Hi, I had gone through your question and understand your concerns.
You have not mentioned which
ascoril you are using , is it ascoril + expectorant , Ascoril-D or Ascoril-C syrup .
It is safe to use Ascoril in prescribed doses.
Based on little history provided by you , your child may be suffering
allergic cough ( nighttime ) a trial of
Montelukast and Bambuterol or inhalation bronco-dilator with nhalation
steroid can be tried after discussing with your doctor to see the response .
Hope this answers your question. If you have additional questions then please do not hesitate in writing to us.
Wishing your son good health.
