Asthma Home > Advair 115/21

Of the three dosages available for the Advair® (fluticasone and salmeterol) HFA inhaler, the 115/21 dosage is in the middle of the range. It contains 120 inhalations with 115 mcg fluticasone and 21 mcg salmeterol per inhalation. This medication comes in a traditional, metered-dose inhaler, known as the Advair HFA inhaler. The medication is inhaled using the inhaler twice a day (typically), with about 12 hours between doses.
The Advair HFA inhaler is only approved for preventing airway spasms in people who have asthma (it is not approved for treating people who have chronic obstructive pulmonary disease, or COPD).
The recommended Advair HFA inhaler dose for asthma depends on the dose of other asthma medications taken in the past, varying from two inhalations of Advair HFA 45/21 twice daily to two inhalations of Advair HFA 230/21 twice daily.
