RESISTANCE PREVENTION

Risk of resistance? YES

Unfortunately, resistance of several gastrointestinal roundworms to ivermectin (and other macrocyclic lactones) is already very high and very frequent worldwide in sheep and goats.

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

Alternative chemical classes/active ingredients to prevent resistance of gastrointestinal roundworms through product rotation:

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.

COMMENTS

IVOMEC MAXIMIZER is a slow-release capsule brand from MERIAL with original ivermectin. Ensures 100 day control of ivermectin-sensitive strains of internal and external parasites.

Ivermectin was the first macrocyclic lactone introduced in the market in the early 1980s (by MSD AGVET, later MERIAL). It was a milestone and a tremendous progress that revolutionized the control of veterinary parasites. Depending on the delivery form and the dose it is effective against most species of roundworms that affect ruminants and against many external parasites (mainly lice, mites, etc), but not against tapeworms or flukes. Nowadays and worldwide there are hundreds if not thousands of veterinary antiparasitics for livestock, horses or pets containing ivermectin alone or in combination with other active ingredients. Ivermectin is also used in agricultural pesticides.
