Unfortunately, MRSA infections are resistant to all beta-lactam antibiotics, including cephalosporins such as cephalexin. Keflex should not be used to treat known MRSA infections. However, Keflex is an excellent choice for the treatment of methicillin-sensitive S. aureus, commonly associated with many uncomplicated skin and soft tissue infections. Keflex can be used as first-line therapy for these types of infections and is the most commonly prescribed antibiotic for that reason.
