What is the mechanism of action of Norethisterone?
Norethisterone is a synthetic form of progesterone, a female sex hormone. It works by simulating the effects of progesterone in your body.
Throughout your monthly menstrual cycle, your progesterone levels normally fluctuate. Your uterine lining thrives as progesterone levels rise, preparing to receive a fertilised egg.
If you do not become pregnant, your hormone levels drop, leading your uterine lining to shed as a period. If you do become pregnant, keep your progesterone levels high to help keep your uterine lining healthy throughout the pregnancy.
Is it possible to stop your period with Norethisterone?
The growth and shedding of the uterine lining can be manipulated or regulated by taking Norethisterone at specific stages during this cycle.
Taking Norethisterone a few days before your period is due, for example, will fool your body into believing you're pregnant, and you won't have a period until you stop taking it.
If you take Norethisterone a few days before your period, your body will believe you're pregnant.
Taking Norethisterone every day if you have endometriosis provides the same effect and prevents the abnormal tissue from changing monthly.
During treatment, your periods are likely to stop, and patches of endometrial tissue may shrink after you stop taking Norethisterone.
