Suggested dosing schedule

Fluke

All sheep on fluke-infested pasture should be dosed at regular intervals during the fluke season (Sept–Mar). Regional fluke forecasts from DEFRA assist in the choice of dosing time and interval.

Since closantel has been shown to delay egg-laying for up to 13 weeks after artificial infection, treatment intervals of 10–12 weeks throughout the fluke season are recommended. In severe fluke seasons, more frequent dosing may be necessary.

The treatment of ewes with a single dose of Flukiver in the spring will contribute to reducing pasture contamination during the following summer and autumn.

Any sheep brought in from liver fluke infested areas should be dosed before they join the flock.

H. contortus

For the treatment and prevention of benzimidazole resistant and susceptible H. contortus, dose at lambing to help prevent pasture contamination by infected ewes. Treat all animals at 6 weekly intervals during high risk periods in summer and autumn.
