Moxapulvis 500 mg/g Powder for Use in Drinking Water — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

Treatment of infections in chickens, turkeys and ducks caused by bacteria
susceptible to amoxicillin.
Pigs: For the treatment of pasteurellosis caused by Pasteurella multocida
to amoxicillin.

For use in drinking water.
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.
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 dayX
mean bodyweight (kg)
of animals to be
treated
mean daily water consumption (l) per animal
= x mg product per
litre drinking water
The maximum solubility of the product is 65 g/L.
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.
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.
Chickens:
The recommended dosage is 15 mg amoxicillin trihydrate (equivalent to 13.1 mg
amoxicillin) per kg bodyweight per day (corresponding to 27 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 (equivalent to 17.4 mg
amoxicillin)/kg bodyweight per day (corresponding to 35 mg 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 product/kg
bodyweight/day) for 3 days or in severe cases for 5 days.

Unlimited renewal: April 2023
AN: 03899/2022Page 4 of 6Pigs:
Administer in the drinking water to give 20 mg amoxicillin trihydrate (equivalent to
17.4 mg amoxicillin)/kg bodyweight (corresponding to 35 mg product/kg bodyweight)
daily.
The dose should be divided and administered at approximately 12 hourly intervals for
up to 5 days.
The calculated dose should be measured out with calibrated scales.

Do not use in rabbits, hamsters, gerbils and guinea pigs, or to birds producing eggs
intended for human consumption.
Not effective against beta-lactamase producing organisms.
Do not use in known cases of hypersensitivity to penicillin or other substances of the
beta-lactam group or to any of the excipients.

Penicillins and cephalosporins may cause hypersensitivity following administration.
Allergic reactions to these substances may occasionally be serious.

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 use in animals
Not effective against beta-lactamase producing organisms. 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.
1) Do not handle this product if you know you are sensitised or if you have been
advised not to work with such preparations.
2) Handle this product with great care to avoid exposure, taking all recommended
precautions.
3) 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.

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.
