Patient's question:
Are there any medications that can delay menstruation by a few days?Doctor's answer:
Hello, menstruation is a regular, cyclical uterine bleeding in women and one of the external signs of reproductive function maturity. This bleeding is the result of the maturation of female follicles, ovulation, and corpus luteum formation, as well as the transformation of the endometrium from proliferation to secretion and its subsequent shedding. This process is achieved by the neuroendocrine system through the production of estrogen and progesterone, so altering any of hormone production will cause changes in the menstrual cycle. In clinical practice, when doctors encounter women with normal menstrual cycles who strongly request a change and fail to be persuaded, they typically use estrogen or progesterone to regulate the menstrual cycle.Methods to delay the onset of menstruation:
1. Take short-acting oral contraceptives starting from the 5th day of the menstrual cycle, taking 2 tablets daily for 2 weeks, then increasing to 4 tablets daily from the 3rd week.
2. Take progesterone-containing medications such as Fuchang tablets (etonogestrel) or Funing tablets (medroxyprogesterone) orally, starting from the 16th day of the menstrual cycle, taking 10 mg daily for continuous oral administration.
3. Take mifepristone, a non-hormonal drug, starting from the 5th day of the menstrual cycle, taking 25 mg daily for continuous oral administration.
Note: Methods 1, 2, and 3 must be taken continuously until the "critical period" is passed, after which they should be discontinued. Menstruation usually occurs within 7 days after stopping the medication.
It is important to note that excessive use of sex hormones may disrupt future menstrual cycles, so these methods should not be used long-term or excessively. If menstrual disorders occur, seek medical attention from a gynecologist promptly.
Additionally, some people may experience side effects such as dizziness, fatigue, nausea, and vomiting when first taking sex hormones, resembling early pregnancy symptoms. Contraindications include: women over 40 years of age, those who are breastfeeding, patients with hypertension, diabetes, liver or kidney diseases, thyroid disorders, thromboembolic diseases, or those with breast or genital organ malignancies or suspected tumors.
In summary, artificially altering the normal menstrual cycle is not advisable, as the disadvantages outweigh the advantages. Doctors do not recommend using these methods in daily life. The above methods should only be used in emergencies and not frequently, to avoid the interference of exogenous hormones in women's normal menstrual cycles, which could lead to serious consequences.
