Clinical information

Amoxy Active 697 mg/g Oral Powder for Pigs and Chickens — SPC Details

Chickens: Treatment of respiratory tract infections and gastro-intestinal tract
infections caused by
micro-organisms susceptible to amoxicillin.
In drinking water use in chickens.
Pigs:
The recommended dose is 11.2 mg amoxicillin per kg of body weight daily (corresponding
to 16.1 mg of the veterinary medicinal product per 1 kg of body weight per day) given for 3
- 5 consecutive days.
Chickens:
The recommended dose is 20 mg amoxicillin per kg of body weight daily (corresponding to
28.7 mg of the veterinary medicinal product per 1 kg of body weight per day) given for 3 - 5
consecutive days.
To ensure a correct dosage, body weight should be determined as accurately as possible
to avoid underdosing. The use of suitably calibrated measuring equipment is
recommended.
In drinking water use:
For the preparation of medicated water, the body weight of the animals to be treated and
their actual daily water consumption should be taken into account. Consumption may vary
depending on factors like species, age, state of health, breed and husbandry system (e.g.
different temperature, different light regimes). The intake of medicated water depends on
the clinical condition of the animals. In order to obtain the correct dosage the concentration
of amoxicillin may need to be adjusted accordingly. Preparation of medicated water should
provide an amount to be consumed within the next 12 hours.
AN: 01619/2023Page 4 of 6
Any unused medicated water should be discarded after 12 hours, and freshly medicated
water for the next 12 hours should be prepared.
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:
…mg veterinary medicinal product/ x average body weight (kg)
kg body weight/day of animals to be treated
= … mg veterinary
medicinal
average daily water intake (l/animal) product per litre of
drinking water

The veterinary medicinal product should be added to the drinking water by thorough
stirring until the veterinary medicinal product is completely dissolved. Maximum solubility
of the veterinary medicinal product in water is approximately 6 g/litre. Sufficient access to
the system of water supply should be available for the animals to be treated to ensure
adequate water consumption. No other source of drinking water should be available during
the medication period. In free range husbandry systems animals should be kept in the
stable during treatment.
Where applicable the water supply system should be cleaned appropriately after the end
of the medication period to avoid intake of sub-therapeutic amounts of the active
substance.
In-feed use:
The veterinary medicinal product may also be offered via the feed at the recommended
daily dose. This way of administration is only intended for the treatment of individual pigs
on farms where only a small number of pigs are to receive the treatment. Only the pack
size of 100 g is suitable for the in-feed use.
Larger groups should be treated with medicated drinking water.
Before each administration the powder should be thoroughly mixed into a small amount of
food and should be given directly to the animal before the main ration. Care should be
taken that the intended dose will be completely ingested.
Do not use in cases of hypersensitivity to penicillin or other substances of the beta-lactam
group or to any of the excipients.
Do not use in the presence of ß-lactamase-producing bacteria.
Do not use in lagomorphs and rodents such as guinea pigs, hamsters or gerbils.
Do not use in animals with serious kidney malfunction including anuria and oliguria.
Do not use in ruminants or horses.

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 the national competent authority via the
national reporting system. See section ‘Contact details’ of the package leaflet.
Sick animals have an altered drinking behaviour and should be medicated parenterally
where applicable.

Special precautions for safe use in the target species:
Official, national and regional antimicrobial policies should be taken into account when the
veterinary medicinal product is used.
Use of the veterinary medicinal 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 veterinary medicinal 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 may cause hypersensitivity (allergy) following injection, inhalation, ingestion or
skin contact. Hypersensitivity to penicillins may cause cross reactions to cephalosporins
and vice versa. Allergic reactions to these substances may occasionally be serious.
People with known hypersensitivity to beta-lactam antibiotics should avoid contact with the
veterinary medicinal product.
Handle this veterinary medicinal product with great care to avoid exposure, taking all
recommended precautions.
Personal protective equipment consisting of gloves and either a disposable half mask
respirator conforming to European Standard EN149 or a non-disposable respirator
conforming to European Standard EN140 with a filter to EN 143 should be worn when
mixing and handling the veterinary medicinal product. Wash hands after use.
In case of contact with eyes or skin, wash immediately with water.
If you develop symptoms following exposure, such as a skin rash, you should seek
medical advice 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.
Special precautions for the protection of the environment:
Not applicable.
Do not combine with bacteriostatic antibiotics.
Not to be used simultaneously with neomycin since it blocks the absorption of oral
penicillins.
Synergism occurs with ß-lactam antibiotics and aminoglycosides.
Store below 25 ºC.
Store in the original container.
Pigs: meat and offal: 2 days.
Chickens: meat and offal: 1 day.
Not for use in birds producing eggs for human consumption.
AN: 01619/2023Page 5 of 6
