How Long Does Cephalexin Work For Dogs?

Cephalexin, an antibiotic, starts its action against the bacteria responsible for a skin infection rapidly after administration. Despite this rapid onset, it’s important to note that visible improvement in the skin infection may not become apparent until approximately 2 to 3 days after beginning the medication. It’s crucial to strictly adhere to the dosage instructions provided on your cephalexin medication bottle and complete the full course of treatment, even if the skin infection appears to be improving. This ensures that all bacteria causing the infection are completely eradicated, reducing the risk of a recurrence. (Publication date: February 17, 2020)

When determining the appropriate duration of cephalexin treatment for dogs, it’s crucial to consider the recommended dosage based on their weight. Typically, the dosage ranges from 10 to 18 mg per pound (22 to 40 mg/kg) and should be administered orally every 6 to 12 hours. The duration of treatment can span anywhere from 7 to 28 days. It’s important to note that in some cases, the treatment period may extend for up to a week beyond the resolution of symptoms or until a negative culture test confirms the absence of infection. This comprehensive approach helps ensure the effectiveness of cephalexin therapy in addressing various canine health issues.
