What are the effects of medications on early pregnancy?

Medicines are very important things in people's lives. People's diseases often need to be solved by taking medicines, but not everyone is suitable for taking medicines. For example, pregnant people need to be careful when taking medicines, because many medicines are toxic and will harm the development of the fetus. Let's take a look at the effects of medicines on early pregnancy. I hope everyone can understand.

According to statistics, 35-46% of expectant mothers need medication (excluding vitamins and calcium supplements) during pregnancy. The main reasons are common diseases such as colds, gastroenteritis, or pre-existing diabetes. Diseases such as hypertension require continued treatment, or diseases specific to pregnancy such as pregnancy-induced hypertension syndrome occur.

Early pregnancy is considered a sensitive period for the teratogenic effects of drugs. Generally speaking, if the medication is taken within 4 weeks of pregnancy, the effect on the fetus is all or nothing. If the embryo does not miscarry, it indicates that the medication is unlikely to affect the embryo. Secondly, there is currently no prenatal diagnostic technology that can clearly diagnose the effects of medication during pregnancy on the fetus. 1 to 2 weeks after fertilization: The effect of drugs on the embryo is "all or nothing", that is, either there is no effect or there is an effect leading to miscarriage. It generally does not cause fetal malformations. Therefore, when you take drugs before pregnancy or in early pregnancy when you don't know whether you are pregnant, it generally will not have much effect on the fetus. You don't need to worry too much or have an abortion.

3 to 8 weeks after fertilization (i.e. 5 to 10 weeks after menopause): This is called the teratogenic sensitive period. It is the period when the embryonic organs are differentiated and formed. They are very susceptible to external factors such as drugs and can cause fetal malformations. During this period, no medication is needed, including general health products and tonics. If you must take medication, be sure to use it carefully and safely under the guidance of a doctor. If there is a history of medication, prenatal diagnosis (including B-ultrasound) can be performed between 16 and 20 weeks of pregnancy to further understand the growth and development of the fetus and rule out fetal malformations.
