What is Pitocin or Oxytocin Used for in the Birth Process?

Pitocin or oxytocin is a drug which is given during labor which forces the uterus to contract in a more frequent way and with stronger contractions.
Doctors have a dosage scale that they used to give Pitocin and nurses and doctors attending to patients who are receiving Pitocin must be very careful to make sure that the contractions did not come too closely together or that they become too strong.  

Doctors and nurses can see how often and how strong contractions are by watching the contraction monitor.  Pitocin is given to help labor progress more quickly which can benefit the baby.  The key is that the doctors and nurses must be very observant when Pitocin is being given.
