Question: how do you know if your baby is allergic to amoxicillin?
Answer: If your child develops hives, which are raised, itchy, white or red bumps on the skin that appear after one or two doses of the medicine, they may be allergic to penicillin. If you notice your child has hives after taking amoxicillin, you should call your doctor right away, as the allergic reaction could get worse.
