I was placed on Fostair in the last fortnight and one unusual thing that happened a few days later was a vicious coughing fit out on the street. When the fit had emptied my lungs, the airway closed off and I couldn't breathe - very alarming. The GP said it was actually an asthma attack although the Fostair had all my wheezing and tightness under control at the time.
Fostair wakes me up at night, makes me need to drink more water and perhaps might be affecting my blood pressure - the beclometasone has caused me to have fainting in previous years and this has happened this last Monday (the coughing fit was the previous Friday.) I won't use more than two puffs daily.
