Risk of resistance? YES, resistance to tetrahydropyrimidines has been reported for Oesophagostomum spp in swine in a few countries (e.g. Denmark), with a certain degree of cross resistance with levamisole. But this probem is much less extended than resistance of gastrointestinal worms in sheep, goats and 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 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 external parasites through product rotation:
- Benzimidazoles (e.g. fenbendazole, oxfendazole, etc.)
- Macrocyclic lactones (mainy ivermectin)
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 brand from BOMAC for a medicated wormer containing generic morantel citrate.
Morantel (in this case the citrate salt) is a veteran anthelmintic introduced in the 1970s (by PFIZER → ZOETIS). It is a narrow-spectrum anthelmintic effective against roundworms in the gut, but not against those in other organs (skin, lungs, etc). Nowadays it is rather scarcely used in livestock, horses, or pets because more effective compounds with a broader spectrum are usually preferred. It is not used in agriculture.
Morantel has no residual effect, i.e. it kills the parasites after administration but as soon as medicated feeding is interrupted it does not significantly protect the animals against re-infestation by infective stages in their environment.
