Cephalexin is a broad-spectrum antibiotic from the cephalosporin class used to treat bacterial infections in dogs. It works by disrupting bacterial cell wall formation and is commonly prescribed for UTIs, skin infections, and wound infections.
The typical dosage is 15-30 mg per kg of body weight given twice daily. For most infections, 15 mg/kg twice daily is effective, while severe infections may require higher doses up to 30 mg/kg twice daily.
While the active ingredient is the same, you should never give human cephalexin to dogs without veterinary approval. Human formulations may contain harmful additives, and proper veterinary dosing is essential for safety and effectiveness.
Common side effects include nausea, vomiting, diarrhea, and loss of appetite. Serious allergic reactions are rare but can occur. Contact your veterinarian if your dog experiences severe vomiting, difficulty breathing, or facial swelling.
Treatment duration typically ranges from 7-14 days depending on the infection type and severity. UTIs often require 7-10 days, while skin infections may need 10-14 days. Always complete the full course as prescribed.
Yes, cephalexin can be given with or without food. Giving it with food may help reduce stomach upset. However, food doesn't significantly affect absorption, so timing with meals is mainly for comfort.
Give the missed dose as soon as you remember, unless it's almost time for the next dose. Never double dose. If you're unsure about timing, contact your veterinarian for guidance.
Cephalexin may interact with certain medications including some diuretics and blood thinners. Always inform your veterinarian about all medications and supplements your dog is taking before starting cephalexin treatment.
