Used it, in conjunction with a salmeterol reliever, to get off steroids. Inceased suddeness and severity of attacks, twice having to be ambulance driven to the ER. Absolutely unable to shed the 60 pounds put on with steroids- despite having been a healthy weight for 35 years, before taking these drugs. Have now given up all but the occaisional use of Salmeterol reliever, all symptoms gone.
