What is Pitocin?

Pitocin is a natural hormone that causes the uterus to contract.

Pitocin is used to induce labor or strengthen labor contractions during childbirth, and to control bleeding after childbirth. This medicine is also used to stimulate uterine contractions in a woman with an incomplete or threatened miscarriage.

Pitocin may also be used for purposes not listed in this medication guide.

Important Information

Before you receive Pitocin, tell your doctor about all your medical conditions or allergies, and all the medicines you are using.

Before taking this medicine

You should not receive Pitocin if you have ever had an allergic reaction to Pitocin.

To make sure Pitocin is safe for you, tell your doctor if you have ever had:

  • genital herpes;

  • diabetes;

  • high blood pressure;

  • a heart rhythm disorder;

  • cervical cancer;

  • a severe infection in your uterus;

  • five or more pregnancies;

  • a difficult labor because you have a small pelvis;

  • surgery on your cervix or uterus (including a prior C-section); or

  • if you are less than 37 weeks pregnant.

Also tell your doctor if you are breast-feeding a baby.

How is Pitocin given?

Pitocin is injected into a vein through an IV. You will receive this injection in a hospital setting.

Your contractions and other vital signs will be watched closely while you are receiving Pitocin. This will help your doctor determine how long to treat you with this medication.

During labor, your baby's heart rate will also be watched with a fetal heart monitor to evaluate any effects of oxytocin on the baby.

What happens if I miss a dose?

Because you will receive Pitocin in a clinical setting, you are not likely to miss a dose.

What happens if I overdose?

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

What should I avoid after receiving Pitocin?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
