 Air Supra is the first ever dual action rescue inhaler that treats your asthma symptoms and helps prevent attacks. Air Supra is the only rescue FDA approved to do both. Air Supra is an as-needed rescue inhaler and should not be used as a maintenance treatment for asthma. Get medical help right away if your breathing does not improve, continues to worsen, or for serious allergic reactions. Using Air Supra more than prescribed could be life-threatening. Serious side effects include heart problems, increased risk of thrush, or infections.
