Treatment of menstrual disorders such as abnormal uterine bleeding (AUB)/dysfunctional uterine bleeding, heavy menstrual bleeding, irregular periods; secondary amenorrhoea (absence of periods); postponement of menstruation; endometriosis (as prescribed).

Norethisterone is a synthetic progestin (progesterone-like hormone). It stabilizes the endometrium (uterine lining) and reduces abnormal shedding/bleeding. When stopped after a course, withdrawal bleeding usually occurs.

Oral tablet. Take exactly as prescribed by the doctor; swallow whole (do not crush/chew) as it is controlled release. Can be taken with or without food, preferably at the same time each day. Dose and duration depend on the condition (e.g., bleeding control, period delay, endometriosis).
