What is Norethisterone?

Norethisterone is a synthetic progestin - a man-made hormone similar to progesterone.

It is used to treat heavy or painful periods, premenstrual syndrome (PMS), endometriosis, and to delay your period for special occasions and holidays.

Buy Norethisterone Online in UK

Norethisterone is only available on prescription and cannot be bought over the counter. However, you can buy Norethisterone online following an online consultation.

All you need to do is fill in our online medical form for our clinician to assess if Norethisterone is suitable for you.

How does Norethisterone work?

During the menstrual cycle, the level of progesterone hormone in the body changes, affecting the lining of the uterus. When progesterone levels are high, the lining of the uterus is thick to allow an egg to plant itself and get ready for fertilisation. If the egg is not fertilised, the progesterone level falls again, and the lining of the uterus and the egg cell is shed during a menstrual period (bleeding).

Norethisterone keeps the levels of progesterone high, tricking the body into thinking it is pregnant. As a result, the uterine lining is not shed, so a regular period bleed does not occur.

It can be safely prescribed to women between 18 and 54. Suppose you are outside this limit or are taking a combined contraceptive pill. In that case, we suggest contacting your doctor as there may be alternatives better suited for you to delay your period.

Norethisterone is not a form of contraception and will not protect you against unwanted pregnancy. You should use another form of contraception, such as condoms, while taking Norethisterone.

How do I take Norethisterone?

You should start taking Norethisterone 3 days before your period is due to start for maximum effectiveness.

The usual dosage is one pill three times a day.

Swallow the tablets whole with a glass of water.

Norethisterone tablets can be taken with or without food.

Our doctors can prescribe a maximum of 42 tablets, which can delay your period for up to 14 days.

Your normal period should resume 2-3 days after taking the last tablet. If your period does not start after this time, don't hesitate to contact our clinicians or your regular GP for further advice and assistance.

Do not take Norethisterone if you are pregnant.

What should I do if I forget to take Norethisterone?

If you forget to take Norethisterone when you should, take it as soon as you remember. Continue to take Norethisterone at the usual time.

Do not take more Norethisterone to make up for the dose you missed.

What should I do if I take more Norethisterone than I should?

If you take more Norethisterone tablets than you should, speak to your doctor straight away.

Norethisterone side effects and cautions

Norethisterone is not suitable for all women. If you are unsure whether Norethisterone is suitable for you, speak to your doctor.
