How It Works

Vasodilators relax the muscle around blood vessels. This allows blood vessels to expand, letting blood flow more easily through the vessels.

Why It Is Used

Children with congenital heart defects often have heart failure. Vasodilator medicines decrease blood pressure by relaxing blood vessels, allowing more blood to flow through the vessels.

How Well It Works

Vasodilators are effective in relaxing the blood vessels, which allows blood to get to the tissues of the body more easily.1

  • Usually the benefits of the medicine are more important than any minor side effects.
  • Side effects may go away after your child takes the medicine for a while.
  • If side effects still bother your child and you wonder if he or she should keep taking the medicine, call your doctor. He or she may be able to lower the dose or change the medicine. Do not suddenly have your child quit taking the medicine unless your doctor says to.
