Advair Diskus: Uses, Dosage, Side Effects, Warnings, and Precautions

What Is Advair Diskus?

Advair Diskus is a prescription combination inhaler used for the long-term treatment of asthma and chronic obstructive pulmonary disease (COPD). It contains two active ingredients: fluticasone propionate, an inhaled corticosteroid (ICS) that reduces inflammation in the airways, and salmeterol, a long-acting beta2-adrenergic agonist (LABA) that relaxes the muscles around the airways to improve breathing. It is intended for regular maintenance therapy and is not a rescue inhaler for sudden breathing problems.
