Suggest treatment for persistent dry cough
Patient: my mom-in-law is suffering from persistent dry  cough from last 5 months.all x rays , broncoscopy,ct scan of the chest have been done and the reports are negative . she is now taking cardiozol-paracodina which gives her temporaray relief.if she stops the cough starts again.kindly give advice Doctor: Thanks for your question on Health Care Magic. I can understand your mother in law's situation and problem. No need to worry for major Pulmonary disease because her CT scan and bronchoscopy are normal. Sometimes small airway disease like bronchitis or bronchiolitis can cause dry cough. These are functional diseases and so can not be picked up by imagining studies or scopy.For this, she needs to get done PFT (Pulmonary Function Test). If it shows obstructive airway defect than her cough is mostly due to bronchitis or bronchiolitis. And then she will improve with inhaled corticosteroid and inhaled bronchodilators. So get done PFT first. Hope I have solved your query. Wishing good health to your mother in law. Thanks.
