Hi My Mother Is Being Treated For Bronchitis And Been

Hi my mother is being treated for bronchitis and been using ceclor 500mg 3 times a day from the last 7 days. The doctor also prescribed clinell and ventoline nebules and she was nebulised for 3 days with the nebules after that we have continued with ceclor however she is still coughing a lot and although the severity has decreased somewhat she still coughs a lot and a weezing noise can be heard when she breathes. What is the advise? Change the antibiotic or do nebulization a bit more? She is also taking ventoline syrup thrice a day.

Thanks
