Contraindications
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.
Vectin is registered for horses and should not be used
in other animal species. 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.
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.
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.
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.
Operator warnings
