Special precautions for use in animals
In animals with hepatic and renal dysfunction, the dosing regimen should be carefully
evaluated and the use of the product based on a risk/benefit evaluation by the
veterinary surgeon.
Caution is advised in the use in small herbivores other than those which have been
contraindicated in the section 4.3.
Due to the likely variability (time, geographical) in the occurrence of resistance of
bacteria for amoxicillin, bacteriological sampling and susceptibility testing are
recommended. Increased antimicrobial resistance are reported among E. Coli
isolates including multidrug-resistant E. Coli. Special precautions should be taken
when multi-drug resistance are suspected based on susceptibility testing. Whenever
possible, the product should only be used based on susceptibility testing.
Use of the product deviating from the instructions given in the SPC may increase the
prevalence of bacteria resistant to amoxicillin and may decrease the effectiveness of
treatment with other beta lactam antimicrobials or other classes of antimicrobials due
to the potential for cross resistance.
Official, national and regional antimicrobial policies should be taken into account
when product is used.
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 penicillins may lead
to cross reactions to cephalosporins and vice versa. Allergic reactions to these
substances may occasionally be serious.
Do not handle this product if you know you are sensitised, or if you have been
advised not to
work with such preparations.
Handle this 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.
Wash hands after handling the tablets.

Chloramphenicol, macrolides, sulfonamides and tetracyclines may inhibit the
antibacterial effect of penicillins because of the rapid onset of bacteriostatic action.
The potential for allergic cross-reactivity with other penicillins should be considered.
Penicillins may increase the effect of aminoglycosides.

Do not store above 30C.
Any unused tablet portion should be returned to the open blister and used within 4
days.
