People are inevitable when they are sick, and they are no exception during pregnancy.Pregnant women should be particularly careful during pregnancy, especially in the first three months of pregnancy, which is an important period for the formation of baby organs.The effect of drugs on fetuses is related to the period of embryonic development.Take medicine before fertilization and fertilization, which may lead to abnormal chromosomal splitting or mutation and infertility or abortion.2 to 8 weeks after fertilization is the period of organ formation. At this time, taking medicine can cause abortion or malformations of embryos.After nine weeks, enter the fetus. At this time, most organs have been formed. The drug response is not the teratogenic but toxic reaction.
Some expectant mothers are concerned about medication during pregnancy, and they are sick and die.However, the mother and child are in the heart. During the pregnancy, the disease not only makes the mother suffer, but the baby is also uncomfortable in the stomach.I was sick, but how should I take medicine?
If the menstrual period is delayed during pregnancy, be sure to exclude whether to conceive first.After pregnancy, the earlier, the longer the duration, the greater the impact on the fetus.Try to take as little medicine or no medicine in the early pregnancy.If pregnant women are dying, even if the use of medicine is harmful to the fetus, it is necessary to reasonably take medicine and weigh the advantages and disadvantages under the guidance of a doctor, and consider whether to terminate pregnancy if necessary.
There are several ways to categorize drug safety classification during pregnancy during pregnancy. Among them, the standards formulated by the US Food and Drug Administration (FDA) are widely accepted by doctors in various countries.FDA divides the safety of drugs into five categories: A, B, C, D, and X. Some drugs have two different risk levels, one is the level of common dosage, and the other is the ultra -dosage level.The two -level drugs of Class A and B are relatively safe.
1 A level
Women in the first three months of pregnancy show signs of harm to the fetus (and no harmful evidence in the next six months), which has a small impact on the fetus on the fetus.There are very few drugs in class A. Vitamin belongs to such drugs, such as various vitamin B and C, but vitamin A with a normal range is a category A, and a large dose of vitamin A daily dose of 20,000 i U.You can cause teratogenic and become a category X drug.
2 B level
In animal reproduction research, no adverse effects of drugs on the fetus were seen.Or find that drugs have side effects in animal reproductive studies, but these side effects have not been confirmed among women in the control group and 3 months of pregnancy (nor have no evidence of harmfulness in the next six months).
There are not a lot of drugs for classification B. It is gratifying that some of the daily antibiotics are part of this category.For example, all penicillin and most cephalosporin drugs are B -type drugs.
What are the drugs that cannot be taken blindly in life?
Antibiotics, such as tetracycline and 霉omycin, inhibit bone development, can cause fetal congenital cataracts and finger malformations.The use of breastfeeding affects deciduous development.
Taking a lot of contraceptives in early pregnancy can cause fetal multi -organ deformities and chromosomal distortion, and adrenal corticosteroids may cause fetal cleft lip and palate.
Anti -allergic medicine, poker sensitivity can cause fetal cleft lip and palate, limb defect.
The analgesic drugs for relief, taking aspirin in the early pregnancy can cause fetal cleft lip and palate, kidney, cardiovascular, and nervous system deformities.
Anti -voltage diuretic drugs, such as bloodping, can slow the fetal heart rate, neonatal nasal congestion and lethargy.
Oral hypoglycemic drugs can cause fetal deformity.
Vitamins, excessive vitamins can cause fetal bone abnormalities, high neonatal blood calcium, intellectual obstacles or neonatal hypertrophymia.
Therefore, expectant mothers should follow the doctor’s advice during pregnancy and use medicine safely and reasonably.
