At a glance
Oxytocin is a hormone and medication used for induction of labor, stimulation of uterine contractions, prevention and treatment of postpartum hemorrhage and stimulation of lactation.
Indications
- Induction of labor
- Stimulation of uterine contractions
- Prevention and treatment of secondary postpartum hemorrhage
- Adherent placenta
- Stimulation of lactation
- Treatment of incomplete abortion (to prevent secondary hemorrhage)
Pharmacology
Oxytocin binds to specific receptors in uterine smooth muscle to increase intracellular calcium, activating myosin light chain kinase to cause uterine contractions. It also increases local prostaglandin production which further stimulates contraction.
Dosage
Labor Induction (IV):
- 0.5-1 mUnit/min (initial); titrate 1-2 mUnit/min q15-60min until contraction pattern similar to normal labor (usually 6 mUnit/min)
- Decrease dose after desired frequency reached and labor progressed to 5-6 cm dilation
Postpartum Hemorrhage (IV): 10-40 units (max 40 units) in 1000 mL nonhydrating IV solution
Incomplete Abortion (IV): 10-20 mUnit/min; not to exceed 30 units/12 hr
IM: 2-5 IU (postpartum); 2 IU (lactation); 2-5 IU every 30-60 min (incomplete abortion)
Side effects
Common Side Effects:
- Vomiting
- Headache
- Uterine contractions
- Nausea
- Uterine hypertonicity, spasm, titanic contraction or uterine rupture
- Water intoxication (with convulsions and coma)
- Cardiac arrhythmias
- Anaphylactic reaction
Use in pregnancy
Use in Pregnancy: Oxytocin is safe during pregnancy; low or no risk to fetus.
Pregnancy Category: A — always consult a doctor before taking during pregnancy.
Precautions & warnings
- Uterine sensitivity varies; use lowest effective dose
- Monitor fetal heart rate and maternal blood pressure
- Caution if uterine or cervical scars exist
- Caution while driving (contractions may begin)
Overdose effects
Overdose: Violent uterine contractions, fetal bradycardia, arrhythmias, tissue laceration, uterine rupture, fetal or maternal death; discontinue infusion and induce tocolysis.
Storage conditions
Store at 2-8°C, in dark and frost-free place; keep out of reach of children.
