Hi I am experiencing a productive painful cough with yellow green sputum. This began just two days ago. I went to my PCP yesterday who prescribed LEVAQUIN 500 1 pill qd for 7 days. Also, he prescribed symbicort for use BID. His instructions were if I do not improve to begin a PREDNISOLONE pack, which he provided. I am a non smoker, no fever, but I do have body aches. I hate to take steroids. How long do you think I should give this course of therapy before oving on to the steroids if I do not improve?
