Prophylaxis against recurrence of dysfunctional bleeding: If there are no signs of resumption of normal ovarian function recurrence must be anticipated. Cyclical bleeding can be established with 1 tablet twice daily from the 19th to the 26th day of the cycle. Premenstrual syndrome (including premenstrual mastalgia): 2-3 tablets daily from the 19th to the 26th day of the cycle. Treatment should be repeated for several cycles. Postponement of menstruation: 1 tablet three times daily, starting 3 days before the expected onset of menstruation. A normal period should occur 2-3 days after the patient has stopped taking tablets. Endometriosis (pseudo-pregnancy therapy): Long-term treatment is commenced on the 5th day of the cycle with 2 tablets daily for the first few weeks. In the event of spotting, the dosage is increased to 4, and, if necessary, 5 tablets daily. After bleeding has ceased, the initial dose is usually sufficient.

Drug Mode of Action ::  

Norethisterone has typical effects of a progestogen and converts the endometrium from the proliferative to the secretory phase. It may also have some oestrogenic, anabolic and androgenic activities, but these may not be significant. Norethisterone delays onset of periods and controls abnormal uterine bleeding. It also has contraceptive effects due to negative feedback inhibition of pituitary gonadotropin thus preventing ovulation.

Drug Interactions ::

Concentration may be reduced by CYP450 inducers (e.g. phenobarbital, phenytoin, carbamazepine, rifampicin, rifabutin, nevirapine, efavirenz, tetracyclines, ampicillin, oxacillin, co-trimoxazole) and ritonavir, nelfinavir (usually inhibitors of CYP450 but have inducing properties when used with steroid hormones). May cause additive fluid retention with NSAIDs, vasodilators. Adjustment in antidiabetic, thyroid hormone and anticoagulant therapy may be required. Potentially Fatal: May increase ciclosporin concentration.
