stop menstruation immediately.

You can try taking the contraceptive pill on the first day of your period to help to shorten the length of your period, but it will not stop your period completely.

When will my period start again?

Your period will start around 2-3 days after stopping norethisterone

What if I don’t get a period?

If you do not get a period within a few days of stopping treatment, you should do a pregnancy test. Not getting a period after taking norethisterone does not necessarily mean you are pregnant. Sometimes periods can take a few days longer to start, however, a pregnancy should be done for precaution.

Does norethisterone reset your cycle?

Yes, norethisterone will change the date of your cycle. When you take norethisterone, it delays your period. Once you stop taking the tablets, you will get a bleed after a few days, which will reset your cycle. The date your period restarts is your new cycle date. You can expect your next period approximately 28 days after your period starts, assuming you have a 28 day cycle.

What to do if norethisterone is not working

Norethisterone has a high success rate and is effective in delaying menstruation. If it has not worked, this may be because you have not started treatment on time, or you may have missed doses. In cases where the correct protocol has been followed, you should contact your GP or pharmacist for advice.

Is norethisterone a contraceptive?

Norethisterone is a contraceptive when used at a different strength. The dose of norethisterone tablets required to delay periods will not prevent you from getting pregnant. There is a chance that you can ovulate when taking norethisterone, so you should practice contraception if you do not wish to get pregnant. You may wish to consider a combined oral contraceptive pill and miss out the tablet-free interval if you wish to benefit from contraception.

What is the difference between norethisterone and Utovlan?

Utovlan is the branded versions of norethisterone. They contain the same active ingredient (norethisterone), and the only difference may be in the inactive ingredients (such as excipients that bind the tablet together). They all work in the same way and are equally as effective. Some women may have tried a brand and may want to stick with that, but no particular brand is better than the other. If you would prefer a brand, please get in touch and we will try our best to accommodate. 

Can you get norethisterone tablets on the NHS?

Norethisterone is available on the NHS to delay periods, although this is at the discretion of your GP. It is also available on the NHS to treat endometriosis and heavy or painful periods.

Can you buy norethisterone tablets over the counter?

Norethisterone tablets are not available to buy over the counter. You will need a prescription in order to purchase treatment.

Is it dangerous to delay your period?

How can I stop my period?

Norethisterone tablets can be taken for a maximum of 20 days, giving 17 days period free (as it needs to be taken three days before the onset of a period).

Most women find that norethisterone is effective at delaying their period. Some women may find that they experience occasional spotting (small spots of blood that are visible on underwear), or light breakthrough bleeds. Taking norethisterone tablets closer to the time of your expected period can increase the chances of this happening. It is important to try and take norethisterone three days before your expected period to reduce the chances of spotting. If you take norethisterone too late, it will reduce the chances of it working to stop your period.

Norethisterone cannot be taken with the contraceptive pill. If you are taking the progestogen only pill, also known as the mini pill, there is no need to take a period delay tablet if you are not having a bleed. If you do experience bleeding, you should stop taking the mini pill before using norethisterone.

If you are taking a combined contraceptive pill, you can avoid having a period by taking two packets back to back (missing out the tablet free days). You can take up to three packets back to back. This is common practice and works for 21-day monophasic pills such as MicrogynonYasminRigevidon and Cilest. It is important to seek advice from a healthcare professional before doing so.

If you are taking a 21-day phasic pill such as Logynon or Binovium, you should consult your GP or pharmacist. This is because each pill contains a different number of hormones and need to be taken in the correct order to be effective. 

Norethisterone tablets are an effective way in delaying periods. You should always check with your doctor beforehand to see if it is suitable for you to take these tablets, as it can be dangerous for some women (e.g. women with a personal or family history of blood clots).
