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

Pigs: treatment of clinical respiratory infections caused by
hyopneumoniae and Pasteurella multocida susceptible to doxycycline.
Chickens and turkeys: treatment of clinical respiratory infections associated with

To be administered in drinking water.
Dosage:
In pigs and chickens
20.0 mg doxycycline per kg of body weight daily (equivalent to 40.0 mg product per kg
of body weight), administered in the drinking water for 5 consecutive days.
In turkeys
25 mg doxycycline per kg of body weight daily (equivalent to 50.0 mg product per kg of
body weight), administered in the drinking water for 5 consecutive days.
Administration:
Based on the recommended dose, and the number and weight of the animals to be
treated, the exact daily amount of the product should be calculated according to the
following formula:
..... mg product per kg body weight
per day
x
Mean body
weight (kg) of
animals to be
treated
Mean daily water consumption (litre per animal)
=.... mg product per litre
of drinking water
To ensure a correct dosage body weight should be determined as accurately as
possible.
To ensure a correct dosage body weight should be determined as accurately as
possible.
The uptake of medicated water is dependent on the clinical conditions of the animals.
In order to obtain the correct dosage, the concentration in drinking water may have to
be adjusted. The use of suitably calibrated weighing equipment is recommended if part
packs are used. The daily amount is to be added to the drinking water such that all
medication will be consumed in 24 hours. Medicated drinking water should be freshly
prepared every 24 hours. It is recommended to prepare a concentrated pre-solution -
approximately 100 grams product per litre drinking water - and to dilute this further to
therapeutic concentrations, if required. The maximum solubility of the product in water
is 72 g/L. Alternatively; the concentrated solution can be used in a proportional water
medicator.
It should be ensured that all animals intended to treat should have free access to the
drinking facilities. At the end of treatment, the watering equipment should be cleaned
adequately to avoid the uptake of remaining quantities in sub-therapeutic doses. The
medicated water should be the only source of drinking water, throughout the treatment
period. The medicated water must not be made or stored in a metal container and use
in oxidized drinking equipment. Solubility of the product is pH dependent and it will
precipitate if it is mixed in an alkaline solution.

Do not use in case of hypersensitivity to the active substance or to any of the
excipients.
Do not use when tetracycline resistance has been detected in the herd/flock due to the
potential for cross resistance.
Do not use in animals with hepatic dysfunction.

As for all tetracyclines, on rare occasions allergic reactions and photosensitivity may
occur. If suspected adverse reactions occur, treatment should be discontinued. If you
notice any serious effects or other effects not mentioned in this leaflet, please inform
your veterinary surgeon.

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

Special precautions for use in animals
Inappropriate use of the product may increase the prevalence of bacteria resistant to
tetracycline due to the potential for cross resistance.
Due to variability (time, geographical) in susceptibility of bacteria for doxycycline,
bacteriological sampling and susceptibility testing of micro-organisms from diseased
animals on farm are highly recommended.
A high resistance rate of , isolated from chickens, against tetracyclines has been
documented. Therefore, the product should be used for the treatment of infections
caused by
As eradication of the target pathogens may not be achieved, medication should
therefore be combined with good management practices, e.g. good hygiene, proper
ventilation, no overstocking.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
Direct contact of the product with the skin, eyes and mucous membranes should be
avoided.
People with known hypersensitivity to tetracyclines should avoid contact with the
veterinary medicinal product.
Wear protective gloves and goggles when reconstituting or administering the solution.
Wash exposed skin after preparation. In case of accidental projection into the eyes,
rinse abundantly with water. Do not smoke, eat or drink when handling the product.
In case of accidental ingestion, seek medical advice immediately and show the
package leaflet or the label to the physician. Inflammation of the face, lips or eyes or
respiratory difficulties are the most serious signs which require urgent medical
attention.

Do not administer concurrently with feed overloaded with polyvalent cations such as
Ca
2+
, Mg
2+
, Zn
2+
and Fe
3+
because the formation of doxycycline complexes with these
cations is possible. Do not administer together with antacids, kaolin and iron
preparations as tetracyclines are bacteriostatic antimicrobials, do not administer in
conjunction with bactericidal antibiotics like beta-lactams. It is advised that the interval
between administration of other products containing polyvalent cations should be 1-2
hours because they limit the absorption of tetracycline.
Doxycycline increases the action of anticoagulants.
