<s>[INST] I have a deep cough that raises clear mucous. I have been xrayed and know there is no pneumonia or bronchitis. I do not have a history of asthma. My doc prescribed a week of prednisone which I have just started. But I wonder if Benzonatate might be helpful for this? [/INST] Hi, Benzonatate is a cough suppressant drug. Prednisone is an oral corticosteroid. Prednisone is effective only if it is an allergic etiology related cough. Since you don't have asthma or bronchitis, I don't think your cough will improve with prednisone. Better to take Benzonatate first as it is cough suppressant. It will definitely reduce your cough. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Kaushal Bhavsar, Pulmonologist </s>
