How does this medication work? What will it do for me?
Alprostadil, also known as prostaglandin E1, belongs to a class of medications known as vasodilators. It is used to treat babies with certain types of congenital heart defects. It keeps the ductus arteriosus (a passageway in the heart) open until surgery can be done.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why your baby is being given this medication, speak to your doctor.
What form(s) does this medication come in?
Each 1 mL ampule contains alprostadil 500 µg in anhydrous ethanol.
How should I use this medication?
The recommended initial dosage of alprostadil is calculated by your doctor based on body weight. When the desired effect on the ductus arteriosus (a passageway in your baby's heart) is achieved, the infusion rate is usually decreased to the lowest possible dose while still maintaining the desired effect on the ductus arteriosus.
Alprostadil is usually given through a continuous intravenous infusion into a vein by a health care professional in a hospital setting. It can also be given into an artery at the opening of the ductus arteriosus.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. Your doctor may have recommended a different dose from the one listed here.
Store this medication in the refrigerator at 2°C to 8°C. Once the medication has been prepared by dilution, it must be used within 24 hours, after which it must be discarded. Protect from light and keep out of reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
Who should NOT take this medication?
Alprostadil should not be used by anyone who:
- is allergic to alprostadil or to any of the ingredients of the medication
- has certain heart or lung conditions which, in their doctor's judgment, would make it dangerous for them to use this medication
