Resistance of gastrointestinal roundworms to ivermectin 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 ivermectin and other macrocyclic lactones (with cross-resistance to ivermectin) 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 macrocyclic lactones
- Imidazothiazoles, mainly levamisole. etc. Similar or even worse resistance problems than macrocyclic lactones
- 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 injectables.
There are a few reports on liver fluke (Fasciola hepatica) resistance to clorsulon in sheep, but so far it is not such an extended problem as for gastrointestinal roundworms. To our knowledge there are no published reports on resistance of liver fluke (Fasciola hepatica) to clorsulon in cattle.
Are the active ingredients of this product ORIGINAL* or GENERICS**?
*Meaning that they are still patent protected and generics are not yet available
**Meaning that they have lost patent protection and may be acquired from manufacturers of generic active ingredients other than the holder of the original patent.

Ivermectin is a broad spectrum parasiticide with efficacy against internal parasites (mainly roundworms) and against external parasites as well (mainly mites, lice, grubs, etc). This is why it is called an endectocide (controls endoparasites and ectoparasites).
Clorsulon is a benzenesulphonamide with a narrow spectrum of efficacy against a few trematode species. it has no efficacy whatsoever on roundworms (gastrointestinal, pulmonary, ocular, etc.) or tapeworms, nor on external parasites of cattle (mites, lice, ticks, grubs, etc).
The reason for mixing clorsulon to ivermectin is adding efficacy against liver flukes (Fasciola hepatica), because ivermectin is not effective against any fluke species. However, at the dose rate used in this product clorsulon ensures efficacy only against the adult stages of Fasciola hepatica, but not against larvae. This is important because the most damaging stages of Fasciola hepatica are precisely the larvae migrating through the liver tissues. Adult liver flukes dwell mainly in the biliary ducts and are also damaging to cattle but substantially less than immature stages. Consequently cattle treated with this product won't be protected against immature liver flukes. There are products containing clorsulon that are also effective against late immature stages (≥8 weeks) of Fasciola hepatica, (e.g. various drenches). So far only flukicides containing triclabendazole are effective against all immature stages (≥1 week) of Fasciola hepatica, but are only available as drenches or pour-ons, not as injectables. However, cases of resistance of Fasciola hepatica to triclabendazole in cattle have already been reported in several countries (e.g. Australia, The Netherlands, Argentina, Peru).
Being one of the best antiparasitics ever developed, ivermectin does not control all parasites of livestock. Unfortunately advertising and even the label of some generic formulations in less developed countries often include unsubstantiated claims. To help preventing confusion and misuse it is useful to know that whatever ivermectin 1% + clorsulon 10% injectable formulation administered at the usual recommended dose of 1 ml/50 kg bw DOES NOT CONTROL:
- Ticks (most species, e.g. Amblyomma spp, Dermacentor spp, Haemaphysalis spp, Hyalomma spp, Ixodes spp, etc.)
- Flies (e.g. horn flies, houseflies, stable flies, black flies, horse flies, etc.)
- Fleas (e.g. Ctenocephalides spp)
- Tapeworms (e.g. Moniezia spp spp)
