Oxytocin (Systemic)

Brand Names : Pitocin, Syntocinon

Side Effects of This Medicine

Oxytocin can be very useful for helping labor. However, there are certain risks with using it. Oxytocin causes contractions of the uterus. In women who are unusually sensitive to its effects, these contractions may become too strong. In rare cases, this may lead to tearing of the uterus. Also, if contractions are too strong, the supply of blood and oxygen to the fetus may be decreased.

Oxytocin has been reported to cause irregular heartbeat and increase bleeding after delivery in some women. It has also been reported to cause jaundice in some newborn infants.

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention:
