<s>[INST] My 3 year old was stung by a bee on the foot yesterday. The whole foot swelled overnight. He vomited once, woke with a fever and hives. The fever is controlled with Tylenol, the swelling reduces with benadryl and cold compress but the hives continue to appear. He has not had any difficulty breathing. Should we be worried? [/INST] Hi, By what you quote it should be an urticarial or a simple skin allergy. You can use Hydroxyzine at 1-2mg/kg/dose every 6th to 8th hourly for 7-10 days. Most important thing to be remembered is that it has a propensity to recur (called as second crop) within 10-14 days. If this happens, you can start using the same medicine but I suggest you get the kid evaluated with your paediatrician. Hope I have answered your query. Let me know if I can assist you further.
