The presence of the disease in the herd must be established before the veterinary
medicinal product is used.
Chickens
Treatment and metaphylaxis of Chronic Respiratory Disease caused by Mycoplasma
gallisepticum and Airsacculitis and Infectious Synovitis caused by Mycoplasma
synoviae susceptible to tiamulin.
The presence of the disease in the flock must be established before the veterinary
medicinal product is used.
Turkeys
Treatment and metaphylaxis of Infectious Sinusitis and Airsacculitis caused by
Mycoplasma gallisepticum, Mycoplasma synoviae and Mycoplasma meleagridis
susceptible to tiamulin.
The presence of the disease in the flock must be established before the veterinary
medicinal product is used.
The veterinary medicinal product should be administered using suitably calibrated
equipment.
Guidance for preparing veterinary medicinal product solutions:
When medicating large volumes of water, prepare a concentrated solution first and
then dilute to the required final concentration.
The veterinary medicinal product is soluble and stable from low concentration up to
maximum concentration of the veterinary medicinal product of 500 ml/L (1:2 dilution)
in water of at least 4° C.
Fresh solutions of tiamulin-medicated drinking water should be made up each day.
Any medicated drinking water remaining from the previous day should be discarded.
To ensure a correct dosage, body weight should be determined as accurately as
possible to avoid underdosing. The intake of medicated water depends on the clinical
condition of the animals. In order to obtain the correct dosage the concentration of
tiamulin has to be adjusted accordingly.
Make sure the animals do not have access to non-medicated water during the period
when the medicated water is given.
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.
In order to avoid interactions between the ionophores and tiamulin, the veterinarian
and farmer should check that the feed label does not state that it contains
salinomycin, monensin or narasin.
For chickens and turkeys, in order to avoid interactions between the incompatible
ionophores monensin, narasin or salinomycin and tiamulin, the feed mill supplying
the birds’ feed should be notified that tiamulin will be used and that these
anticoccidials should not be included in the feed or contaminate the feed.
The feed should be tested for the ionophores prior to use if there is any suspicion
that contamination of the feed might occur.
If an interaction does occur, stop tiamulin medication immediately and replace with
fresh drinking water. Remove contaminated feed as soon as possible and replace
with feed not containing the tiamulin-incompatible ionophores.
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:
Dose (ml veterinary
medicinal product per kg
body weight per day)
X
Mean body weight (kg)
of animals to be treated
Mean daily water consumption (litre) per animal per day
= ___ ml veterinary
medicinal product per
litre of drinking water
Pigs
i) For the treatment of Swine Dysentery caused by Brachyspira hyodysenteriae
The dosage is 8.8 mg tiamulin hydrogen fumarate (equivalent to 0.07 ml solution)/kg
body weight administered daily in the drinking water of pigs for 3 to 5 consecutive
days depending on the severity of the infection and/or the duration of the disease.
ii) For the treatment of Porcine Colonic Spirochaetosis (colitis) caused by Brachyspira
pilosicoli.
The dosage is 8.8 mg tiamulin hydrogen fumarate (equivalent to 0.07 ml solution)/kg
body weight administered daily in the drinking water of pigs for 3 to 5 consecutive
days depending on the severity of the infection and/or the duration of the disease.
iii) For the treatment of Porcine Proliferative Enteropathy (ileitis) caused by
intracellularis.
The dosage is 8.8 mg tiamulin hydrogen fumarate (equivalent to 0.07 ml solution)/kg
body weight administered daily in the drinking water of pigs for 5 consecutive days.
iv) For the treatment and metaphylaxis of Enzootic Pneumonia caused by
Mycoplasma hyopneumoniae, including infections complicated by Pasteurella
multocida susceptible to tiamulin.
The dosage is 20 mg tiamulin hydrogen fumarate (equivalent to 0.16 ml solution)/kg
body weight administered daily for 5 consecutive days.
v) For the treatment of Pleuropneumonia caused by Actinobacillus pleuropneumoniae
susceptible to tiamulin.
The dosage is 20 mg tiamulin hydrogen fumarate (equivalent to 0.16 ml solution)/kg
body weight administered daily for 5 consecutive days.
Chickens
For the treatment and metaphylaxis of Chronic Respiratory Disease caused by
Mycoplasma gallisepticum and Airsacculitis and Infectious Synovitis caused by
Mycoplasma synoviae.
The dosage is 25 mg tiamulin hydrogen fumarate (equivalent to 0.2 ml solution)/kg
body weight administered daily for the period of 3 to 5 consecutive days.
Turkeys
For the treatment and metaphylaxis of Infectious Sinusitis and Airsacculitis caused by
Mycoplasma gallisepticum, Mycoplasma synoviae and Mycoplasma meleagridis.
The dosage is 40 mg tiamulin hydrogen fumarate (equivalent to 0.32 ml solution)/kg
body weight administered daily for the period of 3 to 5 consecutive days.
Do not use in pigs and birds that could receive veterinary medicinal products
containing monensin, narasin or salinomycin during or for at least seven days before
or after treatment with tiamulin. Severe growth depression or death may result.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.
See section 3.8 for information regarding interaction between tiamulin and
ionophores.

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 its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
Pigs with reduced water intake and/or in a debilitated condition should be treated
parenterally.
The water intake of birds should be monitored at frequent intervals during treatment,
especially in hot weather, because water intake may be depressed during the
administration of tiamulin. This appears to be a concentration-dependent effect and
does not appear to have any adverse effect on the overall performance of the birds
or efficacy of the veterinary medicinal product. 500 mg tiamulin hydrogen fumarate in
4 litres of water may reduce intake by approximately 10% and 500 mg tiamulin
hydrogen fumarate in 2 litres of water by 15% in chickens. In turkeys, this effect is
more marked, with approximately a 20% reduction observed and therefore it is
recommended not to exceed a concentration of 500 mg tiamulin hydrogen fumarate
in 2 litres of the drinking water.

Special precautions for safe use in the target species:
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
target bacteria. In some European regions, an increasing proportion of Brachyspira
hyodysenteriae isolates from clinical cases demonstrate significantly reduced in vitro
susceptibility to tiamulin.
Inappropriate use of the veterinary medicinal product may increase the prevalence of
bacteria resistant to tiamulin.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This veterinary medicinal product may cause skin and eye irritation. When mixing,
direct contact with the skin and eyes should be avoided by wearing impermeable
rubber gloves and safety glasses.
In case of accidental eye contact, irrigate the eyes thoroughly with clean running
water immediately. Seek medical advice if irritation persists.
Contaminated clothing should be removed and any splashes on to the skin should be
washed off immediately.
Wash hands after use.
Special precautions for the protection of the environment:
Not applicable.
Tiamulin has been shown to interact with ionophores such as monensin, salinomycin
or narasin and may result in signs indistinguishable from an ionophore toxicosis.
Animals should not receive veterinary medicinal products containing monensin,
salinomycin or narasin during or at least 7 days before or after treatment with
tiamulin. Severe growth depression, ataxia, paralysis or death may result.
If signs of an interaction do occur, stop both the administration of tiamulin-medicated
drinking water and also the administration of ionophore-contaminated feed
immediately. The feed should be removed and replaced with fresh feed not
containing the anticoccidials monensin, salinomycin or narasin.
Concomitant use of tiamulin and the divalent ionophore anticoccidials lasalocid and
semduramicin do not appear to cause any interaction, however the concomitant use
of maduramicin may lead to a mild to moderate growth depression in chickens. The
situation is transient and recovery normally occurs within 3 - 5 days following
withdrawal of tiamulin treatment.
This veterinary medicinal product does not require any special storage conditions.
