Description: Oxytocic Agent
“ALERT: US Boxed Warning
Elective induction of labour is defined as the initiation of labour in a pregnant individual who has no medical indications for induction. Since the available data are inadequate to evaluate the benefits-to-risks considerations, oxytocin is not indicated for elective induction of labour.”

How Does It Work
Oxytocin is a hormone secreted by the hypothalamus and stimulates the contraction of uterine muscle during gestation and milk ejection through a neurohormonal reflex. Oxytocin also released during sexual intercourse in both men and women which has led researchers to coin it as the sexual bonding hormone.
Indications For Use
Antepartum and postpartum, breastfeeding, anorgasmia, post-orgasmic penile detumescence, intensifying sexual arousal.
Do not use in patients with a known hypersensitivity to oxytocin or any component of the formulation.
Do not use if there is a cephalopelvic disproportion; unfavourable fetal position; hypertonic or hyperactive uterus; obstetrical emergencies where surgical intervention if favored.
Do not use in cases of severe toxemia; premature or unripe cervix; uterine rupture, previous caesarian delivery; prolonged uterine inertia; factors predisposing to thromboplastin or amniotic fluid embolism.
Can cause severe water intoxication when administered in large doses.
Use with caution in hemodynamically unstable patients.
Usual (IV): Administration requires the use of an infusion pump. The ideal dosing regimen has not been determined and various protocols are available.
Discontinue the oxytocin infusion immediately in the event of uterine hyperactivity and/or fetal distress. If uterine contractions become too powerful, the infusion can be stopped abruptly. Infuse 0.5 to 1 milliunits/minute; gradually increase the dose in increments of 1 to 2 milliunits/minute every 30 to 60 minutes until desired contraction pattern is established; dose may be decreased by similar increments after the desired frequency of contractions is reached and labour has progressed to 5 to 6 cm dilation.
