###Human: Levosure has not relieved me of my cough. What should I do? ###Assistant: Hello. The symptoms you provided are typical findings of this season. If you have a productive cough which is yellowish or greenish, it indicates a bacterial infection of the respiratory tract. It could be a case of bronchitis and Levofloxacin should work. Consult your specialist doctor, discuss with him or her and with their consent take the medicines. If not, you could get a culture and sensitivity test of the sputum and switch to another antibiotic according to the report. However, if you have a dry cough, no fever or purulent sputum, it could also be a post-infectious cough or a cough associated with postnasal drip. Also, if you smoke, it can make your cough worse. If your symptoms do not resolve with medication, you should get a chest x-ray done. For more information consult a family physician online -->
