Hi doctor,

This is about my son who is 3.5 years old. He started having an allergic cough before seven months. The frequency was once in a month. The doctor said he is allergic to dust and humid weather and prescribed Romilast. He was fine. But, from the 1st of last month, he is having the allergic cough once again. As previous times, I went to doctor and he prescribed combination of Romilast, XL90 and Azithral. But, he is still having cough, though it is less and a very few times in a day. A few things for which I want to consult with you are his cough is not completely going away. He has lost 1.5 kg weight and he does not eat as previous and seriously look so lean. He weighed 14.5 kg last month. Though he is suffering from cough and cold and not eating properly, but still he is active. He goes to school every day. We have noticed, if he sweats heavily or goes through dust within a day he will start sneezing and then coughing. Please help us.



Welcome to

I understand your concern for your child.

  • Most probably this is allergic cough only, which is most common in kids these days. It is really great that you at least know that dust is the culprit. Many parents cannot even trace out the allergy causing thing in their child.
  • My first advice is to avoid allergen exposure. Use mask outside and avoid dust by keeping home dust-free. Old dust at home causes much more problem due to dust mites in it, which cause allergy.
  • For these episodes Romilast (Montelukast), Ascoril (Terbutaline), etc., you are already taking and these are only required. At times it may take long time to resolve. But, if only a mild cough for a few times a day as you said, then there is no need to worry much.
  • But, my concern is not gaining weight and we need to investigate. Have you ever gone for any investigation?
  • Please let me know the following details. For how long he is losing weight? Is there any history of chronic cough in family or neighborhood like tuberculosis?

Investigations to be done:

1. Complete blood count.
2. Absolute eosinophil count.
3. Chest x-ray.
4. Mantoux test.

Treatment plan:

I suggest tablet Zentel (Albendazole) only today before sleeping. Consult your doctor, discuss with him or her and take the medicine with consent.

Thank you doctor,

I am really worried about my kid's health. He lost 1.5 kg since one month. There is no history of chronic cough in my family or neighborhood. My husband and my brother-in-law had childhood asthma till they were 6 to 7 years old. Though I do not know whether this will be useful information for you, but still I am pointing out some information. I am not sure whether the childhood health is hereditary, but as per my mother-in-law, my husband had the same body structure in childhood. I will take him for the tests as soon as possible.



Welcome back to

  • Fine, it means the allergy in the family called atopy in medical science. This further goes in favor of allergy only.
  • Asthma is also an allergic condition with symptoms like difficulty in breathing, chest tightness and cough.
  • I would ask you to improve his nutrition. Give him a good amount of protein in the diet as our diet is usually less in proteins.
  • Please do not worry, if he is active and otherwise well.
  • I believe nothing else than allergic cough would come and which just like his dad would go away. Also, keep a track of his weight and height.
