My daughter has been on keflex for staph with hives for 2 days but the hives continue to grow and she still has a fever. should she see a doctor again?

Yes, immediately: Hives are a sign of allergy and your daughter should see her doctor immediately to change the medication. If she develops even the slightest breathing problem, take her to an emergency room right away.

Call the Office : Keflex is in a class of medications called cephalosporins, a cousin to penicillin, and can cause a rash. The fever can be caused by either the infection for which she is taking the antibiotic, as well as the antibiotic itself in the setting of a mild reaction. I would call your doctor to let them know about the suspected reaction and let them advise you directly.
