thanks for the query,
tablets belong to a group of medicines called progesterones. These work by acting on receptors in the body to mimic or exaggerate the effects of the natural hormone, progesterone.
Norethisterone tablets may be used to treat:
1) or prevent abnormal or unexpected bleeding from the uterus
2) the symptoms of pre-menstrual syndrome which occur before a period including breast pain
, headache, migraine
, water retention and mood swings .
3) painful or heavy menses.
4)the tablets can also be used to stop periods,
but it is not advisable for a long term use as they can cause hormonal
disturbances, so I would suggest you go for a homeopathic
treatment to regularise your period.
wishing you good health and best wishes
