No, Advair shouldn’t be used during a COPD or asthma flare-up (sudden worsening of your symptoms). It also shouldn’t be used in an emergency (severe flare-up). Advair doesn’t work quickly enough to provide relief during these situations. You should always carry a rescue inhaler to give you immediate relief.
See the “Advair use with other drugs” section for more details about rescue inhalers. Also, talk with your doctor about what to do if your asthma or COPD symptoms suddenly get worse.
