Do you also have a rescue medication? Some for of
albuterol - ProAir, Proventil, Maxair, Ventolin,
Xopenex and a few others. This is a necessity for when you have the shortness of breath (sob) feeling.
Did the hospital tell you what to do about your potassium level? If you do not get that up, you could start having leg cramps. Advair and Symbicort can cause potassium and calcium levels to drop causing cramps.
Take care and feel better.
