Oxagon IV Injection 100 mcg/ml

Uses

Oxagon IV Injection 100 mcg/ml is used 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.

Oxagon IV Injection 100 mcg/ml is also used to associated treatment for these conditions: Postpartum Haemorrhage (PPH), Uterine Atony

How Oxagon IV Injection 100 mcg/ml works

Oxagon IV Injection 100 mcg/ml binds to oxytocin receptors present on the smooth musculature of the uterus, resulting in rhythmic contractions of the uterus, increased frequency of existing contractions, and increased uterine tone. The oxytocin receptor content of the uterus is very low in the non-pregnant state, and increases during pregnancy, reaching a peak at the time of delivery.

Dosage

Oxagon IV Injection 100 mcg/ml dosage

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.

Precaution

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.Oxagon IV Injection 100 mcg/ml 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.Oxagon IV Injection 100 mcg/ml is not recommended for use in elderly patients.
