None.
Special precautions for use in animals
Due to the likely variability (time, geographical) in the occurrence of cefalexin resistant bacteria, bacteriological sampling and susceptibility testing are recommended.
The veterinary medicinal product should only be used based on susceptibility testing of the bacteria isolated from the animals. If this is not possible, therapy should be based on local epidemiological information.
Use of the veterinary medicinal product should be in accordance with official, national and regional antimicrobial policies.
Use of the veterinary medicinal product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to cefalexin and may decrease the effectiveness of treatment with other beta-lactam antibiotics due to the potential for cross-resistance.
In case of chronic renal insufficiency the dose should be reduced or the dosage interval should be increased.
The tablets are flavoured. In order to avoid any accidental ingestion, store tablets out of reach of the animals.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Penicillins and cephalosporins may cause hypersensitivity (allergy) following injection, inhalation, ingestion or skin contact. Hypersensitivity to penicillin may lead to cross-reactions to cephalosporin and vice versa. Allergic reactions to these substances may occasionally be serious. Do not handle this veterinary medicinal product if you know you are sensitised or if you have been advised not to be in contact with such substances.
Handle this veterinary medicinal product with great care to avoid exposure, taking all recommended precautions. If you develop symptoms following exposure such as skin rash, you should seek medical advice and show the doctor this warning. Swelling of the face, lips or eyes or difficulty breathing are more serious symptoms and require urgent medical attention.
To avoid accidental ingestion of the veterinary medicinal product by a child, divided or unused tablets should be returned to the open blister pocket and placed back in the outer carton.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.
Wash hands after use.
Special precautions for the protection of the environment
Not applicable.
Other precautions

Very rare
(<1 animal / 10,000 animals treated, including isolated reports):
Lethargy
a Mild and transient. The symptoms were reversible in most cats without symptomatic treatment.
b The treatment should be discontinued.
Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for respective contact details.
Use during pregnancy, lactation or lay
Laboratory studies in rats and mice have not produced any evidence of teratogenic effects.
The safety of the veterinary medicinal product in dogs and cats has not been established during pregnancy and lactation. Use only according to the benefit-risk assessment by the responsible veterinarian.
Interaction with other medicinal products and other forms of interaction
In order to ensure efficacy, the veterinary medicinal product should not be used in combination with bacteriostatic antibiotics (macrolides, sulfonamides and
tetracyclines). Concurrent use of first generation cephalosporins with aminoglycoside antibiotics or some diuretics such as furosemide can enhance nephrotoxicity risks.
Amount(s) to be administered and administration route
For oral use.
The recommended dose is 15-30 mg cefalexin per kg body weight twice a day, during at least 5 consecutive days. An extended course of treatment may be prescribed by the responsible veterinarian in cases of, for example, urinary tract infections or bacterial dermatitis.
To ensure a correct dosage body weight should be determined as accurately as possible to avoid underdosing.
The following table is intended as a guide to dispensing the veterinary medicinal product at a dose rate of 15 mg cefalexine per kg body weight twice a day.

Pharmacological particulars
Pharmacotherapeutic group: Antibacterial for systemic use, first-generation cephalosporins
ATCvet Code: QJ01DB01
Pharmacodynamic properties
The mechanism of action of cephalosporins resembles that of the penicillins, in particular that of ampicillin (common beta-lactam ring). Cephalosporins especially has a time-dependent bactericidal effect in dividing bacteria. They bind irreversibly with 'penicillin-binding proteins (PBPs’), enzymes that are needed for the cross-coupling of peptidoglycan strands during the synthesis of the bacterial cell wall. This interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell strength and rigidity, and results in abnormal cell growth and cell lysis. Cephalexin is active against both gram positive and some gram negative bacteria.
The following CLSI cephalothin veterinary breakpoints are available for dogs (CLSI VET01S ed. 5, November 2020).
Cephalothin can be used as indicator of first generation cephalosporins.
Bacterial species
Susceptible
Resistant
Skin and soft tissue infections:
Staphylococcus aureus and
Staphylococcus pseudintermedius
≤ 2 μg/ml
≥ 4 μg/ml
Streptococcus spp. and E. coli
≤ 2 μg/ml
≥ 8 μg/ml
Urinary tract infections:
E. coli, Klebsiella pneumoniae and
Proteus mirabilis
≤ 16 μg/ml
≥ 32 μg/ml
As with penicillins resistance to cefalexin may be due to one of the following mechanisms of resistance: the production of various beta-lactamases, encoded on plasmids or not encoded or by multistage mutations. In the first case, there is almost always cross-resistance with ampicillin; in the other cases there is partial or complete cross-resistance to all penicillins and cephalosporins. Conversely, methicillin-resistant staphylococci are unsusceptible to cephalosporins.
Pharmacokinetic properties
After administration of cephalexin monohydrate cephalexin rapidly and almost completely absorbed in the gastrointestinal tract. Absorption is delayed by food (lower blood levels). Protein plasma binding is approximately 20%.
Single oral administration of 20 mg of cephalexin per kg body weight to dogs resulted in a Tmax of approximately 1-1.5 hours, a Cmax in plasma of about 15 µg/ml and an elimination half-life of about 2 hours (bioavailability = 75%-80%). The volume of distribution is 1.62 l/kg.
Single oral administration of 15 mg cefalexin per kg body weight to cats gave a Tmax of approximately 1.5-2 hours, a Cmax in plasma of about 20 µg/ml and an elimination half-life of approximately 2 hours (bioavailability = 56%). The volume of distribution is 0.83 l/kg.
After absorption, cephalexin is well distributed in the extracellular fluids of the body, however, the passage of biological membranes is limited. The concentrations of cephalexin are highest in the kidneys (urine), and bile, followed by the liver, lungs, heart, skeletal muscle and spleen.
Hardly any metabolism occurs in the liver. Elimination is almost entirely via the kidneys by tubular excretion and glomerular filtration. Cephalexin is also excreted in the bile in a concentration that is equal or somewhat higher than in the blood.
