oxytocin

What is the most important information I should know about oxytocin?

Use only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

What is oxytocin?

Oxytocin is a hormone that is used to induce labor or strengthen uterine contractions, or to control bleeding after childbirth.

Oxytocin is also used to stimulate uterine contractions in a woman with an incomplete or threatened miscarriage.

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

What should I discuss with my healthcare provider before receiving oxytocin?

Tell your doctor if you have ever had:

• a severe infection in your uterus;
• a difficult labor because you have a small pelvis;
• genital herpes;
• cervical cancer;
• surgery on your cervix or uterus (including a prior C-section);
• high blood pressure; or
• heart problems.

How is oxytocin given?

Oxytocin is injected into a muscle, or given as an infusion into a vein. A healthcare provider will give you this injection.

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?

What happens if I overdose?

Since oxytocin is given by a healthcare professional in a medical setting, you will be constantly monitored to make sure you are receiving the correct dose.

What should I avoid while receiving oxytocin?

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

What are the possible side effects of oxytocin?

• a fast, slow, or uneven heart rate;
• excessive bleeding long after childbirth;
• severe headache, blurred vision, pounding in your neck or ears; or
• confusion, severe weakness, feeling unsteady.

Oxytocin may cause serious or life-threatening side effects in the newborn baby, including:

• slow heartbeats or other abnormal heart rate;
• jaundice (a yellow appearance of the baby's skin);
• a seizure;
• eye problems; or
• problems with breathing, muscle tone, and other signs of health problems.

Talk with your doctor about the risks of using oxytocin. In most cases, the benefits of inducing labor with oxytocin will outweigh the risks to the baby.

Common side effects may include:

• nausea, vomiting; or
• more intense or more frequent contractions (this is an expected effect of oxytocin).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect oxytocin?

Other drugs may affect oxytocin, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all other medicines you use.

Where can I get more information?
