3. HOW TO USE ATOSIBAN
Atosiban will be given to you in a hospital by a doctor, nurse or midwife.
They will decide how much you need. They will also make sure the solution
is clear and free from particles.
Atosiban will be given into a vein (intravenously) in three stages:
• The first injection of 6.75 mg in 0.9 ml will be slowly injected into your vein
over one minute.
• Then a continuous infusion (drip) will be given at a dose of 18 mg per hour
for 3 hours.
• Then another continuous infusion (drip) at a dose of 6 mg per hour will be
given for up to 45 hours, or until your contractions have stopped.
Treatment should last no longer than 48 hours in total.
Further treatment with Atosiban can be used if your contractions start again.
Treatment with Atosiban can be repeated up to three more times.
During treatment with Atosiban, your contractions and your unborn baby’s
heart rate may be monitored.
It is recommended that no more than three re-treatments should be used
during a pregnancy.

1. WHAT ATOSIBAN IS AND WHAT IT IS USED FOR
Atosiban solution for injection contains atosiban. Atosiban can be used to
delay the premature birth of your baby. Atosiban is used in pregnant adult
women, from week 24 to week 33 of the pregnancy.
Atosiban works by making the contractions in your womb (uterus) less
strong. It also makes the contractions happen less often. It does this by
blocking the effect of a natural hormone in your body called “oxytocin” which
causes your womb (uterus) to contract.

2. WHAT YOU NEED TO KNOW BEFORE YOU USE ATOSIBAN
Do not use Atosiban:
• If you are less than 24 weeks pregnant.
• If you are more than 33 weeks pregnant.
• If your waters have broken (premature rupture of your membranes) and
you have completed 30 weeks of your pregnancy or more.
• If your unborn baby (foetus) has an abnormal heart rate.
• If you have bleeding from your vagina and your doctor wants your unborn
baby to be delivered straight away.
• If you have something called “severe pre-eclampsia” and your doctor
wants your unborn baby to be delivered straight away. Severe
pre-eclampsia is when you have very high blood pressure, fluid retention
and/or protein in your urine.
• If you have something called “eclampsia” which is similar to “severe
pre-eclampsia” but you would also have fits (convulsions). This will mean
your unborn baby needs to be delivered straight away.
• If your unborn baby has died.
• If you have or could have an infection of your womb (uterus).
• If your placenta is covering the birth canal.
• If your placenta is detaching from the wall of your womb.
• If you or your unborn baby have any other conditions where it would be
dangerous to continue with your pregnancy.
• If you are allergic to atosiban or any of the other ingredients of this
medicine (listed in section 6).
Do not use Atosiban if any of the above apply to you. If you are not sure, talk
to your doctor, midwife or pharmacist before you are given Atosiban.
Warnings and precautions
Talk to your doctor or pharmacist or nurse before using Atosiban:
• If you think your waters might have broken (premature rupture of your
membranes).
• If you have kidney or liver problems.
• If you are between 24 and 27 weeks pregnant.
• If you are pregnant with more than one baby.
• If your contractions start again, treatment with Atosiban can be repeated
up to three more times.
• If your unborn baby is small for the time of your pregnancy.
• Your womb may be less able to contract after your baby has been born.
This may cause bleeding.
• If you are pregnant with more than one baby and/or are given medicines
that can delay the birth of your baby, such as medicines used for high
blood pressure. This may increase the risk of lung oedema (accumulation
of fluid in the lungs).
If any of the above apply to you (or you are not sure), talk to your doctor,
midwife or pharmacist before you are given Atosiban.
Children and adolescents
Atosiban has not been studied in pregnant women less than 18 years old.
Other medicines and Atosiban
Tell your doctor or pharmacist if you are using, have recently used or might
use any other medicines.
Pregnancy, breast-feeding and fertility
You should only be given this medicine if you are between 24 and 33 weeks
of pregnancy. If this does not apply to you, please speak to your doctor.
If you are still breast feeding a child from an earlier pregnancy, you should
stop during your treatment with Atosiban, as breastfeeding may stimulate
uterine contractions
