    Norethisterone is an artificial version of a hormone that behaves like the naturally occurring hormone progesterone. It is used to delay a woman’s period for up to 17 days if necessary. Norethisterone tablets are not a form of contraception, so a woman must continue to take precautions. It is safe to use whilst a woman is taking the mini-pill; however, it isn’t safe whilst using a combined contraceptive pill.

Norethisterone, sold under the brand name Utovlan, is a synthetic version of the hormone progesterone, used to regulate periods. Norethisterone acts as a supplement to progesterone, keeping levels high so that the uterine wall does not shed as it does in a usual period, and will so prevent a usual period bleeding period.
