Risk of resistance? LOW
There are a few reports on resistance of Oesophagostomum worms to benzimidazoles, levamisole and pyrantel (mainly in Europe) but so far the problem is much less frequent and severe than in sheep or cattle.
This means that if this product does not achieve the expected efficacy against the mentioned parasites, there is a certain risk that it is due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.
- Benzimidazoles, e.g. albendazole, febantel, fenbendazole, oxfendazole, etc.
- Macrocyclic lactones (e.g. abamectin, doramectin, eprinomectin, ivermectin, moxidectin, etc.).
- Tetrahydropyrimidines (e.g. morantel, pyrantel): effective only against certain gastrointestinal roundworms. Not available in some countries. Resistance to morantel has been reported in some countries.
- Piperazine. Effective only against certain gastrointestinal roundworms (mainly ascarids).
These alternative products may not be available in all countries or may not be effective against all the concerned parasites.
It is highly recommended to periodically check the resistance status of each property performing appropriate tests (e.g. fecal egg counts) under supervision of a veterinary doctor. Such tests are now routinely available for most producers in developed countries.

This product is a classic anthelmintic for pig & poultry from ALL FARM ANIMAL HEALTH containing generic levamisole.
Levamisole is a veteran anthelmintic. It was introduced by JANSSEN already in the 1960s (NILVERM, RIPERCOL). It has a broad-spectrum of activity against roundworms (gastrointestinal and pulmonary) but no efficacy whatsoever against tapeworms and flukes. It is also completely ineffective against external parasites of livestock (ticks, flies, lice, mites, etc). Levamisole has been used massively worldwide in countless generic formulations for livestock. It still remains one of the most preferred low-cost anthelmintics for livestock worldwide. Usage in pets or horses is rather scarce. It is not used in agriculture.
As many other anthelmintics (e.g. benzimidazoles, tetrahydropyrimidines) levamisole administered orally has no residual effect, i.e. it kills the parasites shortly after administration, but does not significantly protect the animals against re-infestation by infective stages in their environment.
