What is Norethisterone
Norethisterone is designed to give you more control over menstruation. It is a hormonal medication which contains a form of progesterone which allows you to delay your period for up to 17 days. The drug can also be used to help prevent or lessen the effects of a range of menstrual cycle disorders including pain or abnormally heavy bleeding, and it can be used in the treatment of menopausal syndrome and breast cancer.
How does Norethisterone work?
Norethisterone acts on receptors in the body with the purpose of exaggerating or mimicking the effects of the natural hormone progesterone. When taken to delay periods, it causes the womb lining to be sustained until the treatment is interrupted or stopped.
It is important to note that the drug is not a contraceptive, so if you are sexually active and do not want to get pregnant, alternative methods of contraception must be used.
What are the side effects of Norethisterone?
As with any medication, there can be side effects to consider which vary in severity. Side effects associated with Norethisterone include headaches, dizziness, rashes, itching, nausea, acne, libido changes and depression. If you would like further details on the possible symptoms, don’t hesitate to get in touch by email or phone. Our experts will be on hand to answer any queries you may have.
Why choose Norethisterone?
This medication offers a safe and effective way to delay periods for women who do not take the contraceptive pill, and it has a range of other uses too. You can take it to:
- Delay or stop your periods for a while
- Have easier and more regulated menstrual cycles
- Lessen the effects of the menopausal syndrome

How should I take Norethisterone?
When using Norethisterone to delay menstruation, you will need to start treatment three days before your period is due, ingesting one pill three times a day. You can take it for up to 17 days and menstruation should start two to three days after you stop having the tablets. If you are using the medication for another purpose, seek advice from your doctor or our specialists.
What dose should I choose?
The dosage you need to take will depend on your reason for using the treatment. To delay your period as a one-off you should take one 5mg pill three times a day starting at least 3 days prior to your period due date. Detailed instructions are provided with the medication and you can get more information from your doctor or by contacting our expert team at Click Pharmacy.
How long can I take Norethisterone for?

The 7 day delay pack contains 30 tablets and the 17 day delay pack contains 60 so the choice is yours based on how long you want to remain period free for and the reason behind you taking it.
Alternatively, if you are prescribed Norethisterone for:
- premenstrual tension - you will usually take a 5mg tablet for 10 days starting 16 days after your last period.
- endometriosis - you will usually take one 15mg tablet 3 times a day for a minimum of 6 months and if you experience irregular bleeding or spotting during this time your GP may increase this to 4 or 5 tablets of 20-25mg.
- breast cancer - you will usually be prescribed 8 40g tablets a day increasing to 12 60mg tablets if necessary.

If you are pregnant the hormone could cause damage to the development of the baby. As such it is important to do a test prior to taking the medication if there is a chance you could be
If you are diabetic then you must inform a GP or doctor at Click Pharmacy of this fact as Norethisterone can affect your metabolism leading to an alteration of blood sugar levels and increased levels of insulin between meals.
Due to the reasons outlined above, it is very important to inform your medical professional if any of them apply to your situation so that they can safely prescribe this medication to you or help you find one that is appropriate.
