Wherever possible, the use of the veterinary medicinal product should be based on
susceptibility testing and take into account official and local antimicrobial policies.

insufficiency the dose should be reduced.
The veterinary medicinal product is not recommended for use in dogs less than 6 kg

Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Cephalosporins may cause sensitisation (allergy) following injection, inhalation,
ingestion or skin contact. Sensitivity to penicillins may lead to cross sensitivity to
cephalosporin and vice versa. Allergic reactions to these substances may
occasionally be serious.
1. People with known hypersensitivity to cephalosporins should avoid contact with the
veterinary
medicinal product.
2. Handle this veterinary medicinal product with great care to avoid exposure, taking
all recommended precautions. 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. Swellings of the face, lips or eyes
or difficulty breathing are more serious symptoms and require urgent medical
attention.
In case of accidental ingestion, particularly by a child, seek medical advice
immediately and show the package leaflet or the label to the physician.
