Norethindrone or Norethisterone is a progestin, containing a type of
female hormone known as progesterone. Norethindrone acetate has
various functions and depending on the brand or dosage prescribed,
can be used for several different purposes or menstrual disorders, such as:
birth control (contraception), to treat menstrual disorders like endometriosis.
To treat abnormal vaginal bleeding caused by hormone imbalance, to treat
an irregular menstrual cycle or lack of menstrual periods (amenorrhea) to restore menstruation.
Norethindrone is sometimes used to advance or delay periods (menstruation) if required by
personal circumstances and also in IVF treatment (in-vitro fertilization) where norethisterone
controls the timing of the preceding menstrual cycle and therefore the timing of the IVF cycle.
