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

Can I buy Norethisterone 5mg online?

Norethisterone can be purchased in two different pack sizes online via Click Pharmacy. To buy Norethisterone, please arrange a prescription from your GP or book a free and confidential appointment with one of the doctors at Click Pharmacy. They will ask you to fill in a questionnaire which will be used to assess whether this medication is right for you after which you will be prescribed the pack you require.

Our service is quick, easy and discreet and your medication will be with you the next working day.

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.

Some women who experience extremely heavy periods, a medical condition known as Menorrhagia, may be prescribed 10mg tablets to be taken 3 times a day until the bleeding lessens at which point you can go back on to the usual 5mg dosage.

Each time you take a break from the medication, your womb lining will shed as per a normal cycle, but the build-up of progesterone in the system will help to lessen the amount which needs to be released each time your period begins and as such, over time, this is how Norethisterone can support women suffering from extremely heavy periods. There are other ways to ease your heavy periods beside Norethisterone which most GP's will recommend you try first including fitting a coil or taking the contraceptive pill to regulate your menstrual cycle.

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.

How long can I take Norethisterone for?

Norethisterone is not designed to be taken on a regular, monthly basis (unless otherwise prescribed) and as such you will be advised by your GP or the doctor at Click pharmacy to only take the tablets for the prescribed amount of time based on which dosage you buy. 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.
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.

Other warnings to consider

  • Epilepsy
  • Migraine headaches
  • Asthma

  • are unable to move for long periods of time such as post-operation
  • have a history of repeated miscarriage

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.
