Utovlan, known generically as norethisterone, is a synthetic form of the female hormone progesterone. It is primarily used in the management of menstrual disorders such as heavy periods, painful periods, irregular periods, or premenstrual syndrome (PMS). Additionally, Utovlan can be prescribed to delay menstruation for special circumstances, such as vacations or sporting events. It works by mimicking the actions of natural progesterone, which is essential for regulating the menstrual cycle and maintaining the lining of the uterus. By doing so, Utovlan effectively alters the uterine lining, making it less suitable for a fertilized egg to implant and also helps in reducing menstrual bleeding and discomfort. It is important to follow the prescribing doctor's instructions when taking Utovlan to ensure its effectiveness and minimize potential side effects.
