Clavacillin is used to treat skin infections (including wounds and abscesses), respiratory infections, urinary tract infections, periodontal disease, and other susceptible bacterial infections in dogs and cats. It is effective against many gram-positive and gram-negative bacteria when the organism is sensitive to this combination therapy.
Amoxicillin works by inhibiting bacterial cell wall synthesis, causing bacteria to die. Clavulanic acid is a beta-lactamase inhibitor that blocks an enzyme (beta-lactamase) some bacteria produce to resist antibiotics. Together, they allow the medication to be effective against bacteria that would otherwise be resistant to amoxicillin alone.
Clavacillin is for veterinary use only. Animals with known penicillin allergies should not receive this medication. Common side effects may include gastrointestinal upset such as diarrhea or vomiting. Always complete the full course of treatment as prescribed by your veterinarian, even if symptoms improve earlier. Consult your veterinarian for proper diagnosis and dosing for your pet.
