Hello. Thank you for asking at HCM. I went through your son s history. I would like ask a few more questions like - Since what age has he had these problems? What is the frequency of his symptoms? What are the worst seasons for him? Has he ever had breathing difficulty? However, from your given history, I would like to make following suggestions for your son: 1. If Alaspan or Cetirizine are making him drowsy, I would suggest him Fexofenadine or Ebastine, which may cause less sedation. As he has severe symptoms, I would also add regular montelukast, were I treating him. Combination of both above drugs will help in both nose and eye symptoms as well as reducing wheezing episodes. 2. In addition to above, when he has wheezing, I would suggest him to use salbutamol or levosalbutamol inhaler. It is not to be used regularly, it is only to be used when he has an wheezing episode. 3. Personally I would suggest him allergy testing, which will help identify his allergies and also measures to avoid them. 4. I would suggest him to avoid exposure to dusts, smokes and air pollution as much as possible. Also, regular breathing exercises and a healthy diet rich in vitamins and minerals (e.g., adequate amounts of green leafy vegetables, fruits, sprouts, etc) will help him in a long run. Hope above suggestions will be helpful to him. Wish him the best of the health. Should you have any further query, please feel free to ask at HCM. Thank you & Regards.
