​Cephalexin For Dogs: How it Helps

Cephalexin is one of several antibiotics (medicines that kill bacteria) used to treat a range of bacterial infections in people, dogs, and other animals. Like other antibiotics, it does not work against viral infections.

It belongs to the class of antibiotics known as a first-generation cephalosporin. The drug also goes by the name cefalexin. These are the generic names for a drug that is known by the brand names Keflex, Biocef, and Keftab. It is an oral medication and can be given with or without food. Offering the drug with food, however, can reduce the risk of some of the more common side effects.

Tell your vet if your dog is taking any other kind of drug, including herbal and over-the-counter remedies, or has a medical issue that might rule out cephalexin treatment, including:

• side effects from other drugs
• digestive upset
• kidney disease
• allergies
• pregnancy, nursing

The World Health Organization includes this drug on its List of Essential Medicines. It is effective against gram-positive and gram-negative bacteria, and it kills these bugs by disrupting the growth of the bacterial cell wall and causing it to rupture.
