Norethisterone (or norethindrone) (or 19-nor-17α-ethynyltestosterone) is a molecule used in some combined oral contraceptive pills and in some progestogen only pills. It is a progestogen and can be used to treat premenstrual syndrome, painful periods, abnormal heavy bleeding, irregular periods, menopausal syndrome (in combination with oestrogen), or to postpone a period. Norethindrone was the first orally highly active progestin to be synthesized. It was synthesized for the first time by chemists Luis Miramontes, Carl Djerassi, and George Rosenkranz at Syntex in Mexico City in 1951. It was the progestin used in one of the first two oral contraceptives. It is often used as the related ester, norethisterone acetate.

Postponing periods with norethindrone?
Q. Usually i get my periods on the 29th day of my cycle. So, June 16th is my 29th day. But i have got to go to the temple on June 17th(30th day of my cycle). So, i have started having norethindrone tablets today(June 14th). I have been instructed to take 2 tablets per day till the day i want to postpone. When will i get my periods after i stop taking the tablet? Did anyone face any side effects? My main doubt is will i get my next month periods regularly or will it affect the next cycle?

PCOS issues do I have any alternative options?
Q. I either completely skip my periods or bleed nonstop for months until the dr finally gives me norethindrone to stop it. I have problems taking bc has anyone had any alternative treatments for controlling the symptoms

A. Some women with PCOS use Glucophage (a medication used to try and control Diabetic symptoms and a condition called Insulin Resistance) to try and help with controlling some of the symptoms especially if weight is an issue. I am also including the link to a site that may help you find more information. The link is at: (on this site they have messageboards that one can access for even more information)
