CATS: Skin and soft tissue infections such as wounds, abscesses, and cellulitis/dermatitis due to susceptible strains of the following organisms: β-lactamase-producing Staphylococcus aureus, non-β-lactamase-producing Staphylococcus aureus, Staphylococcus spp., Streptococcus spp., E. coli, and Pasteurella spp. Urinary tract infections (cystitis) due to susceptible strains of E. coli.

Therapy may be initiated with Clavamox before obtaining results from bacteriological and susceptibility studies.

CONTRAINDICATIONS: The use of this drug is contraindicated in animals with a history of an allergic reaction to any of the penicillins or cephalosporins.

WARNINGS: Safety of use in pregnant or breeding animals has not been determined. Store in a dry, cool place at temperatures not above 25°C (77°F). Do not remove from foil strip until ready to use.

ADVERSE REACTIONS: Clavamox contains a semisynthetic penicillin (amoxicillin) and has the potential for producing allergic reactions. If an allergic reaction occurs, administer epinephrine and steroids.

What should I discuss with my veterinarian before giving Clavamox to my pet? Tell your veterinarian if your pet has ever had an allergic reaction to another penicillin or a cephalosporin. Tell your veterinarian if your pet has liver or kidney disease. Tell your veterinarian if your pet is pregnant or lactating or if your pet could become pregnant during treatment.

How should Clavamox be given? Give this medication exactly as directed by your veterinarian. Clavamox should be given with food. Keep water available for your pet. The usual dose of Clavamox in dogs is 6.25 mg/lb of dog's body weight twice a day, and in cats, it is 62.5 mg (1 ml) twice a day. Clavamox can be used to treat many different types of bacterial infections such as respiratory, ear, urinary tract, and skin. Clavamox may also be used for purposes other than those listed. Give all of the Clavamox that is prescribed for your pet. Symptoms may improve before the infection is completely treated.

What are the potential side effects of Clavamox? Contact your veterinarian immediately if your pet experiences diarrhea that is severe and lasts longer than 3 days. Stop giving Clavamox and seek emergency veterinary medical care in the event of an allergic reaction (shortness of breath, hives, swelling of the lips, tongue, or face, rash, or fainting). Other less serious side effects such as mild diarrhea, nausea, vomiting, or yeast or fungal infection may be more likely to occur. Continue to give Clavamox and notify your veterinarian if these symptoms occur. Talk to your veterinarian about any side effect that seems unusual or bothersome to your pet.

What happens if I miss giving a dose of Clavamox? Give the missed dose as soon as you remember unless it is almost time for the next regularly scheduled dose. Do not give a double dose unless otherwise directed by your veterinarian.

What happens if I overdose my pet on Clavamox? Seek emergency veterinary medical treatment if an overdose is suspected. Symptoms of Clavamox overdose may include nausea, vomiting, rash, drowsiness, hyperactivity, or kidney problems.

What should I avoid while giving Clavamox to my pet? There are no restrictions on food or activity during treatment with Clavamox unless otherwise directed by your veterinarian.

What other drugs will affect Clavamox? Before giving Clavamox, tell your veterinarian if your pet is being given another antibiotic (for the same or a different infection), allopurinol or probenecid. You may not be able to give Clavamox, or you may need to have the dosage adjusted. Drugs other than those listed here may also interact with Clavamox. Talk to your veterinarian or pharmacist before giving any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.
