What Is Cephalexin?
Cephalexin (brand name Keflex) is an oral, first-generation cephalosporin antibiotic commonly prescribed for mild-to-moderate bacterial infections. It is one of the most frequently used antibiotics in the US, valued for its broad activity against common gram-positive bacteria, oral availability, and excellent safety profile — including in pregnancy (category B).
What Does Cephalexin Treat?
- Skin and soft tissue infections (SSTIs) — including cellulitis, impetigo, and wound infections
- Strep throat (pharyngitis / tonsillitis)
- Respiratory tract infections — mild community-acquired pneumonia, bronchitis
- Urinary tract infections (UTIs) — uncomplicated bladder infections
- Bone infections (osteomyelitis) — step-down therapy after IV antibiotics
- Otitis media (ear infections)
How Does Cephalexin Work?
Like all beta-lactam antibiotics, cephalexin works by binding to penicillin-binding proteins (PBPs) in bacterial cell walls, inhibiting the cross-linking of peptidoglycan chains. This weakens the bacterial cell wall, causing the bacteria to lyse (burst) and die. It is bactericidal — it kills bacteria rather than just inhibiting their growth.
Dosage Overview
- Adults: 250–500 mg every 6 hours, or 500 mg every 12 hours for 7–14 days
- Skin infections: 500 mg every 6 hours is often recommended
- Children: 25–50 mg/kg/day in divided doses
