Hypersensitivity to carbetocin, oxytocin, or any component of the formulation; administration prior to delivery of infant for any reason (including elective or medical induction of labor); serious cardiovascular disorders; use in children
Concerns related to adverse effects:
• Antidiuretic effect: May produce antidiuretic effect; risk of water intoxication cannot be excluded.
• Bleeding: Persistent bleeding warrants further evaluation to rule out coagulopathy, genital tract trauma, or the presence of retained placental fragments.
Disease-related concerns:
• Asthma: Use with caution in patients with asthma.
• Cardiovascular disease: Use has not been studied in patients with known coagulopathy; use with extreme caution in patients with cardiovascular disease (contraindicated in serious cardiovascular disorders), especially coronary artery disease.
• Epilepsy: Use with caution in patients with epilepsy.
• Migraines: Use with caution in patients with migraines.
Other warnings/precautions:
• Appropriate use: Carbetocin induced contractions are of a longer duration than those observed with oxytocin and are not stopped by discontinuation of therapy. Improper use during pregnancy may produce symptoms similar to those observed with oxytocin overdosage (eg, hyperstimulation of uterus with strong or prolonged contractions, tumultuous labor, uterine rupture, cervical and vaginal lacerations, postpartum hemorrhage, utero-placental hypoperfusion and variable deceleration of fetal heart rate, fetal hypoxia, hypercapnia, or death). Therapy should not be repeated if response to initial dose is inadequate; aggressive therapy with alternative agents (eg, oxytocin, ergonovine) should be utilized.

Carbetocin is indicated for the prevention of postpartum hemorrhage following vaginal or cesarean delivery; use prior to delivery is contraindicated.
Carbetocin induced contractions are of a longer duration than those observed with oxytocin and are not stopped by discontinuation of therapy. Improper use during pregnancy may produce symptoms similar to those observed with oxytocin overdosage (eg, hyperstimulation of uterus, uterine rupture).
Carbetocin is present in breast milk.
Carbetocin was detected in the breast milk of 5 healthy breastfeeding women ~7 to 14 weeks postpartum though peak levels observed were 50 times lower than in plasma (Silcox 1993). Exposure to the breastfeeding infant is expected to be minimal and not expected to pose significant health risks as carbetocin in breast milk is rapidly degraded in the GI tract of a breastfeeding infant.
Milk let-down occurred normally in 5 breastfeeding women following a dose of carbetocin 70 mcg IM.
Heart rate, BP, blood loss, temperature (FIGO [Escobar 2022]).
Binds oxytocin receptors located in uterine smooth muscle producing rhythmic uterine contractions characteristic to deliver, as well as increasing both the frequency of existing contractions and uterine tone. Enhances uterine involution early in postpartum.
Onset of action: IV: 1.2 ± 0.5 minutes.
Distribution: Vd: 22 L.
Bioavailability: IM: 77%.
Duration: IV: ~60 minutes; IM: ~120 minutes (Sweeney 1990; WHO 2018).
Half-life elimination: Terminal: IV: 33 minutes; IM: 55 minutes.
Time to peak: IM: 30 minutes (median).
Excretion: IV: Urine (<1%, as unchanged drug).
