Prostin® VR
Consumer Medicine Information (CMI) summary
The full CMI on the next page has more details. If you are worried about this medicine, speak to your child's doctor.

Why is my child being treated with Prostin VR?

Prostin VR contains the active ingredient alprostadil. Prostin VR is used to keep a blood vessel called the ductus arteriosis open temporarily after your child is born. This helps some children with certain heart defects, for blood to flow around their body until their condition is treated, as usually the blood vessel closes soon after birth.
For more information, see Section 1. Why is my child being treated with Prostin VR? in the full CMI.

What should I know before my child is treated with Prostin VR?

Talk to your doctor if your child has any other medical conditions.
For more information, see Section 2. What should I know before my child is treated with Prostin VR? in the full CMI.

How is Prostin VR given?

Prostin VR should only be used under the supervision of healthcare professionals trained in the care of children, usually in the newborn intensive care unit. Prostin VR is diluted and given by continuous infusion (a slow drip) into the bloodstream.
More instructions can be found in Section 3. How is Prostin VR given? in the full CMI.

What should I know while my child is treated with Prostin VR?

Your child will be closely monitored, including their breathing, heart rate and blood pressure, during treatment.
For more information, see Section 4. What should I know while my child is treated with Prostin VR? in the full CMI.

Consumer Medicine Information (CMI)
This leaflet provides important information about Prostin VR. You should also speak to your doctor or pharmacist if you would like further information or if you have any concerns or questions about Prostin VR.
Where to find information in this leaflet:

Why is my child being treated with Prostin VR?

Prostin VR contains the active ingredient alprostadil.
Prostin VR is used to keep a blood vessel called the ductus arteriosis open temporarily after your child is born. Normally, this blood vessel closes soon after birth. In some children who are born with heart defects, this blood vessel needs to be kept open for a longer time so that enough blood can reach the rest of the body. Once the child's heart defect is treated, Prostin VR is usually no longer needed and the blood vessel should close.
Your doctor may prescribe Prostin VR for other reasons. Ask your doctor if you have any questions about why Prostin VR has been prescribed for your child.

What should I know before my child is treated with Prostin VR?

Some information is given below. Talk to your doctor if you have any concerns or questions about your child's treatment.

Prostin VR should not be given in:

Children with the following medical conditions:
a blue appearance of the skin, lips and nails due to poor blood flow through the lungs
abnormal or unusual blood flow between the lungs and the heart

Check with your doctor if:

Your child has had any medical conditions, especially the following:
history of bleeding tendencies
a breathing problem where the lungs have difficulty holding in air (respiratory distress syndrome).
During treatment, your child should be closely monitored for certain side effects. See additional information under Section 5. Are there any side effects?
