# NORETHISTERONE 5 MG ## SHORT DESCRIPTION **Norethisterone 5 mg** is a synthetic **progestogen (progestin)** medicine that mimics some of the effects of the natural hormone progesterone. It is used for several menstrual and gynecological conditions, including **heavy or painful periods, irregular menstrual bleeding, endometriosis**, and in some circumstances to **delay menstruation**. Norethisterone is a prescription hormonal medicine and should be used according to the indication and dosing schedule prescribed by a healthcare professional. --- ## KEY BENEFITS * Helps control **heavy menstrual bleeding**. * May reduce **painful or irregular periods**. * Can be prescribed to help manage **endometriosis-related symptoms**. * May help regulate abnormal uterine bleeding in appropriate patients. * Can be used for **short-term postponement of menstruation** when medically appropriate. * Provides progestogenic hormonal activity to help control the menstrual cycle. --- ## USES / INDICATIONS Norethisterone 5 mg may be prescribed for: 1. **Heavy menstrual bleeding (menorrhagia)**. 2. **Painful periods (dysmenorrhea)**. 3. **Irregular or dysfunctional uterine bleeding**. 4. **Endometriosis**. 5. **Premenstrual symptoms** in selected patients. 6. **Menstrual period postponement/delay** for specific short-term situations. 7.
