Would Cephalexin Work for Strep Throat?

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

How much cephalexin should I take for strep throat?

Cephalexin dosage for adults

Streptococcal pharyngitis (strep throat): 500 mg by mouth every 12 hours for ten days. Uncomplicated urinary tract infection (not a first-line drug for this indication): 500 mg by mouth every 12 hours for 3 to 7 days or 250 mg by mouth every 6 hours for 3 to 7 days.

Can cephalexin be used to treat strep throat?

For people with a penicillin allergy, treat Strep throat with either a narrow-spectrum cephalosporin (such as cephalexin or cefadroxil), clindamycin, azithromycin, or clarithromycin.
