I have had an upper respiratory infection that was diagnosed as bronchitis. I had a fever of 100.1 and coughed up green phlegm. I was put on omnicef. Today is the fourth day on the antibiotics. Clearly, I feel better. I am tired, though, and am still coughing up green phlegm. I am concerned that the phlegm is still colored. I have an IgA deficiency, so I have had a lot of these infections. Usually, the phlegm starts to change to white and then clear quickly. I am feeling better, though, so I am confused....Bottom line - Am I getting better or should I contact the doctor?
