Does Norethisterone stop periods?
Norethisterone is a class of drugs that can delay periods. It does so by mimicking the female sex hormone progesterone. The role of progesterone is to keep the lining of the womb healthy and ready for a fertilised egg. This rises in your cycle just before optimal fertility each month. If the womb receives a fertilised egg progesterone stays high in your system, if it doesn’t receive a fertilised egg then progesterone decreases. Taking Norethisterone at various points in your cycle can regulate the growth and shedding of the womb lining by tricking the body into thinking you’re pregnant. Therefore, this delays the shedding of the lining.
