Hi,,Yes you can use keflex

I am not a Doctor.

Treatment of Strep Throat

The cephalosporin antibiotics such as cephalexin (Keflex, Keftabs, Biocef) and cefadroxil (Duricef)are about three times more effective and three times less likely to fail --in eradicating strep than penicillin.

I hope I have been of some help.
