Posology
Single administration.
200 µg of ivermectin and 1.5 mg of praziquantel per kg of bodyweight
corresponding to 1.07 g of gel per 100 kg bodyweight.
To ensure administration of a correct dose, body weight should be determined
as accurately as possible; accuracy of the dosing devices should be checked
as underdosing might lead to an increased risk of development of resistance
to anthelmintic drugs.

The first division delivers enough gel to treat 100 kg.
Each subsequent syringe division delivers enough gel to treat 50 kg of
bodyweight.
The syringe should be adjusted to the calculated dosage by setting the ring on
the appropriate place on the plunger.
The syringe containing 6.42 g of gel delivers sufficient paste to treat 600 kg of
bodyweight at the recommended dose rate.
The syringe containing 7.49 g of gel delivers sufficient paste to treat 700 kg of
bodyweight at the recommended dose rate.
Directions for use:
Oral use
Before the first administration, the syringe must be primed. Place the ring on
the first graduation mark and remove the first jet of paste by pressing the
plunger. The syringe is then ready for use.
Before administration, adjust the syringe to the calculated dosage by setting
the ring on the plunger. The gel is administered orally by inserting the nozzle
of the syringe through the interdental space and depositing the required
amount of gel on the back of the tongue. The animal's mouth should be free of
any food. Immediately after administration, elevate the head of the horse for a
few seconds to ensure the dose is swallowed.

Revised: January 2026
AN: 02497/2025
The veterinary surgeon should give advice regarding appropriate dosing
programmes and stock management to achieve adequate parasite control for
both tapeworm and roundworm infestations.

Do not use in foals under 2 weeks of age.
Do not use in mares from which milk is taken for human consumption.
Do not use in horses known to be hypersensitive to the active substances or to
any other ingredients.

Horses carrying heavy infection of have experienced
such reactions as swelling and itching after treatment. It is assumed that these
reactions are the result of the destruction of large numbers of microfilariae.
In case of very high levels of infestation, destruction of the parasites may
cause a mild transient colic and loose faeces in the treated horse.
Colic, diarrhoea and anorexia have been reported in very rare occasions post
treatment, in particular when there is heavy worm burden. In very rare
occasions, allergic reactions such as hypersalivation, lingual oedema and
urticaria, tachycardia, congested mucus membranes, and subcutaneous
oedema have been reported following treatment with the product.
A veterinarian should be consulted if these signs persist.

The product can be used safely in stallions.
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 an extended period of time.
•
misadministration of the 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 ivermectin (an avermectin) has been reported in Parascaris
equorum in horses in a number of countries including the EU. 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.

i. Special precautions for use in animals
Avermectins may not be well tolerated in all non-target species. Cases of
intolerance are reported in dogs, especially collies, old English sheepdogs and
related breeds or crosses and also in turtles and tortoises.
Dogs and cats should not be allowed to ingest spilled gel or access to used
syringes due to the potential for adverse effects related to ivermectin toxicity.
Parasite resistance to a particular class of anthelmintic may develop following
frequent, repeated use of an anthelmintic of that class.
ii. Special precautions to be taken by the person administering the veterinary
medicinal product to animals
Wash hands after use (to be sure that eye contamination cannot occur).
Avoid contact with the eyes. In the case of accidental contact, rinse with
abundant quantities of water. In case of eye irritation, seek medical attention.
Do not eat, drink or smoke while handling this product.
In the event of accidental ingestion, seek medical advice and show the
package leaflet to the doctor.
