Noteron 5 mg is a synthetic progestogen medication, primarily used to treat menstrual disorders such as heavy or irregular bleeding, and to manage conditions like premenstrual syndrome (PMS) and endometriosis. It works by mimicking the natural hormone progesterone, helping to regulate the menstrual cycle and prevent excessive uterine bleeding. In addition, Noteron can be used to delay menstruation for specific purposes. The typical dosage depends on the condition being treated, and it is generally taken orally. Common side effects may include irregular bleeding, nausea, headaches, or breast tenderness, though these are usually temporary. It is important to use Noteron under medical supervision to ensure its suitability and minimize potential risks, particularly for individuals with a history of hormone-sensitive conditions.
