Risk of resistance? YES, in gastrointestinal roundworms in sheep (very high), goats (very high) and cattle (high) particularly in:
- Sheep & goats: Haemonchus spp, Ostertagia spp /Teladorsagia spp, Trichostrongylus spp, Nematodirus spp, Chabertia ovina
- Cattle: Cooperia spp, Haemonchus spp, Oesophagostomum spp, Ostertagia spp, Trichuris spp
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
- Monepantel, only for sheep & goats in some countries (e.g. EU, Australia, New Zealand)
- 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.

GENERIC BRANDS available? YES, by the hundreds in the whole world. Ivermectin 1% injectable is probably the veterinary product with more generic brands worldwide.

ENDO-MECTIN injection is one of the numberless generic brands of the ivermectin 1% injectable formulation, in this case from ASPEN (manufactured by NORBROOK).
Whereas this type of ivermectin 1% injectables are approved for use on cattle worldwide, approval for use on sheep, swine & goats depends on the country. These differences are most likely due to marketing strategies of the different companies (e.g. market segmentation, local product portfolio, etc.) and not to regulatory hurdles.
Unfortunately, withholding periods for meat of the ivermectin 1% injectable vary considerably in different countries. This illustrates the fact that national regulatory authorities often draw different conclusions from exactly the same scientific evidence. This has been always so and there are no indications that things will improve in the near future.
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% injectable used at the recommended dose DOES NOT CONTROL:
- Ticks (e.g. Amblyomma spp, Rhipicephalus 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)
- Blowfly strike of sheep
- Tapeworms (e.g. Moniezia spp spp)
- Flukes (e.g. liver fluke Fasciola hepatica)
