What VIATOCINON is used for
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 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 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 or nurse if you have any questions about why this medicine has been
prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is only available with a doctor's prescription.
Before you are given VIATOCINON
When you must not be given it
Do not take VIATOCINON if you have an allergy to:

any of the ingredients listed at the end of this leaflet
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue or other parts of the body
rash, itching or hives on the skin
You must not be given VIATOCINON if:
your doctor thinks that inducing or enhancing contractions for normal labour and vaginal
delivery would be unsuitable for you or your baby
there are maternal or foetal reasons for caesarean delivery
you have been given medicines called prostaglandins within the past 6 hours
If you are not sure whether you should be given this medicine, talk to your doctor
Before you are given it
Tell your doctor if you are allergic to any other medicines, foods, dyes, or preservatives.
Tell your doctor if you have high blood pressure or any heart or kidney problems.
Your doctor may want to take extra precautions. For example, the amount of fluid you
will be given may need to be reduced if you have a problem with your heart or kidneys.
Tell your doctor if you have or have had any of the following medical conditions:
an abnormal electrical signal called "prolongation of the QT interval"
any other conditions that affect the heart
If you have not told your doctor or nurse about any of the above, tell them before
you are given VIATOCINON.
Taking other medicines
Tell your doctor or nurse if you are taking any other medicines, including any that
you get without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and VIATOCINON may interfere with each other.
Tell your doctor if you have been given any anaesthetics or medicines called prostaglandins.
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 for 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.
Tell your doctor or nurse as soon as possible if you do not feel well while you are
being given VIATOCINON.
All medicines can have side effects. Sometimes they are serious, most of the time
they are not. You may need medical treatment if you get some of the side effects.

Ask your doctor or nurse to answer any questions you may have.

rash, itching or hives on the skin
swelling of the face, lips, tongue, throat or other parts of the body
shortness of breath, wheezing or troubled breathing
nausea (feeling sick) or vomiting
feeling drowsy and lethargic
pain in the abdomen that is different from labour pains
dizziness, light headedness or faintness
flushing of the face
fast, slow or irregular heartbeat
excessive or continuous contractions
