Amanda, a 3-year old child, is brought in to your walk-in clinic to be treated for strep throat. The physician orders Amoxicillin powder for suspension.

You ask the child’s mother if the child has any allergies to antibiotics, and the mother says she does not. You then administer the first dose to the child.

Twenty minutes later, the Mother points out several hives the child just developed. You then notice the child itching and coughing, which quickly turns into shortness of breath.
