I was put on the Foradil back the end of Aug. when I had a very bad upper respiratory infection and was having extreme wheezing and problems breathing. There was already a warning that if taken wrong it could lead to problems. My doctors directions were to take it for wheezing and or tightness of chest.
I only took it when I really needed it and it helped greatly, but haven't taken it since.
I think if the patient follows the doctors directions, there won't be problems but there is always someone who thinks they know more that the doctor and won't listen, their the ones who will have the problems.
