Does Zifi 100 Syrup Help In Treating Cough Of 3 Year Old Child?

Hi, My kid is 3 year old and she has cough for almost 6-7 days now, once she starts coughing it goes on for almost 10-15 seconds, we showed to a child specialist and he suggested to give bronchotone for 5 days, but no response and the condition is not good now, then he prescribed zifi 100 syrup and grillinctus which we have started yesterday onwards. Kindly suggest if we are on right track
