Formoterol (Formoterol fumarate) — Uses, Dosage, Side Effects & Safety

Drug class: Long-acting beta2-adrenergic agonist (LABA)

Overview

Formoterol is a long-acting bronchodilator used to help control symptoms of asthma and chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. It works by relaxing the muscles in the airways, making it easier to breathe and helping to prevent symptoms such as wheezing, coughing, chest tightness, and shortness of breath. Formoterol is not a rescue medication and should not be used to treat sudden breathing problems. Instead, it is used regularly to help keep airways open and prevent asthma attacks or COPD flare-ups. It is often prescribed in combination with inhaled corticosteroids for asthma. Key points: Always use Formoterol exactly as prescribed, and continue using your other inhalers as directed. Do not stop using Formoterol suddenly without consulting your healthcare provider.
