What are the effects of taking anti-abortion drugs during pregnancy?

Pregnancy-maintaining drugs are a type of medicine that many women who have just become pregnant will choose to better ensure the healthy development of the fetus. Although pregnancy-maintaining drugs have little effect on the fetus, they do have a certain impact on pregnant women. In particular, pregnant women who are 28-37 weeks pregnant should not take pregnancy-stabilizing drugs, otherwise it will cause some adverse effects on the body. Female friends should pay special attention to this.

1. The effects of pregnancy-maintaining drugs on pregnant women

Doctors often recommend that pregnant women who show signs of miscarriage or premature birth use tocolytic drugs. Before using pregnancy-stabilizing drugs, many pregnant women always ask their doctors whether they will cause adverse harm to the fetus. During pregnancy, especially in the first three months, the risk of drug-induced teratogenesis increases because the differentiation of the fetus's organs has not yet been completed, which can induce serious consequences such as deformities.

Tocolytic drugs have little effect on the fetus because they are smooth muscle relaxants. Their use may cause side effects such as accelerated heartbeat and difficulty breathing. They may also lower blood pressure. If the reaction is severe, they may cause pulmonary edema or myocardial failure. However, the chance of these side effects is very low, and the use of injectable tocolytic drugs is more likely to cause problems. Therefore, there should not be too much concern about using tocolytics for pregnant women who show signs of miscarriage or premature birth. However, it is a medicine after all, so the doctor will decide whether to use tocolytic drugs based on the possible causes of miscarriage or premature birth of the pregnant woman.

2. Under what circumstances should pregnant women not use pregnancy-stabilizing drugs?

Professor Sun Jingxia said that if the pregnancy is between 28 and 37 weeks and there are symptoms of premature birth due to pregnancy-induced hypertension, uterine malformation, twins, polyhydramnios, etc., it is not recommended to preserve the fetus, because the fruit is not ripe and the stem has fallen off. The premature baby's organs are underdeveloped and the mortality rate is high. Even if the baby survives, he or she may suffer from intellectual disabilities.

3. Under what circumstances can the pregnancy be preserved?

First, for pregnant women who may have miscarriage due to corpus luteum dysfunction and progesterone deficiency, but whose ultrasound images show a live fetus, pregnancy preservation can be carried out. Signs of miscarriage caused by this reason should be treated with progesterone under the guidance of a doctor. Human chorionic gonadotropin (HCG) can also be used under the guidance of a doctor to promote the synthesis of progesterone.
