Brief Answer:
yes but not the greatest choice...

Detailed Answer:
Hello,

cephalexin can be used for urinary tract infections caused by susceptible bacteria (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and others) but it's not a common choice among physicians. 500mg (or higher when necessary) orally every 12 hours is the right dosage.

Antibiotic choice for a urinary tract infection depends on whether it's an upper or lower tract infection and other factors from the patient's history like recent exposure to antibiotics, allergies, culture results, etc. Quinolones are top choices regarding efficiency but they're better left for the more serious cases. For lower tract infections nitrofurantoin is a great choice for most patients. Cephalosporins can - of course - be used for both upper and lower tract infections.

I hope you find my comments helpful!
Kind Regards!
