Based on the very abundant and frequent use of levamisole 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.
- Benzimidazoles, e.g. albendazole, febantel, fenbendazole, oxfendazole, etc. Similar or even worse resistance problems than levamisole.
- Macrocyclic lactones e.g. abamectin, doramectin, eprinomectin, ivermectin, moxidectin. Similar or even worse resistance problems than levamisole.
- Nitroxinil (limited spectrum of activity).
- Tetrahydropyrimidines, e.g. morantel, pyrantel (limited spectrum of activity).
- Salicylanilides, e.g. closantel (limited spectrum of activity).
These alternative products may not be available in all countries, or may not be available as pour-ons.

SURESHOT GOLD Pour-on for Cattle from HUNTER RIVER COMPANY is one of the numerous wormers for livestock containing levamisole.
Levamisole is a veteran broad-spectrum anthelmintic active ingredient introduced already in the 1960s (by JANSSEN) 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).
Levamisole is mostly used in drenches for oral administration, and in some countries also in injectables. Pour-on administration is often more convenient than those other delivery forms, but has also disadvantages. In several scientific studies it has been shown that topically administered antiparasitics (e.g. ivermectin, fluazuron) are not "automatically" absorbed through the skin. Licking (self licking or licking of other treated animals) may account for >50% of the total intake. And individual cattle show a different licking behavior. An important practical consequence is that the quantity that is finally ingested and is therefore available for the control of gastrointestinal worms depends on the licking behavior of the treated animals. "High lickers" can be overdosed, whereas "low lickers" can be underdosed. And chronic underdosing of animals in a herd may enhance development of resistance to ivermectin in gastrointestinal roundworms. To our knowledge such effect of licking on topically administered levamisole has not been investigated but must be assumed.
Absorption through the skin is also negatively affected by the thickness of the skin and the hair coat, by dust and mud on the coat, by product lost on fences and yards, etc, factors that don't play a role after injection or drenching. In contrast with drenches or injectables, pour-on formulations should not be administered to wet animals, and rain shortly before (up to 6 hours) or after administration can cause product run-off and thus under-dosing. The pour-ons shouldn't be administered by strong winds that may blow away part of the product and/or contaminate the workers.
For all these reasons efficacy after pour-on administration is usually less reliable than after oral administration or injection.
