Did you know that oxytocin is often called the “love hormone” or “bonding hormone” because of its powerful role in human connection and maternal bonding? Beyond emotions, oxytocin plays a critical role in childbirth and breastfeeding. In medical settings, synthetic oxytocin is often administered to support labour and postnatal recovery.
While oxytocin offers vital benefits, especially during labour, both its natural and synthetic forms can cause side effects, some mild, others potentially serious. Awareness of these effects can help patients and carers respond appropriately when complications arise.
According to the World Health Organisation (WHO), misuse or overuse of oxytocin can increase maternal and neonatal risks. So, here are the key side effects to be aware of:
One of the most serious side effects of synthetic oxytocin is uterine hyperstimulation, where the uterus contracts too frequently or too strongly. This condition can reduce oxygen supply to the baby, leading to foetal distress. Common signs include:
Prompt medical intervention is essential to safeguard both the mother and the baby.
Many women experience nausea, vomiting, or abdominal cramps while receiving oxytocin during labour. These effects are usually temporary and may be managed with supportive care.
Changes in blood pressure due to oxytocin may lead to headaches, dizziness, or light-headedness. Such symptoms must be monitored closely, especially in women with pre-existing hypertension or cardiovascular conditions.
Oxytocin has an antidiuretic effect, which can cause the body to retain water. This may result in a rare but serious condition known as water intoxication, or hyponatraemia. Symptoms include:
These complications are more likely during prolonged infusions or when large volumes of fluids are administered alongside oxytocin.
Though rare, some individuals may develop allergic reactions to synthetic oxytocin. Signs include:
Oxytocin is a hormone secreted by the pituitary gland in the brain. It has various physiological and emotional functions. In clinical settings, healthcare providers administer synthetic oxytocin, commonly known by its brand name Pitocin, to:
However, like any medication, oxytocin use must be carefully monitored to avoid adverse outcomes.
Oxytocin affects emotional regulation and behaviour. While often linked to positive feelings like trust and bonding, elevated oxytocin levels, especially if it is naturally occurring, can sometimes lead to increased emotional sensitivity or anxiety.
These psychological effects are more thoroughly studied in natural oxytocin and less so in patients receiving the synthetic form.
