Can Levoflaxacin Be Taken For Cold And Cough

I have cough and colds with yellow phlegm, woke up to no voice this morning. Can I take Levoflaxacin 500mg once a day for a week? I had no voice 2 months ago, ENT prescribed Klaricid OD, it didn t work, I had Medrol 16mg for 2 weeks, and voice came back after 26 days. I also have Esophagitis gr. D as of last November s endoscopy, and Acid reflux. I am taking Omepron twice a day. Supposed to have Endoscopy today, but will have to postpone. Thank you
