What is Norethisterone?
Norethisterone is a synthetic version of the female hormone progesterone that is used to stop your period from coming on time. While Norethisterone is frequently used to delay periods, it has other uses such as treating endometriosis.
It is important to note that while Norethisterone tablets can delay your period, it is not a contraceptive. It is important to use contraceptive methods while taking this medication as it will not prevent pregnancy.
How does Norethisterone work?
Before your period, the level of progesterone in your body decreases. When progesterone falls beneath a certain level, menstruation occurs as a result of the lining in the womb shedding. Norethisterone is a synthetic version of progesterone. Taking Norethisterone thus delays the onset of menstruation in the same way that natural levels of progesterone do. You should have a period 2-3 days after stopping Norethisterone because the decrease of the synthetic hormone in the body causes the lining of the womb to shed.
Norethisterone may not be suitable if you have a history of blood clots.
How do you take Norethisterone?
The typical dosage for Norethisterone is one tablet three times a day starting three days before the expected beginning of the period. Norethisterone tablets should be swallowed with water. Do not take Norethisterone as a form of birth control. Norethisterone does not prevent pregnancy.
How effective is Norethisterone in delaying menstruation?

In order to prevent unwanted pregnancy, please use contraceptive methods while taking this medication.
