Dosing Programme:
Routine treatment (Areas of heavy fluke infection)
As a guide, dose all sheep exposed to fluke infected pastures preventatively at regular intervals of 10 weeks from March/April through to October/November. In situations where stock are out-wintered another dose in January may be required. All animals grazing the pasture should be treated at these times. All bought in animals should be dosed before joining the main flock. Veterinary advice should be sought with regard to specific preventative dosing regimes.
Routine treatment (Areas of moderate fluke infection)
Dose all sheep on fluke infected pastures at intervals of 10 weeks throughout the fluke season, usually September to January/ February. All bought in animals should be dosed before joining the main flock.
An additional preventative treatment in the Spring will assist in reducing the amount of new infestation on pasture in the following autumn.
Treatment of sub-acute and acute outbreaks
The flock should be treated immediately after diagnosis and veterinary advice should be sought for subsequent dosing intervals. If a preventative fluke dosing programme is employed, the occurrence of acute fluke is greatly reduced. Retreatment may not be carried out within 8 weeks.
Contra-indications, warnings, etc
Do not use in cases of known hypersensitivity to the active ingredient.
Special warnings
Care should be taken to avoid the following practices, because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
• Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
• Under dosing, which may be due to under estimation of body weight, misadministration of the product or lack of calibration of the dosing device (if any).
Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.
Resistance to triclabendazole has been reported in Fasciola hepatica in sheep. Therefore, the use of this product should be based on local (regional / farm) epidemiological information about susceptibility of the Fasciola hepatica and recommendations on how to limit further selection for resistance to anthelmintics.
Special precautions for use in animals
Only use for liverfluke strains susceptible to triclabendazole. Care must be taken not to damage the mouth or pharyngeal region when dosing. Clean drenching equipment before and after use. Shake container before use. Use unaltered product from the original container.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
When using the product do not eat, drink or smoke. Wear gloves. Wash splashes from eyes and skin immediately. Take off any contaminated clothing immediately. Wash hands and exposed skin before meals and after work. In cases of hypersensitivity and contact allergy, direct skin contact and inhalation should be avoided.
Other precautions
The use of Tribex 5% may have harmful effects on fish and aquatic invertebrates. Sheep must not have any access to surface water such as streams, ponds or ditches within 7 days after treatment with Tribex. When spreading manure from treated animals on arable lands a safety distance of 10 m to adjacent surface waters must be kept.
