Breo is a brand of inhaler used to treat asthma and chronic obstructive pulmonary disease (COPD). It contains two active ingredients: fluticasone, a corticosteroid that reduces inflammation, and vilanterol, a long-acting bronchodilator that helps open the airways. Breo is typically prescribed for daily use to help manage symptoms and improve lung function. This medication is available in a dry powder inhaler form, making it easy for patients to use. It is important for users to follow their healthcare provider's instructions regarding dosage and frequency to ensure effective treatment and minimize potential side effects.
