[|Human|] Any suggestions for a chronic cough. The cough started 7 weeks ago and became much worse 10 days ago. It is a non-productive, persistent, severe cough.  Promethazine DM, Tussin DM, Flonase, Mucinex and Azithromycin and Zyrtec were prescribed by an urgent care physician 4 days ago and has not had any effect.
[|AI|]  Thanks for posting your query to Chat Doctor. Chronic cough could be allergic or infective in etiology. Ingestion of antibiotics and antiallergic medication is not effective if you have taken without confirm diagnosis .you should first find out the cause of cough and then treat accordingly. I suggest you to investigate for radiological examination of chest, complete blood count, and sputum culture examination and sputum for gram stain and AFB stain . All this test will help you to decide treatment plan as there are different treatment protocol for different condition. You can consult a respiratory and chest physician for complete evaluation of case .hope it will help you
