Ceporex Vet contains cefalexin, a broad spectrum antibiotic widely used for soft tissue infections in dogs and cats. Antibiotic sensitivity testing is used where possible to confirm that Ceporex is active against the bacteria involved in any particular infection. However its broad spectrum of activity and ability to get into a wide variety of body tissues, means that Ceporex is a good choice of antibiotic for a wide range of infections even without laboratory  confirmation. It is normally dosed twice daily in dogs and cats, at a dose rate of 15-30mg/kg bodyweight.

Injection (Cefalexin/Cephalexin) » Multi-dose glass vial containing 100ml

Ceporex 180 mg/ml Suspension for injection for cattle, cats and dogs


Ceporex Injection is a white to cream coloured mobile suspension of sodium cefalexin equivalent to 180 mg/ml cefalexin.


Ceporex Injection is indicated for antibiotic therapy in cattle, cats and dogs. Cefalexin is a broad spectrum cephalosporin antibiotic with bactericidal activity against a wide range of Gram-positive and Gram-negative bacteria.

The following micro-organisms have been shown to be sensitive to cefalexin in vitro:

Staphylococcus spp. (including penicillin-resistant strains)

Streptococcus spp. Actinomyces bovis
Corynebacterium spp. Haemophilus spp.
Pasteurella spp. Erysipelothrix rhusiopathiae
Escherichia coli Clostridium spp.
Proteus spp. Salmonella spp.
Micrococcus spp. Fusobacterium spp.
Moraxella spp. Peptostreptococcus spp.
Actinobacillus lignieresi Peptococcus spp.

When susceptible organisms are present, Ceporex Injection is indicated in the treatment of infections of the respiratory tract, urogenital tract, the skin and localised infections in soft tissues in dogs and cats. In dogs it may also be effective in the treatment of the gastrointestinal tract.

Trials have shown Ceporex Injection to be of particular value in treating metritis, foot infections, wounds and abscesses and in the treatment of septicaemic mastitis to supplement intramammary therapy in cattle.

Dosage and administration

Before withdrawal of a dose the vial should be shaken to re-suspend the contents.

This product does not contain an antimicrobial preservative. Use a dry needle and syringe. Swab the septum before removing each dose.

Dogs and cats

The recommended dose is 10 mg/kg once daily for up to 5 days. Any variation should be at the prescribing veterinary surgeons discretion, e.g. in severe or acute conditions. The following is intended as a guide:

Animal Weight Dose volume
Cats: up to 4.5 kg 0.25 ml
Dogs: small 5–9.0 kg 0.25–0.5 ml
medium 9.0–27.0 kg 0.5–1.5 ml
large 27.0–54.0 kg 1.5–3.0 ml

Ceporex Injection may be administered by either the subcutaneous or intramuscular route. After administration massage the injection site.

The recommended dose for cattle is 7 mg/kg (1 ml/ 25 kg) once daily for up to 5 days.

Ceporex Injection should be administered by the intramuscular route.

Contra-indications, warnings, etc

Hypersensitivity to cefalexin is very rare. However, Ceporex Injection should not be administered to animals which are known to be hypersensitive to cefalexin.

Ceporex Injection is not suitable for intravenous or intrathecal administration.

As with other antibiotics which are excreted mainly by the kidneys, unnecessary accumulation may occur in the body when renal function is impaired. In cases of known renal insufficiency the dose should be reduced.

Operator warnings

Care should be taken to avoid accidental self-injection. In the case of accidental self-injection, seek medical advice immediately. Cephalosporins may cause sensitisation (allergy) following injection, inhalation, ingestion or skin contact. Sensitivity to penicillin may lead to cross sensitivity to cephalosporins and vice versa. Allergic reactions to these substances may occasionally be serious.

Wash hands after use.


Administration of Cefalexin at up to twice the recommended dose in cattle and at up to three times the recommended dose in dogs and cats does not produce any adverse effects.

Withdrawal periods:

Cattle - 19 days.

Cattle (milk) – Zero hours.

Animals for human consumption must not be slaughtered during treatment.

For animal treatment only. Keep out of the sight and reach of children.

Pharmaceutical precautions

Protect from light. Do not store above 30°C. Shake well before use. Do not mix with any other veterinary product. After withdrawal of the first dose, use the product within 28 days.

In the presence of water hydrolysis of cefalexin occurs. It is important, therefore, that a dry syringe is used when extracting suspension for injection to avoid contaminating the remaining contents of the vial with drops of water.


Dispose of any unused product and empty containers in accordance with guidance from your local waste regulation authority.

Further information

Cefalexin is rapidly absorbed after injection. Peak blood concentrations are generally achieved within one hour of administration. Cefalexin is excreted in the urine in high concentration.

Cefalexin is resistant to the action of staphylococcal penicillinase and is therefore active against the strains of Staphylococcus aureus that are insensitive to penicillin (or related antibiotics such as ampicillin or amoxycillin) because of production of penicillinase. Cefalexin is also active against the majority of ampicillin-resistant E. coli.

My female gave birth and her glands are swolen up she doesnot want the babies to drink

VioVet Visitor

The puppies are 3 weeks old her boobs are swollen there is milk

  • Non-Executive Director

Usually it is best to leave her alone with the puppies and she will allow them to start to suckle. Unless there are clear signs of infection, there is no reason to give her antibiotic. Ideally your vet should check her over to ensure there is no medical problem present.
