Supaverm Product Information

Target activity of Supaverm

Supaverm targets infections in sheep and lambs of liver fluke (sub-acute and chronic fascioliasis caused by immature and adult Fasciola hepatica), gastrointestinal roundworms, lungworms, tapeworms and nasal bot flies. 

It also controls inhibited, immature and adult stages of Haemonchus contortus (Barber Pole Worm) including benzimidazole resistant strains. 

Supaverm is effective against benzimidazole resistant strains of:

  • Gastrointestinal roundworms: Ostertagia spp, Trichostrongylus spp, Nematodirus spp, Cooperia spp, Oesophagostomum spp, Chabertia ovina, Bunostomum spp, Trichurus ovis, Strongyloides papillosus
  • Lungworm: Dictyocaulus filaria
  • Tapeworm: Moniezia spp

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

Special precautions for use in animals

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 benzimidazoles (which includes mebendazole) has been reported in Teladorsagia, Haemonchus, Cooperia and Trichostrongylus species in small ruminants in a number of countries including the EU. 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


Special precautions to be taken by the person administering Supaverm to sheep
