Prepare the solution with fresh potable water immediately before use. Any medicated
water which is not consumed within 24 hours should be discarded and the medicated
drinking water replenished.
In order to ensure consumption of the medicated water, animals should not have
access to other water supplies whilst being treated. To ensure a correct dosage,
bodyweight should be determined as accurately as possible. The intake of medicated
water depends on the clinical condition of the animal. In order to obtain the correct
dosage, the concentration of amoxicillin may need to be adjusted accordingly. The
use of suitably calibrated measuring equipment is recommended.
Based on the recommended dose and the number and weight of animals to be
treated, the exact daily concentration of the veterinary medicinal product should be
calculated according to the following formula:

of the active substance.

product/kg bodyweight/day) for 3 consecutive days.
Turkeys:
Recommended dosage is 15-20 mg amoxicillin trihydrate (equivalent to 13.1 - 17.4
mg amoxicillin)/kg bodyweight per day (corresponding to 27-35 mg veterinary
medicinal product/kg bodyweight/day) for 3 days or in severe cases for 5 days.
Pigs:
For the treatment of pasteurellosis: Administer in the drinking water to give 20 mg
amoxicillin trihydrate (equivalent to 17.4 mg amoxicillin)/kg bodyweight

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.

Pigs: The uptake of medication by animals can be altered as a consequence of
illness. In case of insufficient uptake of water, animals should be treated parenterally.

Special precautions for safe use in the target species:
Not effective against beta-lactamase producing organisms. Use of the product should
be in accordance with official, national and regional antimicrobial policies.
Use of the product should be based on identification and susceptibility testing of the
target pathogen(s). If this is not possible, therapy should be based on
epidemiological information and knowledge of susceptibility of the target pathogens
at farm level, or at local/regional level.
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
the treatment.
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 veterinary medicinal product if you know you are sensitised, or if
you have been advised not to work with such preparations.
Handle this veterinary medicinal product with great care to avoid exposure, taking all
recommended precautions.
If you develop symptoms following exposure such as a skin rash, you should seek
medical advice immediately and show the package leaflet or the label to the
physician. Swelling of the face, lips or eyes or difficulty with breathing are more
serious symptoms and require urgent medical attention.

mask respirator conforming to European Standard EN149 or a non-disposable
respirator to European Standard EN140 with a filter to EN143 and gloves should be

water. Wash hands after use.
Special precautions for the protection of the environment:
Not applicable.

Amoxicillin exerts its bactericidal action by inhibition of bacterial cell wall synthesis
during multiplication. It is therefore in principle not compatible with bacteriostatic
antibiotics (e.g. tetracyclines, macrolides and sulphonamides) which inhibit
multiplication.
Synergism occurs with ß-lactam antibiotics and aminoglycosides.
