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.
Pulmicort helps in respiratory allergies, especially asthma. It will not help in hives.
2. For hives, I would suggest you to give him antihistamine like
fexofenadine,
levocetirizine or cetirizine.
Benadryl also is an antihistamine, only thing is it causes more sedation.
As effects of antihistamine wanes after some hours, one may need to give them repeatedly for 3-5 days.
3. Oral
steroids help hives, but due to lots of possible side effects, I would not suggest you to give him oral steroids for hives. They should be given only for severe hives and that only on prescription of a doctor.
4. I would agree with you that I would also suggest him allergy testing for food allergies. If he is allergic to food, that particular food should be avoided.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish your son the best of the health ahead.
Thank you & Regards.
