My 11 week old was prescribed penicillin for an infection.....?

4 days into treatment he started to show signs of a severe allergic reaction. Luckily we were already on dexamthasone Intensol (oral steroid) to help with some airway swelling and inflammation. Unfortunately he is too young for Benedryl and the symptoms from the reaction are slowly improving but we still have a very prominent hives and rash. It has been about 8 days since we discontinued treatment and since he is so young he could only take the dexamthasone Intensol for 5 days due to the increase of more bacterial infections with prolonged use. I was wondering how long the rash/hives should last, I feel so sorry for the little guy!! Do you know anything that could help this?

    The common rash reaction can last a bit over a week but itching usually stops within a couple of days. Hope your little guy feels better soon!

    Hives and rash isn't fatal. It's caused by overexcited antibodies; just let the body fix itself. Benadryl and other anti-allergens will fake out the antibodies but they also have some side effects (lulling other body defenses to "sleep"). It might be a couple days, or just an hour. If it lasts about six or seven days, see a Dr. but chances are, they have to let the baby's body fix itself.
