What are the side effects of pregnancy-preserving drugs?

If a pregnant woman experiences some uncomfortable symptoms during pregnancy, such as vaginal bleeding and abdominal pain, this may be a sign of miscarriage. At this time, she needs to take measures to protect the fetus. One of the more important methods is to take some fetal protection drugs. At this time, she must do so under the guidance of a doctor. If she takes fetal protection drugs indiscriminately, it will cause adverse effects.

1. Side effects such as accelerated heartbeat

The use of pregnancy-preserving drugs may also cause side effects such as accelerated heart rate and difficulty breathing, and may also lower blood pressure. If the reaction is severe, it may also cause pulmonary edema or myocardial failure.

2. Causes prolonged pregnancy

Excessive progesterone in the late pregnancy can delay the pregnancy and cause a post-term pregnancy. Post-term pregnancy not only causes birth injuries and pain to pregnant women, but more importantly, it causes the placenta to age and the fetus is prone to suffocation due to lack of oxygen.

3. Cause fetal genital malformation

Excessive progesterone can also cause fetal genital malformations, masculinizing female fetuses and causing malformations such as hypospadias in male fetuses. In addition, pregnant women's digestive function decreases, stomach acid decreases, and they experience discomfort such as heartburn, bloating, and constipation. These are also the consequences of excessive intake of progesterone during pregnancy, which slows down the contraction of gastrointestinal smooth muscles.

For women who are 28 to 37 weeks pregnant and have symptoms of premature birth due to pregnancy-induced hypertension, uterine malformation, twins, polyhydramnios, etc., it is not recommended to preserve the fetus. Because the melon is not ripe and the stem has fallen off at this time, the premature baby's organs are underdeveloped and the mortality rate is high. Even if they survive, they may suffer from intellectual disabilities later in life.

First, for pregnant women who may have miscarriage due to corpus luteum dysfunction and progesterone deficiency, but whose B-ultrasound images show a live fetus, pregnancy preservation can be carried out. Abortion caused by this reason should use 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.
