It can be used in all age groups of sheep and lambs, including during pregnancy, and in rams during the breeding season.

Key Features

  • Kills immature & adult liver fluke (Fasciola hepatica) including those resistant to triclabendazole
  • Effective against benzimidazole resistant strains of Haemonchus contortus (Barber Pole Worm)
  • Can be used in any age sheep or lamb including during pregnancy

Flukiver Product Information

Target activity of Flukiver

Flukiver 5% Oral Suspension controls chronic and subacute liver fluke infections caused by adult and immature Fasciola hepatica in sheep and lambs. It can be used on farms with triclabendazole resistance1, and also prevents contamination of pastures with fluke eggs for up to 13 weeks2.

Flukiver also controls Oestrus ovis (Sheep Nasal Bot Fly) and controls inhibited, immature and adult stages of Haemonchus contortus (Barber Pole Worm) including benzimidazole resistant strains. 

Ticks (Ixodes ricinus) feeding on sheep at the time of treatment are likely to produce fewer viable eggs.

Special warnings

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 investigation using appropriate tests (eg 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 closantel has been reported in Haemonchus species outside the EU. Therefore the use of this product should be used upon local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

Special precautions for use in animals
