Thanks for your question on Healthcare Magic. I can understand your concern. Better not to start any drug directly. She is having chronic cough and cold not improving with routine antibiotics. So we should definitely find out cause for this. So consult pediatrician and get done clinical examination of respiratory system and chest x ray. Possibility of lung infection or allergic asthma is more likely in her case. She may need higher antibiotics and anti allergic (montelukast) drug on the basis of reports. So don t start anymore drugs without proper diagnosis. Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
