Regestrone Tablet is a medication containing norethisterone, a synthetic form of the naturally occurring female sex hormone progesterone. It is prescribed for various menstrual and gynecological issues, including heavy periods, irregular cycles, and the management of conditions like endometriosis. By acting on the uterine lining, it helps to restore hormonal balance and regulate the menstrual cycle. The specific use and duration of treatment depend heavily on the medical condition being addressed, and it is crucial to follow a doctor's guidance.

Core Medical Applications of Regestrone

Regulation of Menstrual Cycles

Regestrone is commonly used to treat irregularities in the menstrual cycle, such as amenorrhea (the absence of periods) and menorrhagia (heavy menstrual bleeding). It helps reduce bleeding by controlling uterine lining growth and shedding, and can induce a normal cycle in amenorrhea cases.

Management of Endometriosis

Endometriosis, characterized by endometrial tissue growth outside the uterus causing pain and irregular bleeding, can be managed with Regestrone. The medication suppresses this tissue growth, relieving symptoms, and treatment often lasts several months.

Treatment of Premenstrual Syndrome (PMS)

For severe PMS symptoms, Regestrone can be prescribed to balance hormone levels and reduce the severity of issues like mood swings, bloating, and breast tenderness.

Delaying Menstruation

Under medical supervision, Regestrone can temporarily delay a period by maintaining elevated progesterone levels, preventing uterine lining shedding. This is not a routine use.

Comparison of Regestrone to other progestins

Regestrone is a synthetic progestin, while natural progesterone and combined oral contraceptives offer alternatives. The choice depends on the specific condition, patient response, and side effects.
