Was your cat prescribed Clavamox? Here's what you should know

We'll walk you through the possible side effects and dosage.

If your cat is diagnosed with an infection, your vet may prescribe Clavamox to help them feel better. Clavamox is an antibiotic used to treat several ailments in cats and dogs. It’s always helpful to study up on a new medication before you start giving it to your pet, so we spoke with a veterinarian to get the rundown on Clavamox for cats, including side effects and proper dosage.

What is Clavamox and why is it prescribed for cats? 

Clavamox is a brand name for the combination antibiotic amoxicillin and clavulanate potassium, which is used to treat several infections in cats and dogs, Dr. Emily Singler, VMD explains. 

“This type of amoxicillin medication has an additional ingredient to help keep bacteria from breaking the amoxicillin down before it can do its job,” Dr. Singler adds. 

Your cat should only be taking Clavamox if your vet recommends it. Sometimes antibiotics are unnecessary for certain infections or diseases. Using the incorrect dose of antibiotics when they don’t treat the condition can contribute to adverse reactions, antibiotic shortages and resistance, Dr. Singler warns. 

“Clavamox is only available by prescription,” Dr. Singler says. The medicine can be dispensed directly by a vet or from a pharmacy with a prescription. You can get Clavamox and other medications for your cat at the guaranteed lowest prices on FetchPetRx.com.

Side effects of Clavamox in cats

There are a few possible side effects of Clavamox for cats, including:

  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Lethargy

Let your vet know if your cat has had an allergic reaction to similar antibiotics, as it may help them to determine if Clavamox is safe for your feline. Veterinarians might prescribe a different medication if your cat already has an upset stomach or isn’t eating well, as Clavamox can be tough on stomachs, Dr. Singler notes.

Clavamox dosage for cats

Clavamox dosages, which come as a liquid or tablet (to be chewed or swallowed), depend on a cat’s weight — your veterinarian can recommend the proper dosage for your pet, Dr. Singler shares. 

The liquid version of Clavamox must be kept refrigerated — it typically expires after 10 days. The antibiotic is usually given every 12 hours or twice daily, Dr. Singler adds. 

Pet parents should remember to give the appropriate dose prescribed to the cat, and it should be taken until they’re finished unless told otherwise by the vet.
