Levalbuterol is a short-acting bronchodilator used to treat symptoms of asthma and chronic obstructive pulmonary disease (COPD).  Those symptoms include a feeling of tightness in the chest, shortness of breath, wheezing, and trouble breathing. It is available as a solution for nebulizer machines as well as a metered-dose inhaler under the trade names, Xopenex and Xopenex HFA.

Levalbuterol, in its most popular form, is inhaled from a pressurized canister to treat symptoms of asthma attacks and problems associated with chronic breathing conditions. It works by stimulating the narrowing of the bronchial passages in the lungs, thus making it easier to breathe.

Often compared to the popularly prescribed albuterol, levalbuterol and Xopenex are popular choices of physicians for patients with certain arrhythmias because it is believed levalbuterol can produce fewer side effects like hyperactivity and jitteriness.

A doctor will give correct dosage information for children and adults.

Side effects of levalbuterol (Xopenex and Xopenex HFA) can include dizziness, dry mouth, nervousness, sore throat, tremor, and runny or stuffy nose. Serious side effects include irregular heartbeat, chest pain, fever, hives, and swelling.

Overdosing on levalbuterol can be fatal.
