Thanks for your question on Healthcare Magic. I can understand your concern. In my opinion, you should consult pediatrician because in children it is not advisable to give drugs without proper diagnosis. Your daughter is having chronic cough (cough for more than 2 weeks) which is not getting better with routine cough medicines. So we should rule out lung infection and bronchitis in her case. So get done clinical examination of respiratory system and chest x ray. She may need antibiotic and inhaled treatment (inhaled bronchodilators or inhaled corticosteroid). Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
