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

Atosiban Altan contains atosiban. Atosiban may be used to delay premature delivery of your baby. Atosiban is used in adult pregnant women, from week 24 to week 33 of pregnancy.

Atosiban works by making the contractions of your uterus (womb) less strong. It also makes contractions occur less frequently. This occurs because the action of the natural hormone called "oxytocin", the hormone that contracts the uterus (womb), is blocked.

2. What you need to know before Atosiban Altan is administered to you

Do not be given Atosiban Altan

• If you are less than 24 weeks pregnant.
• If you are more than 33 weeks pregnant.
• If your waters have broken (premature rupture of membranes) and you are at or beyond 30 weeks of pregnancy.
• If your baby (fetus) has an abnormal heartbeat.
• If you are experiencing vaginal bleeding and your doctor wants to start delivery so your baby is born immediately.
• If you have a condition called severe pre-eclampsia and your doctor wants to start delivery so your baby is born immediately. Severe pre-eclampsia is when you have very high blood pressure, fluid retention, and/or protein in your urine.
• If you have a condition called "eclampsia," which is similar to severe pre-eclampsia but also includes seizures. This means delivery must begin so your baby is born immediately.
• If your baby has died.
• If you have or may have an infection in the womb (uterus).
• If your placenta is blocking the birth canal.
• If your placenta is detaching from the wall of your womb.
• If you or your baby have other conditions that could make continuing the pregnancy dangerous.
• If you are allergic to atosiban or to any of the other ingredients of this medicine (listed in section 6).

Do not use Atosiban Altan if any of these situations apply to you. If you are unsure, inform your doctor, midwife, or pharmacist before Atosiban Altan is administered to you.

Warnings and precautions

Talk to your doctor, midwife, or pharmacist before being given atosiban:

• If you think your waters have broken (premature rupture of membranes).
• If you have kidney or liver problems.
• If you are between 24 and 27 weeks pregnant.
• If you are carrying more than one baby.
• If you experience contractions again, treatment with atosiban may be repeated up to three more times.
• If your baby is small for the stage of pregnancy.
• If your uterus, after the baby is born, is unable to contract. This may lead to bleeding.
• If you are carrying more than one baby and/or are taking medications that may delay your baby's birth, such as medications used for high blood pressure. This may increase the risk of pulmonary oedema (fluid accumulation in the lungs).

If any of these situations apply to you (or if you are unsure), inform your doctor, midwife, or pharmacist before being given atosiban.

Children and adolescents

Atosiban has not been studied in pregnant women under 18 years of age.

Use of Atosiban Altan with other medicines

Inform your doctor, midwife, or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding a baby, breastfeeding must be discontinued during treatment with atosiban.
