What is an albuterol inhaler used for?

An albuterol inhaler is used to prevent or treat individuals with reversible obstructive airway disease that are experiencing a bronchospasm, according to Drugs.com. It can also be used to prevent bronchospasm caused by exercise. Patients younger than four years old should not use albuterol inhalers.

Albuterol is an adrenergic bronchodilator and works to open the bronchial tubes and increase air flow to the lungs, according to Mayo Clinic. When inhaled through the mouth, adrenergic bronchodilators help alleviate wheezing, shortness of breath, cough and trouble breathing. Side effects of albuterol inhalers include trembling or shakiness of the arms, hands, feet or legs; cough; difficulty swallowing; and fast or pounding heartbeat, states Drugs.com. If side effects occur, patients should consult a doctor.
