Warnings

Experienced physician/equipped facility

Wait at least 6 to 12 hr after administration of gel before using IV oxytocin, a dosing interval of at least 30 min is recommended after removal of insert. Monitor patient closely for adverse reactions including nausea, vomiting, or diarrhea. Monitor vital signs frequently during administration, noting especially any increase in temperature and hypertension or hypotension. Monitor for hypersensitivity reactions such as bronchospasms, cardiac arrhythmias or seizures.

Pregnancy

Category C . Contraindicated if fetus in utero has reached viability stage except when cervical ripening is indicated.

Lactation

Undetermined.
