Norethisterone is an unbranded medication that contains the active ingredient norethisterone. This is a type of medication known as a progestogen and it works very similarly to the natural hormone in your body called progesterone. It can be used to delay your period,which can be helpful if you have an important exam or are going on holiday.
Norethisterone can also be found under the branded name Utovlan. Asda Online Doctor has both norethisterone and Utovlan.
Norethisterone contains a progestogen, which works very similarly to the female hormone progesterone. Usually, during your menstrual cycle, your progesterone levels drop when you are due to start your period. This causes the lining of your womb to shed, which causes bleeding. When you take norethisterone tablets before your period it replaces your natural progesterone, meaning your period will be delayed until you stop taking it.
Norethisterone cannot be taken if you are also on the combined oral contraceptive pill. In this case, the combined contraceptive pill can be used to delay your period instead. Norethisterone should not be taken if you have a history of blood clots.
When taking norethisterone tablets to delay your period, you should start taking it 3 days before your period. It can be helpful to keep a diary or use a menstrual calculator to work out when your next period is due. Norethisterone 5mg tablets should be taken 3 times a day, at regular intervals, for a total daily dose of 15mg. When your treatment is finished, your period should start after 2 to 3 days.
If you forget your norethisterone tablets, take your medication as soon as you remember. You can then carry on as normal but you should not take a double dose to make up for a missed dose.
Most women can safely take norethisterone. You should not take norethisterone if you are using the combined oral contraceptive pill. Norethisterone can increase your risk of blood clots, so you should not use this if you have a higher risk of blood clots. You might have a higher risk of blood clots if you have a family or personal history of blood clots, or if you smoke and are overweight or are over 35 years of age. If you have a history of high blood pressure or some other health conditions you might not be able to use norethisterone.
Our doctors will make sure norethisterone is suitable for you before prescribing it. There are some medications or medical conditions that may make norethisterone unsuitable or less effective in delaying your period. We have other period delay treatments available if norethisterone is not suitable.
Norethisterone can be taken by women looking to delay their period for up to 17 days. Like all medications, norethisterone can have some side effects.

Provera contains the active ingredient medroxyprogesterone acetate, which is also a progestogen. This works like norethisterone to delay your period by acting like progesterone in your body. It can be prescribed to delay your period and is suitable if you have a history of blood clots.
If you take the combined oral contraceptive pill, this can be used to delay your periods by taking it back to back. The combined oral contraceptive pill can delay your period for a month until your next break between packs. You might notice some light bleeding or spotting if you take your pill back to back for more than 2 months in a row. You cannot delay your period with the progesterone only contraceptive pill.
