What is Hemangeol used for?

  • Hemangeol is used to treat proliferating infantile hemangioma.

Before taking Hemangeol, tell your doctor:

  • If your child is allergic to Hemangeol; any part of this medicine; or any other drugs, foods, or substances. Tell the doctor about the allergy and what signs your child had.
  • If your child was born premature and has not reached the corrected age of 5 weeks.
  • If your child weighs less than 4 ½ pounds (2 kilograms).
  • If your child has asthma or has had breathing problems.
  • If your child has any of these health problems: Certain heart problems, a slow heartbeat, or very low blood pressure.
  • If your child has high blood pressure caused by a tumor of the adrenal gland (pheochromocytoma).
  • If your child is at risk for low blood sugar, like if your child is throwing up or not able to take feedings.

This is not a list of all drugs or health problems that interact with this medicine.

Tell the doctor and pharmacist about all of your child's drugs (prescription or OTC, natural products, vitamins) and health problems. You must check to make sure that it is safe for your child to take Hemangeol with all of his/her drugs and health problems. Do not start, stop, or change the dose of any drug your child takes without checking with the doctor.

What are some things I need to know or do while I take Hemangeol?

  • Tell all of your child's health care providers that your child is taking Hemangeol. This includes your child's doctors, nurses, pharmacists, and dentists.
  • Have your child's blood pressure and heart rate checked often.
  • This medicine may hide the signs of low blood sugar. Talk with the doctor.
  • If your child has high blood sugar (diabetes), you will need to watch his/her blood sugar closely.
  • If your child has had a very bad allergic reaction, talk with the doctor. Your child may have a chance of an even worse reaction if your child comes into contact with what caused the allergy. If your child uses epinephrine to treat very bad allergic reactions, talk with the doctor. Epinephrine may not work as well while your child is taking Hemangeol.
  • This medicine may raise the chance of stroke in some children who have very bad problems with the blood vessels in their brain. The risk is higher in children with a large hemangioma that affects the face or head. Talk with the doctor.
  • If you are breast-feeding your child, tell the doctor about all the drugs you are taking. Certain drugs may pass to your child through breast milk and may interact with Hemangeol.
  • Make sure you have the right liquid; there is more than one strength.

How is Hemangeol best taken?

Give Hemangeol as ordered by your child's doctor. Read all information given to you. Follow all instructions closely.

  • Measure liquid doses carefully. Use the measuring device that comes with Hemangeol. If there is none, ask the pharmacist for a device to measure Hemangeol.

  • Give Hemangeol right into your child's mouth. If needed, Hemangeol may be mixed with a little bit of milk or fruit juice and given in a baby's bottle.
  • Give Hemangeol with or right after a feeding.
  • Give doses of Hemangeol at least 9 hours apart.
  • If giving Hemangeol to your child and your child's weight changes, talk with the doctor. The dose of Hemangeol may need to be changed.
  • If your child spits up a dose or if you are not sure your child got all of the drug, do not give another dose. Wait until your child's next dose to give again.
  • Keep giving Hemangeol to your child as you have been told by your child's doctor or other health care provider, even if your child feels well.

What do I do if I miss a dose?

  • Give a missed dose as soon as you think about it.
  • If it is close to the time for your child's next dose, skip the missed dose and go back to your child's normal time.
  • Do not take 2 doses at the same time or extra doses.
