Cephalexin is a common antibiotic used to treat bacterial infections in dogs. This calculator helps determine the correct dosage of Cephalexin 500mg capsules for your dog based on their weight and the type of infection being treated.
Introduction
Cephalexin is a first-generation cephalosporin antibiotic that is effective against many common bacterial infections in dogs. It's available in tablet and capsule forms, with 250mg and 500mg strengths commonly used in veterinary practice.
The dosage of Cephalexin for dogs depends on several factors including the dog's weight, the type of infection, and whether it's a new or recurring infection. This calculator provides a quick reference for determining the appropriate dosage.
Dosage Calculation
The standard dosage for Cephalexin 500mg capsules is calculated based on the dog's weight. The general guideline is:
- 10-20mg per pound of body weight, given twice daily
- Maximum daily dose is 200mg per pound of body weight
- Dosage may be adjusted based on the severity of infection and response to treatment
For example, a 20-pound dog would typically receive 200-400mg of Cephalexin per day, divided into two doses of 100-200mg each.
Administration
Cephalexin 500mg capsules should be given with food to prevent stomach upset. The capsules should be swallowed whole with a small amount of water.
For dogs that have difficulty swallowing capsules, the tablets may be crushed and mixed with food or water. However, this should only be done under veterinary supervision.
Always follow your veterinarian's specific instructions regarding dosage, frequency, and duration of treatment.
