two week old early immature to adult fluke, and so is indicated against both acute
and chronic fascioliasis.
Given as an oral drench. Suitable for use through most types of automatic
drenching gun. Shake container thoroughly before use and use undiluted product
from the original container.
Unscrew the blue cap from the container and replace it with the white spigot cap
provided. If using an automatic drenching-gun, attach the tube from the
application device to the white spigot cap. After use, remove the white spigot cap
and close the container with the blue cap.

It can be safely administered to young or pregnant cattle.
Recommended dose rate: 7.5mg levamisole hydrochloride/kg and 12mg
triclabendazole/kg. This is equivalent to 1ml of the product per 10kg bodyweight.
To ensure administration of correct dose, body weight should be determined as
accurately as possible; accuracy of the dosing device should be checked.
None
When the product is used at the recommended dose rate side effects are rare. At
higher dosages, transient side effects due to levamisole may occur (i.e. salivation
and slight muscle tremors).
Efficacy of this product against roundworms is reduced if levamisole resistant
strains are present. 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:
•
an extended period of time
•
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 levamisole has been reported in Teladorsagia species in cattle in
developed countries such as New Zealand. Therefore the use of this product should
be based on local (regional, farm) epidemiological information about susceptibility of
the nematodes and recommendations on how to limit further selection for resistance
to anthelmintics.

i. Special precautions for use in animals
Assess bodyweight as accurately as possible before calculating the dosage.
Clean drenching equipment before and after use.
Intensive use or misuse of anthelmintics can give rise to resistance. To reduce
this risk, dosing programmes should be discussed with your Veterinary
Adviser.

ii. Special precautions to be taken by the person administering the product
When administering, do not eat, drink or smoke.
Wash splashes from eyes and skin immediately.
Immediately remove any contaminated clothing.
Wash hands and exposed skin before meals and after work.
Levamisole can cause idiosyncratic reactions and serious blood disorders in a
very small number of people. If symptoms such as dizziness, nausea,
vomiting or abdominal discomfort are experienced when using the product, or
sore mouth/throat or fever occurs shortly afterwards, then medical advice
should be sought immediately
Do not store above 25
