ToggleWhat Is Clavacillin?
Clavacillin is a broad-spectrum antibiotic used in veterinary medicine to treat a wide range of bacterial infections. It’s a combination drug made of amoxicillin trihydrate and clavulanate potassium, which work together to combat bacteria more effectively.
Amoxicillin is a penicillin-type antibiotic, while clavulanate helps prevent bacterial resistance. This makes medication highly efficient against bacteria that produce beta-lactamase enzymes, which usually inactivate many antibiotics. Its formulation is specially designed for use in dogs and cats and is available in chewable tablets, making it easier to administer.
Key Uses of Cloxacillin
Cloxacillin is used to treat several types of infections in pets, including:
- Skin infections (such as wounds, abscesses, and cellulitis)
- Respiratory tract infections
- Urinary tract infections
- Periodontal (dental) infections
- Soft tissue infections
The drug works by destroying the cell walls of bacteria, thereby stopping their growth. Its dual-action formula makes it a first-choice treatment for mixed or resistant bacterial infections.

How Does Cloxacillin Work?
Clavacilli combines the power of two active ingredients:
- Amoxicillin: Destroys the bacteria’s cell walls, leading to their death.
- Clavulanate potassium: Prevents bacteria from producing enzymes that could resist the effects of amoxicillin.
This synergistic action increases the efficacy of the treatment and reduces the chance of bacterial resistance, which is a growing concern in both human and animal healthcare.
Dosage and Administration Guidelines
Clavacillin must be given strictly under the guidance of a licensed veterinarian. The appropriate dose is determined by your pet’s weight, the seriousness of the infection, and the specific bacteria causing it.
General Dosage (For Dogs and Cats):
- Standard Dose: 6.25 mg per pound of body weight
- Frequency: Every 12 hours
- Duration: 5 to 7 days (or as directed)
Chewable tablets come in various strengths (e.g., 62.5 mg, 125 mg, 250 mg), so it’s important to follow your vet’s dosage instructions carefully.
Important Tips:
- Administer with food to reduce stomach upset
- Make sure to finish the entire prescribed course, even if your pet seems to get better before it’s completed
- Do not skip or double doses
