Advair is a brand name for a combination inhaler medication used to treat asthma and chronic obstructive pulmonary disease (COPD). It contains two active ingredients: fluticasone propionate, a steroid that helps reduce inflammation in the airways, and salmeterol xinafoate, a long-acting bronchodilator that helps relax the muscles in the airways, making it easier to breathe.

Advair is usually prescribed for people with moderate to severe asthma or COPD, who require both a steroid and a bronchodilator to control their symptoms. The medication is available in different strengths, depending on the severity of the condition, and is usually taken twice a day by inhalation.

As with any medication, there are potential side effects associated with Advair. These can include headaches, throat irritation, hoarseness, coughing, and increased risk of pneumonia or other respiratory infections. It is important to talk to your doctor about the risks and benefits of taking Advair, and to follow the instructions for use carefully to minimize the risk of side effects.
