Atosiban infusion 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.
- 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.

- 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.

The following information is only intended for healthcare professionals (see also section 3):
The vials should be inspected visually for particulate matter and discoloration prior to administration Atosiban is given intravenously in three successive stages:
- The initial intravenous injection of 6.75 mg in 0.9 ml is slowly injected into a vein over one minute.
- A continuous infusion at a rate of 24 ml/hour is given for 3 hours.
- A continuous infusion at a rate of 8 ml/hour is given for up to 45 hours, or until the contractions of the uterus have subsided.
The total duration of the treatment should be no more than 48 hours. Further treatment cycles of Atosiban can be used should contractions recur. It is recommended that no more than three retreatments should be used during a pregnancy.
Preparation of the intravenous infusion solution, following initial bolus injection of Atosiban 6.75 mg/0.9 ml solution for injection
For intravenous infusion, following the bolus dose, Atosiban 37.5 mg/5 ml concentrate for solution for infusion should be diluted in one of the following solutions:
- sodium chloride 9 mg/ml (0.9%) solution for injection
- Ringer's lactate solution
- 5% w/v glucose solution.
Withdraw 10 ml solution from a 100 ml infusion bag and discard. Replace it by 10 ml Atosiban 37.5 mg/5 ml concentrate for solution for infusion from two 5 ml vials to obtain a concentration of 75 mg atosiban in 100 ml.
The reconstituted product is a clear, colourless solution without particles.
The loading infusion is given by infusing 24 ml/hour (i.e. 18 mg/h) of the above prepared solution over the 3 hour period under adequate medical supervision in an obstetric unit. After three hours the infusion rate is reduced to 8 ml/hour.
Prepare new 100 ml bags in the same way as described to allow the infusion to be continued.
If an infusion bag with a different volume is used, a proportional calculation should be made for the preparation.
To achieve accurate dosing, a controlled infusion device is recommended to adjust the rate of flow in drops/min. An intravenous microdrip chamber can provide a convenient range of infusion rates within the recommended dose levels for Atosiban.
If other medicinal products need to be given intravenously at the same time, the intravenous cannula can be shared or another site of intravenous administration can be used. This permits the continued independent control of the rate of infusion.
