CLINICAL PARTICULARS


4.1

Target species



Cattle and Sheep.


4.2

Indications for use, specifying the target species



Cattle

For the treatment and control of liver fluke infections in cattle caused by all stages of triclabendazole-susceptible Fasciola hepatica from 2 week old immature to adult fluke.


Sheep

For the treatment and control of liver fluke infections in sheep caused by all stages of triclabendazole susceptible Fasciola hepatica from 2 day old immature to adult fluke.


4.3

Contraindications



None known.


4.4

Special warnings for each target species



Shake the container thoroughly before use.

Assess bodyweight as accurately as possible before calculating dose.

Intensive use or misuse of anthelmintics can give rise to resistance. To reduce this risk, dosing programmes should be discussed with your veterinary adviser.

Efficacy of this product against liver fluke is reduced if triclabendazole-resistant strains are present.


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.

  • Underdosing, which may be due to underestimation of bodyweight, 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 liver fluke (Fasciola hepatica) in cattle and sheep in a number of countries, including ones in the EU. Therefore, the use of this product should be based on local epidemiological information about susceptibility of F. hepatica and recommendations on how to limit further selection for resistance to anthelmintics. To reduce the risk of parasite resistance, dosing programmes should be discussed with a veterinary surgeon. Fasinex 100 contains the anthelmintic triclabendazole and losses associated with resistant strains of fluke in sheep treated with triclabendazole can be significant. If signs of fasciolosis continue after treatment with Fasinex 100, DO NOT REPEAT THE DOSE and do not dose with other products containing triclabendazole. Seek veterinary advice. If resistance is suspected or confirmed, you should change active ingredient on veterinary advice.

4.9

Amount(s) to be administered and administration route



Routine herd/flock treatment (high risk fluke areas)

As a guide, dose all animals exposed to fluke infested pastures preventatively at regular intervals of 10 weeks from March / April through to October / November. In situations where animals are outwintered, a dose in January may also be required. All animals grazing the pasture should be treated at these times. Any bought-in animals should be dosed before joining the main herd/flock. Veterinary advice should be sought with regards to specific preventative dosing regimes.


Routine herd/flock treatment (moderate risk fluke areas)

Dose all animals exposed to fluke-infested pastures at regular intervals of 10 weeks throughout the fluke season, usually from September to January / February. An additional preventative treatment in the spring will assist in reducing the amount of new infection on pasture in the following autumn. Animals bought in from fluke risk areas should be treated before joining the main herd/flock.


Clean drenching equipment before and after use.

Use unaltered product from the original container.

Shake the container thoroughly before use.

Most types of automatic drenching gun may be used.


To ensure a correct dosage, body weight should be determined as accurately as possible. If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or over-dosing.


Accuracy of the dosing device should be checked.

Overdose (symptoms, emergency procedures, antidotes), if necessary



A single oral dose of 150-200 mg triclabendazole/kg of body weight (over 12 times the recommended dose for cattle and 15-20 times the recommended dose for sheep) may lead to side effects such as unsteady gait, dullness and reduced appetite. These side effects are slight and transient. An antidote is not known.

Sheep (meat and offal) – 35 days

Not authorised in cattle and ewes producing milk for human consumption including during the dry period.

Do not use during the last trimester of pregnancy in heifers which are intended to produce milk for human consumption.

PHARMACOLOGICAL PROPERTIES



Pharmacotherapeutic group: Anthelmintic, benzimidazoles and related substances.




ATC Vet Code: QP52 AC01



5.1

Pharmacodynamic properties



Triclabendazole and its metabolites bind to tubulin but at another receptor than other benzimidazoles. Triclabendazole and its metabolites interfere with intracellular transport mechanisms and inhibit protein synthesis.


5.2

Pharmacokinetic properties



Majority of oral dose in rats, sheep, goats and rabbits is eliminated in faeces after 6-10 days as unchanged drug or products of biliary excretion. Urinary excretion is minimal. Sulphone, sulphoxide, ketone and 4-hydroxy triclabendazole derivatives are the main metabolites identified in plasma. Metabolites are excreted via the bile, primarily as conjugates. More than 90% of the total dose of Fasinex 100 is excreted in the faeces, about 5% in the urine and less than 1% in milk. Elimination is virtually complete by 10 days after administration.
