What Is Pitocin?
Medically reviewed by Peter Weiss, MD
Pitocin (oxytocin injection) is a synthetic form of oxytocin. Oxytocin is a hormone that causes the uterus to contract. It is given through an intravenous (IV) line to induce (start) or augment (speed up) contractions during labor.
This article will discuss Pitocin, including its purpose, risks, and complications.
Purpose
Pitocin (oxytocin injection) is given intravenously as a method of labor induction, typically at least 39 weeks into pregnancy. You may be given medication first to “ripen” your cervix (the lower part of the uterus) and prepare you for labor.
If you’ve already gone into labor naturally and aren’t progressing, your healthcare provider may give you Pitocin to speed up your contractions. Usually, Pitocin starts to stimulate contractions within about 30 minutes.
While Pitocin is being delivered through your IV drip, your medical team will monitor your blood pressure and contractions. They will also monitor your baby for any signs of fetal distress (inadequate oxygen supply).
How Many People Are Given Pitocin During Labor?
Estimates suggest that about 22% of pregnant people in the United States have their labor induced, often with a medication like Pitocin.
There are many possible medical reasons for labor induction. Your healthcare provider may recommend Pitocin if:
You are more than 42 weeks pregnant and haven’t gone into labor.
Your amniotic fluid (the fluid in the sac surrounding the fetus) level is low.
Your baby is experiencing intrauterine growth restriction (IUGR) and isn’t growing fast enough.
You have chorioamnionitis (an infection of the amniotic fluid and placenta—the organ that develops in the uterus to provide blood and nutrients to the developing fetus).
You have premature rupture of membranes (PROM), meaning that your amniotic sac ruptured on its own but you aren’t having contractions.
You have gestational diabetes.
You have high blood pressure.
There are problems with your heart, kidneys, or other major organs.
There are problems with the function or size of the placenta.
Pitocin may be administered on its own to induce or speed up labor contractions. Injectable oxytocin may also be used alongside other methods of labor induction, such as rupturing the amniotic sac (the sac that contains amniotic fluid and protects the fetus during pregnancy).

Risks
When used for medical reasons, Pitocin is typically safe and effective for both the pregnant person and fetus. Side effects of Pitocin may include:
Nausea
Vomiting
Fever during childbirth
In some cases, Pitocin may cause irregular and sometimes tetanic contractions. This can increase your risk of needing an emergency cesarean delivery (C-section) if your body is not ready. A C-section is the surgical delivery of the baby. The possible risks of a C-section include:
Blood loss
Infection
Bladder or bowel injuries
If your labor is induced and your due date wasn’t calculated correctly, you may have an increased risk of giving birth to a late preterm baby. A late preterm baby (born between 34 and 37 weeks) could have certain health and behavioral concerns, such as:
Jaundice (yellowing of the skin caused by excess bilirubin in the blood)
Breathing problems
Difficulty maintaining body temperature
Problems with breastfeeding
Developmental delays in early childhood
Because of the possible risks of an elective induction (an induction of labor for convenience or personal preference), you should ideally be given Pitocin only if it is medically necessary.
Who Should Not Be Given Pitocin?
In certain cases, it may not be safe to induce labor with Pitocin. Your healthcare provider may recommend that you have a C-section instead if certain conditions are present, such as:
Breech presentation (when the baby is positioned head up instead of head down)
Placenta previa (when the placenta partially or completely covers the cervix)
Infection, such as genital herpes
Umbilical cord prolapse (when the umbilical cord drops into the birth canal before the baby)
Cervical cancer
A history of uterine surgery or prior C-sections
Complications
While rare, some serious medical complications are possible when using Pitocin to induce labor. Severe complications from Pitocin may include:
Uterine rupture (tearing of the uterus)
Uterine hyperstimulation, which can cause contractions that are too long, frequent, or severe
Seizures (uncontrolled electrical activity in the brain) caused by low blood pressure or low sodium levels
Excessive bleeding
Symptoms of a severe allergic reaction, such as rash, hives, difficulty breathing, rapid heartbeat, or swelling
In very rare cases, Pitocin may cause fetal distress, fetal health complications, or stillbirth.
If you experience any side effects from Pitocin, let your healthcare provider know right away. They can decrease your dose or give you other medications to help to control your symptoms.

Summary
Pitocin (oxytocin injection) is a synthetic form of oxytocin—a hormone that stimulates the uterus. It is given intravenously to start or speed up labor contractions during childbirth.
Your healthcare provider may recommend using Pitocin to induce labor if you are more than 42 weeks pregnant or if your amniotic sac has already ruptured but your contractions haven’t started.
They may also recommend Pitocin due to certain medical conditions, such as a uterine infection, gestational diabetes, high blood pressure, restricted fetal growth, problems with the placenta, or problems with your major organs.
Side effects from Pitocin may include nausea, vomiting, and fever. In some cases, Pitocin may increase the risk of an emergency C-section. Serious complications from Pitocin, such as uterine rupture or excessive bleeding, are rare.
A Word From Verywell
When medically necessary, Pitocin can be a safe, effective way to induce labor. If you’re concerned about the potential side effects of Pitocin, talk to your healthcare provider as early as possible in your pregnancy.
