Vasodilators are effective in relaxing the blood vessels, which allows blood to get to the tissues of the body more easily.1
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine your child takes. Side effects are also listed in the information that comes with the medicine.
Here are some important things to think about:
- 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.
Call 911 or other emergency services right away if your child has:
- Trouble breathing.
- Swelling of the face, lips, tongue, or throat.
Call your doctor right away if your child:
- Has hives.
- Becomes dizzy or lightheaded, or if your child faints.
Common side effects of this medicine include:
- Dry cough.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
