How Livestock Contract Liver Fluke

Animals are infected by ingesting encapsulated larvae (metacercariae) on contaminated grass. Typically,individual farms will have wet “flukey areas” that should not be used or grazed at times of the year when metacercariae are likely to be present, i.e. late summer to winter (depending on climatic conditions). However,cattle and sheep often graze on such areas. Therefore, it cannot be assumed that liver fluke infection is absent from any area of Ireland.

Summary of Product Characteristics

Trodax 340 mg/ml Solution for Injection

Active substance:
Nitroxynil 340 mg/ml
as N-ethylglucamine salt.

For a full list of excipients, see section 6.1

Solution for injection.
Bright orange-red solution

4.1 Target Species
Sheep and Cattle.

4.2 Indications for use, specifying the target species
Trodax 34% is indicated for the treatment of fascioliasis (infestation of mature and immature Fasciola hepatica) in
cattle and sheep.
It is also effective, at the recommended dose rate, against adult and larval infestations of Haemonchus contortus in cattle and sheep and Haemonchus placei, Oesophagostomum radiatum and Bunostomum phlebotomum in cattle.
However, Trodax should not be regarded or used as a broad spectrum anthelmintic.

4.3 Contraindications
Do not use in animals with known hypersensitivity to the active ingredient.
Do not exceed the stated dose.

4.4 Special warnings for each target species
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 bodyweight, misadministration of the product, or lack of
calibration of the dosing device.
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 tests strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

4.5 Special precautions for use
Special precautions for use in animals
Ensure the injection does not enter subcutaneous muscle.
Ewes in advanced pregnancy and not intended to produce milk for human consumption should be driven, handled and dosed carefully.
Estimate the weight of the sheep carefully and use injection equipment calibrated to accurately deliver the calculated
Special precautions to be taken by the person administering the veterinary medicinal product to animals
Trodax solution stains and care should be taken not to spill it, especially on the fleece of sheep.
Wash splashes from skin and eyes immediately.
Wear suitable gloves to avoid staining the skin.

4.6 Adverse reactions (frequency and seriousness)
Small swellings are occasionally observed at the injection site in cattle.
These can be avoided by injecting the dose in two separate sites and massaging well to disperse the solution.
No systemic ill effects are to be expected when animals (including pregnant cows and ewes) are treated at normal

4.7 Use during pregnancy, lactation or lay
The product is safe for use during pregnancy. However, the product is not permitted for use in animals producing milk
for human consumption, including pregnant animals intended to produce milk for human consumption.

4.8 Interaction with other medicinal products and other forms of interaction
No signs of incompatibility are to be expected if Trodax is administered to cattle or sheep concurrently with therapeutic 
doses of the following anthelmintics: levamisole and thiabendazole, or with clostridial vaccine.

4.9 Amounts to be administered and administration route
Administer by subcutaneous injection.
The standard dosage is 10mg nitroxynl per kilogram bodyweight.
If animals are to be treated collectively rather than individually, they should be grouped according to their bodyweight
and dosed accordingly, in order to avoid under- or overdosing.

Sheep: Administer according to the following doses scale:
Liveweight        Dose
14-20 kg           0.5ml
21-30kg            0.75ml
31-40kg           1.0 ml
41-55kg           1.5 ml
56-75kg           2.0 ml
over 75kg        2.5 ml

In outbreaks of fascioliasis each sheep in the flock should be injected immediately the presence of the disease is
recognised, repeating treatment as necessary throughout the period when infestation is occurring, at intervals of not less than one month.
On farms with fluke-infested pastures, routine preventative dosing should be carried out at intervals of not less than one month, having regard for such factors as the past disease history of the farm, the frequency and
severity of neighbouring outbreaks and regional forecasts of incidence.

Cattle: 1.5ml of Trodax 34% per 50 kg (1cwt) liveweight
Both infected and in-contact animals should be treated, treatment being repeated as considered necessary, though not more frequently than once per month.
The treatment of cattle helps to reduce contamination of pastures on farms where fascioliasis is endemic or certain roundworm occurrence is evident.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
In the event of accidental overdosage, the symptoms are pyrexia, rapid respiration and increased excitability.
Patients should be kept cool, and dextrose saline should be administered intravenously.

4.11 Withdrawal Period(s)
Sheep and cattle may be slaughtered for human consumption only after 60 days from the last treatment.
Not permitted for use in animals producing milk for human consumption, including pregnant animals intended to
produce milk for human consumption.

Phamacotherapeutic group:
Anthelmintics, nitroxinil.

ATCvet code:

5.1 Pharmacodynamic properties
The main pharmacological action of nitroxynil is fasciolicidal.
The lethal action against Fasciola hepatica has been demonstrated in vitro and in vivo in laboratory animals, and in sheep and cattle.
The mechanism of action is thought to be due to uncoupling of oxidative phosphorylation.
Few other pharmacodynamic effects have been observed at therapeutic doses.
Hyperpnoea and increased rectal temperature are seen at high doses, and near toxic doses cause an increase in blood pressure.

5.2 Pharmacokinetic properties
The pharmacokinetics of nitroxynil in sheep and cattle are very similar.

After subcutaneous injection of a single dose of 10mg/kg
peak plasma levels of 83.6ug/ml are achieved at 9.3 hours in sheep, and
peak plasma levels of 91.6ug/ml are achieved at 13 hours in cattle.

The plasma half lives are 5 days and 8 days in sheep and cattle respectively. This slow rate of elimination is in accordance with the observed long duration of action of Trodax against fluke in sheep and cattle.

 Cattle Injectables
Injectables should be given according to the manufacturer’s instructions at the recommended injection site.
• Always use a clean, sterile syringe and needle. If using a multiple injection gun, ensure the needle is disinfected between injections, e.g. with an automatic sterilisation system.
• If the site to be injected is dirty, clean the skin and swab with an alcohol-impregnated wipe or cotton wool.
• Before injecting, check the expiry date and read the instructions of the product to be used. Some products need to be shaken before use.
• Use the correct-sized needle according to the size of the animal and site of injection.
• Ensure the animal is adequately restrained before attempting the injection.
• Take care to ensure it is given subcutaneously and not intramuscularly. Raise a fold of skin at the injection site (mainly neck but some are ear) recommended by the product manufacturer and inject carefully into the space created.
• If a large dose is to be delivered, it may be advisable to split the dose between two injection sites. After the injection, briefly massage the site to improve the dispersal of the injected material.
• Dispose of the needle and syringe in appropriate clinical waste and sharps containers.

Sheep Subcutaneous injections
Subcutaneous injections need to be administered with care to ensure the product is placed under the skin and not into the fleece or muscle.
The sheep needs to be well restrained, and the skin ‘tented’ away from the underlying muscle.
The preferred injection site is 10–15 cm (4–6 inches) below the ear on the side of the neck (see diagram below). Usually a 1.6 cm (5/8 inch) needle is ideal.
After administration, the site should be gently massaged.
