It is not uncommon for people to develope allergies toward the end of a course of antibiotics. Your story is fairly typical. Your daughter has had a pretty bad allergic reaction to penicillin and should never get penicillin or Amoxicillin ever again.

Hives with penicillin occurs in about 2% of people. If your daughter only had hives and no other symptoms, it could be allergy or it could be hives as a reaction to the infection. However, with the eye swelling, i lean more toward a true allergy. If a definitive answer is required, skin tests for penicillin and it's derivatives can be performed by an allergist.
