After 3 weeks of pregnancy, some drugs can enter the fetus through the placenta. This is a critical period for the development of fetal tissues and embryonic organs, and it is also a period when the fetus is highly sensitive to drugs. Improper use of medication can lead to various malformations in the fetus. Although medication in the second and third trimesters rarely causes fetal organ malformations, it may also cause organ dysfunction after birth. So, as a mother, you need to understand this.
The principles of medication before and during pregnancy are:
1. Women who plan to become pregnant and women of childbearing age who do not take contraceptive measures should consider the possibility of pregnancy after menstruation. If you feel unwell at this time, you should use it with caution.
2. Generally speaking, the earlier the medication is taken, the longer the medication is taken, and the higher the dose, the greater the impact on the fetus. In principle, minimal or no medication should be used during early pregnancy.
3. When medication is needed for various reasons, drugs that have no or little impact on the fetus should be selected under the guidance of a doctor. One kind of medicine can solve the problem. Never choose multiple medicines; use more Chinese medicine and less Western medicine.
4. If there are serious complications, they will be life-threatening if not treated in time, so you cannot take one into consideration and lose the other. Even if a drug is harmful to the fetus, the pros and cons should be weighed under the guidance of a doctor, and the drug should be used rationally before considering whether to terminate the pregnancy.
