What is the recommended dosage for Cephalexin for an adult?

The recommended dosage for Cephalexin in adults is flexible, depending on the severity and type of infection being treated. The correct option indicates that the dosage can be either 250mg every 6 hours or 500mg every 8-12 hours. This range allows healthcare providers to tailor the medication to the patient's specific needs, considering factors like the infection's severity, the patient's kidney function, and any other underlying health issues.

Cephalexin is a first-generation cephalosporin antibiotic commonly used to treat various bacterial infections, and dosing must be adjusted appropriately for effective treatment while minimizing potential side effects. Providing two dosing options gives clinicians the ability to individualize therapy based on clinical judgment and the patient's circumstances.

Other options either suggest dosing regimens that are not standard or fall outside effective ranges for most typical adult bacterial infections, which is why they are not suitable. The flexibility in dosing in the correct answer reflects current clinical practice guidelines that emphasize personalized patient care.
