1. What Atosiban SUN is and what it is used for

Atosiban SUN contains atosiban. Atosiban SUN is used to delay the premature birth of your baby. Atosiban SUN is used in pregnant adult women, from week 24 to week 33 of the pregnancy.

Atosiban SUN works by making the contractions in your womb (uterus) weaker. 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 are given Atosiban SUN

Do not use Atosiban SUN

  • If you are allergic to atosiban or any of the other ingredients of this medicine (listed in section 6).
  • 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.

Do not use Atosiban SUN 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 SUN.

Warnings and precautions

Talk to your doctor, midwife or pharmacist before you are given Atosiban SUN

  • 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 SUN 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 SUN.

Children and adolescents

Atosiban SUN has not been studied in pregnant women less than 18 years old.

3. How Atosiban SUN will be given

Atosiban SUN 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.

  • 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 SUN can be used if your contractions start again. Treatment with Atosiban SUN can be repeated up to three more times.
