Hello,
Thank you for asking at HCM.
I went through your son's history and would like to make suggestions for him as follows:
1. Were I treating him, I would add
montelukast to his treatment (
levocetirizine and budesal respules).
2. Please give him
levolin only upon doctor's suggestion as it may not work in all types of coughs. So I will suggest you to get him examined by doctor and use appropriate cough syrup as suggested by doctor.
3. I would also like to mention here that budesal takes time to be effective and also it needs to be given for long duration. It is not an emergency medication for cough. So please have patience till it becomes effective (usually, 7-14 days).
4. In general, please avoid exposure to dusts, smokes and air pollution to your son.
Hope above suggestions will be helpful to your son.
Should you have any further query, please feel free to ask at HCM.
Wish your son the best of the health and a very good recovery.
Thank you & Regards.
