Without my knowledge,  My son took 10 ml of asthakind dx juinor syrup as he found the bottle on table  on Saturday 21st , and from Sunday 22nd he is getting runny nose and slight cough , no fever . He is active , no other visible side effects . (Note : last week he was on that medicine for cold and dry cough , no mucus, he had taken asthakind dx juinior syrup for a week as per doctors recommendation) I want to know if runny nose n cough is the side effect of that overdose taken by my son ? Or this could be a new infection or allergy ?
