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

For the treatment of enzootic pneumonia caused by tiamulin-susceptible
Mycoplasma hyopneumoniae and mycoplasmal arthritis caused by tiamulin-
susceptible Mycoplasma hyosynoviae.
AN: 04319/2024 & 04402/2024

To ensure a correct dosage body weight should be determined as accurately as
possible.
AN: 04319/2024 & 04402/2024
For the treatment of clinical swine dysentery:
8.1 mg tiamulin base per kg bodyweight (equivalent to 1 ml per 20 kg bodyweight) to
be administered in a single treatment followed by tiamulin in the water or feed.
For the treatment of enzootic pneumonia or mycoplasmal arthritis:
12.1 mg tiamulin base per kg bodyweight (equivalent to 1.5 ml/20 kg bodyweight)
daily for 3 consecutive days.
Depending on the severity of disease it may be necessary to continue treatment by
orally administered tiamulin until 2 days after signs of disease have subsided.
The closures should not be broached more than 5 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 the active substance or to any of the
excipients
Do not use in cases of known resistance to tiamulin.

Pigs:
Rare
(1 to 10 animals / 10,000 animals
treated):
Hypersensitivity reaction
(dermatitis
,
erythema
, pruritus
)
Usually mild and transient but in very rare cases may be serious. Symptomatic
treatment such as electrolyte therapy and an anti-inflammatory therapy may be
useful.
Acute.
Cutaneous.
Intense.
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 the national competent authority via the
national reporting system. See the package leaflet for respective contact details

Inflammation/scarring may occur at the site of injection. For this reason, it is
recommended that the product should be administered into the muscle of the neck.

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
bacteriological sampling and susceptibility testing taking 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 cross-resistance. Long term or repeated use should be
avoided by improving management practice and thorough cleansing and disinfection.
In the absence of a satisfactory response to treatment, the diagnosis should be
reconsidered
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
People with known hypersensitivity to tiamulin should administer the veterinary
medicinal product with caution.
Care should be taken to avoid self-injection. Direct contact with the skin, eyes and
mucous membranes should be avoided when handling the product.
In case of accidental eye contact, irrigate the eyes thoroughly with clean running
water immediately. Seek medical advice immediately and show the package leaflet
or the label to the physician if irritation persists.
In case of accidental spillage onto skin, wash immediately with running water in order
to minimise absorption through the skin.
Wash hands after use.
This product contains sesame oil. Accidental self-injection may result in severe
localised reactions, particularly if injected into a joint or finger. In case of accidental
self-injection, seek medical advice immediately and show the package leaflet or the
label to the physician.
AN: 04319/2024 & 04402/2024
Special precautions for the protection of the environment:
Not applicable.

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

Store below 25 °C. Do not refrigerate or freeze.
Protect from light.

Meat and offal: 21 days
