After taking the medicine and found that I was pregnant, does it affect the fetus?Medication during pregnancy, remember these "iron laws"

Recently, many friends are consulting the problem of preparing pregnancy, and expectant mothers are very worried about consulting. "I have just taken medicine and found that I am pregnant, will it affect the fetus?"

How to take medicine during pregnancy is indeed a problem. Some people mistakenly take medicine, causing an irreversible effect; there is another extreme, that is, dare not take medicine any disease, and it will also affect the fetus.So, how to take medicine during pregnancy is safe and reasonable?

I don’t know if I took medicine during pregnancy, it usually has no effect

Many people are most concerned about that they have taken medicine and are worried about whether they will affect the fetus.

Liu Kefeng, the Department of Pharmacy of Zheng Dayi Affiliated Hospital, said that in our daily life, many pregnant mothers will have such concepts. They believe that taking drugs during pregnancy will definitely affect the fetus, so they are afraid of medication.In fact, this concept is wrong. As long as you consult a doctor or pharmacist with caution, the medication during pregnancy does not necessarily affect the fetus, and not all drugs may harm the fetus.

Some pregnant mothers are worried that the medication will affect the fetus, so they dare not take medicine regardless of the disease. As a result, delaying the illness is not good for the development of themselves and the fetus.Therefore, pregnant mothers cannot be busy with medication as soon as they are sick, nor can they completely reject medicines. The most important thing is "correct medication under the guidance of a doctor."

Liu Kefeng said that in terms of the impact of drugs during pregnancy, the effect of drugs on embryos within 1 to 2 weeks after fertilization is "all or none", that is, there is no impact, or the impact will cause abortion. Generally, it will not cause fetal malformations. ThereforeWhen you do n’t know if you take medicine before or early pregnancy, you do n’t have much impact on the fetus. You do n’t have to worry too much, and you do n’t have to do artificial abortion.

However, the stage that needs to be used most carefully during pregnancy is 3 to 8 weeks after fertilization (5-10 weeks of menopause), which is the first three months we often say.During this time, it is called the teratogenic sensitivity period. It is the period of differentiation of various organs of embryos. It is very vulnerable to external factors such as drugs and cause fetal malformations. There is no need to be decisive during this period, including general health products and nourishing drugs.If you have to take medicine, you must be careful and safe under the guidance of a doctor.If there is a history of taking medicine, you can take pre -delivery diagnosis (including B -ultrasound) at 16-20 weeks of pregnancy, and further understand the growth and development of the fetus and exclude fetal malformations.

In the middle and late pregnancy, selective medication

In the middle and late pregnancy, the organs of the fetus were basically differentiated during this period and continued to grow.During this time, the possibility of teratogenic teratogenic is greatly reduced, but some drugs may still affect the normal development of the fetus.

Before childbirth, the medicine must be very cautious

Pregnant women should be very cautious in the last week, because when the fetus becomes a newborn baby, the metabolic system in the body is not perfect, and the drugs cannot be quickly and effectively eliminated. The drug may accumulate and produce excessive drugs in the baby’s body.For example, Yuling will inhibit the hematopoietic function of newborns, causing jaundice, hemolytic anemia, etc.; Some drugs can cause hypoglycemia for newborns; even some drugs can cause fetal death.

What kind of medicine can be used?

Liu Kefeng said that at present, when evaluating the degree of harm of drugs to pregnant women and fetuses, it is mainly based on the standards promulgated by the US Food and Drug Administration (FDA).Commonly used drugs can be divided into A, B, C, D, and X.

Class A drug: Observed by clinical control, no damage to the fetus is seen, and it is the safest type of drug.

Class B drugs: No damage to fetal livestock was seen in animal tests, but lack of clinical control observation information; or observed damage to fetal livestock was observed in animal tests, but clinical control observation research failed to confirm.

Generally speaking, A and B drugs are drugs that have no or almost no harm to the fetus and pregnant women. They can generally be used safely during pregnancy, such as a variety of vitamins and calcium, as well as some antibiotics, such as penicillin, cephalosporins, etc.

Class C drugs: Animal experiments and clinical control observation data are not available; or they have damage to animals and livestock, but lack of clinical control observation information.The selection of such drugs is the most difficult, and many commonly used drugs during pregnancy belong to this category.

Class D drugs: There are certain clinical data to indicate that drugs are damaged to the fetus, but clinically needed, and lack of alternative drugs. At this time, it can weigh the severity of its harmfulness and the severity of clinical indications.

Among them, C and D drugs are harmful to the fetus (teratogenic or miscarriage), but it is good for pregnant women.Such as some antibiotics, hormone drugs, such as amino glycoside (C, D grade): galcoprotein, rinomycin, scatomycin, etc.

Class X Drugs: Animal experimental results and clinical data descriptions are highly harmful to the fetus, and generally exceeded the favorable benefits of the treatment application, which is a drug disabled during pregnancy.Anti -cancer drugs, sex hormones (estrogen, synthetic progesterone), etc.

In addition, some antipyretic analgesic drugs, such as aspirin, can lead to doses of death through the placenta, causing teratogenic;If you need to heat up, you can generally choose a highly safe acetaminol.

Liu Kefeng said that in general, as long as the medicine is followed by the following principles during pregnancy, it can generally ensure safety and reliability.

1. The application of any drug should be taken under the guidance of a doctor. Do not buy it yourself.

2. If those who need long -term medication due to special diseases such as thyroid disease, epilepsy, and systemic lupus erythematosus, you should first inform the doctor and consult the doctor.The disease caused the disease.

3. Regular prenatal examination to understand the condition of the fetus.

4. When taking drugs, pay attention to the words "pregnant women with caution, avoiding, disable" on the packaging.

5. Do not listen to the reinforcement and secret recipe and abuse the drug.

6. Drugs that can be used less;

7. When two or more drugs have the same or similar curative effect, consider using drugs that are less harmful to the fetus.

8. Avoid combined medication to be able to use medicine alone. You do n’t need to be more new.

9. Pay attention to the gestational week for medication, strictly grasp the dosage and duration.Adhere to the reasonable medication, stop the medicine in time after control.

10. Traditional Chinese medicine is not necessarily safe for pregnant women. Pay particular attention to Chinese medicines such as promoting blood circulation, diuretic, eliminating diet, stool, and falling damage.

11. Some diseases such as fever and diarrhea, pregnant women need to take medicine to solve it, so as not to adversely affect the fetus.
