What Clavamox Is Used For
Clavamox is a broad-spectrum antibiotic used to treat certain bacterial infections in pets. It is commonly prescribed for skin and soft tissue infections, periodontal or dental infections, and may also be used for some urinary tract and other susceptible bacterial infections when your veterinarian determines it is appropriate.
It combines amoxicillin, which kills susceptible bacteria, with clavulanate, which helps protect the antibiotic from bacterial enzymes that can otherwise inactivate it. Clavamox does not treat viral infections, and it should only be used when prescribed by a veterinarian.
Side Effects to Watch For
Most pets tolerate Clavamox reasonably well, but side effects can happen.
- Common side effects can include stomach upset, vomiting, diarrhea, and decreased appetite.
- Some pets may drool or resist the medication, especially if they dislike the taste or feel nauseated.
- Allergic reactions are possible with penicillin-type antibiotics and may include facial swelling, hives, itching, trouble breathing, or collapse.
- Contact your vet promptly if your pet has severe vomiting or diarrhea, marked lethargy, worsening illness, or refuses food repeatedly while taking this medication.
- Tell your veterinarian if your pet has had a previous reaction to penicillin or related antibiotics.
Dosing & Administration
Always follow your vet's instructions exactly. Do not change the amount, schedule, or length of treatment unless your veterinarian tells you to.
Clavamox is usually given by mouth as a tablet or liquid. It is commonly given with food to help reduce stomach upset. If you are using the liquid form, shake it well and measure carefully using the dosing tool provided by your clinic or pharmacy.
Finish the full prescribed course unless your veterinarian instructs otherwise, even if your pet seems better sooner. If you miss a dose, give it when you remember unless it is almost time for the next one. Do not give two doses at once. If your pet vomits after a dose, or if you are unsure whether the medication was kept down, call your vet for guidance.
