What medicine should I take after childbirth to shrink my uterus?

The reason why a small number of women are afraid of pregnancy is that during the pregnancy process, women have to face various unknown situations and the major problem of body shape change. Moreover, after giving birth, it is difficult for women's bodies to return to their pre-birth state. And during pregnancy, the baby in the belly expands the uterus, so the uterus needs to be contracted after giving birth. What kind of medicine can effectively shrink the uterus after childbirth?

1. Oxytocin injection

Indications and functions: Used for inducing labor, accelerating labor, and uterine bleeding caused by weak or poor uterine contractions after delivery and abortion; understanding the placental reserve function (oxytocin stimulation test).

Dosage:

1.1. For induction of labor or acceleration of labor, intravenous drip, 2.5 to 5 units at a time, diluted with sodium chloride injection to contain 0.01 units per 1 ml. At the beginning of intravenous drip, the dosage should not exceed 0.001-0.002 units per minute, and increase by 0.001-0.002 units every 15-30 minutes until uterine contractions are similar to those during normal delivery. The fastest dosage should not exceed 0.02 units per minute, and is usually 0.002-0.005 units per minute.

1.2. To control postpartum bleeding, drip 0.02-0.04 units per minute intravenously. After the placenta is expelled, 5-10 units can be injected intramuscularly.

Chemical composition: The main ingredient of this product is oxytocin. Structural formula: The structure of this product is a peptide bond consisting of 9 amino acids containing a disulfide bond. H-Cy3-Tyt-Ghu(NH2)-Asp(NH2)-Asp(NH2)-Cy3-Pro-Lcu-Gly-NH2.

Adverse reactions: Occasionally nausea, vomiting, increased heart rate or arrhythmia. Large doses may cause hypertension or water retention.

Contraindications: Narrow pelvis, obstructed birth canal, obvious cephalopelvic disproportion and abnormal fetal position, history of cesarean section, history of myomectomy, umbilical cord presentation or prolapse, placenta previa, fetal distress, excessive uterine contractions, uterine atony that is ineffective with long-term medication, antepartum bleeding (including placental abruption), multiple pregnancy, enlarged uterus (including polyhydramnios), and severe pregnancy-induced hypertension syndrome.

2. Ergonovine Maleate

Indications: Uterine bleeding caused by weak or poor uterine contraction after childbirth or miscarriage, and incomplete uterine recovery after childbirth.

Dosage and Administration: Rapidly and completely absorbed after oral or intramuscular injection. It takes about 6 to 15 minutes for oral administration, 2 to 3 minutes for intramuscular injection to start to produce uterine contractions, and immediate effect after intravenous injection. It is metabolized in the liver, excreted through the kidneys in the urine, and can also be excreted through breast milk.

Note:

2.1. It is not suitable for routine use by intravenous injection, as intravenous injection of this product may sometimes cause vomiting, cold sweats, pale complexion, and increased blood pressure. It is especially not suitable for postpartum women with hypertension syndrome. Pregnant women with cardiovascular disease are prone to pulmonary edema if given intravenous injection of this product, so it should be used with caution.

2.2. It is contraindicated for patients with cardiomyopathy, liver disease and pregnancy-induced hypertension syndrome. Because it can cause tonic contractions of the uterus, it is prohibited to use it before the fetus is delivered to avoid fetal distress or uterine rupture. Use with caution after delivery but before the placenta is delivered to avoid placenta becoming embedded in the uterine cavity.

2.3. Pregnant women and patients with vascular sclerosis or coronary artery disease should not use this product.

3. Oxytocin for injection

Indications and functions: Used for inducing labor, accelerating labor, and uterine bleeding caused by weak or poor uterine contractions after delivery and abortion; understanding the placental reserve function (oxytocin stimulation test).
