Testing for Allergy to Antibiotic
My son, who is allergic to peanuts and eggs, was prescribed antiobiotics (amoxicillen) yesterday for the first time. (Yes, except for the allergies, he's been very healthy!) After the first dose, he took off his socks and started scratching his feet. After the second, he started itching all over his body. I noticed little white bumps, like tiny mosquito bites, all over him. About 10pm, I finally put 2 and 2 together (allergy- duh!), gave him Benadryl and he calmed down and was able to sleep.
My question is: are antibiotics not part of the routine scratch tests performed to determine allergies? When he was 2, we took him to a pediatric allergist who tested him for 80 different allergens. She said the only things he was allergic to were peanuts and eggs. I called her office today to ask about this, but they're not open.
Either antibiotics/penicillen weren't included in his original testing, or he has developed this allergy post-testing. Any light on the subject would be appreciated.
