Levalbuterol is a medication used to treat breathing problems caused by conditions like asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, making it easier to breathe. Levalbuterol is often prescribed as an inhaler or nebulizer solution. This medication is a type of bronchodilator, specifically a selective beta-2 adrenergic agonist. It is known for having fewer side effects compared to other similar medications, which can be beneficial for patients who may be sensitive to those effects. Always follow a healthcare provider's instructions when using levalbuterol.
