How Does Cephalexin For Dogs Work

How and When to use Cephalexin (Keflex, keforal, Daxbia) – Doctor Explains

Like all antibiotics, cephalexin works by killing bacteria that cause infections.

More specifically, the Merck Veterinary Manual notes that cephalexin is quite active against many gram-positive bacteria.

However, cephalexin is just moderately active against gram-negative bacteria. For anaerobic bacteria penicillin is more effective than cephalexin.

Anaerobic bacteria are those organisms growing without oxygen.

If your vet suspects a bacterial infection, she vet will take skin scrapings and/or a blood test.

This will help to determine what kind of bacteria is responsible for your dogs problem.

Based on the findings, she may prescribe cephalexin or penicillin to eliminate the bacteria.

The choice of drug and dosage is also based on your dogs medical history.

What Are The Main Differences Between Cephalexin And Amoxicillin

Buy Cephalexin Online (Non Prescription Antibiotic) Capsules

Cephalexin is a prescription medication used to treat a variety of bacterial infections. It is a first-generation cephalosporin antibiotic, which belongs under the larger classification of beta-lactam antibiotics. Cephalexin interferes with cell wall synthesis by binding penicillin-binding proteins inside the cellular wall. Ultimately, when cephalexin is dosed appropriately, it causes lysis, or destruction, or the bacterial cell. Different bacterial types contain different bacterial binding proteins, so cephalexins effectiveness varies with different types of bacteria.

Cephalexin is available as an oral tablet or capsule, as well as an oral suspension. The brand name of cephalexin is Keflex. It is used by infants, children, and adults.

Amoxicillin is a prescription medication also used to treat a variety of bacterial infections. It is a penicillin antibiotic but also falls under the larger classification of beta-lactam antibiotics. Amoxicillin, like cephalexin, interferes with cell wall synthesis by binding penicillin-binding proteins inside the cellular wall leading to the destruction of the bacterial cell.

Amoxicillin is available as an oral tablet or capsule, chewable tablet, as well as an oral suspension. The brand name of amoxicillin is Amoxil or Polymox. It is used by infants, children, and adults.
