Dry Cough for more than 2 months

Hello Doctor! This query is regarding my father's dry cough. He is 55 years old. Two months ago he started slight coughing. It increased suddenly and the doctor ordered an x-ray. Coughing caused dryness in throat and chest. The report was:- 1. Bony cage and soft tissue appear normal. 2. Cardiac shape and size within normal limits 3. Left Hilar shadow is prominent. 4. No lung parenchymal lesion seen. 5. Both C.P. angles are clear. After this doctor prescribed- Augmentin 625 mg twice a day(for 10 days), Montair 10 mg before bedtime(for 21 days), Pantop D twice a day(for 21 days) and Corex dx syrup thrice a day. The symptoms subsided within 2 days but did not disappear. The doctor ordered a non-contrast HRCT chest. The report was:- 1. The lung parenchyma appears does not reveal significant abnormality. 2. The tracheobronchial tree is normal. 3. No significant mediastinal or hilar lymphadenopathy is seen. The axillae and supraclavicular regions are unremarkable. 4. The pleural spaces are normal. 5. The visualized bones appear unremarkable. 6. The sections through the upper abdomen do not reveal any significant abnormality. Remarks- No lung parenchymal lesion, lymphadenopathy or pleural effusion seen. (CO-RADS-I) After completing 21 days course of all the medicines, the dry cough still persisted. The doctor prescribed Pantop 40 and Montek Lc to be taken for as long as the symptoms persist. He is not asthmatic. How long will it take to resolve the problem and is there anything else that can be done when the coughing increases?

The lung imaging appears to be normal which does not exclude but strongly suggests that the problem is outside the lung.  Common cause of a dry cough at this stage would include taking certain types of blood pressure medications (you need to check this out with your doctor), a chronic post-nasal drip, acid coming up the food pipe (and hence the trial prescription of antacids).  Occult asthma can often also cause a chronic cough.  I would suggest you work with your doctor and note the response to the antacid treatment.  Occult post-nasal drip and use of an antihistamine would be strongly suggested.  You can discuss these possibilities with your doctor.
