Hello Doctor, my daughter is having cold from past 30 days .from day I have started medication montek lc kid for about 10 days. No result .then after 4 days I have used allegra120 syrup for about one week. Still runny nose and cough is there then we visited the physician and I have used rekof for about one week. But still cough and runny nose is there. Doc has told lungs are clear and no sign of infection. She is getting cold almost once in a month. Every time I will use montek lc kid and it will be cured in 10 days. But this why it was not going off even though I am using medicine. Please let me know.
