Clinical information

Citramox 1000 mg/g Powder for Use in Drinking Water for Chickens, Turkeys, Ducks and Pigs — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 27 Mar 2026.

Pigs: For the treatment of pasteurellosis.
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.
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:
x mg veterinary
medicinal product per
kg bodyweight per day
X
mean bodyweight (kg)
of animals to be treated
Mean daily water consumption (litres) per animal
= mg of veterinary
medicinal product /
litre of drinking
water
Medicated water should be the only source of drinking water during the treatment
period.
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
animals. In order to obtain the correct dosage, the concentration of amoxicillin
may need to be adjusted accordingly.
AN: 03669/2024 & 03670/2024
Chickens
The recommended dosage is 15 mg amoxicillin trihydrate per kg bodyweight
(corresponding to 15 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
(corresponding to 20 mg product/kg bodyweight/day) for 3 consecutive days.
Turkeys
Recommended dosage is 15-20 mg amoxicillin trihydrate/kg bodyweight
(corresponding to 15-20 mg product/kg bodyweight/day) for 3 days or in severe
cases for 5 days.
Pigs:
Recommended dosage is 20 mg amoxicillin trihydrate/kg bodyweight
(corresponding to 20 mg product/ kg bodyweight/day) 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.
Solubility in drinking water varies depending on temperature and water quality.
Maximum solubility is approximately 1 g/l at 4 ºC in soft water but increases to 2
g/l at 20 ºC in hard water.
For stock solutions and when using a proportioner, take care not to exceed the
maximum solubility which can be achieved under the given conditions. Adjust
flow rate settings of the dosing pump according to concentration of the stock
solution and water intake of the animals to be treated.
This veterinary medicinal product should not be administered to horses or to
rabbits, guinea pigs, hamsters, gerbils or any other small herbivore.
Do not use in cases of hypersensitivity to penicillins or other ß-lactam antibiotics.

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 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.
