The best treatment for bacterial infections depends on the infection type, severity, and bacteria involved. Antibiotics like cephalexin, a cephalosporin antibiotic, are commonly prescribed for infections such as skin infections, urinary tract infections, and respiratory infections caused by susceptible bacteria. Cephalexin works by disrupting bacterial cell wall synthesis, effectively killing the bacteria. Dosage typically ranges from 250-500 mg every 6-12 hours, depending on the condition. Always consult a healthcare provider for proper diagnosis and prescription, as misuse can lead to resistance. Completing the full course is crucial to prevent recurrence.
