Oxytocin generally refers to contractions. Oxytocin dripped too quickly may cause side effects such as nausea, vomiting, excessive contractions, fever, etc. The specific situation varies from person to person due to each person’s different physical condition and different drug resistance. Oxytocin generally refers to the contraction of the uterus. After a pregnant woman’s gestation period exceeds 41 weeks or when the contractions are not strong, the doctor can promote contractions and speed up the labor process by administering drops of oxytocin. Some pregnant women may experience side effects such as nausea, vomiting, excessive contractions and fever after using oxytocin. If pregnant women use oxytocin in large doses, it may cause water and sodium retention, and in severe cases, complications such as water intoxication and hyponatremia may occur. Care should be taken to control the concentration and speed when using oxytocin. If the concentration is too high or the speed is too fast, it will easily cause excessive contractions, which may cause uterine rupture or intrauterine distress in severe cases. Pregnant women need to be evaluated by a doctor before they are ready to use oxytocin. If the pregnant woman has fetal malposition, pelvic or birth canal abnormalities, the use of oxytocin is usually not recommended to avoid adverse effects on the fetus and the pregnant woman.
