Cephalexin

Alternative Names: Keflex

Cephalexin is a first-generation cephalosporin antibiotic sometimes used to treat uncomplicated urinary tract infections caused by susceptible bacteria, such as E. coli, Klebsiella, or Proteus species. It works by interfering with bacterial cell wall formation, leading to bacterial death. Cephalexin is generally well tolerated and may be prescribed when common first-line options (such as nitrofurantoin or TMP-SMX) are not suitable due to allergies, resistance patterns, or side-effect concerns. Typical side effects include gastrointestinal upset and, less commonly, rash or allergic reactions.

Cephalexin is often considered a first-line option for uncomplicated urinary tract infections and is generally effective against common uropathogens but lately it has had developing resistance.. It’s usually well tolerated and easy to dose, making it a convenient choice for many patients. However, those with a known penicillin allergy should use caution, as there is potential cross-reactivity and an alternative antibiotic may be more appropriate.
