Medication features
Norethisterone is an artificial version of a hormone that behaves like the naturally occurring hormone progesterone. It is used to delay a woman’s period for up to 17 days if necessary. Norethisterone tablets are not a form of contraception, so a woman must continue to take precautions. It is safe to use whilst a woman is taking the mini-pill; however, it isn’t safe whilst using a combined contraceptive pill.

Overview
What is Norethisterone?
Norethisterone is a prescription medicine that can delay menstruation for up to 17 days. It can be prescribed to anybody who has a period and wants to delay it for a reason - the reason does not have to be medical, but a doctor does need to clear it.
Norethisterone is a hormone that keeps progesterone levels high. This elevation in progesterone levels means that menstruation is unable to start like it normally would. When taken correctly, Utovlan also prevents all period symptoms, such as cramps, mood swings, nausea, and headaches.
Some people take Norethisterone for other reasons, including dealing with heavy or painful periods, irregular periods, endometriosis, or breast cancer.
If taken for periods, Norethisterone should only be a temporary solution. If your periods are too difficult to deal with, it’s important to speak to a doctor about other treatments.
How do period delay tablets work?
Norethisterone (Utovlan), a synthetic progesterone hormone, can manipulate your body into delaying your period. This medication is able to delay your period because it causes the womb to hold on to the womb lining for longer, by working in the same way as your body's natural supply of progestogen. This occurs because Norethisterone has the ability to stimulate the womb lining, so that it keeps on growing for as long as you take it.
Utovlan or Norethisterone?
Norethisterone and Utovlan are the same thing. Both cause the same effect (delaying your period) using the same drug. Utovlan is simply the brand name of Norethisterone.
Norethisterone is the drug that is present in Utovlan and other period delay medication.
Is Norethisterone safe?
Norethisterone is generally safe for most people who take it occasionally. However, the dose should not be exceeded, and it should not be taken for longer than 17 days.
Norethisterone can cause some side effects, and it is not suitable for some people with certain conditions or those that take specific medications (please refer to side effects drop down for more information about these conditions and types of medication). This is why it is important to always consult a medical professional before embarking on a course of Utovlan or any medication.
Can Norethisterone stop your period once it’s started?
No, Norethisterone cannot stop your period once it has already started. For full effectiveness, the course of Norethisterone should be started three days before your period. Please see the patient leaflet for further information.
Does Norethisterone stop you from getting pregnant?
Norethisterone is not a form of contraception, and women who take it should also use a form of contraception, such as condoms, to stop getting pregnant. All Utovlan does is prevent your womb lining from shedding, meaning that it is still possible to get pregnant while taking this tablet.
Norethisterone reviews
Norethisterone reviews are generally very positive. Most people try Norethisterone for occasions when they don’t want to experience their period - such as a holiday, a wedding, or a spa day.
Most people who have tried them reported that they worked well to delay their period, and it arrived within 2-3 days afterwards ceasing to take the medication.
Some reviewers did report a few cramps after their course of Norethisterone, which may be a more common side effect. However, most Utovlan reviews reported little or very mild side effects and note that the tablets work as stated.
Of course, as with any medication, different people can react very differently to Norethisterone. Therefore, it’s important to recognise the side effects and be prepared for them, even though the chance of them occurring is minimal.
Directions
How do I use period delay tablets?
If you are taking norethisterone to delay your period, there are a few things you should know. Firstly, it's important you can predict when your period is due. As long as this is known, you should start taking norethisterone three days before your period is due to start. One 5mg tablet is taken THREE times daily. When you want your period to start, simply stop taking the medication. After stopping, your period should start 1-2 days later.
