Key takeaways
Fluticasone/salmeterol (Advair) and budesonide (Pulmicort Flexhaler) are both inhaled medications used for the maintenance treatment of asthma. However, they belong to different medication classes. Advair is a combination of an inhaled corticosteroid (ICS) and a long-acting beta agonist (LABA), while Pulmicort Flexhaler contains only an ICS. Advair is also approved for chronic obstructive pulmonary disease (COPD) in its Diskus form, whereas Pulmicort Flexhaler is not. Advair is available in multiple strengths and is typically taken as 1 to 2 puffs twice daily, while Pulmicort Flexhaler comes in two strengths and is taken twice daily as well. Common side effects of Advair include upper respiratory infections and sore throat, while Pulmicort Flexhaler may cause symptoms of the common cold. Both medications can cause oral thrush, so it's important to rinse your mouth after use.
