General information

Generic Aygestin (Norethisteron) is a progestin. It causes the transformation of the uterine mucosa from the proliferation phase to the secretory one, and after conception, the necessary conditions are created for the implantation of the impregnated ovum. The drug deminishes the excitability and the number of muscles of the uterus, induces the development of the terminal elements of the mammary gland. Suppresses the secretion of gonadotropins by the pituitary gland, averting the maturation of follicles and ovulation.

On admission, Norethisteron binds to progesterone receptors in end-organs, including myometrium. Norethisteron in the cytoplasm of cells forms a complex with specific receptors that binds to the chromatin of target cells and alters the synthesis processes in them. Norethisteron blocks the secretion of gonadotropin in the pituitary gland, thus hindering the onset of ovulation and the maturation of follicles, transforms the uterine mucosa from the proliferation phase to the secretory phase. Norethisteron slows down proliferous activity in the hyperplastic endometrium. Norethisteron contrib utes to the secretory transformation, the development of atrophic changes in the stroma and epithelium of the glands and the decidual reaction of the stroma. After fertilization, Norethisteron promotes the transition of the tunica mucosa of the uterus to a state that is favorable for the growth of a fertilized egg.

After 2 to 4 days after discontinuation of Norethisteron, menstrual-like bleeding occurs. Due to the effects on the endometrium, Norethisteron leads to the cessation of dysfunctional bleeding. Norethisteron stimulates the development of the terminal elements of the breast. Norethisteron has mild androgenic and estrogenic properties.

If the indicated bleedings are persistent, then it is necessary to exclude their organic cause.

Alcohol interaction

To answer the question about the compatibility of hormonal drugs and alcoholic beverages, you need to know why this or that medication is used.

Norethisteron is prescribed in the treatment of infertility. That is, the woman is trying to get pregnant, so drinking alcohol during the preparation for conception, at least, is unwise.

Although Norethisteron itself does not interact with ethyl alcohol, it can negate all medical appointments. And alcohol is not needed for a woman who is trying to have a baby.
Norethisteron tablets are used for the growth of the inner layer of the uterus — endometriosis. The disease is accompanied by pain and bleeding. Alcohol dilates blood vessels and can provoke an unpleasant relapse.

What is the danger of Norethisteron? The drug has a negative effect on the liver, so it is not prescribed to patients with hepatitis, even if the disease is completely cured. The liver works to wear for the processing of alcohol.

Aygestin Reviews

Tanya (28): After giving birth to my baby, I was disturbed by extremely heavy menstruation. The examination (ultrasound intravaginal) showed the presence of a polyp in the uterus and endometrial change in the type of endometriosis. It is necessary to do hysteroscopy and remove all these defects. But before the invasive treatment, my doctor decided to try the pills. The gynecologist prescribed Generic Aygestin, a course on certain days of the cycle, for three months. I took 2 pills a day regardless of food intake, also I tried to take them at a fixed time (for example, the first pill in the morning at 10 o'clock, the second in the evening at 22 o'clock). I have been taking them for 2 months already, now there is a third course. The impressions from the reception are great! Menstruation became less profuse after the first month of admission and painless. Moreover, there is no fluid retention before menstruation.

Susanna (33): The drug causes a wild appetite. As an average woman in the last days of the cycle, I always want a chocolate with herring, and a salty cucumber. When I am taking Norethisteron, the appetite increases significantly. I always want to eat.

Bojana (35): I am a balanced and calm woman. 5-7 days before the onset of menstruation, I get a little more emotional, I can cry. If I’m taking Generic Aygestin, I am annoyed, I am not happy about the surrounding people, they get angry. Maybe I exaggerate a little, but only a little. The storm calms down the day after the end of the last pill.
