It sounds like an allergic response, so it would be wise to avoid the penicillins, and I would also ask for an
allergy referral, because if she has
a true
allergy to an antibiotic, she should have
a medic alert bracelet. If you are seeing swelling in the lips, it is possible that she could have an anaphylactic reaction in the future.
It's probably taking some time for the strep to clear because her first doses of amox were not effective....
