Vectin is to be administered orally as a single treatment. The product contains a flavour and will be taken voluntarily by most horses. The product can either be administered by hand, similar to a treat, or mixed with a small amount of feed. It should be ensured that the horse consumes the entire dose.
Vectin can be used in horses with a bodyweight of 60 kg and above. To ensure administration of a correct dose, the body weight should be determined as accurately as possible.
The dose scheme provides for a minimum dose of 0.2 mg ivermectin per kg body weight. One chewable tablet is adequate for the treatment of up to 110 kg body weight. For higher body weights, a corresponding number of chewable tablets should be chosen according to the following dose scheme:
Body weight of the horse (kg): |

Contra-indications, warnings, etc
Do not use in horses weighing less than 60 kg.
Do not use in horses known to be hypersensitive to the active ingredient or any of the excipients.
Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
•Over-frequent and repeated use of anthelmintics from the same class, over an extended period of time.
•Underdosing, which may be due to underestimation of body weight or maladministration of the product.
Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. faecal egg count reduction test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.
Resistance to ivermectin has been reported in Parascaris equorum in horses. Therefore, the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.
Veterinary advice should be given on appropriate dosing programmes and stock management to achieve adequate parasite control and reduce the likelihood of anthelmintic resistance developing. In the event that a product is suspected of being ineffective, the animal owner is advised to seek veterinary advice.
After the administration of ivermectin to dogs, cases of intolerance with a fatal outcome have been reported, especially in Collies, Old English Sheepdogs and related breeds or crosses, and also in turtles/tortoises. Vectin is registered for horses and should not be used in other animal species.
Dogs or cats may be adversely affected by the ivermectin in this product if they are allowed to ingest dropped or discarded tablets or have access to used packaging material.
Occasionally, some horses heavily infected with Onchocerca microfilariae have developed oedema and pruritus following dosing, assumed to be due to the death of large numbers of microfilariae. These signs resolve within a few days but symptomatic treatment may be advisable.
On very rare occasions, colic, diarrhoea and anorexia have been reported post treatment, in particular when there is heavy worm burden. On very rare occasions, allergic reactions such as hypersalivation, lingual oedema and urticaria, tachycardia, congested mucous membranes, and subcutaneous oedema have been reported following treatment with the product.
Studies have demonstrated there are no adverse effects when horses are administered up to three times the recommended dose.
Mild transitory signs (slowed pupillary light response and depression) have been seen at a dose of 1.8 mg/kg. Other signs seen at higher doses include mydriasis, ataxia, tremors, stupor, coma and death. The less severe signs have been transitory. There is no known antidote but if signs of toxicity appear, symptomatic therapy is recommended.
