to treat 600 kg of bodyweight.
Dosing Instructions: Each weight marking on the syringe plunger will deliver sufficient
paste to treat 100 kg bodyweight. Unlock the knurled ring by making ¼ turn and slide the
knurled ring up the plunger shaft so that the side nearest the barrel is at the prescribed
weight marking. Turn the knurled ring ¼ turn to lock in place. Make sure the horse’s mouth
contains no feed. Remove the plastic cap from the tip of the nozzle. Insert the syringe into
the horse’s mouth at the interdental space. Advance the plunger as far as it will go,
depositing the medication on the base of the tongue. Immediately raise the horse’s head
for a few seconds after dosing.
Parasite control program: All horses should be included in a regular parasite control
program with particular attention being paid to mares, foals and yearlings.
To ensure administration of a correct dose, bodyweight should be determined as
accurately as possible.

, Pruritus

Some horses carrying heavy infection of Onchocerca microfilariae have experienced
oedema and pruritus following dosing, assumed to be the result of death of large numbers
of microfilariae. These signs resolve within a few days, but symptomatic treatment may be
advisable.
Reporting adverse events is important. It allows continuous safety monitoring of a
veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to
either the marketing authorisation holder or its local representative or the national
competent authority via the national reporting system. See the package leaflet for
respective contact details.
development of resistance and could ultimately result in ineffective therapy:
- Too frequent and repeated use of anthelmintics from the same class, over an extended
period of time.
- Underdosing, which may be due to underestimation of bodyweight or misadministration
of the veterinary medicinal 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 (an avermectin) has been reported in Parascaris equorum in
horses in a number of countries, including the EU. Therefore, the use of this veterinary
medicinal 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.
Special precautions for safe use in the target species:
Where there is significant tissue damage following Habronema infestation, additional
medical therapies may be required.
Dogs or cats may be adversely affected by the concentration of ivermectin in this
veterinary medicinal product if they are allowed to ingest spilled paste or have access to
used syringes.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
Do not smoke, drink or eat while handling this veterinary medicinal product.
Wash hands after use.
