The intake of medicated feed depends on the clinical condition of the animals. In
order to obtain the correct dosage, the concentration of tiamulin may need to be
adjusted using the following formula:
Dose rate (mg/kg) x mean bodyweight (kg)
Kg premix/tonne feed = __________________________________
Mean feed intake (kg) x premix strength (g/kg)
To ensure a correct dosage, body weight should be determined as accurately as
possible.
Pigs
Treatment and metaphylaxis of Swine Disentery caused B. hyodysenteriae,
treatment of Porcine Colonic Spirochaetosis (colitis) caused by B. pilosicoli.
Dosage: 5 – 10 mg tiamulin hydrogen fumarate (equivalent to 4.05 – 8.1 mg tiamulin
base) / kg bodyweight daily administered for 7 to 10 consecutive days. The dosage
will normally be achieved by an inclusion level of 100 – 200 ppm tiamulin hydrogen
fumarate in the finished feed providing that feed intake is unaffected.
Treatment of Porcine Proliferative Enteropathy (ileitis) caused by L. intracellularis
Dosage: 7.5 mg tiamulin hydrogen fumarate (equivalent to 6.075 mg tiamulin base) /
kg bodyweight daily administered for 10-14 consecutive days. The dosage will
normally be achieved by an inclusion level of 150 ppm tiamulin hydrogen fumarate in
the finished feed providing that feed intake is unaffected.
AN: 02212/2024 and 02213/2024Page 5 of 9
Treatment of Enzootic Pneumonia caused by
Dosage: 5.0 – 10.0 mg tiamulin hydrogen fumarate (equivalent to 4.05 – 8.1 mg
tiamulin base) / kg bodyweight daily administered for 7 to 10 consecutive days. The
dosage will normally be achieved by an inclusion level of 100 - 200 ppm tiamulin
hydrogen fumarate in the finished feed, providing that feed intake is unaffected.
Secondary infection by organisms such as Pasteurella multocida and
pleuropneumoniae may complicate enzootic pneumonia and require specific
medication.
Chickens (broilers, layer hens, for reproduction and pullets)
Treatment and metaphylaxis of chronic respiratory disease (CRD) caused by M.
gallisepticum and airsacculitis and .
Dosage - Treatment and metaphylaxis: 25 mg tiamulin hydrogen fumarate
(equivalent to 20.25 mg tiamulin base) / kg body weight daily administered for the
period of 3 to 5 consecutive days. This is normally achieved by an inclusion level of
250 - 500 ppm tiamulin hydrogen fumarate in the finished feed provided that feed
intake is unaffected.
Turkeys (for reproduction and poults)
Treatment and metaphylaxis of infectious sinusitis and airsacculitis caused by M.
gallisepticum, M. synoviae and M. meleagridis.
Dosage - Treatment and metaphylaxis: 40 mg tiamulin hydrogen fumarate
(equivalent to 32.4 mg tiamulin base) / kg body weight daily administered for the
period of 3 to 5 consecutive days. This is normally achieved by an inclusion level of
250 - 500 ppm tiamulin hydrogen fumarate in finished feed provided that feed intake
is unaffected.
Metaphylaxis with tiamulin should only be initiated after confirmed infection with M.
gallisepticum, M. synoviae and M. meleagridis and then as an aid in the metaphylaxis
strategy to reduce the clinical signs and mortality from respiratory disease in flocks,
where infection in ovum is likely because the disease is known to exist in the parent
generation. The metaphylaxis strategy should include efforts to eliminate the infection
from the parent generation.
Rabbits
Treatment of Epizootic Rabbit Enterocolitis (ERE) and metaphylaxis of ERE in farms
with clinical signs of ERE in the previous fattening cycle as part of a programme
including measures aiming to eradicate or control the infection in the farm.
Dosage: 3 mg tiamulin hydrogen fumarate (equivalent to 2.43 mg tiamulin base) / kg
body weight daily. The dosage will normally be achieved by an inclusion level of 40
ppm tiamulin hydrogen fumarate in the finished feed provided that feed intake is
unaffected. Treatment should be administered until 2 - 3 days after clinical signs
have resolved. Metaphylaxis should be administered during 3 – 4 weeks from the first
week after weaning.
Medicated feed may be pelleted using a pre-conditioning step for 5 minutes at a
temperature not exceeding 75°C.

The uptake of medication by animals can be altered as a consequence of illness. For
animals with a reduced feed intake, treat parenterally using an appropriate injectable
veterinary medicinal product.
Long term or repeated use should be avoided by improving management practice
and thorough cleansing and disinfection.
In case of reduced feed intake, the inclusion levels in feed may need to be increased
to achieve target dosage.
Special precautions for safe use in the target species:
Do not use the veterinary medicinal product in liquid feed.
Due to the likely variability (time, geographical) in the occurrence of resistance of
bacteria for tiamulin, the use of the veterinary medicinal product should be based on
susceptibility testing and take into account official and local antimicrobial policies.
Use of the veterinary medicinal product deviating from the instructions given in the
SPC may increase the prevalence of bacteria resistant to tiamulin and may decrease
the effectiveness of treatment with other pleuromutilins due to the potential for
crossresistance.
If there is no response to treatment within 3 days, the diagnosis should be re-
established.
Inform the feed supplier that tiamulin will be used, to avoid incorporating of ionophore
products containing monensin, narasin and salinomycin products in the feed and to
AN: 02212/2024 and 02213/2024Page 3 of 9
avoid contamination of the feed. In case of a suspected contamination, test the feed
for the presence of these ionophores before feeding. If adverse effects occur due to
an interaction, stop administration of the feed immediately. Remove the
contaminated feed as soon as possible and replace with uncontaminated feed.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Direct contact with the skin, eyes and mucous membranes and inhalation of dust
should be avoided. Personal protective equipment consisting of overalls,
impermeable rubber gloves, safety glasses and a disposable half-mask respirator
conforming to European Standard EN 149 or a non-disposable respirator to
European Standard EN 140 with a filter to EN 143 should be worn when handling the
veterinary medicinal product.
In case of accidental eye contact, irrigate the eyes thoroughly with clean running
water immediately. Seek medical advice if irritation persists and show the package
leaflet or the label to the physician.
Contaminated clothing should be removed and any splashes on to the skin should be
washed off immediately.
Wash hands after use.
Accidental ingestion should be avoided. In case of accidental ingestion, seek medical
advice immediately and show the package leaflet or the label to the physician.
People with known hypersensitivity to tiamulin should avoid contact with the
veterinary medicinal product.

Tiamulin is known to produce clinically important (often lethal) interactions with
ionophore antibiotics, including monensin, narasin, salinomycin. Therefore, animals
should not receive products containing such compounds during or for at least seven
days before or after treatment with this veterinary medicinal product. Severe growth
depression, ataxia, paralysis or death may result Tiamulin may lessen the
antibacterial activity of beta-lactam antibiotics, whose action is dependent on
bacterial growth.
