1. Why am I given VIATOCINON?
VIATOCINON contains the active ingredient synthetic oxytocin. VIATOCINON is a man-made chemical that is identical to a natural hormone called oxytocin.
It works by stimulating the muscles of the uterus (womb) to produce rhythmic contractions.
VIATOCINON is used to
bring on (induce) labour. It can also be used during and immediately after delivery
to help the birth and to prevent or treat excessive bleeding.
VIATOCINON is not suitable in all situations - for example, if the baby or placenta
are in the wrong position or if you have had a previous caesarean section or other
surgery involving the uterus. Your doctor can give you more information on the suitability
of this medicine for you.
Ask your doctor if you have any questions about why VIATOCINON has been prescribed
for you.
Your doctor may have prescribed it for another reason.
VIATOCINON is only available with a doctor's prescription.
2. What should I know before I am given VIATOCINON?

4. How VIATOCINON is given?
To bring on (induce) or maintain labour, VIATOCINON is given by intravenous infusion
(drip). The speed of the infusion is set to maintain a pattern of contractions similar
to normal labour. During the infusion, both you and your baby will be closely monitored
to prevent complications.
If VIATOCINON is needed at delivery or to prevent excessive bleeding, it can also
be given intramuscularly (into a muscle) or by slow intravenous injection directly
into a vein.
How much will you be given
Your doctor will decide what dose of VIATOCINON you will receive, depending on your
pattern of contractions.
5. Are there any side effects?
