DOSING PROGRAMME:
Routine treatment (Areas of heavy fluke infection)
As a guide, dose all cattle 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.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
No adverse effects were reported following a dose of 12.5 times the recommended
dose. At higher doses (up to 20-fold), mild transient ataxia and weight loss were
observed in some animals 3-6 days after treatment.
