Aygestin

Generic Name: Norethindrone acetate

  • What is Aygestin?

    Aygestin contains a type of hormone known as progesterone. It is used to restore menstruation in women who have stopped having menstrual cycles (also called amenorrhea). Aygestin can also help treat endometriosis, a condition where the endometrium (the lining of the uterus) doesn't shed properly and attaches to the outside of the uterus or other areas such as the ovaries or bowels. Aygestin also helps control unusual and heavy bleeding of the uterus caused by hormonal imbalance. However, the drug is not used to control bleeding caused by fibroids or cancer.
