My father has dry cough from one month but still he wouldn't be get out from cough. We consult local doctor but he said take general cough syrup for one week then we used it two weeks but dad has not free from it and we consult another doctor he gave medication which are (tab-moxif 400gm, tab-zincold, reswars sryp, brozeet ls, cap-foracot 200mcg) we used course of one week. while using it seems like dad felt ok somewhat free from cough and course has been completed but after 4 days he started coughing again like starting stage. Is there any other way to get out from cough??? Note: Dad coughing whole day but not much and  while sleeping he won't get cough.
