my son is 5 years old (weight 47 lbs) and had a allergic reation with hives and welts at 5 am this morning and we gave him bendryal and it subsided the problem , it re- occured in 7 hours later in different spots. he recently ahd to take a duration of treatment each day for the past 3 motnhst with his nebulizer with the "Pulmocort" steroid, since he had a bad bout with allegies and asthma., per his allegist doctors orders. If i gave him his nebulizer with the steroid( pulmocort will that help his problem? ( he does take singular chewable every morning as a treatment also. Does the steroid have to be taken orally to work??....for it to do any good for a allegic reation to make it really subside ?? he is going to his regular doctor first thing in the morning. We actually took him to the medi center early this morning and they said just do bendral. It did go away for 7 hours and now is re-occuring.. i am also taking him to the allegist on thursday to see if it isa food allegy. pls advise thank you

Hello, Thank you for asking at Chat Doctor. I went through your sons 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. Ben Chat Doctor.  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 Chat Doctor. Wish your son the best of the health ahead. Thank you & Regards.
