Ethione CR 15 Tablet contains Norethisterone 15mg, a synthetic progestogen used primarily to manage menstrual disorders and hormonal imbalances in women. It is commonly prescribed for conditions such as irregular menstruation, heavy menstrual bleeding, secondary amenorrhea, and endometriosis. Norethisterone works by mimicking the natural hormone progesterone, regulating the menstrual cycle and preventing the lining of the uterus from thickening excessively. This helps in controlling abnormal bleeding and alleviating symptoms associated with hormonal fluctuations. Ethione CR 15 is also utilized to delay menstruation for personal or medical reasons. The controlled-release formulation ensures a steady release of the active ingredient, providing prolonged therapeutic effects and improving patient compliance by reducing the frequency of dosing. Patients should take this medication exactly as prescribed by their healthcare provider, typically starting a few days before the expected onset of menstruation. Common side effects may include nausea, headache, breast tenderness, and mood changes, but serious adverse reactions are rare. It is important to inform the doctor of any existing medical conditions, such as liver disease, blood clotting disorders, or hormone-sensitive cancers, before starting Ethione CR 15. Regular follow-up is advised to monitor treatment efficacy and safety.
