RESISTANCE PREVENTION

Resistance of gastrointestinal roundworms to levamisole (incl. abamectin) in sheep, goats and cattle has been reported almost worldwide, including the USA, UK, Australia and New Zealand. Based on the very abundant and frequent use of this compound in livestock it must be assumed that resistance of these roundworms to this chemical class will continue spreading and strengthening in the future.

This means that if this product does not achieve the expected efficacy against the mentioned parasites, it may be due to resistance and not to incorrect use, which is usually the most frequent cause of product failure.

COMMENTS

Levamisole is a veteran broad-spectrum anthelmintic active ingredient introduced already in the 1960s and since then massively used in livestock worldwide against gastrointestinal roundworms and lungworms. It has no efficacy whatsoever against flukes, tapeworms and against any external parasitres of livestock (ticks, flies, lice, etc).

For livestock levamisole is mostly used in drenches for oral administration and also in a few pour-ons for topical administration. There are also numerous mixtures of levamisole with other active ingredients.
