Dosage:
The recommended dosage is 200 mcg/kg bw of ivermectin and 1 mg/kg bw of
praziquantel corresponding to 1.29 g of paste per 100 kg bodyweight in a single
administration.
Bodyweight and dosage should be accurately determined prior to treatment. For
syringes intended to treat horses up to 600 kg and 1100 kg, calibrated markings are
provided at 100 kg bodyweight intervals. For the syringe intended to treat horses up
to 750 kg, calibrated markings are provided at 125 kg bodyweight intervals. The
syringe should be adjusted to the calculated dosage by setting the ring on the
appropriate place on the plunger.
Method of administration:
To ensure a correct dosage, body weight should be determined as accurately as
possible.
While holding the plunger, turn the knurled ring on the plunger ¼ turn to the left and
slide it so the stop ring is at the prescribed weight marking. Lock the ring in place by
turning it ¼ turn to the right in order to bring the two arrows, the one visible on the
ring and the one on the plunger rod, into alignment. Make sure the horse’s mouth
contains no feed. Remove the cover from the tip of the syringe. Insert the syringe tip
into the horse’s mouth at the interdental space and deposit the paste on the base of
the tongue. Immediately raise the horse’s head for a few seconds after dosing and
ensure that the paste is consumed.
Parasite control Program
Veterinary advice should be given on appropriate dosing programs and stock
management to achieve adequate parasite control for both tapeworm and roundworm
infestations.
The veterinary medicinal product has been formulated for use in horses only. Cats,
Dogs, especially Collies, Old English Sheepdogs and related breeds or crosses, and
also turtles and tortoises 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.
Horses:
Rare
(1 to 10 animals / 10,000 animals
treated):
Oedema
; pruritus
Inflammation of the mouth, lip and tongue (e.g.,
oedema, hypersalivation, erythema, tongue
disorder and stomatitis)
Very rare
(<1 animal / 10,000 animals
treated, including isolated
reports):
Colic, loose stool
1
Can occur for some horses with heavy infestation of Onchocerca spp. microfilariae
following the treatment; such reactions were assumed to be the result of the death of
large numbers of microfilariae. These signs resolve within a few days but
symptomatic treatment may be advisable.
These reactions have been transitory in nature, appearing within 1 hour and abating
within 24 to 48 hours following administration. In case of severe oral reactions
symptomatic treatment is recommended.
Mild, transient signs may be observed in cases of heavy infestations with
tapeworms.
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.
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:
- 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 body weight,
misadministration of the veterinary medicinal product, or lack of
calibration of the dosing device (if any).
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 macrocyclic lactones (which includes ivermectin) has been reported in
Parascaris equorum
the use of this veterinary medicinal product should be based on local (regional, farm)
epidemiological information about susceptibility of gastro-intestinal nematodes and
recommendations on how to limit further selection for resistance to anthelmintics.
