Tractocile – Atosiban uses, dose and side effects


6.75 mg/0.9 ml solution 

for injection

What Tractocile is and what it is used for

Tractocile contains atosiban. Tractocile can be used to delay a premature birth of your baby. Tractocile is used in adult pregnant women from week 24 to week 33 of pregnancy.

Tractocile works by making the contractions in the uterus less strong. It also makes contractions less frequent. This happens by inhibiting the effect of a natural hormone in the body called oxytocin , which causes the uterus to contract.

What you need to know before using Tractocile

Do not use Tractocile

  • if your pregnancy is less than 24 weeks
  • if your pregnancy exceeds 33 weeks
  • if the water has broken ( premature rupture of membranes) after 30 weeks of pregnancy or more
  • if your unborn child (fetus) has an abnormal heart rate
  • if you have uterine bleeding and the doctor wants the baby to be born right away
  • if you have something called “severe pre-eclampsia” and the doctor wants the baby to be born right away. Severe pre- eclampsia means high blood pressure , fluid retention and/or egg whites in the urine.
  • if you have something called “eclampsia” which is similar to “severe pre-eclampsia” but you also get cramps. This means that the baby must be born immediately.
  • if your unborn child has died
  • if you have an infection or suspected infection in the uterus
  • if the placenta covers the birth canal
  • if the placenta is about to detach from the uterine wall
  • if you or your unborn child have other conditions where continuing the pregnancy is considered risky
  • if you are allergic to atosiban or any of the other ingredients of this medicine (listed in section 6)

Do not use Tractocile if any of the above applies to you. If you are not sure, talk to your doctor, midwife or pharmacist before receiving Tractocile.

Warnings and precautions

Talk to your doctor, midwife or pharmacist before receiving Tractocile:

  • if you think your water has broken ( premature rupture of 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 child
  • if the contractions return, the Tractocile treatment can be repeated 3 more times
  • if your unborn child is small in relation to the length of the pregnancy
  • the uterus may be less likely to contract when your baby is born, this may cause bleeding
  • if you are pregnant with more than one child and/or are receiving medicines to delay the premature birth of your child such as blood pressure lowering medicines. This can increase the risk of pulmonary edema ( accumulation of fluid in the lungs).

If any of the above apply to you (or if you are not sure), talk to your doctor, midwife or pharmacist before receiving Tractocile.

  • then another continuous infusion (drip) is given at a dose of 6 mg/hour for up to 45 hours or until uterine contractions subside.

The treatment should not exceed 48 hours in total.

Tractocile can be used again, should the contractions return. Treatment with Tractocile can be repeated up to three times.

During treatment with Tractocile, your contractions and fetal heart rate may be monitored.
