This product is a classic oral anthelmintic for poultry from JAYCHEM 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.
