Risk of resistance? NO
Resistance of gastrointestinal roundworms to ivermectin has not been reported yet in swine, in contrast with sheep, goats, cattle and horses, where it is very frequent worldwide.
This means that if this product does not achieve the expected efficacy against the mentioned parasites, it is likely to be due to incorrect use not to resistance
Alternative chemical classes/active ingredients to prevent resistance of gastroinitestinal roundworms through product rotation:
- Benzimidazoles, e.g. albendazole, febantel, fenbendazole, oxfendazole, etc. Similar or even worse resistance problems than macrocyclic lactones
- Imidazothiazoles, mainly levamisole. etc. Similar or even worse resistance problems than macrocyclic lactones
- Tetrahydropyrimidines, e.g. morantel, pyrantel (limited spectrum of activity)
These alternative products may not be available in all countries, or may not be available as injectables.
Although strictly speaking it is not yet needed, it may be advisable to rotate occasionally.

IVOMEC PREMIX is the original 0.6% ivermectin premix formulation for swine.
Ivermectin was the first macrocyclic lactone discovered and introduced in the 1980s by MS&D AgVet. It is the parasiticide for livestock and pets most widely used worldwide, with probably thousands of generic brands. Ivermectin is probably the best veterinary parasiticide ever developed, highly effective against roundworms as well as against numerous external parasites (ticks, flies, lice, mites, etc.). As all macrocyclic lactones, ivermectin used alone is ineffective against tapeworms and flukes, regardless of the delivery form.
There are also numerous mixtures of ivermectin with other active ingredients (not as a premix for swine) as well as other formulations (injectables, pour-ons, drenches, feed additives).
