Special precautions for use in animals
As with other antibiotics which are excreted mainly by the kidneys, unnecessary
accumulation may occur in the body when renal function is impaired. In case of
known renal insufficiency, the dose should be reduced and antimicrobials known to
be nephrotoxic should not be administered concurrently.
This product should not be used to treat puppies of less than 1 kg of bodyweight.
Use of the product deviating from the instructions given in the SPC may increase the
prevalence of bacteria resistant to the cefalexin and may decrease the effectiveness
of treatment with other cephalosporins and penicillins, due to the potential for cross-
resistance.
Use of the product should be based on susceptibility testing of the bacteria isolated
from the animal. If this is not possible, therapy should be based on local
epidemiological information.
Official, national and regional antimicrobial policies should be taken into account
when the product is used.
As the tablets are palatable for animals there is a danger of excessive ingestion. The
tablets must therefore be stored out of the reach of 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 sensitivity to cephalosporin and . 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. Take care to avoid prolonged skin contact. Wash hands after use.
3- 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 with breathing are more-serious symptoms and require urgent medical
attention.

and some diuretics such as furosemide can enhance nephrotoxicity risks.
The bactericidal activity of cephalosporins is reduced by concomitant administration
of bacteriostatic acting compounds (tetracyclines, chloramphenicol, macrolides and
rifampicin).
