How does Norethisterone work?

The active ingredient in Period Delay tablets supplied by PrivateDoc is Norethisterone. Norethisterone belongs to a group of medicines called progestogens which are female sex hormones. These medicines work by mimicking the effects of female sex hormones produced in the body.

Norethisterone is not a method of contraception and will therefore not prevent pregnancy, so you should continue to use contraceptive methods.
