Ethione CR 10 Tablet contains Norethisterone 10mg, a synthetic progestogen used primarily for managing menstrual disorders and regulating menstrual cycles. It is commonly prescribed to treat conditions such as irregular menstruation, heavy menstrual bleeding, secondary amenorrhea, and endometriosis. Norethisterone works by mimicking the natural hormone progesterone, helping to restore hormonal balance and control the growth of the uterine lining. This medication is also utilized to delay menstruation for personal or medical reasons. Ethione CR 10 Tablet is formulated as a controlled-release tablet, ensuring a steady release of the active ingredient over time for improved efficacy and reduced side effects. Patients should take the tablet exactly as prescribed by their healthcare provider, typically starting a few days before the expected menstrual period or as directed for specific conditions. Common side effects may include nausea, headache, breast tenderness, and mood changes, but serious adverse effects are rare when used appropriately. It is important to inform the doctor of any existing medical conditions, allergies, or concurrent medications to avoid potential interactions. Ethione CR 10 Tablet should not be used during pregnancy or by individuals with a history of thromboembolic disorders without medical supervision.
