1. Does taking drugs during pregnancy affect your baby?

New pregnant mothers need to pay attention!Taking drugs during different periods of pregnancy may have different degrees of impact on the fetus.It mainly includes the following three periods [1-2]::

1. Early cell proliferation: before fertilization to the third week of pregnancy; the medication before fertilization has no effect. If the fertilized egg is affected by the medicine within two weeks after fertilization, it may be eliminated naturally, and the output of labor is a safe period.

2. Organization period: 3rd to the third month of pregnancy; this stage cannot be ignored. If expectant mothers need to seek medical treatment in time if there is a physical discomfort, they cannot take medicine without permission.Throughout the stage, the fetal organs are gradually formed, the cells are accelerated and split, and they are easily affected by factors such as drugs. In order to avoid the occurrence of deformities in external force stimulation, medication care is needed during this period.

3. Period formation period: 3 months of pregnancy to full month, the final stage of fetal development; the fetus is basically mature. Except for the central nervous system or reproductive system, other organs generally do not teratogenic.However, the intensity and duration of the function of teratogenic factors can also affect the physiological function and development of the fetus.

Therefore, the new pregnant mother should inform the doctor in detail the time of the last menstrual period (cycle) and so on.

2. Under the circumstances during pregnancy?

1. The medication must be clearly indicated, avoid abuse, and avoid excessive panic and illness.

2. Users that are available or useless should be used as little as possible.

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

4. Avoid combined medication by being able to take medicine alone.

5. If necessary, try to use drugs that are less harmful to the fetus.

6. Affordable teratogenic drugs are prohibited.If pregnant women are in danger, they can be used after weighing the advantages and disadvantages carefully.

7. Forbidden test drugs during pregnancy, including pregnancy tests [1].

3. How should the impact of drugs on fetal fetuses be identified during pregnancy?

First of all, the impact of drugs on fetuses can refer to the US Food and Drug Administration (FDA) according to the danger of drugs to the fetus into five hazard levels of A, B, C, D, and X [3].

Class A: In the study of the control group, women who have 3 months of pregnancy have not seen signs of harm to the fetus (and there is no evidence of the harmfulness of the next 6 months), that is, the safety of medication during pregnancy, noneAdverse effects.

Class B: In the study of animal reproductiveness (no comparison study of pregnant women), no impact on the fetus was seen.There are adverse reactions in animal reproductive research, and some adverse reactions have not been confirmed in women who have not been 3 months pregnant (there is no evidence of the harmfulness of the next 6 months).

Category C: The study of animals proves that it has adverse reactions to the fetus (deformed or killed embryo), but did not study in women in the control group, or did not study parallel in women and animals.This type of drugs can only be applied after weighing the benefits of pregnant women than the harm to the fetus.

Category D: There is a clear evidence of the harmfulness of the fetus. Although it is harmful, pregnant women have absolute benefits after medication (for example, pregnant women are threatened by death or severe diseases, so it needs to be used.But), demand is more harmful.

Category X: Research on animals or people shows that it can make the fetus abnormal.Or it is harmful to people or animals based on experience.It is obviously unhelpful to apply such drugs in pregnant women.This type of drug is prohibited for pregnancy or patients with pregnancy.

Therefore, choosing A and B drugs as much as possible during pregnancy, Class C drugs need to weigh the advantages and disadvantages, and use it carefully under the guidance of a doctor. Unless the D -level drugs are in dying the life of pregnant women, or with other safer drugs invalidated, seriously invalidateThe disease is only considered, and the X -level drug must be strictly banned.Regarding the pregnancy grades of drugs, the following common drugs are enumerated:

Class A: Various vitamins, potassium chloride, left norexorine, etc. of normal doses.

Grade B: Most β -laidide drugs and macrolactone drugs, clinamycin, ethylene butanol, golovir, Akaba candy, di metarison, insulin, acetaminol, thunderbolt, thunderbolt, thunderNicotine, osoma, lactose, etc.
