Adrenergic bronchodilators are medicines that stimulate the nerves in many parts of the body, causing different effects.
Because these medicines open up the bronchial tubes (air passages) of the lungs, they are used to treat the symptoms of asthma, bronchitis, emphysema, and other lung diseases. They relieve cough, wheezing, shortness of breath, and troubled breathing by increasing the flow of air through the bronchial tubes.
Epinephrine injection (including the auto-injector but not the sterile suspension) is used in the emergency treatment of allergic reactions to insect stings, medicines, foods, or other substances. It relieves skin rash, hives, and itching; wheezing; and swelling of the lips, eyelids, tongue, and inside of the nose.
These medicines may be also used for other conditions as determined by your doctor.
Ephedrine capsules are available without a prescription. However, check with your doctor before taking ephedrine.
All of the other adrenergic bronchodilators are available only with your doctor's prescription.
Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although these uses are not included in product labeling, some of the adrenergic bronchodilators are used in certain patients with the following medical conditions:
- Bleeding of gums and teeth during dental procedures (epinephrine)
- Hyperkalemia (too much potassium in the blood) in children (albuterol)
- Premature labor (terbutaline)
- Priapism (prolonged abnormal erection of penis) (epinephrine)
