My daughter aged about 11 years has allergic cough for the last 2-3 months. I tried homeopathy, but it only aggravated her condition. When she was 05 years, she had this allergic cough and during that time I had to run to the hospitals to nebulize her. Later on with the growing of age she get all fine, but the situation has again returned, but the intensity is low, I don t have to nebulize her, but the cough remains. Only when I give her Montair LC kid, her cough gets over, otherwise, she keeps coughing. What should I do and how long should I give her Montain LC kid ??
