In brief: Generally ok

I think what you are asking is if you had an allergic reaction to one of these is it safe to take the other. It turns out that although cephalosporins like Cefzil (cefprozil) are related to penicillins the evidence for cross reactivity was inadequately substantiated.
If you had a very severe reaction you could be skin tested for allergy to penicillin.
