5 Warnings and Precautions

PRECAUTIONS

Additions and/or revisions underlined:

Pregnancy

Oxytocin injection is used in pregnancy for (1) induction of labor in patients with a medical indication for the initiation of labor; (2) stimulation or reinforcement of labor, as in selected cases of uterine inertia; and (3) adjunctive therapy in the management of incomplete or inevitable abortion. There are no known indications for use of oxytocin in the first and second trimester of pregnancy other than in relation to spontaneous or induced abortion. Based on the wide experience with this drug and its chemical structure and pharmacological properties, it would not be expected to present a risk of fetal abnormalities when used as indicated.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Nonteratogenic Effects—See ADVERSE REACTIONS in the fetus or infant.

Labor and Delivery—See INDICATIONS AND USAGE.

Lactation (replaces ‘Nursing Mothers’)

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when oxytocin is administered to a nursing woman.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for (Oxytocin Injection) and any potential adverse effects on the breastfed child from (Oxytocin Injection) or from the underlying maternal condition.
