Thanks for the query
You are absolutely right that coughing is a protective response. That's why cough suppresent are not recommended in children. After any infection whether it is viral or bacterial cough takes time to subside, even when all other symptoms subside. I hope your child has been immunised for pertussis
. Give her
syp. (100mg/5 ml ) 5 ml once a day empty stomach for 3 days , ambrodil-s syp 2.5 ml thrice a day for 5-7 days and Zinc syp. 5 ml a day for 14 days.
