A List of Clavamox Side Effects in Dogs

Clavamox is a broad spectrum antibiotic obtained by combining clavulanate potassium and amoxicillin. While amoxicillin per se, is quite potent against several pathogens, the addition of clavulanate potassium further increases its potency by making the resulting drug effective against both beta-lactamase and non-beta-lactamase producing organisms. This means that such potentiated drug can be increasingly effective in dogs affected by infections caused by pathogens such as staph, proteus, klebsiella, and pasteurella, explains veterinarian Adam Honeckman in a paper for the Florida Veterinarian Medical Association.


Giving a Dog Clavamox

Clavamox is a prescription drug that requires a veterinary prescription. It is available in tablet form but also as a liquid suspension. Dog owners dealing with canines reluctant to swallow pills may benefit from hiding the pill inside a chunk of hot dog or administering the pill using pill pockets, often sold at veterinarian offices.

Clavamox is commonly prescribed to prevent or treat a variety of infections in dogs. Since most penicillin drugs are excreted through the kidney as urine, such drugs make great candidates for treating urinary tract infections.

Other common uses are to treat skin infections, bone infections, wound infections and infections of the mouth,just to name a few.

Clavamox for Dogs Side Effects


While Clavamox may generally have a wide margin of safety, like other antibiotics, it may cause side effects in dogs. The most common side effect of clavomox for dogs affects the gastrointestinal system. A dog throwing up from Clavamox is often caused by stomach irritation, and it may be prevented by administering some food prior to giving the drug, suggests veterinarian Mark Papich, in an article for Pet Place.

Diarrhea is another common side effect mostly attributed to the fact that antibiotics are known for changing the bacterial flora population in the animal's intestine. This at times can be prevented by asking the vet to prescribe probiotics to help colonize the dog’s intestinal tract with good bacteria.

As with other medications, dogs may also suffer from an allergic reaction to Clavamox. Signs of allergic reactions include shortness of breath, hives, swelling of the lips, tongue or face, rash, and fainting. In this case, a veterinarian should be notified immediately and the reaction should be recorded in the dog's chart for future reference.

In order to be effective in treating a dog's infection, Clavamox should be administered as prescribed. Stopping an antibiotic too early may cause left-over bacteria to spread, and ultimately, cause more problems, including becoming resistant to the antibiotic.
