How quickly does cephalexin cure a UTI?

Cephalexin typically begins to alleviate symptoms of a urinary tract infection (UTI) within a couple of days of starting treatment. However, it usually takes the full course of antibiotics, which is often 7 to 14 days, to completely eradicate the infection. It's important to finish the prescribed course even if symptoms improve earlier to ensure the infection is fully cleared. Always consult a healthcare professional for specific advice and treatment.
