Special precautions for use in animals
Not effective against beta-lactamase producing organisms.
Pigs: The uptake of medication by animals may be altered as a consequence of illness. In case of insufficient water uptake, animals should be treated parenterally instead.
Official, national and regional antimicrobial policies should be taken into account when the product is used.
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 (regional, farm level) epidemiological information about susceptibility of the target bacteria.
Use of the product deviating from the instructions given in the SPC may increase the prevalence of bacteria resistant to the 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.
People with known hypersensitivity the active substance or if you have been advised not to work with such preparations should avoid contact with the veterinary medicinal product.
Handle this 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 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.
Avoid inhalation of dust. Wear either a disposable half-mask respirator conforming to European Standard EN149 or a non-disposable respirator to European Standard EN140 with a filter to ENl43.
Wear gloves during preparation and administration of medicated water or liquid feed.
Wash any exposed skin after handling the product or medicated water or feed. Wash hands after use.
Adverse reactions (frequency and seriousness)
Penicillins and cephalosporins may cause hypersensitivity reactions which may occasionally be serious.
Use during pregnancy, lactation or lay
Laboratory studies in rats have not produced any evidence of a teratogenic effect due to the administration of amoxicillin.
Use only according to the benefit/risk assessment of the responsible veterinarian.
Do not use in birds producing eggs for human consumption or within 3 weeks of onset of laying.
Interaction with other medicinal products and other forms of interaction
The product should not be administered with antibiotics that have a bacteriostatic mode of action, such as tetracyclines, macrolides, sulphonamides.
Amounts to be administered and administration route
In drinking water use.
Prepare the solution with fresh potable water immediately before use. Any medicated water which is not consumed within 12 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.
The following formula may be used to calculate the required concentration of product (in milligrams of product per litre of drinking water):
x mg product per kg bodyweight per day |
X |
mean bodyweight (kg) of animals to be treated |
= x mg product per litre drinking water |
|
mean daily water consumption (l) per animal |
To ensure a correct dosage, bodyweight should be determined as accurately as possible to avoid underdosing. The uptake of medicated water depends on the clinical condition of the animal. In order to obtain the correct dosage the concentration of amoxicillin has to be adjusted taking into account water intake.
Chickens
The recommended dosage is 15 mg amoxicillin trihydrate per kg bodyweight per day (corresponding to 30 mg product/kg·bodyweight/day).
The total period of treatment should be for 3 days or in severe cases for 5 days.
Ducks
Recommended dosage is 20 mg amoxicillin trihydrate/kg bodyweight per day (corresponding to 40 mg product/kg bodyweight/day) for 3 consecutive days.
Turkeys
Recommended dosage is 15-20 mg amoxicillin trihydrate/kg bodyweight per day (corresponding to 30-40 mg product/kg·bodyweight/day) for 3 days or in severe cases for 5 days.
Pigs
Administer in the drinking water to give 20 mg amoxicillin trihydrate/kg bodyweight (corresponding to 40 mg product/kg·bodyweight) daily for up to 5 days.
After the end of the medication period the water supply system should be cleaned appropriately to avoid intake of sub-therapeutic amounts of the active substance.
Overdose (symptoms, emergency procedures, antidotes), if necessary
No problems with overdosage have been reported. Treatment should be symptomatic and no specific antidote is available.
Withdrawal periods
Meat and offal:
Chickens 1 day
Ducks 9 days
Turkeys 5 days
Pigs 2 days
Not authorised for use in laying birds producing eggs for human consumption and within 3 weeks of onset of laying.
PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group:Beta-lactam antibiotic, penicillins
ATCVet code:QJ01CA04
Pharmacodynamic properties
Amoxicillin is a bactericidal antibiotic belonging to the group of semisynthetic penicillinswith a broad spectrum of activity against Gram positive and Gram negative bacteria. It owes its activity to the inhibition of the development of the peptidoglycan network structure in the bacterial cell wall.
Pharmacokinetic particulars
Amoxicillin is well absorbed following oral administration and it is stable in the presence of gastric acids. Excretion of amoxicillin is mainly in the unchanged form via the kidneys to give high concentration in renal tissue and urine. Amoxicillin is well distributed in body fluids.
Studies in birds have indicated that amoxicillin is distributed and eliminated more rapidly than in mammals.
Biotransformation appeared a more important route of elimination in birds than in mammals.
