Cephalexin Tablets: First-Generation Cephalosporin Antibiotic

Cephalexin is a first-generation cephalosporin Antibiotic used extensively in veterinary medicine. While these specific tablets are originally approved for human use, they are a primary treatment choice for veterinarians on an extra-label basis for dogs and cats. Cephalexin works by disrupting the formation of the bacterial cell wall, causing the bacteria to rupture. It is particularly effective against Gram-positive bacteria, most notably Staphylococcus, making it one of the most common medications prescribed for bacterial skin infections.

Prescription Required

Cephalexin is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. Professional diagnosis is necessary to ensure the bacteria causing the infection are susceptible to cephalosporins. While generally very safe, Cephalexin can cause gastrointestinal upset (vomiting or diarrhea) in some pets; administering the medication with food can often help minimize these effects. It is vital to complete the full course of treatment as prescribed by your veterinarian to prevent the return of the infection and the development of antibiotic resistance.
