My daughter started 5 day Prednisone burst(on 2nd day) and Zyvox (also second day). She is coughing more today than when she started! Coughed up some clear mucus, I'm guessing the Prednisone opened her up more so she could get the mucus out? I thought the prednisone would tamp down her cough. Waiting on her culture, won't be ready til next week; If she keeps this up tomorrow I may call to see if a prelimary is back, way too soon for sensitivities. Thoughts?
