Aygestin (Norethisterone) – What It Is, Uses, Dosage, Interactions, and Side Effects
Many women use Aygestin (Norethisterone) to treat several conditions related to abnormal uterine bleeding and other conditions caused by hormonal imbalance. These conditions usually affect mature women due to change in their body hormones as they become older. The changes are usually characterized by several symptoms which include excessive bleeding, irregular periods, and other symptoms. Allowing the condition to carryon for a prolonged period is risky since it may lead to irreversible damage to the uterus or excessive loss of blood and this is the reason women are advised to seek medical help as soon as they detect the symptoms however mild they may be.
A Brief on Norethisterone/ Aygestin

Norethisterone, an acetate ester is indicated for use in stopping abnormal bleedings in the uterus and other related conditions such as endometriosis and amenorrhea.
How Norethindrone Acetate Works
Norethindrone acetate which comes in form of a tablet is a synthetic progestin that seeks to help cure abnormal uterine bleeding and other issues caused by hormone imbalance in women. It contains the same chemical compounds found in Progestine steroids and helps in stopping the production of gonadotropin by the pituitary gland. Its working is similar to that of progesterone which prevents women from ovulating. Progestin is steroid hormones that have the same effect as progesterone. Norethindrone works by stopping gonadotropin production from the pituitary gland, leading to prevention of ovulation in females. Unusual bleeding (either too much, too little, or prolonged bleeding) happens when the hormones get out of balance. Norethindrone Acetate seeks to restore the hormonal imbalance.
