The Side Effects of Synulox

By Jane Meggitt

Synulox is one of the most common antibiotics prescribed for dogs and cats. If you haven't heard of it, that's because it's marketed under the name Clavamox in the United States. Manufactured by Zoetis, the drug is a combination of the antibiotic amoxicillin and clavulanic acid, which helps amoxicillin fight bacteria normally resistant to penicillin-type medications. Technically, Clavamox contains amoxicillin trihydrate and clavulanate potassium. These drugs can penetrate into most bodily tissues and fluids, excepting spinal fluid and the brain.

Clavamox Uses

If your dog is diagnosed with a periodontal or skin infection -- including abscesses, pyoderma or cellulitis -- your vet may prescribe Clavamox. If your cat suffers from similar skin conditions or a urinary tract infection, he might receive the drug. In both species, it is given for treatment of infected wounds or to ward off potential infection. The drug is not appropriate for small animals, such as rabbits and guinea pigs.

Bacteria Killer

Clavamox eradicates various common bacteria, including:

  • E. coli
  • Pasturella spp.
  • Staphylococcus aureus
  • Staphylococcus spp.
  • Streptococcus spp.

Side Effects and Contraindications

Most animals tolerate Clavamox well, but there are potential side effects. These include:

  • vomiting and nausea
  • diarrhea
  • and loss of appetite.

Pregnant or nursing animals should not receive Clavamox nor should any pet allergic to penicillin. Allergic reactions include breathing difficulties and breaking out in hives. If your pet develops an allergic reaction, call your vet immediately.

If you or anyone in your family is allergic to penicillin, avoid exposure to this drug. If necessary, wear disposable gloves while administering the pills or liquid medication and wash your hands thoroughly afterward.
