What is Keflex (Cephalexin) and How Does it Work?

Keflex, known generically as cephalexin, is an antibiotic that treats a variety of bacterial infections. It falls under the class of cephalosporins, which work by disrupting the formation of the bacterial cell wall, ultimately leading to the death of the bacteria. Keflex is commonly prescribed for skin infections, respiratory infections, ear infections, and infections of the bone.

When you take Keflex, the active ingredient travels through your bloodstream to the site of infection. It binds to specific proteins in the bacteria and interferes with the synthesis of peptidoglycan, a critical component of the bacterial cell wall. This action makes the wall vulnerable, resulting in cell lysis and the elimination of the bacteria.

Key benefits of Keflex include:

• Treating various bacterial infections effectively.
• Absorbed well when taken orally, which enhances patient compliance.
• Generally well-tolerated with a favorable safety profile.

Though Keflex is effective, it’s important to use it only for infections that are confirmed to be bacterial. Misuse can lead to antibiotic resistance. Always follow your healthcare provider’s instructions regarding dosage and duration of the treatment.

If you miss a dose, take it as soon as you remember. If it’s close to the time for your next dose, skip the missed dose and resume your regular schedule. Never double the dose.
