established before the veterinary medicinal product is used. The veterinary
medicinal product should only be used if pigs are expected to develop the
disease within 2–3 days.

A single intramuscular injection of 2.5 mg tulathromycin/kg bodyweight
(equivalent to 1 ml/10 kg bodyweight) in the neck.
For treatment of pigs over 40 kg bodyweight, divide the dose so that no more
than 4 ml are injected at one site.
For any respiratory disease, it is recommended to treat animals in the early
stages of the disease and to evaluate the response to treatment within 48 hours
after injection. If clinical signs of respiratory disease persist or increase, or if
relapse occurs, treatment should be changed, using another antibiotic, and
continued until clinical signs have resolved.
To ensure a correct dosage, bodyweight should be determined as accurately as
possible. The closure may be safely punctured 15 times. In order to prevent
excessive broaching of the stopper, a suitable multiple dosing device should be
used.

Do not use in cases of hypersensitivity to macrolide antibiotics or to any of the
excipients.

Undetermined frequency

available data)

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.

None.

Special precautions for safe use in the target species:
Cross resistance occurs with other macrolides. Do not administer
simultaneously with antimicrobials with a similar mode of action such as other
macrolides or lincosamides.
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.
Official, national and regional antimicrobial policies should be taken into account
when the veterinary medicinal product is used.
Use of the veterinary medicinal product deviating from the instructions given in
the SPC may increase the prevalence of bacteria resistant to tulathromycin and
may decrease the effectiveness of treatment with other macrolides,
lincosamides and group B streptogramins due to the potential for cross
resistance.
If a hypersensitivity reaction occurs appropriate treatment should be
administered without delay.
Special precautions to be taken by the person administering the veterinary
medicinal product to animals:
Tulathromycin is irritating to eyes. In case of accidental eye exposure, flush the
eyes immediately with clean water.
Tulathromycin may cause sensitisation by skin contact resulting in e.g.
reddening of the skin (erythema) and/or dermatitis. In case of accidental spillage
onto skin, wash the skin immediately with soap and water.
Wash hands after use.
In case of accidental self-injection, seek medical advice immediately and show
the package leaflet or the label to the physician.
If there is suspicion of a hypersensitivity reaction following accidental exposure
(recognised by e.g. itching, difficulty in breathing, hives, swelling on the face,
nausea, vomitus) appropriate treatment should be administered. Seek medical
advice immediately and show the package leaflet or the label to the physician.
Special precautions for the protection of the environment:
Not applicable.
