Directions For Use

1. Prepare fresh medicated drinking water daily.

2. Water medicated with Denagard 12.5% should be the only source of drinking water during the treatment period.

3. During treatment, swine should be housed under conditions of adequate space and sanitation.

4. If no response to treatment is obtained within 5 days, re-establish the diagnosis. Failure of response may be related to the presence of nonsusceptible organisms or other complicating disease conditions.

Contra-indications: Swine being medicated with Denagard 12.5% should not have access to or be treated with tiamulin incompatible polyether ionophores (e.g., monensin, lasalocid, narasin, salinomycin and semduramicin).

Cautions: For use in the drinking water of swine only. This drug should not be administered to sows during 4 weeks after service.


Treated swine must not be slaughtered for use in food for at least 3 days after the latest treatment with this drug. Avoid contact with the skin. Direct contact with the skin or mucous membranes during mixing may cause irritation. If contact occurs, wash with soap and water. KEEP OUT OF REACH OF CHILDREN.

Adverse Reactions

i. Overdoses of tiamulin have sometimes produced transitory salivation, vomiting and an apparent calming effect on the pig. In very rare cases, death has been reported.

ii. In rare cases, redness of the skin, primarily over the ham and underline, has been observed during medication.

iii. If signs of toxicity or redness of the skin occurs, promptly discontinue use of medicated water and provide fresh, clean water for drinking.

To report suspected adverse drug events, contact Elanco Canada Limited, 1-800-265-5475.

Clinical Pharmacology

Tiamulin is active against Brachyspira (formerly Serpulina or Treponema) hyodysenteriae. Denagard 12.5% is well absorbed from the gastrointestinal tract of swine and appears in the blood within 30 minutes. Peak concentrations occur at 2-4 hours after the oral administration of a single dose. An average of 85% of a single dose is absorbed, 98% of which is excreted in the urine and feces within 72 hours.

Safety and Efficacy: Extensive field and laboratory testing with tiamulin has shown that this preparation, as recommended, has a high degree of safety. Doses greater than five times the recommended dose produced transitory salivation, emesis, and an apparent calming effect on the pig.


Protect from direct sunlight. Store at room temperature 15 °C-30 °C (59 °F-86 °F).

Presentation: Denagard 12.5% is supplied in a 1 litre (1000 mL) bottle containing 101.21 g of tiamulin (equivalent to 125 g tiamulin hydrogen fumarate) dissolved in an inert carrier.
