What is Syntocinon (Oxytocin) Nasal Spray used for?

Syntocinon (Oxytocin) Nasal Spray is used for the inducement of contractions. In addition it is used for the stimulation of labour in woman who have too week contractions. Beyond that oxitocin is known as an excellent bleeding controller and preventer. Syntocinon may also be applied during a caesarian section and for the management of certain types of miscarriage.

Syntocinon comprises a synthetic version of the naturally occurring body hormone oxytocin. The oxytocin causes the muscles of the woman's uterus to contract during contractions so that the suckling can be pressed out. Towards the end of pregnancy, oxytocin normally is released naturally by the brains pituitary gland to stimulate the muscle of the uterus. Synthetic oxytocin is designed to activate contractions for medical reasons and for those cases when contractions do not start naturally. The dosage is regulated until the point is reached that the created contractions are raised to a natural pattern of normal labour.

Beyond that synthetic oxytocin may also be used for the stimulation of contractions which have started naturally, but are considered too weak to press out the suckling. In such circumstances syntocinon will be able to support the strengthening of the contractions of the uterus.

After birth syntocinon can be prescribed for the prevention of heavy bleeding and to support the compression of the placenta.
