The egg reappearance period of small strongyles is 90 days.
The veterinary medicinal product is effective against (developing) intramucosal L4 stages
of small strongyles. At 8 weeks after treatment, early (hypobiotic) EL3 stages of small
strongyles are eliminated.
A single oral dose of 400 µg moxidectin/kg body weight and 2.5 mg praziquantel/kg body
weight using the calibrated syringe of one gradation per 25 kg live weight.
A single syringe treats a 700 kg horse.
To ensure administration of a correct dosage, body weight should be determined as
accurately as possible; accuracy of the dosing should be checked.
Use of a scale or weight tape is recommended to ensure accurate dosing.
Dosing instructions:
Before the first dose, hold the syringe with the capped end pointing to the left and so that
you can see the weight measurements and tick marks (small black lines). Set the syringe
to zero by moving the dial ring so the left side is set at the first full black mark and depress
the plunger, safely discarding any paste that is expelled.
To dose the veterinary medicinal product, hold the syringe as previously described. Each
tick mark relates to 25 kg of body weight and to 10 mg moxidectin/62.5 mg praziquantel.
Turn the dial ring until the left side of the ring lines up with the weight of the animal.
In the case of cestode treatment the dose of praziquantel in the veterinary medicinal
product has been selected to the top end of the dosing range.
Veterinary advice should be given on appropriate dosing programmes and stock
management to achieve optimum parasite control.
Do not administer to young foals less than 6.5 months old.
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.
The veterinary medicinal product has been formulated specifically for use in horses only.
Dogs and cats may be adversely affected by the concentration of moxidectin in this
veterinary medicinal product if they are allowed to ingest spilled gel or have access to
used syringes.
Horses:
Rare
(1 to 10 animals / 10,000 animals
treated):
Hypersalivation
, Mouth pain
Swollen muzzle
Ataxia
, Droopy lower lip
Anorexia
Very rare
(<1 animal / 10,000 animals treated,
including isolated reports):
Digestive tract disorder (e.g. colic, loose stool)
Tremor
Lethargy

These adverse effects are transient and disappear spontaneously.
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:
-
extended period of time;
-
the veterinary medicinal product, or lack of calibration of the dosing device (If any).
-
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.
For optimum control of bots, the veterinary medicinal product should be administered in
the autumn, after the end of the fly season and before spring as the larvae may start to
pupate and therefore are less sensitive to treatment.
Parasite resistance to a particular class of anthelmintic may develop following frequent,
repeated use of an anthelmintic of that class. The veterinarian should give advice regarding
appropriate dosing programmes and stock management to achieve adequate parasite control
for both tapeworm and roundworm infestations.

Special precautions for safe use in the target species:
To avoid overdosing, care should be taken to accurately dose foals, especially low body
weight foals or pony foals.
Do not use the same syringe to treat more than one animal unless horses are running
together or in direct contact with each other in the same premises.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals:
This veterinary medicinal product may cause eye irritation, skin irritation and skin
sensitisation.
Avoid contact with skin and eyes.
Personal protective equipment consisting of protective gloves should be worn when
handling the veterinary medicinal product. Wash hands or any exposed area after use.
Do not smoke, drink or eat while handling the veterinary medicinal product.
In case of eye contact, flush the eye with copious amounts of clean water and seek
medical advice immediately and show the package leaflet or the label to the physician.
In case of accidental ingestion, seek medical advice immediately and show the package
leaflet or the label to the physician.
Special precautions for the protection of the environment:
Moxidectin fulfils the criteria for a (very) persistent, bioaccumulative and toxic (PBT)
substance; therefore, exposure of the environment to moxidectin must be limited to the
extent possible. Treatments should be administered only when necessary and should be
based on faecal egg counts or evaluation of the risk of infestation at the animal and/or
herd level. In order to reduce the emission of moxidectin to surface water and based on
the excretion profile of moxidectin when administered as the oral formulation to horses,
treated animals should not have access to watercourses during the first week after
treatment.
Like other macrocyclic lactones, moxidectin has the potential to adversely affect non-target
organisms:
-
temporarily reduce the abundance of dung feeding organisms. Following treatment of
horses with the veterinary medicinal product, levels of moxidectin that are potentially
toxic to dung beetles and flies may be excreted over a period of more than 1 week
and may decrease dung fauna abundance.
-
medicinal product should be used only according to the label instructions.
In order to limit the impact of moxidectin on dung fauna, and due to insufficient data
regarding environmental risk of praziquantel, horses should not be turned out onto pasture
within 3 days of treatment.
The effects of GABA agonists are increased by moxidectin.
Do not store above 25 °C.
Meat and offal: 64 days.
Milk: Not authorised for use in animals producing milk for human consumption.
