WARNING !!!: Never use on humans, dogs and cats
Risk of resistance? YES, in gastrointestinal roundworms in sheep (very high), goats (very high) and cattle (high) particularly in:

- 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.
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
- 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, worldwide by the hundreds. Ivermectin 1% injectable is probably the veterinary product with more generic brands worldwide.

ANIMEC 1% injectable is one of the numberless generic brands of the ivermectin 1% injectable formulation, in this case from CHANELLE. It is a generic version of IVOMEC (from MERIAL).
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). Ivermectin was the first macrocyclic lactone discovered and introduced in the 1980s by MS&D AgVet (now MERIAL). 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 and, depending on the delivery form and formulation, also 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. It is massively used in livestock and horses, less in pets. Ist is also used as a human medicine, against agricultural and household pests and for vector control.
There are also numerous mixtures of ivermectin with other active ingredients, as well as other formulations for topical (pour-on) and oral (drench, feed additives) administration.
It is good to know that not all ivermectin 1% injectable formulations are exactly the same as the original formulation (IVOMEC). There are studies showing that the protective period (residual effect) against some particular parasites is considerably different among such formulations, indicating that they are not really bioequivalent. This can be due to different non-active ingredients in the formulation, different qualities of the active ingredient (e.g. with different by-products), different manufacturing processes, etc. Usually this is considered by the regulatory authorities of each country that issue the approved use instructions of every product, which may be different. It is also important to understand that although the product may control certain parasites, they may not be mentioned in the indications in a particular country simply because they do not occur there: e.g. cattle grubs in Australia and South America, human bot flies in Europe, North America and Australia, etc.
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 of 200 mcg/kg bw 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)
