Hello.
Thank you for asking at HCM.
I went through your history and would like to make following suggestions for your brother:
1. I would suggest your brother
allergy testing which will help him identify the substances causing symptoms to him and also to know the measures to avoid them.
Based on the allergy testing, an Allergist-Immunologist may prescribe him allergen specific
immunotherapy which gradually improve allergy symptoms by working on immune system.
2. At present, I would suggest him regularly
montelukast and
levocetirizine on daily basis.
3. In general, I would suggest him to avoid exposure to dusts, smokes and air pollution.
Allergies is a big problem in Bangalore because of air pollution.
There are many Allergist-Immunologist in Bangalore. You may consult any of them who is easy to approach with convenient location. There are some institutes like KIMS who have many Allergists-Immunologists with a department of Allergy-Immunology.
Hope above suggestions will be helpful to your brother.
Should you have any further query, please feel free to ask at HCM.
Wish him the best of the health.
Thank you & Regards.
