Does taking medicine in early pregnancy affect the fetus?

Pregnancy is a very happy thing for women. However, sometimes due to physical reasons, some diseases will occur during pregnancy, and they will take some relief medicines appropriately. So, will taking medicines in the early pregnancy have any effect on the fetus? Will it affect the development of the fetus? How much harm will the medicines do to the fetus? Can you take medicines in the early pregnancy? Let me give you a detailed introduction below.

Taking medications in early pregnancy can have a significant impact on fetal development. The probability and extent of the impact are related to factors such as the type of medication, dosage, duration, and physical condition of the pregnant woman. If you want to keep the fetus, it is recommended to do prenatal checkups (such as Down syndrome screening at 14-20 weeks of pregnancy and color Doppler ultrasound fetal abnormality screening at 22-26 weeks of pregnancy), and deal with any abnormalities in a timely manner.

The doctor will choose the medicine for you when he knows that you may be pregnant. This should be based on your specific situation. In addition, judging from the time you take the medicine, it should have no effect on the embryo. Generally speaking, from the 18th day after fertilization, that is, within 33 days of menopause, there is almost no teratogenic effect of the medicine.

If it is 3 weeks to 3 months after fertilization, that is, about 33 days to 13 weeks after menstruation, this period of time is the sensitive period of fetal teratogenicity, and congenital malformations are most likely to occur.

During the 3rd to 5th week of pregnancy, teratogenic drugs can cause malformations of organs or systems such as the central nervous system, heart, intestines, skeletal muscles, and muscles; during the 34th to 39th day of pregnancy, they can cause limbless fetuses; during the 43rd to 47th day of pregnancy, they can cause fetal hypoplasia and anorectal stenosis. The final stage of fetal development is from the third month of pregnancy to full term, during which malformations of the central nervous system or reproductive system may occur.

In the early stages of pregnancy, you must pay attention to the health of the fetus. Many western medicines will have some side effects. If you take too much, it will definitely cause malformations. Therefore, when you need to take medicine, you must follow the doctor's advice and not take medicine at will, especially during the dangerous period of pregnancy, which can easily cause miscarriage or fetal malformations.
