Presentation

Each ml injectable solution contains Carbetocin INN 100 mcg.

Description

Carbetocin is a long-acting synthetic octapeptide analogue of oxytocin. It acts as an agonist at peripheral oxytocin receptors, particularly in the myometrium of uterus.

Indications

Carbetocin is indicated for the prevention of uterine atony and postpartum haemorrhage (excessive bleeding) following delivery of the infant by elective caesarean section under epidural or spinal anaesthesia.

Dosage & Administration

A single intravenous dose of 100 mcg (1 ml) of Carbate (carbetocin injection) is administered by bolus injection, slowly over 1 minute, only when infant delivery has been completed by caesarean section under epidural or spinal anaesthesia.

Carbate is to be used as a single dose only.

Side Effects

10-40% of patients experienced nausea, vomiting, abdominal pain, itching skin, increased body temperature, trembling and weakness. Infrequent adverse events (1-5% of patients) included back pain, dizziness, metallic taste, anaemia, sweating, chest pain, dyspnoea, chills, tachycardia and anxiety.

Precautions

In patients who may not have an adequate uterine contraction after a single injection of carbetocin, more aggressive treatment with additional doses of oxytocin or ergometrine is warranted.

As carbetocin is closely related in structure to oxytocin, hyponatraemia may occur.

Carbetocin should be used cautiously in the presence of epilepsy, migraine, asthma or any state in which a rapid addition to extracellular water may produce hazard for an already overburdened system.

Patients with eclampsia and pre-eclampsia should be monitored for changes in blood pressure.

Carbetocin is not recommended for use in elderly patients.

Use in Pregnancy & Lactation

Use of carbetocin injection is contraindicated during pregnancy.

Use in lactation

Small amounts of carbetocin has been shown to cross over from plasma into the breast milk of nursing women. The small amount of carbetocin ingested by infant would not be expected to present a significant safety concern.

Drug Interaction

No specific drug interactions have been reported with carbetocin.

Over Dose

Overdosage of carbetocin can be expected to produce enhanced pharmacological effects associated with uterine hyperactivity and pain. Treatment consists of symptomatic and supportive management.
