Hi, I had gone through your question and understand your concerns. Your daughter appears to be suffering from allergic cough but if cough is very intense and prolonged pertussis also needs to be ruled out , is there wheezing or whistle like sound during breathing . You have not mentioned duration of cough , a few days cough may be due to simple viral infection with post infection hypersensitivity . I suggest you get your examined by a doctor preferably a paediatrician to know cause of cough , get basic investigations done if required , and please do not self medicate . Asthalin is going to help only if there is component of allergy or congestion is there. In case of possibility of pertussis a course of macrolide group of antibiotics like azithromycin can be given after consulting your doctor. So my suggestion to you is get proper evaluation instead of trial of medicines. Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. Take care. • DISCLAIMER: - All the information provided here is for information purpose only , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
