Oxytocin

Pronunciation

Generic Name: oxytocin (ox-i-TOE-sin)
Brand Name: Pitocin

Oxytocin is used for:

Inducing labor in women with Rh problems, diabetes, preeclampsia, or when it is in the best interest of the mother or fetus. It is also used to help abort the fetus in cases of incomplete abortion or miscarriage, produce contractions during the third stage of labor, and control bleeding after childbirth.

Oxytocin is a uterine stimulant. It works by causing uterine contractions by changing calcium concentrations in the uterine muscle cells.

Do NOT use oxytocin if:

  • you are allergic to any ingredient in oxytocin
  • your birth canal is too small compared with the fetus's head
  • the fetus is in a difficult position within the womb or is in distress and delivery is not progressing
  • you have other complications that require medical intervention for birth
  • you have bacteria in the blood
  • you cannot have a child through vaginal delivery because of certain conditions (eg, genital herpes, cervical cancer)

Contact your doctor or health care provider right away if any of these apply to you.
