Clavamox is the brand name of a prescription antibiotic for dogs and cats manufactured by veterinary pharmaceutical company Zoetis. It contains the penicillin-class antibiotic amoxicillin plus clavulanate potassium. This second ingredient, also called clavulanic acid, is combined with penicillin-class antibiotics to help overcome drug-resistant bacteria.


As an antibiotic, Clavamox is prescribed to treat and prevent certain bacterial infections. It is effective against many types of bacteria. Clavamox doesn't work against viral, fungal or parasitic infections. This drug is often used for superficial infections, such as abscesses, cellulitis, pyoderma and infected wounds. It's also commonly used for periodontal, upper respiratory tract and bladder and other urinary tract infections.


Clavamox is administered orally in tablet or liquid suspension form. The typical canine dosage is 6.25mg per pound of body weight twice daily for one week; always use exactly as prescribed by your veterinarian. Symptoms sometimes clear before the infection is fully eliminated, so never stop use early just because your dog seems better. Store the container tightly sealed at room temperature, out of reach of children and pets. Clavamox isn't for use in pets allergic to any penicillin-class antibiotic.
