If you suffer from respiratory problems, such as asthma or chronic obstructive pulmonary disease, your healthcare provider may prescribe Xopenex® (levalbuterol hydrochloride). The medication works by opening up the airways to allow more air to enter the lungs. It comes in a liquid form that is used in a nebulizer. As with any medication, it is possible to take too much Xopenex. Symptoms of a possible overdose include seizures, a fast heart rate, or chest pain.
