How It Works
Bronchodilators relax the muscles in the airways of the lungs. This
enlarges (dilates) the airways and makes it easier for you to breathe.
Bronchodilators may also help you cough up
mucus. When they are used to treat
cystic fibrosis, bronchodilators are usually given
through a
nebulizer or with an
inhaler. They are rarely taken as a pill or given as
an injection.
Why It Is Used
Bronchodilators are used to treat many lung diseases, including
cystic fibrosis.
To minimize certain side effects, bronchodilators are often used
along with inhaled
antibiotics.
How Well It Works
Some people who have cystic fibrosis breathe much more easily
while using bronchodilators. Other people do not notice any benefits.
Bronchodilators work better on people who have inflamed, narrow
airways.
Side Effects
These medicines are more likely to cause side effects when they are
taken as a pill or through an injection than when they are inhaled. Side
effects can include:
- Anxiety.
- Muscle
tremors.
- Increased heart rate.
In addition, each type of bronchodilator may have its own
additional side effects.
The U.S. Food and Drug Administration (FDA) has reported that
salmeterol may make breathing more difficult. If your wheezing gets worse after
taking this medicine, call your health professional right away.
See Drug Reference for a full list of side effects. (Drug Reference
is not available in all systems.)
What To Think About
Inhalation is the best way to use bronchodilator medicines. Oral
and injected methods have more side effects and are usually given only to
people who cannot tolerate inhaling the medicine.
When taking certain bronchodilators, consider the following:
- Bronchodilators may cause fewer side effects if
they are used before a dose of inhaled antibiotics.
- It is very important to take each medicine at the right time and
in the right order.
- Salmeterol should not be used in place of the
other bronchodilators listed above. It is important to follow your doctor's or
pharmacist's instructions for using bronchodilators.
- Salmeterol
should not be used instead of an inhaled anti-inflammatory medicine (such as a
corticosteroid, cromolyn [Intal], or nedocromil [Tilade]).
- Over-the-counter bronchodilators (such as Primatene)
should not be used without first talking to your doctor. If you are using one
of these products, talk with your doctor about your symptoms.
