Clavaseptin is known as a potentiated antibiotic. It contains two ingredients which work together to significantly increase the effectiveness against certain bacteria. The main antibiotic ingredient (amoxycillin) can be inactivated by certain types of bacteria, rendering them resistant. However the second ingredient (clavulanate) prevents the bacteria from inactivating the antibiotic, allowing the antibiotic to kill the bacteria. Hence Clavaseptin is active against a wide range of bacteria and this combination has become one of the main antibiotics used in veterinary medicine. Tablets are normally given twice daily at a dose rate of 12.5mg/kg bodyweight.

Dosage and administration

The recommended dose of Clavaseptin Palatable Tablets is 10 mg amoxicillin/2.5mg clavulanic acid/kg twice daily by the oral route in dogs and cats according to the following table.

Bodyweight (kg)

50mg tablets 1 tablet per 4kg bodyweight every 12h

250mg tablets 1 tablet per 20kg body weight every 12h

500mg tablets 1 tablet per 40kg bodyweight every 12h



















Duration of treatment:

- 7 days for the treatment of periodontal infections in dogs

- 7 to 14 days for the treatment of skin infections in cats (including wounds and abscesses). The clinical status of animals should be re-evaluated after 7 days and the treatment prolonged for a further 7 days if necessary.

To ensure the correct dosage, bodyweight should be determined as accurately as possible to avoid under-dosing.

Administration is made easier by the palatable nature of the tablet.

Contra-indications, warnings, etc

Do not use in case of hypersensitivity to penicillins or other substances of the β-lactam group.

Do not administer to gerbils, guinea pigs, hamsters, rabbits and chinchillas.

Special precautions for use in animals

In animals with impaired liver and kidney function, the use of the product should be subject to a risk/benefit evaluation by the veterinary surgeon and the posology evaluated carefully.

Caution is advised in the use of Clavaseptin in any other small pet (non food-producing) herbivores.

Use of the product should be based on susceptibility testing.

Inappropriate use of the product may increase the prevalence of bacteria resistant to amoxicillin/clavulanic acid. Use of the product should take into account official and local antimicrobial policies.

Adverse reactions (frequency and seriousness)

Vomiting and diarrhoea may be observed. Treatment may be continued depending on the severity of the undesirable effect observed and a benefit/risk evaluation by the veterinary surgeon.

Hypersensitivity reactions (allergic skin reactions, anaphylaxis) may be observed. In these cases, administration should be discontinued and a symptomatic treatment given.

Use during pregnancy and lactation

The safety of the product has not been established during pregnancy and lactation. Laboratory studies in rats have not produced any evidence of teratogenic, foetotoxic or maternotoxic effects. Use the product only accordingly to the benefit/risk assessment by the responsible veterinarian.

Interaction with other medicinal products and other forms of interaction

The bactericidal activity of amoxicillin may be reduced by the simultaneous use of bacteriostatic substances such as macrolides, tetracyclines, sulfonamides and chloramphenicol.

Overdose (symptoms, emergency procedures, antidotes), if necessary

At three times the recommended dose for a period of 28 days, diarrhoea was observed in dogs. In the event of an overdose, symptomatic treatment is advised.

Operator warning

Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillins may lead to cross reactions to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

1. Do not handle this product if you know you are sensitised, or if you have been advised not to work with such preparations.

2. Handle this product with great care to avoid exposure, taking all recommended precautions.

Further information

Amoxicillin is an aminobenzylpenicillin from the β-lactam penicillin family which prevents the bacterial cell wall formation by interfering with the final step of peptidoglycan synthesis.

Clavulanic acid is an irreversible inhibitor of intracellular and extracellular β-lactamases which protects amoxicillin from inactivation by many β-lactamases.

Amoxicillin/clavulanate has a wide range of activity which includes β‑lactamase producing strains of both Gram-positive and Gram-negative aerobes, facultative anaerobes and obligate anaerobes.

Resistance to β-lactam antibiotics is mainly mediated by β-lactamases which hydrolyze antibiotics such as amoxicillin. It is mostly shown in Pseudomonadaceae (81.25%) and in Enterobacter spp. (55.5%).

After oral administration at the recommended dose in dogs and cats, the absorption of amoxicillin and clavulanic acid is fast. In dogs, the maximum plasma concentration of amoxicillin of 8.5 µg/ml is reached in 1.4 h and the maximum plasma concentration of clavulanic acid of 0.9 µg/ml is reached in 0.9h.

In cats, the maximum plasma concentration of amoxicillin of 6.6 µg/ml is reached in 1.8 h and the maximum plasma concentration of clavulanic acid of 3.7 µg/ml is reached in 0.75h. Elimination is also fast.

After repeated oral administration of the recommended dose in dogs and cats, there is no accumulation of amoxicillin or clavulanic acid and the steady state is reached rapidly after first administration.

Questions & Answers for Clavaseptin Palatable Tablets

Below are some recent questions we've received regarding Clavaseptin Palatable Tablets, including answers from our team.

Ask Your Own Question

Treating an urinary infection

18th Aug 2015

Looking at the difference between clavaseptin vs. clavamox in treating a urinary infection in a dog with elevated liver enzymes.

  • Non-Executive Director

This is like asking the difference between the Boots version of paracetamol and Tesco's. They are both manufactured to the same standards, they contain the same active ingredients and essentially there is no difference. Both antibiotics are equally acceptable to use when there has been an element of liver damage, which is what causes elevated liver enzyme levels in the blood. Likewise they are both indicated for urinary tract infections. More than that it is impossible to say. The choice of antibiotic is down to your vet, who is familiar with your dog.

Drug interaction between clavaseptin and prednisolone

14th Apr 2015

My cat is finishing up her last few doses of clavaseptin. She was given prednisolone a couple weeks prior from another issue..can I start giving her the prednisolone or do I need to wait a while after she finished her clavaseptin?

  • Non-Executive Director

These two medications are often given at the same time, so I would expect to treat the two conditions as appropriate for each. There is no general requirement to not give the two together. Howevere, prednisolone can reduce the immune response (especially at higher doses) so it might be best to ensure that any infection is clear before starting prednisolone again. This is something you should check with your own vet who is familiar with the precise details of this case and will be able to provide more relevant advice.
