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. Prevents pasture contamination for up to 13 weeks. 

Withdrawal Period 
Meat - 42 days.
Not to be administrated to lactating sheep producing milk for human consumption.
